Zeta makes writing extensions easier than standard C, although extension writers must adjust to a slightly different language. Our implementation runs zeta using a bytecode interpreter and is therefore limited in its performance; we plan to replace the bytecode interpreter with compilation to machine code, which should reduce the compilation time for a large program from tens of seconds to a fraction of a second. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of Zeta happened in <a href="../lists/labs.html#q=MIT">MIT</a> and <a href="../lists/labs.html#q=UCLA">UCLA</a> - Zeta is written in <a href="cpp.html">C++</a> - Read more about Zeta on the web: 1. 2. https://pdos.csail.mit.edu/archive/xoc/ 1. https://swtch.com/~rsc/papers/xoc-asplos2008.pdf 2. - 1 PLDB concepts link to Zeta: <a href="xoc-compiler.html">Xoc</a> Built with Scroll v178.2.3 04/19/2026 2026 410 2

By contrast, most existing tools for data-parallel computation embed a sublanguage of data-parallel pipelines in a general-purpose language, or vice versa. Yedalog extends Datalog, incorporating not only computational features from logic programming, but also features for working with data structured as nested records. Yedalog programs can run both on a single machine, and distributed across a cluster in batch and interactive modes, allowing programmers to mix different modes of execution easily. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"queryLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>queryLanguage</a> - Early development of Yedalog happened in <a href="../lists/labs.html#q=Google">Google</a> - See also: (1 related languages) <a href="datalog.html">Datalog</a> - Read more about Yedalog on the web: 1. https://research.google/pubs/pub43462/ 1. ```Example from the web: Documents = Load{path: "document-parse-trees"}; # Code to execute for each document: module PerDocument{tokens: T} = { # Computes parent-child relationships Child{p} = c :- T[c] == {parent: p, .._}; # Computes nodes that transitively descend from "influenced" Descendants{t: c} :- T[p] == {text: "influenced", .._}, c == Child{p}; Descendants{t: c} :- Descendants{t: p}, c == Child{p}; # Counts nodes in which each entity appears under the verb "influenced".

Johnson #99 on PLDB 51 Years Old 11k <span title="Yacc repos on GitHub.">Repos</span> Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system. It is a Look Ahead Left-to-Right (LALR) parser generator, generating a parser, the part of a compiler that tries to make syntactic sense of the source code, specifically a LALR parser, based on an analytic grammar written in a notation similar to Backus–Naur Form (BNF). Yacc itself used to be available as the default parser generator on most Unix systems, though it has since been supplanted as the default by more recent, largely compatible, programs..

Gray https://pldb.info/concepts/../lists/creators.html#q=Paul%20T.%20Graunke Paul T. Graunke #3747 on PLDB 26 Years Old We have designed and implemented xt3d, a highly declarative xml specification language. It demands little more from users than a knowledge of the expected input and desired output. We illustrate the power of xt3d with several examples, including one reminiscent of polytypic programming that greatly simplifies the import of xml values into general-purpose languages. . xt3d is itself an xml language, so users do not need to learn a new surface syntax. The principal advantage of xt3d over xslt is that it provides an extremely simple, declarative language for describing transformations over xml elements. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"grammarLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>grammarLanguage</a> - See also: (1 related languages) <a href="xslt.html">XSLT</a> - Read more about xt3d on the web: 1. http://cs.brown.edu/people/sk/Publications/Papers/Published/kgg-xt3d/paper.pdf 1. ```Example from the web: <xt3d-output> <ul> <li><xt3d-use name="name"/></li> <li><b><xt3d-use name="num"/></b> <xt3d-.../></li> <li><i><xt3d-use name="fmt"/></i> <xt3d-.../></li> </ul> </xt3d-output> ``` Built with Scroll v178.2.3 04/19/2026 2026 428 2.1

For instance, system-specific compilers find errors in Linux and other systems, and add support for specialized control flow to Qt and event-based programs. These compilers are difficult to build and cannot always understand each other’s language changes. However, they can greatly improve code understandability and correctness, advantages that should be accessible to all programmers. We describe an extension-oriented compiler for C called xoc. An extension-oriented compiler, unlike a conventional extensible compiler, implements new features via many small extensions that are loaded together as needed. Xoc gives extension writers full control over program syntax and semantics while hiding many compiler internals. Xoc programmers concisely define powerful compiler extensions that, by construction, can be combined; even some parts of the base compiler, such as GNU C compatibility, are structured as extensions. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"compiler"%5D%7D%5D%2C"logic"%3A"AND"%7D'>compiler</a> - Early development of Xoc happened in <a href="../lists/labs.html#q=MIT">MIT</a> and <a href="../lists/labs.html#q=UCLA">UCLA</a> - Xoc is written in <a href="zeta.html">Zeta</a> - Read more about Xoc on the web: 1. https://swtch.com/~rsc/papers/xoc-asplos2008.pdf 1.

Pierce #3745 on PLDB 23 Years Old XDuce is a statically typed programming language for XML processing. Its basic data values are XML documents, and its types (so-called regular expression types) directly correspond to document schemas. XDuce also provides a flexible form of regular expression pattern matching, integrating conditional branching, tag checking, and subtree extraction, as well as dynamic typechecking. We survey the principles of XDuce’s design, develop examples illustrating its key features, describe its foundations in the theory of regular tree automata, and present a complete formal definition of its core, along with a proof of type safety. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - See also: (1 related languages) <a href="dtd.html">DTD</a> - Read more about xduce on the web: 1. https://www.cis.upenn.edu/~bcpierce/papers/xduce-toit.pdf 1. ```Example from the web: addrbook[ person[name["Haruo Hosoya"], email["hahosoya@kyoto-u"], email["hahosoya@upenn"]], person[name["Benjamin Pierce"], email["bcpierce@upenn"], tel["123-456-789"]]] ``` Built with Scroll v178.2.3 04/19/2026 2026 369 1.8

The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit-based 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors.

Wyvern supports object capabilities, it is structurally typed, and aims to make secure way of programming easier than insecure - as described in the Wyvern Manifesto. One of the early available features that make Wyvern special is a way to safely use multiple programming languages within the same program so programmers can use the language most appropriate for each function while at the same time increasing the program's security.

The acronym is also used for any specific WSDL description of a web service (also referred to as a WSDL file), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly similar to that of a method signature in a programming language.

In fact it's just a shortcut for ;; void(0) in JS. nil ;; => void(0) ;; 2. Booleans - Wisp booleans true / false are JS booleans true ;; => true ;; 3. Numbers - Wisp numbers are JS numbers 1 ;; => 1 ;; 4. Strings - Wisp strings are JS Strings "Hello world" ;; Wisp strings can be multiline "Hello, My name is wisp!" ;; 5. Characters - Characters are sugar for JS single char strings \a ;; => "a" ;; 6. Keywords - Keywords are symbolic identifiers that evaluate to ;; themselves. :keyword ;; => "keyword" ;; Since in JS string constats fulfill this purpose of symbolic ;; identifiers, keywords compile to equivalent JS strings. (window.addEventListener :load handler false) ;; Keywords can be invoked as functions, that desugars to plain ;; associated value access in JS (:bar foo) ;; => foo["bar"] ;; 7. Vectors - Wisp vectors are JS arrays. [ 1 2 3 4 ] ;; Note: Commas are white space & can be used if desired [ 1, 2, 3, 4] ;; 8. Maps - Maps are hash maps, plain JS objects. Note that unlike ;; in clojure keys can not be of arbitary types. { "foo" bar :beep-bop "bop" 1 2 } ;; Commas are optional but can come handy for separating key value ;; pairs. { a 1, b 2 } ;; In a future JSONs syntax may be made compatible with map syntax. ;; 9. Lists - You can't have a lisp without lists! Wisp has lists too. ;; Wisp is homoiconic and it's code is made up of lists representing ;; expressions. The first item in the expression is a function, being ;; invoked with rest items as arguments. (foo bar baz) ; => foo(bar, baz); ;; # Conventions ;; Wisp puts a lot of effort in making naming conventions tra ``` Built with Scroll v178.2.3 04/19/2026 2026 784 3.9

Originally proposed by Niklaus Wirth in 1977 as an alternative to Backus–Naur form (BNF). It has several advantages over BNF in that it contains an explicit iteration construct, and it avoids the use of an explicit symbol for the empty string (such as <empty> or ε).WSN has been used in several international standards, starting with ISO 10303-21.

The language uses flow-sensitive typing also known as "flow typing." The Whiley project began in 2009 in response to the "Verifying Compiler Grand Challenge" put forward by Tony Hoare in 2003. The first public release of Whiley was in June, 2010.Primarily developed by David Pearce, Whiley is an open source project with contributions from a small community.

It is meant to enable executing code nearly as fast as running native machine code. It was envisioned to complement JavaScript to speed up performance-critical parts of web applications and later on to enable web development in languages other than JavaScript.

The dialect was very close to MSX BASIC. The major differences were the lack of the PLAY, SOUND, VPOKE and PUT SPRITE operators, the inability to open several files at the same time, and the inability to use more than one operator on one line.

It includes analog and mixed-signal extensions (AMS) in order to define the behavior of analog and mixed-signal systems (IEEE 1076.1-1999). The VHDL-AMS standard was created with the intent of enabling designers of analog and mixed signal systems and integrated circuits to create and use modules that encapsulate high-level behavioral descriptions as well as structural descriptions of systems and components.VHDL-AMS is an industry standard modeling language for mixed signal circuits.

In this paper, we describe a completely visual representation for lambda expressions, VEX, that has several advantages over traditional textual lambda calculus. Although VEX is designed as an expression-oriented component of VIPR [3, 4], it can also be used in teaching the concepts of lambda calculus as a replacement for or augmentation to the teaching of traditional textual rewrite rules. Many semantic issues in lambda calculus that are confusing to students, including substitution, free variables, and binding, become apparent and explicit in VEX. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"notation"%5D%7D%5D%2C"logic"%3A"AND"%7D'>notation</a> - Read more about VEX on the web: 1. http://users.encs.concordia.ca/~haarslev/vl95www/html-papers/citrin/citrin.html 1.

The format has been developed with the advent of large-scale genotyping and DNA sequencing projects, such as the 1000 Genomes Project. Existing formats for genetic data such as General feature format (GFF) stored all of the genetic data, much of which is redundant because it will be shared across the genomes.

Vala is syntactically similar to C# and includes several features such as: anonymous functions, signals, properties, generics, assisted memory management, exception handling, type inference, and foreach statements. Its developers Jürg Billeter and Raffaele Sandrini aim to bring these features to the plain C runtime with little overhead and no special runtime support by targeting the GObject object system.

It is within about 1 second of mean solar time at 0° longitude, and is not adjusted for daylight saving time. In some countries where English is spoken, the term Greenwich Mean Time (GMT) is often used as a synonym for UTC and predates UTC by nearly 300 years.The first Coordinated Universal Time was informally adopted on 1 January 1960 and was first officially adopted as CCIR Recommendation 374, Standard-Frequency and Time-Signal Emissions, in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967.The system has been adjusted several times, including a brief period where time coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972.

UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software in 1994–1995, with further development led by them through 1996. In 1997 UML was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since.

The acronym "TXL" originally stood for "Turing eXtender Language" after the language's original purpose, the specification and rapid prototyping of variants and extensions of the Turing programming language, but no longer has any meaningful interpretation. Modern TXL is specifically designed for creating, manipulating and rapidly prototyping language-based descriptions, tools and applications using source transformation.

It does so with extensions of Racket’s macro-definition forms that facilitate implementation of type rules alongside normal macro code. As a result, the macros implementing a new language directly type check the program during expansion, obviating the need to create and call out to a separate type checker. Thus, a complete typed language implementation remains a series of macro definitions that may be imported and exported in the standard way that Racket programmers are accustomed to. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"grammarLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>grammarLanguage</a> - Read more about turnstile on the web: 1. https://docs.racket-lang.org/turnstile/index.html 1. ```Example from the web: #lang turnstile (provide → Int λ #%app #%datum + ann) (define-base-type Int) (define-type-constructor → #:arity > 0) (define-primop + : (→ Int Int Int)) ; [APP] (define-typed-syntax (#%app e_fn e_arg ...) ≫ [⊢ e_fn ≫ e_fn- ⇒ (~→ τ_in ... τ_out)] #:fail-unless (stx-length=? #'[τ_in ...] #'[e_arg ...]) (format "arity mismatch, expected ~a args, given ~a" (stx-length #'[τ_in ...]) #'[e_arg ...]) [⊢ e_arg ≫ e_arg- ⇐ τ_in] ... -------- [⊢ (#%app- e_fn- e_arg- ...) ⇒ τ_out]) ; [LAM] (define-typed-syntax λ #:datum-literals (:) [(_ ([x:id : τ_in:type] ...) e) ≫ [[x ≫ x- : τ_in.norm] ... ⊢ e ≫ e- ⇒ τ_out] ------- [⊢ (λ- (x- ...) e-) ⇒ (→ τ_in.norm ... τ_out)]] [(_ (x:id ...) e) ⇐ (~→ τ_in ... τ_out) ≫ [[x ≫ x- : τ_in] ... ⊢ e ≫ e- ⇐ τ_out] --------- [⊢ (λ- (x- ...) e-)]]) ; [ANN] (define-typed-syntax (ann e (~datum :) τ:type) ≫ [⊢ e ≫ e- ⇐ τ.norm] -------- [⊢ e- ⇒ τ.norm]) ; [DATUM] (define-typed-syntax #%datum [(_ . n:integer) ≫ -------- [⊢ (#%datum- . n) ⇒ Int]] [(_ . x) ≫ -------- [#:error (type-error #:src #'x #:msg "Unsupported literal: ~v" #'x)]]) ``` Built with Scroll v178.2.3 04/19/2026 2026 497 2.5

For versions 6 and 7 (last), both a lower-priced Turbo Pascal and more expensive Borland Pascal were produced; Borland Pascal was more oriented towards professional software development, with more libraries and standard library source code. The name Borland Pascal is also used more generically for Borland's dialect of the Pascal programming language, significantly different from Standard Pascal.

Topic maps are organized around topics, which represent subjects of discourse; associations, representing relationships between the subjects; and occurrences, which connect the subjects to pertinent information resources. Topic maps may be represented in many ways: using Topic Maps syntaxes in files, inside databases, as internal data structures in running programs, and even mentally in the minds of humans.

TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation. For many applications, it is the most convenient way to program any TI calculator, since the capability to write programs in TI-BASIC is built-in.

It is a very versatile language with full support for table columns containing array data. It has inherent support for masked arrays, units, and astronomical coordinates. It has a very rich set of functions (like cone search and array reduction) making it very suitable for astronomical applications. User defined functions can be added easily. It also has full support of grouping/aggregation and nested queries. An operation that can be expressed in a single function is the matching of two sky catalogues. It can be used from C++, Python, and the Casacore program taql. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"queryLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>queryLanguage</a> - There is 1 <a href="jupyter-notebook.html">Jupyter</a> <a href="https://github.com/tammojan/taql-jupyter">Kernel</a> for Table Query Language - Read more about Table Query Language on the web: 1. https://casa.nrao.edu/aips2_docs/notes/199/node3.html 1.

In 2000, IBM renamed the existing System/390 to IBM eServer zSeries with the e depicted in IBM's red trademarked symbol, but because no specific machine names were changed for System/390, the zSeries name in common use refers only to the z900 and z990 generations of mainframes. In April 2006, with another generation of products, the official family was changed to IBM System z, which now includes both older IBM eServer zSeries models, the IBM System z9 models, the IBM System z10 models, and the newer IBM zEnterprise models.

The specification was based on an earlier proposal for an OWL rules language.SWRL has the full power of OWL DL, but at the price of decidability and practical implementations. However, decidability can be regained by restricting the form of admissible rules, typically by imposing a suitable safety condition.Rules are of the form of an implication between an antecedent (body) and consequent (head).

Does that mean it that the results are better with less samples?? 50 00:04:25,610 --> 00:04:31,190 I also removed a sample text-file which should have been classified as an NCL file. 51 00:04:31,000 --> 00:04:35,895 I think that probably made most of the difference, although I didn't test it atomically. 52 00:04:35,895 --> 00:04:38,370 Okay, that makes more sense. 53 00:04:39,515 --> 00:04:43,450 I don't get the same results for the text files. Full results here. 54 00:04:44,650 --> 00:04:50,000 They all look correctly classified to me, except for the ones in Fanghuan's repository. 55 00:04:50,000 --> 00:04:55,920 I manually went through all of the ones where I didn't already know based on the filename or the repository owner. 56 00:04:56,526 --> 00:05:00,000 [Presses button] It now correctly classifies all of my test files. 57 00:05:00,000 --> 00:05:05,970 R.

StoneCutter provides a familiar, C-like language construct by which to develop the implementation for individual, programmable instructions. The LLVM-based StoneCutter compiler performs individual instruction and whole-ISA optimizations in order to generate a high performance, Chisel HDL representation of the target design. Utilizing the existing Chisel tools, users can also generate C++ cycle accurate simulation models as well as Verilog representations of the target design. As a result, StoneCutter provides a very rapid design environment for development and experimentation. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"grammarLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>grammarLanguage</a> - Early development of StoneCutter happened in <a href="../lists/labs.html#q=Tactical Computing Laboratories LLC">Tactical Computing Laboratories LLC</a> - Read more about StoneCutter on the web: 1. https://dl.acm.org/doi/10.1145/3387902.3394029 1.

STELLA preserves those features of Common Lisp deemed essential for symbolic programming such as built-in support for dynamic data structures, heterogeneous collections, first-class symbols, powerful iteration constructs, name spaces, an object-oriented type system with a meta-object protocol, exception handling, and language extensibility through macros, but without compromising execution speed, interoperability with non-STELLA programs, and platform independence. STELLA programs are translated into a target language such as C++, Common Lisp, or Java, and then compiled with the native target language compiler to generate executable code. The language constructs of STELLA are restricted to those that can be translated directly into native constructs of the intended target languages, thus enabling the generation of highly efficient as well as readable code. As of Fall 2000, we have programmed approximately 100,000 lines of STELLA code - about 50% for the STELLA kernel itself and the other 50% for the PowerLoom knowledge representation system and related systems. Our subjective experience has been that it is only slightly more difficult to write and debug a STELLA program than a Lisp program, and that the inconvenience of having to supply some type information is much outweighed by the benefits such as catching many errors during compile time instead of at run time. The biggest benefit, however, seems to be that we can still leverage all the incremental code development benefits of Lisp, since we use the Common Lisp-based version of STELLA for prototyping. This allows us to incrementally define and redefine functions, methods and classes and to inspect, debug and fix incorrect code on the fly. Even the most sophisticated C++ or Java IDE's don't yet seem to support this fully incremental development style, i.e., a change in a class (every change in Java is a change to a class) still requires recompilation and restart of the application, and it is the restart that can be the most time consuming if one debugs a complex application that takes a significant time to reach a certain state. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of stella happened in <a href="../lists/labs.html#q=USC">USC</a> ```Example from the web: (defun (lisp-null-array-symbol-string STRING) ((rank INTEGER)) ;; Used in the lisp translation code, insdie a verbatim ;; to return Lisp-specific-code.

In practice, Stackless Python uses the C stack, but the stack is cleared between function calls . The most prominent feature of Stackless is microthreads, which avoid much of the overhead associated with usual operating system threads.

The language provides a linear format for the representation of the information normally displayed in a two-dimensional module inter-dependency diagram. In comparing SSL to FORTRAN or ALGOL, it is found to be largely complementary to the algorithmic (procedural) languages. SSL is capable of representing explicitly module interconnections and global data flow, information which is deeply imbedded in the algorithmic languages. On the other hand, SSL is not designed to depict the control flow within modules. The SSL level of software design explicitly depicts intermodule data flow as a functional specification. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of ssl-lang happened in <a href="../lists/labs.html#q=Science Applications, Inc">Science Applications, Inc</a> - Read more about ssl-lang on the web: 1. https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19760014843.pdf 1. ```Example from the web: a+b* 3.0 * sin ( r + 1.0) 2 * (ifix(c) + blank_coinmon.icount) name. feldl name set + [oe, fred) ``` Built with Scroll v178.2.3 04/19/2026 2026 348 1.7

Initially published in 1996 as an extension of SQL-92 (ISO/IEC 9075-4:1996, a version sometimes called PSM-96 or even SQL-92/PSM), SQL/PSM was later incorporated into the multi-part SQL:1999 standard, and has been part 4 of that standard since then, most recently in SQL:2016. The SQL:1999 part 4 covered less than the original PSM-96 because the SQL statements for defining, managing, and invoking routines were actually incorporated into part 2 SQL/Foundation, leaving only the procedural language itself as SQL/PSM.

SPIR-V is a new platform-independent intermediate language. It is a self-contained, fully specified, binary format for representing graphical-shader stages and compute kernels for multiple APIs. Physically, it is a stream of 32-bit words. Logically, it is a header and a linear stream of instructions. These encode, first, a set of annotations and decorations, and second a collection of functions. Each function encodes a control-flow graph (CFG) of basic blocks, with additional instructions to preserve source-code structured flow control. Load/store instructions are used to access declared variables, which includes all input/output (IO). Intermediate results bypassing load/store use single static-assignment (SSA) representation. Data objects are represented logically, with hierarchical type information: There is no flattening of aggregates or assignment to physical register banks, etc. Selectable addressing models establish whether general pointers may be used, or if memory access is purely logical. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"ir"%5D%7D%5D%2C"logic"%3A"AND"%7D'>intermediate representation language</a> - Early development of spir-v happened in <a href="../lists/labs.html#q=LunarG, Inc">LunarG, Inc</a> - See also: (1 related languages) <a href="spir.html">Standard Portable Intermediate Representation</a> - Read more about spir-v on the web: 1. https://www.khronos.org/registry/spir-v/papers/WhitePaper.html 1.

It would later be popular on other workstations. Spice Lisp evolved into CMUCL, a Common Lisp implementation..

Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s. First released in 1987, SPARC was one of the most successful early commercial RISC systems, and its success led to the introduction of similar RISC designs from a number of vendors through the 1980s and 90s.

For ANSI C, each Snowball script produces a program file and corresponding header file (with .c and .h extensions). The Snowball compiler checks the consistency of its script, and this check was used to discover a typo in a seminal academic paper by Lovins which had remained undetected for 30 years.The basic datatypes handled by Snowball are strings of characters, signed integers, and boolean truth values, or more simply strings, integers and booleans.

First defined by RFC 821 in 1982, it was last updated in 2008 with Extended SMTP additions by RFC 5321, which is the protocol in widespread use today. Although electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically use SMTP only for sending messages to a mail server for relaying.

Smalltalk was created as the language to underpin the "new world" of computing exemplified by "human–computer symbiosis." It was designed and created in part for educational use, more so for constructionist learning, at the Learning Research Group (LRG) of Xerox PARC by Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Scott Wallace, and others during the 1970s. The language was first generally released as Smalltalk-80.

Smalltalk MT adopts a different approach in that the Smalltalk source is compiled to machine code before being executed. This allows the developer the freedom of working with compiled code without the need for the traditional compile-link-run cycle.

In fact, this page has Tailwind's PlayCDN enabled – go to town experimenting! ## The basics ### Any line that starts with a `/` is a tag. By default, it will render a div, but you can name it anything you want: `/section`, `/MyComponent`, `/x-thing`. ### Attributes can follow: `/button hx-post="/clicked" hx-swap="outerHTML"` #### Common shorthands for classes and IDs: `/section #hero .rounded.bg-gray-200.p-4` #### Stacking, for organization ### Text at the end At the end of a tag, you can add ` = ` followed by anything except line breaks. This will be treated as innerText for that tag. `/section #hero .rounded.bg-gray-200.p-4` ``` Built with Scroll v178.2.3 04/19/2026 2026 484 2.4

Bernstein in 2012, in response to a spate of "hash flooding" denial-of-service attacks in late 2011.Although designed for use as a hash function in the computer science sense, SipHash is fundamentally different from cryptographic hash functions like SHA in that it is only suitable as a message authentication code: a keyed hash function like HMAC. That is, SHA is designed so that it is difficult for an attacker to find two messages X and Y such that SHA(X) = SHA(Y), even though anyone may compute SHA(X).

The notation is line- and indentation-sensitive, and it is intended to partially group input, but leave further parsing to another layer, especially enforestation. The parsed form of a shrubbery imposes grouping to ensure that further parsing is consistent with the shrubbery’s lines and indentation. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"dataNotation"%5D%7D%5D%2C"logic"%3A"AND"%7D'>dataNotation</a> - <a href="s-expressions.html">S-expressions</a> and <a href="python.html">Python</a> and <a href="i-expressions.html">I-expressions</a> and <a href="clojure.html">Clojure</a> influenced the design of Shrubbery Notation ```Example from the web: block: println("group within block") println("another group within block") if is_rotten(apple) | get_another() | take_bite() be_happy() match x | 0: let zero = x x + zero | n: n + 1 cond | // check the weather is_raining(): take_umbrella() | // check the destination going_to_beach(): wear_sunscreen() take_umbrella() | // assume a hat is enough ~else: wear_hat() ``` Built with Scroll v178.2.3 04/19/2026 2026 345 1.7

Like the Chef programming language, it is designed to make programs appear to be something other than programs; in this case, Shakespearean plays. A character list in the beginning of the program declares a number of stacks, naturally with names like "Romeo" and "Juliet".

The input to this subroutine consists of a string to be analyzed and a description of the syntax that is to be used. The syntax is expressed in the Shadow language. The output consists of a trace table that expresses the results of the syntactic analysis in a tabular form. Several versions of the subroutine and some associated programs have been in use now for over three years. The present account of the language and the subroutine contains a summary of material that has been described previously in unpublished reports and also some additional discussion of the work in relation to the more general questions of problem-oriented languages and string transformations. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of SHADOW happened in <a href="../lists/labs.html#q=MIT">MIT</a> - SHADOW on HOPL https://hopl.info/showlanguage.prx?exp=168 SHADOW on HOPL - Read more about SHADOW on the web: 1. https://dl.acm.org/doi/10.1145/368959.368992 1.

It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard.Since 2005 SHA-1 has not been considered secure against well-funded opponents, as of 2010 many organizations have recommended its replacement.

ISO 8879 Annex A.1 defines generalized markup: Generalized markup is based on two postulates: Markup should be declarative: it should describe a document's structure and other attributes, rather than specify the processing to be performed on it. Declarative markup is less likely to conflict with unforeseen future processing needs and techniques.

The most distinguishing feature of this language is the support it offers for sets and lists. As set theory is the language of mathematics, many mathematical algorithms that are formulated in terms of set theory have very straightforward implementations in SetlX. Designed mostly by Karl Stroetmann, the SetlX language is an evolution of Setl by Jack Schwartz. It was specifically conceived to make the unique features of Setl more accessible to today's computer science students. This interpreter is currently the SetlX reference implementation. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - setlx is developed on <a href="https://github.com/herrmanntom/setlX">GitHub</a> and has 26 stars - Early development of setlx happened in <a href="../lists/labs.html#q=https://github.com/herrmanntom/setlX/issues">https://github.com/herrmanntom/setlX/issues</a> - setlx is written in <a href="java.html">Java</a>, <a href="python.html">Python</a>, <a href="tex.html">Tex</a>, <a href="csv.html">CSV</a>, <a href="bash.html">Bash</a>, <a href="make.html">Make</a>, <a href="xml.html">XML</a>, <a href="bourne-shell.html">Bourne shell</a>, <a href="lisp.html">Lisp</a>, <a href="markdown.html">Markdown</a>, <a href="c.html">C</a> Built with Scroll v178.2.3 04/19/2026 2026 395 2

The SML specification defines model concepts, and the SML-IF specification describes a packaging format for exchanging SML-based models. SML and SML-IF were standardized in a W3C working group chartered to produce W3C Recommendations for the Service Modeling Language by refining the “Service Modeling Language” (SML) Member Submission, addressing implementation experience and feedback on the specifications.

Its main advantage is that it can be used to write straightforward code that automatically takes full advantage of all the processing power available, without programmers needing to be concerned with identifying parallelisms, specifying vectorization, avoiding race conditions, and other challenges of manual directive-based programming approaches such as OpenMP. Programs written in SequenceL can be compiled to multithreaded code that runs in parallel, with no explicit indications from a programmer of how or what to parallelize.

Here, we introduce Seq, the first language tailored specifically to bioinformatics, which marries the ease and productivity of Python with C-like performance. Seq is a subset of Python—and in many cases a drop-in replacement—yet also incorporates novel bioinformatics- and computational genomics-oriented data types, language constructs and optimizations. Seq enables users to write high-level, Pythonic code without having to worry about low-level or domain-specific optimizations, and allows for seamless expression of the algorithms, idioms and patterns found in many genomics or bioinformatics applications. On equivalent CPython code, Seq attains a performance improvement of up to two orders of magnitude, and a 175× improvement once domain-specific language features and optimizations are used. With parallelism, we demonstrate up to a 650× improvement. Compared to optimized C++ code, which is already difficult for most biologists to produce, Seq frequently attains up to a 2× improvement, and with shorter, cleaner code. Thus, Seq opens the door to an age of democratization of highly-optimized bioinformatics software. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Seq is developed on <a href="https://github.com/seq-lang/seq">GitHub</a> and has 698 stars - Early development of Seq happened in <a href="../lists/labs.html#q=MIT">MIT</a> - Seq is written in <a href="cpp.html">C++</a>, <a href="python.html">Python</a>, <a href="restructuredtext.html">reStructuredText</a>, <a href="json.html">JSON</a>, <a href="cmake.html">CMake</a>, <a href="markdown.html">Markdown</a>, <a href="typescript.html">TypeScript</a>, <a href="yaml.html">YAML</a>, <a href="bourne-shell.html">Bourne shell</a>, <a href="javascript.html">JavaScript</a>, <a href="make.html">Make</a>, <a href="dockerfile.html">Dockerfile</a> - Read more about Seq on the web: 1. http://cb.csail.mit.edu/cb/seq/oopsla19-paper34.pdf 1. ```Example from the web: from sys import argv from genomeindex import * # index and process 20-mers def process(kmer: k20, index: GenomeIndex[k20]): prefetch index[kmer], index[~kmer] hits_fwd = index[kmer] hits_rev = index[~kmer] ``` Built with Scroll v178.2.3 04/19/2026 2026 524 2.6

Self began as a dialect of Smalltalk, being dynamically typed and using just-in-time compilation (JIT) as well as the prototype-based approach to objects: it was first used as an experimental test system for language design in the 1980s and 1990s. In 2006, Self was still being developed as part of the Klein project, which was a Self virtual machine written fully in Self.

The rules are: the names of the rings must all be # lower-case letters, they must be input within 3 fields (representing the # towers) and delimited by 4 colons, such that the letters within each field # are in alphabetical order (i.e. rings are in descending order of size). # # For the benefit of anyone who wants to figure out the script, an "internal" # line of the form # b:0abx:1a2b3 :2 :3x2 # has the following meaning: the material after the three markers :1, :2, # and :3 represents the three towers; in this case the current set-up is # ":ab : :x :".

Whereas other flavors of JavaScipt are embedded in web browsers and restricted to scripts that have been transmitted along with HTML documents, the ScriptEase processor allows you to run scripts locally, so you can use ScriptEase to write full fledged programs. In addition, ScriptEase has added commands and directives that increase and extend its power without interfering with the operation of standard JavaScript. These enhancements include preprocessor directives such as #include and #define, the switch/case statement, and the built-in Buffer object. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of ScriptEase happened in <a href="../lists/labs.html#q=Nombas, Inc">Nombas, Inc</a> - ScriptEase on HOPL https://hopl.info/showlanguage.prx?exp=3619 ScriptEase on HOPL - Read more about ScriptEase on the web: 1. https://web.archive.org/web/20030417161951/http://www.nombas.com/us/company/company.htm 1. ```Example from the web: while( ThereAreUncalledNamesOnTheList() == true){ name=GetNameFromTheList(); CallthePerson(name); LeaveTheMessage(); } ``` Built with Scroll v178.2.3 04/19/2026 2026 333 1.7

The basic idea is that to minimise the number of characters in a program, the language should provide as many single-character instructions as possible. It was invented by Timwi in 2011. Sclipting is not considered finished as it can trivially be extended with more and more instructions assigned to new Chinese characters. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"esolang"%5D%7D%5D%2C"logic"%3A"AND"%7D'>esoteric programming language</a> - Early development of Sclipting happened in <a href="../lists/labs.html#q=https://github.com/Timwi/EsotericIDE/issues">https://github.com/Timwi/EsotericIDE/issues</a> Built with Scroll v178.2.3 04/19/2026 2026 277 1.4

They propose using the schema.org vocabulary along with the Microdata, RDFa, or JSON-LD formats to mark up website content with metadata about itself.

We propose a new probabilistic programming language for the design and analysis of perception systems, especially those based on machine learning. Specifically, we consider the problems of training a perception system to handle rare events, testing its performance under different conditions, and debugging failures. We show how a probabilistic programming language can help address these problems by specifying distributions encoding interesting types of inputs and sampling these to generate specialized training and test sets. More generally, such languages can be used for cyber-physical systems and robotics to write environment models, an essential prerequisite to any formal analysis. In this paper, we focus on systems like autonomous cars and robots, whose environment is a scene, a configuration of physical objects and agents. We design a domain-specific language, Scenic, for describing scenarios that are distributions over scenes. As a probabilistic programming language, Scenic allows assigning distributions to features of the scene, as well as declaratively imposing hard and soft constraints over the scene. We develop specialized techniques for sampling from the resulting distribution, taking advantage of the structure provided by Scenic's domain-specific syntax. Finally, we apply Scenic in a case study on a convolutional neural network designed to detect cars in road images, improving its performance beyond that achieved by state-of-the-art synthetic data generation methods. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of Scenic happened in <a href="../lists/labs.html#q=University of California Berkeley">University of California Berkeley</a> - Read more about Scenic on the web: 1. 2. 3. https://scenic-lang.readthedocs.io/en/latest/ 1. https://dl.acm.org/doi/10.1145/3314221.3314633 2. https://math.berkeley.edu/~dfremont/images/scenic-video-abstract.mp4 3.

Designed to be concise, many of Scala's design decisions aimed to address criticisms of Java.Scala source code is intended to be compiled to Java bytecode, so that the resulting executable code runs on a Java virtual machine. Scala provides language interoperability with Java, so that libraries written in both languages may be referenced directly in Scala or Java code.

In 1976 Turner redesigned and reimplemented it as a non-strict (lazy) language. In this form it was the foundation of Turner's later languages KRC and Miranda, but SASL appears to be untyped whereas Miranda has polymorphic types.

S2 source code is compiled into Perl, which the webserver can then execute directly for individual web page requests. The S2 system is, at its heart, completely general and can be used for almost any web application; however there exists no documentation for the implementation of S2 within other applications, which ties it relatively closely to LiveJournal.

Alternation, control flow and one-symbol look-ahead constructs are part of the language.

Davis #2890 on PLDB 34 Years Old S-Lang is an interpreted language that was designed from the start to be easily embedded into a program to provide it with a powerful extension language. Examples of programs that use S-Lang as an extension language include the jed text editor and the slrn newsreader. Although S-Lang does not exist as a separate application, it is distributed with a quite capable program called slsh (``slang-shell'') that embeds the interpreter and allows one to execute S-Lang scripts, or simply experiment with S-Lang at an interactive prompt. Many of the the examples in this document are presented in the context of one of the above applications. S-Lang was originally a stack language that supported a postscript-like syntax. For that reason, I named it S-Lang, where the S was supposed to emphasize its stack-based nature. About a year later, I began to work on a preparser that would allow one unfamiliar with stack based languages to make use of a more traditional infix syntax. Currently, the syntax of the language resembles C, nevertheless some postscript-like features still remain, e.g., the `%' character is still used as a comment delimiter. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of s-lang happened in <a href="../lists/labs.html#q=https://www.jedsoft.org/slang/mailinglists.html">https://www.jedsoft.org/slang/mailinglists.html</a> ```Example from the web: define init_array (a) { variable i, imax; imax = length (a); for (i = 0; i < imax; i++) { a[i] = 7; } } variable A = Int_Type [10]; init_array (A); ``` Built with Scroll v178.2.3 04/19/2026 2026 447 2.2

In the usual parenthesized syntax of Lisp, an s-expression is classically defined as an atom, or an expression of the form (x . y) where x and y are s-expressions.

For disambiguating between files with common extensions, linguist applies some heuristics and a statistical classifier. This process can help differentiate between, for example, .h files which could be either C, C++, or Obj-C. .sp Misclassifications can often be solved by either adding a new filename or extension for the language or adding more samples to make the classifier smarter. .sp .m4 -2 .ce _F_i_x_i_n_g _s_y_n_t_a_x _h_i_g_h_l_i_g_h_t_i_n_g .br Syntax highlighting in GitHub is performed using TextMate-compatible grammars. These are the same grammars that TextMate, Sublime Text and Atom use. Every language in languages.yml is mapped to its corresponding TM `scope`. This scope will be used when picking up a grammar for highlighting. .sp Assuming your code is being detected as the right language, in most cases this is due to a bug in the language grammar rather than a bug in Linguist. _g_r_a_m_m_a_r_s_._y_m_l lists all the grammars we use for syntax highlighting on github.com. Find the one corresponding to your code's programming language and submit a bug report upstream. .sp If you can, try to reproduce the highlighting problem in the text editor that the grammar is designed for (TextMate, Sublime Text, or Atom) and include that information in your bug report. .sp You can also try to fix the bug yourself and submit a Pull Request. TextMate's documentation offers a good introduction on how to work with TextMate-compatible grammars. You can test grammars using Lightshow. .sp Once the bug has been fixed upstream, we'll pick it up for GitHub in the next release of Linguist. .sp 2 .ce _T_e_s_t_i_n_g .br For development you are going to want to checkout out the source.

It was created by Chad Fowler and Richard Kilmer during RubyConf 2004.The interface for RubyGems is a command-line tool called gem which can install and manage libraries (the gems). RubyGems integrates with Ruby run-time loader to help find and load installed gems from standardized library folders.

Rise provides a set of data-parallel high-level patterns that are used to describe computations over higher dimensional arrays (aka tensors) in an abstract way. For example, the map pattern applies a given function to every element of the input array. The zip pattern combines two input arrays pairwise to produce an output array of pairs. The reduce pattern is customized with a binary reduction operator (such as addition), a matching neutral element (such as zero), and an input array that is reduced to a single value (such as the sum of all elements). - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of rise happened in <a href="../lists/labs.html#q=University of Glasgow">University of Glasgow</a> - Read more about rise on the web: 1. https://michel.steuwer.info/files/publications/2020/accML.pdf 1. ```Example from the web: fun(A : N.K.float => fun(B : K.M.float => A |> map(fun(arow => B |> map(fun(bcol => zip(arow, bcol) |> map(*) |> reduce(+, 0) )) )))) ``` Built with Scroll v178.2.3 04/19/2026 2026 353 1.8

give an overview of how to contribute to SciPy. It tries to answer commonly asked questions, and provide some insight into how the community process works in practice. Readers who are familiar with the SciPy community and are experienced Python coders may want to jump straight to the `git workflow`_ documentation. Contributing new code --------------------- If you have been working with the scientific Python toolstack for a while, you probably have some code lying around of which you think "this could be useful for others too". Perhaps it's a good idea then to contribute it to SciPy or another open source project. The first question to ask is then, where does this code belong? That question is hard to answer here, so we start with a more specific one: *what code is suitable for putting into SciPy?* Almost all of the new code added to scipy has in common that it's potentially useful in multiple scientific domains and it fits in the scope of existing scipy submodules. In principle new submodules can be added too, but this is far less common. For code that is specific to a single application, there may be an existing project that can use the code. Some scikits (`scikit-learn`_, `scikits-image`_, `statsmodels`_, etc.) are good examples here; they have a narrower focus and because of that more domain-specific code than SciPy. Now if you have code that you would like to see included in SciPy, how do you go about it? After checking that your code can be distributed in SciPy under a compatible license (see FAQ for details), the first step is to discuss on the scipy-dev mailing list. All new features, as well as changes to existing code, are discussed and decided on there. You can, and probably should, already start this discussion before your code is finished. Assuming the outcome of the discussion on the mailing list is positive and you have a function or piece of code that does what you nee ``` ```Example from <a href='https://en.wikipedia.org/wiki/ReStructuredText'>Wikipedia</a>: :: some literal text This may also be used inline at the end of a paragraph, like so:: some more literal text .. code:: python print("A literal block directive explicitly marked as python code") ``` Built with Scroll v178.2.3 04/19/2026 2026 1804 9

Usually this pattern is then used by string searching algorithms for "find" or "find and replace" operations on strings. The concept arose in the 1950s when the American mathematician Stephen Cole Kleene formalized the description of a regular language.

It introduces the concept of dialecting: small, optimized, domain-specific languages for code and data, which is also the most notable property of the language according to its designer Carl Sassenrath: Although it can be used for programming, writing functions, and performing processes, its greatest strength is the ability to easily create domain-specific languages or dialects Douglas Crockford, known for his involvement in the development of JavaScript, has described Rebol as "a more modern language, but with some very similar ideas to Lisp, in that it's all built upon a representation of data which is then executable as programs" and as one of JSON's influences. Originally, the language and its official implementation were proprietary and closed source, developed by REBOL Technologies.

RDoc includes the +rdoc+ and +ri+ tools for generating and displaying documentation from the command-line. == Generating Documentation Once installed, you can create documentation using the +rdoc+ command $ rdoc [options] [names...] For an up-to-date option summary, type $ rdoc --help A typical use might be to generate documentation for a package of Ruby source (such as RDoc itself). $ rdoc This command generates documentation for all the Ruby and C source files in and below the current directory. These will be stored in a documentation tree starting in the subdirectory +doc+. You can make this slightly more useful for your readers by having the index page contain the documentation for the primary file. In our case, we could type % rdoc --main README.rdoc You'll find information on the various formatting tricks you can use in comment blocks in the documentation this generates. RDoc uses file extensions to determine how to process each file. File names ending +.rb+ and +.rbw+ are assumed to be Ruby source. Files ending +.c+ are parsed as C files. All other files are assumed to contain just Markup-style markup (with or without leading '#' comment markers). If directory names are passed to RDoc, they are scanned recursively for C and Ruby source files only. To generate documentation using +rake+ see RDoc::Task. To generate documentation programmatically: gem 'rdoc' require 'rdoc/rdoc' options = RDoc::Options.new # see RDoc::Options rdoc = RDoc::RDoc.new rdoc.document options # see RDoc::RDoc == Writing Documentation To write documentation for RDoc place a comment above the class, module, method, constant, or attribute you want documented: ## # This class represents an arbitrary shape by a series of points. class Shape ## # Creates a new shape described by a +polyline+. # # If the +polyline+ does not end at the same point it started at the # first pointed is copied and placed at the end of the line. # # An ArgumentError is raised if the line crosses itself, but shapes may # be concave. def initialize polyline # ... end end The default comment markup format is the RDoc::Markup format. TomDoc[rdoc-ref:RDoc::TomDoc], Markdown[rdoc-ref:RDoc::Markdown] and RD[rdoc-ref:RDoc::RD] format comments are also supported. You can set the default comment format for your entire project by creating a <tt>.rdoc_options</tt> file. See RDoc::Options@Saved+Options for instructions on creating one. You can also set the comment format for a single file through the +:markup:+ directive, but this is only recommended if you wish to switch markup formats. See RDoc::Markup@Other+directives. Comments can contain directives that tell RDoc information that it cannot otherwise discover through parsing. See RDoc::Markup@Directives to control what is or is not documented, to define method arguments or to break up methods in a class by topic. See RDoc::Parser::Ruby for directives used to teach RDoc about metaprogrammed methods. See RDoc::Parser::C for documenting C extensions with RDoc. To determine how well your project is documented run <tt>rdoc -C lib</tt> to get a documentation coverage report. <tt>rdoc -C1 lib</tt> includes parameter names in the documentation coverage report. == Bugs See CONTRIBUTING@Bugs for information on filing a bug report. It's OK to file a bug report for anything you're having a problem with. If you can't figure out how to make RDoc produce the output you like that is probably a documentation bug. == License RDoc is Copyright (c) 2001-2003 Dave Thomas, The Pragmatic Programmers.

The signatures are written in .rbs files which is different from Ruby code. You can consider the .rbs files are similar to .d.ts files in TypeScript or .h files in C/C++/ObjC. The benefit of having different files is it doesn't require changing Ruby code to start type checking.

Qore is unique because it is an interpreted scripting language with fundamental support for multithreading (meaning more than one part of the same code can run at the same time), and additionally because it features automatic memory management (meaning programmers do not have to allocate and free memory explicitly) while also supporting the RAII idiom with destructors for scope-based resource management and exception-safe programming. This is due to Qore's unique prompt collection implementation for garbage collection..

Its name means heart and is a recursive acronym in Arabic meaning Qlb: a programming language (قلب: لغة برمجة, Qlb: Lughat Barmajah). It was developed in 2012 by Ramsey Nasser, a computer scientist at the Eyebeam Art + Technology Center in New York City, as both an artistic endeavor and as a response to the Anglophone bias in the vast majority of programming languages, which express their fundamental concepts using English words.

An interpreted language, Python has a design philosophy that emphasizes code readability (notably using whitespace indentation to delimit code blocks rather than curly brackets or keywords), and a syntax that allows programmers to express concepts in fewer lines of code than might be used in languages such as C++ or Java. It provides constructs that enable clear programming on both small and large scales.

PVS is based on a kernel consisting of an extension of Church's theory of types with dependent types, and is fundamentally a classical typed higher-order logic. The base types include uninterpreted types that may be introduced by the user, and built-in types such as the booleans, integers, reals, and the ordinals.

Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended as primarily a declarative programming language: the program logic is expressed in terms of relations, represented as facts and rules.

It should be noted that this format is egregiously inefficient. It is highly redundant, while containing a lot of information that the human eye can't even discern. Furthermore, the format allows very little information about the image besides basic color, which means you may have to couple a file in this format with other independent information to get any decent use out of it. However, it is very easy to write and analyze programs to process this format, and that is the point. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"textDataFormat"%5D%7D%5D%2C"logic"%3A"AND"%7D'>textDataFormat</a> - Early development of ppm-format happened in <a href="../lists/labs.html#q=https://netpbm.sourceforge.net/index.html#support">https://netpbm.sourceforge.net/index.html#support</a> - Read more about ppm-format on the web: 1. http://netpbm.sourceforge.net/doc/ppm.html 1. ```Example from the web: P3 # feep.ppm 4 4 15 0 0 0 0 0 0 0 0 0 15 0 15 0 0 0 0 15 7 0 0 0 0 0 0 0 0 0 0 0 0 0 15 7 0 0 0 15 0 15 0 0 0 0 0 0 0 0 0 ``` Built with Scroll v178.2.3 04/19/2026 2026 374 1.9

Fournier #52 on PLDB 40 Years Old ```Download source code: git clone https://github.com/postgres/postgres ``` PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. As a database server, its primary functions are to store data securely and return that data in response to requests from other software applications. It can handle workloads ranging from small single-machine applications to large Internet-facing applications (or for data warehousing) with many concurrent users; on macOS Server, PostgreSQL is the default database; and it is also available for Microsoft Windows and Linux (supplied in most distributions).

It was developed by researchers at the University of Utah in 1980, which released PSL 3.1; development was handed over to developers at Hewlett-Packard in 1982 who released PSL 3.3 and up. Portable Standard Lisp was available as a kit containing a screen editor, a compiler, and an interpreter for the 68000 processor architecture, DEC-20s, CRAY-1s, and the VAX architecture (among many others).

First, subsets such as Micro-Planner and Pico-Planner were implemented, and then essentially the whole language was implemented as Popler by Julian Davies at the University of Edinburgh in the POP-2 programming language. Derivations such as QA4, Conniver, QLISP and Ether (see Scientific Community Metaphor) were important tools in Artificial Intelligence research in the 1970s, which influenced commercial developments such as KEE and ART..

It was the first high-level (non-von Neumann) programming language to be designed for a computer. "Kalkül" means formal system – the Hilbert-style deduction system is for example originally called "Hilbert-Kalkül", so Plankalkül means "formal system for planning"..

There has been a progression from the original PL/S to the current PL/X.

AFAIK code exists written in all of the PL/* dialects and that the current PL/X compiler can handle all of them.

The use of esoteric distinguishes these languages from programming languages that working developers use to write software. Usually, an esolang's creators do not intend the language to be used for mainstream programming, although some esoteric features, such as visuospatial syntax, have inspired practical applications in the arts.

Piccola is small in the sense that its syntax is tiny, and it is pure in the sense that it provides only compositional features — computation is performed entirely by components of the host programming language. The semantics of Piccola is defined in terms of a process calculus, an extension of Milner’s pi calculus in which values communicated are forms, rather than tuples. A "form" is essentially an extensible nested record which also serves as a namespace in which expressions may be evaluated. This simple mechanism is responsible for much of the expressive power of Piccola. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of piccola happened in <a href="../lists/labs.html#q=RUniversitat ̈at Bern">RUniversitat ̈at Bern</a> Built with Scroll v178.2.3 04/19/2026 2026 300 1.5

The structure of phyloXML is described by XML Schema Definition (XSD) language. A shortcoming of current formats for describing phylogenetic trees (such as Nexus and Newick/New Hampshire) is a lack of a standardized means to annotate tree nodes and branches with distinct data fields (which in the case of a basic species tree might be: species names, branch lengths, and possibly multiple support values).

In our implementation, application programs use Patchwork to assemble complex microcode programs for a graphics processor from a library of microcode modules. We describe a simple and efficient implementation, in which the only overhead incurred is a single extra level of indirection when invoking a module or when a module accesses inputs, outputs, or local storage. The implementation depends on being able to describe a distinct execution tree for the network, which obviates the need both for run-time monitoring of the execution and for movement of data. Thus, neither dataflow hardware nor a dataflow language is needed for the implementation. Patchwork supports flow-of-control constructs such as looping and branching, the assembly of complex modules from simpler ones, modules written in a variety of languages for a variety of different devices, the interleaved execution of several programs on a single processor, and the execution of a single program on a set of processors in parallel. An analysis showed that Patchwork contributed between 2 and 5% to the total running time of sample microcode programs. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of Patchwork happened in <a href="../lists/labs.html#q=Lucasfilm">Lucasfilm</a> - Patchwork on HOPL https://hopl.info/showlanguage.prx?exp=6437 Patchwork on HOPL - Read more about Patchwork on the web: 1. http://www.sciencedirect.com/science/article/pii/0164121286900476/pdf?md5=16c0636d527cb9586f25153185f169a6&pid=1-s2.0-0164121286900476-main.pdf 1.

The complete methodology comprises the concurrent language Pamela (PerformAnce ModEling LAnguage), the program and machine modeling paradigm, and a novel performance analysis method, called "serialization analysis". While Pamela models can be directly executed (i.e., simulated), prior to this ultimate evaluation step, serialization analysis allows for (symbolic) model reduction, which often renders simulation superuous. This analysis method extends conventional parallel program analysis technology by explicitly accounting for the performance degrading e ects of resource contention, yet at the low evaluation cost, typical for conventional techniques. It is shown that, where application of conventional techniques may yield serious errors, predictions from serialization analysis remain accurate. Apart from the modeling methodology itself, this low-cost/high-reliability analysis potential makes Pamela a particularly suitable candidate for compile-time application in terms of the performance prediction hierarchy often found in parallel programming environments. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of PAMELA happened in <a href="../lists/labs.html#q=Delft University of Technology">Delft University of Technology</a> - PAMELA on HOPL https://hopl.info/showlanguage.prx?exp=5099 PAMELA on HOPL - Read more about PAMELA on the web: 1. 2. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.12.9900&rep=rep1&type=pdf 1. https://dl.acm.org/doi/10.1145/165939.166002 2.

PALcode is Alpha machine code, running in a special mode that also allows access to internal registers specific to the particular Alpha processor implementation. It is thus somewhere between the role of microcode and of a hardware emulator.

The name is used to encompass plain text files ("org files") that include simple marks to indicate levels of a hierarchy (such as the outline of an essay, a topic list with subtopics, nested computer code, etc.), and an editor with functions that can read the markup and manipulate hierarchy elements (expand/hide elements, move blocks of elements, check off to-do list items, etc.). Org-mode was created by Carsten Dominik in 2003, originally to organize his own life and work, and since the first release numerous other users and developers have contributed to this free software package.

A factor for the popularity of those markup formats is the widespread availability of simple, free packages for converting the formats to HTML. For example, the world of Ruby-powered websites has settled on RedCloth for converting Textile to HTML. The default way to convert org-mode files to HTML is the powerful publishing functionality provided by =emacs=. However, =emacs= does not easiliy integrate into many existing website frameworks. =Org-ruby= tries to make it easier to use org-mode files in both dyanmic and static website generation tools written in Ruby. =Org-ruby= is a simple Ruby gem to convert org-mode files to HTML. * Using Org-ruby =Org-ruby= follows the same model as other Ruby markup libraries. You install the gem: #+BEGIN_EXAMPLE sudo gem install org-ruby #+END_EXAMPLE Then, to convert an org-file to HTML in your Ruby code: #+BEGIN_EXAMPLE require 'rubygems' require 'org-ruby' data = IO.read(filename) puts Orgmode::Parser.new(data).to_html #+END_EXAMPLE * Walkthrough: Using org-ruby with Webby Here is an example of how to integrate =org-ruby= into Webby, a static website generation tool written in Ruby. Webby follows a similar pattern to other static site generation tools (like nanoc, Jekyll, and webgen): - You author website content in text with simple markup - Each page is fed through one or more /filters/ to produce HTML - The HTML is mixed in with layouts to produce the final pages For a Webby site, a the source for a page may look like this: #+BEGIN_EXAMPLE --- title: Special Directories created_at: 2009-12-17 status: Complete filter: - erb - maruku tags: - powershell --- <%= @page.title %> ================== Special Directories are a set of directories, each of which has a function that will navigate you to the appropriate directory using the push-location cmdlet. For example, the function `home` might navigate to `c:\users\bdewey.` Install ------- Copy the module to somewhere in `ENV:PSModulePath`. Then, InstallModule SpecialDirectories #+END_EXAMPLE In the above example, the text is written in Markdown. At the top of the file, metadata informs Webby to pass the text through two /filters/ to produce HTML. The first filter, =erb=, handles embedded Ruby. In this case, it will replace ~<%= @page.title %>~ with the page title (=Special Directories=). The second filter uses Maruku to translate Markdown into HTML. You can use the exact same pattern to include org-mode files in a Webby site. For this walkthrough, I assume you already have Webby installed, and that you've already created a site. 1. Make sure you have =org-ruby= installed: =sudo gem install org-ruby=. 2. You need to register a new Webby filter to handle org-mode content. Webby makes this easy. In the =lib/= folder of your site, create a file =orgmode.rb=: #+BEGIN_EXAMPLE require 'org-ruby' Webby::Filters.register :org do |input| Orgmode::Parser.new(input).to_html end #+END_EXAMPLE This code creates a new filter, =org=, that will use the =org-ruby= parser to translate org-mode input into HTML. 3. Create your content. For example: #+BEGIN_EXAMPLE --- title: Orgmode Parser created_at: 2009-12-21 status: Under development filter: - erb - org tags: - orgmode - ruby --- <%= @page.title %> Status: <%= @page.status %> * Description Helpful Ruby routines for parsing orgmode files. The most significant thing this library does today is convert orgmode files to textile. Currently, you cannot do much to customize the conversion. The supplied textile conversion is optimized for extracting "content" from the orgfile as opposed to "metadata." * History ** 2009-12-29: Version 0.4 - The first thing output in HTML gets the class "title" - HTML output is now indented - Proper support for multi-paragraph list items. See? This paragraph is part of the last bullet. - Fixed bugs: - "rake spec" wouldn't work on Linux. Needed "require 'rubygems'". #+END_EXAMPLE This file will go through the =erb= and =org= filters; as defined in the previous step, the =org= filter will use =org-ruby= to generate HTML. That's all there is to it! ``` ```Example from <a href='https://riju.codes/org'>Riju</a>: Hello, world! ``` ```Example from <a href='https://github.com/leachim6/hello-world/blob/main/o/Org-mode.org'>hello-world</a>: Hello World ``` Built with Scroll v178.2.3 04/19/2026 2026 1446 7.2

OSS transitioned to other platforms with Personal Pascal for the Atari ST and Personal Prolog for Macintosh (which was also advertised for the Atari ST, but may not have been released).

The OPS (said to be short for "Official Production System") family was developed in the late 1970s by Charles Forgy while at Carnegie Mellon. Allen Newell's research group in artificial intelligence had been working on production systems for some time, but Forgy's implementation, based on his Rete algorithm, was especially efficient, sufficiently so that it was possible to scale up to larger problems involving hundreds or thousands of rules.

It is designed with the needs of part-time or occasional programmers in mind. The language features are properly separated and their corner cases have been eliminated. This design means that if you only use Spice occasionally, you're likely to find it easy to come back to despite the breaks. The most similar well-known language is probably Common LISP together with CLOS. But Spice has a rich Algol-like external syntax, an XML transport form, and makes multiple values a key feature. The way Spice deals with multiple values is, we think, the feature that will strike most programmers as special. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"pl"%5D%7D%5D%2C"logic"%3A"AND"%7D'>programming language</a> - Early development of OpenSpice happened in <a href="../lists/labs.html#q=The OpenSpice Group">The OpenSpice Group</a> - OpenSpice on HOPL https://hopl.info/showlanguage.prx?exp=8619 OpenSpice on HOPL - Read more about OpenSpice on the web: 1. http://lambda-the-ultimate.org/node/516 1.

It is a script-only based modeller that uses its own description language; parts can be previewed, but it cannot be interactively selected or modified by mouse in the 3D view. An OpenSCAD script specifies geometric primitives (such as spheres, boxes, cylinders, etc.) and defines how they are modified and combined (for instance by intersection, difference, envelope combination and Minkowski sums) to render a 3D model.

It conforms to the international standard for ISLISP published jointly by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), ISO/IEC 13816:1997(E), revised to ISO/IEC 13816:2007(E).Written in the programming languages C and Lisp, it runs on most common operating systems. OpenLisp is designated an ISLISP implementation, but also contains many Common Lisp-compatible extensions (hashtable, readtable, package, defstruct, sequences, rational numbers) and other libraries (network socket, regular expression, XML, Portable Operating System Interface (POSIX), SQL, Lightweight Directory Access Protocol (LDAP)).OpenLisp includes an interpreter associated to a read–eval–print loop (REPL), a Lisp Assembly Program (LAP) and a backend compiler for the language C..

It is also supported by Otoy's Octane Render, V-Ray 3, and by the Cycles render engine in Blender (starting with Blender 2.65). OSL's surface and volume shaders define how surfaces or volumes scatter light in a way that allows for importance sampling; thus, it is well suited for physically-based renderers that support ray tracing and global illumination..

The language is based on Parsing Expression Grammars (PEGs) rather than Context-Free Grammars with the intent of providing “a natural and convenient way for programmers to implement tokenizers, parsers, visitors, and tree-transformers”.OMeta's main goal is to allow a broader audience to use techniques generally available only to language programmers, such as parsing. It is also known for its use in quickly creating prototypes, though programs written in OMeta are noted to be generally less efficient than those written in vanilla (base language) implementations, such as JavaScript.OMeta is noted for its use in creating domain-specific languages, and especially for the maintainability of its implementations (Newcome).

Its syntax is nearly identical to the Objective-C syntax and it shares with JavaScript the same relationship that Objective-C has with the C programming language: that of being a strict, but small, superset; adding traditional inheritance and Smalltalk/Objective-C style dynamic dispatch. Pure JavaScript, being a prototype-based language, already has a notion of object orientation and inheritance, but Objective-J adds the use of class-based programming to JavaScript.

Oberon was the result of a concentrated effort to increase the power of Modula-2, the direct successor of Pascal, and simultaneously to reduce its complexity. Its principal new feature is the concept of type extension of record types: It permits the construction of new data types on the basis of existing ones and to relate them, deviating from the dogma of strictly static data typing.

The format is being developed by Tim Berners-Lee and others from the Semantic Web community.

Typically, JavaScript is used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML and run client-side by a JavaScript engine in the user's web browser. Node.js lets developers use JavaScript to write Command Line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser.

It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible. In essence, Ninja is meant to replace Make, which is slow when performing incremental (or no-op) builds.

It features a powerful type system which can help eliminate many common bugs, such as null pointer dereferences and invalid casts, by detecting potential runtime errors at compile-time; the goal of the designers was to provide safety features comparable to those found in languages such as ML and Haskell, but using a more conventional syntax. Nice aims to be feature-rich, and as such, in addition to the common features of modern object-oriented programming languages, it implements contracts in the style of Eiffel, class extensibility through multimethods, and many concepts drawn from functional programming such as anonymous functions, tuples, pattern matching (“value dispatch”), and parametric polymorphism.

It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx runtime package. The latter offers the standard Rexx data type that combines string processing with unlimited precision decimal arithmetic.

The NetLinx controllers are rack mountable devices which run a version of VxWorks and integrate both a processor and device controllers and are typically utilized for audio-visual control systems. An example is the mid-range NetLinx Integrated NI-2100 controller which has 3 RS-232/RS-485 serial ports, 4 relays, 4 infrared/serial ports and 4 input/outputs.

NCL documents do not contain multimedia elements such as audio or video content; rather they function as a "glue" language that specifies how multimedia components are related. In particular, NCL documents specify how these components are synchronized relative to each other and how the components are composed together into a unified document.

Although often called "phonetic alphabets", spelling alphabets are unrelated to phonetic transcription systems such as the International Phonetic Alphabet. Instead, the International Civil Aviation Organization (ICAO) alphabet assigned codewords acrophonically to the letters of the English alphabet, so that critical combinations of letters and numbers are most likely to be pronounced and understood by those who exchange voice messages by radio or telephone, regardless of language differences or the quality of the communication channel.The 26 code words in the NATO phonetic alphabet are assigned to the 26 letters of the English alphabet in alphabetical order as follows: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.Strict adherence to the prescribed spelling words is required in order to avoid the problems of confusion that the spelling alphabet is designed to overcome.

The system ran on IBM S/360, S/370, and 4300-series mainframe hardware, and offered novel features (for the time) such as file access control and data compression. It was designed to allow academics and students to create and run their programs interactively on terminals, in an era when most mainframe computing was still being done from punched cards.

Move drastically reduces the Web3 learning curve and enables a developer experience of unprecedented ease. On a computer, everything is just bits and bytes and can be freely copied. You want a language that gives you the necessary abstractions around ownership and scarcity, just like in the physical world. You want those basic safety guarantees. That's what Move does and why we created a new language. These things are hard to recreate in other languages, including existing smart contract languages, and we wanted to design the entire language around providing these primitives so programmers can write code safely and efficiently and not have to reinvent the wheel every time they want to write some code. - Tags: <a href='../lists/explorer.html#searchBuilder=%7B"criteria"%3A%5B%7B"condition"%3A"contains"%2C"data"%3A"tags"%2C"origData"%3A"tags"%2C"type"%3A"string"%2C"value"%3A%5B"contractLanguage"%5D%7D%5D%2C"logic"%3A"AND"%7D'>contractLanguage</a> - Early development of Move happened in <a href="../lists/labs.html#q=Mysten Labs">Mysten Labs</a> ```Example from the web: module satoshi_flip::house_data { use sui::balance::{Self, Balance}; use sui::sui::SUI; use sui::coin::{Self, Coin}; use sui::package::{Self}; // Error codes const ECallerNotHouse: u64 = 0; const EInsufficientBalance: u64 = 1; } ``` Built with Scroll v178.2.3 04/19/2026 2026 366 1.8

The novel features of MOOSE include its ability to describe complex guards that may be used by an object to specify dynamic enabling conditions for its methods and may also be inherited selectively by a derived object. MOOSE is the first simulation environment to suggest the use of inheritance in driving parallel implementations of an object that may exploit specific knowledge about the application, architecture, or simulation algorithm to improve its efficiency. The paper introduces object-oriented design of simulation models, gives an overview of MOOSE, and illustrates its use in the design of parallel simulation models.
