NQP
Raku is a member of the Perl family of programming languages. Formerly named Perl 6, it was renamed in October 2019. Raku introduces elements of many modern and historical languages. Compatibility with Perl was not a goal, though a compatibility mode is part of the specification. The design process for Raku began in 2000. History The Raku design process was first announced on 19 July 2000, on the fourth day of that year's Perl Conference, by Larry Wall in his '' State of the Onion 2000'' talk. At that time, the primary goals were to remove "historical warts" from the language; "easy things should stay easy, hard things should get easier, and impossible things should get hard"; and a general cleanup of the internal design and application programming interfaces (APIs). The process began with a series of Request for Comments (RFCs). This process was open to all contributors, and left no aspect of the language closed to change. Once the RFC process was complete, Wall reviewed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rakudo
Rakudo is a Raku compiler targeting MoarVM, and the Java Virtual Machine, that implements the Raku specification. It is currently the only major Raku compiler in active development. Originally developed within the Parrot Parrots (Psittaciformes), also known as psittacines (), are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genus (biology), genera, found mostly in ... project, the Rakudo source code repository was split from the project in February 2009 so that it could be developed independently, although there were still many dependencies at the time. Rakudo is written in C, Raku, and the lightweight Raku subset NQP (Not Quite Perl). Rakudo Perl #14 was released in February 2009, codenamed ''Vienna'' after the Perl mongers group that had sponsored one of its developers since April 2008. Subsequent releases have used codenames based on Perl mongers groups. The first ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perl
Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl originally was not capitalized and the name was changed to being capitalized by the time Perl 4 was released. The latest release is Perl 5, first released in 1994. From 2000 to October 2019 a sixth version of Perl was in development; the sixth version's name was changed to Raku. Both languages continue to be developed independently by different development teams which liberally borrow ideas from each other. Perl borrows features from other programming languages including C, sh, AWK, and sed. It provides text processing facilities without the arbitrary data-length limits of ...

Multi-paradigm
Programming languages can be grouped by the number and types of Programming paradigm, paradigms supported. Paradigm summaries A concise reference for the programming paradigms listed in this article. * Concurrent programming language, Concurrent programming – have language constructs for concurrency, these may involve multi-threading, support for distributed computing, message passing, shared resources (including shared memory), or Futures and promises, futures ** Actor model, Actor programming – concurrent computation with ''actors'' that make local decisions in response to the environment (capable of selfish or competitive behaviour) * Constraint programming – relations between variables are expressed as constraints (or constraint networks), directing allowable solutions (uses constraint satisfaction or simplex algorithm) * Dataflow, Dataflow programming – forced recalculation of formulas when data values change (e.g. spreadsheets) * Declarative programming – describes ...

Sigil (computer Programming)
In computer programming, a sigil () is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo, where $ is the sigil. '' Sigil'', from the Latin '' sigillum'', meaning a "little sign", means ''a sign or image supposedly having magical power''. Sigils can be used to separate and demarcate namespaces that possess different properties or behaviors. Historical context The use of sigils was popularized by the BASIC programming language. The best known example of a sigil in BASIC is the dollar sign ("$") appended to the names of all strings. Many BASIC dialects use other sigils (like "%") to denote integers and floating-point numbers and their precision, and sometimes other types as well. Larry Wall adopted shell scripting's use of sigils for his Perl programming language. In Perl, the sigils do not specify fine-grained data types like strings and integers, but the more general categories of scalars (using a prefixed "$"), arra ...

Source Code Repository
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single server. Some of the metadata that a repository contains includes, among other things, a historical record of changes in the repository, a set of commit objects, and a set of references to commit objects, called ''heads''. The main purpose of a repository is to store a set of files, as well as the history of changes made to those files. Exactly how each version control system handles storing those changes, however, differs greatly. For instance, Subversion in the past relied on a database instance but has since moved to storing its changes directly on the filesystem. These differences in stora ...

Git (software)
Git () is a distributed version control software system, system that tracks versions of computer file, files. It is often used to control source code by Programmer, programmers who are software development, developing software collaboratively. Design goals of Git include speed, data integrity, and support for Distributed computing, distributed, non-linear workflows — thousands of parallel Branching (version control), branches running on different computers. "So I'm writing some scripts to try to track things a whole lot faster." As with most other distributed version control systems, and unlike most client–server systems, Git maintains a local copy of the entire Repository (version control), repository, also known as "repo", with history and version-tracking abilities, independent of Computer network, network access or a central Server (computing), server. A repository is stored on each computer in a standard directory (computing), directory with additional, Hidden f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mailing List
A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. Mailing lists are often rented or sold. If rented, the renter agrees to use the mailing list only at contractually agreed-upon times. The mailing list owner typically enforces this by " salting" (known as "seeding" in direct mail) the mailing list with fake addresses and creating new salts for each time the list is rented. Unscrupulous renters may attempt to bypass salts by renting several lists and merging them to find common, valid addresses. Mailing list brokers exist to help organizations rent their lists. For some list owners, such as specialized niche publications or charitable groups, their lists may be some of their most valuable assets, and mailing list brokers help them maximize the value of their lists. Transmission may be paper-based or electronic. Each has its strengths, although a 2022 article claimed that compared to email, " di ...

Libera Chat
Libera Chat, stylized as Libera.Chat, is an IRC network for free and open-source software projects. It was founded on 19 May 2021 by former Freenode staff members, after Freenode was taken over by Andrew Lee (entrepreneur), Andrew Lee, founder of Private Internet Access. History Freenode In 2017, Christel Dahlskjaer, then the head of staff at Freenode, incorporated a new company called Freenode Limited and transferred ownership to technology entrepreneur Andrew Lee (entrepreneur), Andrew Lee. In February 2021, Dahlskjaer added the logo of Shells, a company co-founded by Lee, to the Freenode website. Following criticism from staff, Dahlskjaer resigned from the leadership of Freenode, and Freenode staff elected Tom Wesley as the new head of staff. Lee allegedly removed a blog post explaining the leadership changes and, on 11 May, appointed a new person to oversee the Freenode infrastructure. Freenode staff members resigned en masse, and some published statements outlining th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Relay Chat
IRC (Internet Relay Chat) is a text-based chat system for instant messaging. IRC is designed for Many-to-many, group communication in discussion forums, called ''#Channels, channels'', but also allows one-on-one communication via instant messaging, private messages as well as Direct Client-to-Client, chat and data transfer, including file sharing. Internet Relay Chat is implemented as an application layer protocol to facilitate communication in the form of text. The chat process works on a Client–server model, client–server networking model. Users connect, using a clientwhich may be a Web application, web app, a Computer program, standalone desktop program, or embedded into part of a larger programto an IRC server, which may be part of a larger IRC network. Examples of ways used to connect include the programs Mibbit, KiwiIRC, mIRC and the paid service IRCCloud. IRC usage has been declining steadily since 2003, losing 60 percent of its users by 2012. In April 2011, the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exegesis
Exegesis ( ; from the Ancient Greek, Greek , from , "to lead out") is a critical explanation or interpretation (philosophy), interpretation of a text. The term is traditionally applied to the interpretation of Bible, Biblical works. In modern usage, exegesis can involve critical interpretations of virtually any text, including not just religious texts but also philosophy, literature, or virtually any other genre of writing. The phrase ''Biblical exegesis'' can be used to distinguish studies of the Bible from other critical textual explanations. Textual criticism investigates the history and origins of the text, but exegesis may include the study of the historical and cultural backgrounds of the author, text, and original audience. Other analyses include classification of the type of literary genres presented in the text and analysis of grammar, grammatical and syntax, syntactical features in the text itself. Usage One who practices exegesis is called an ''exegete'' (; from Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
