28-531: Script Editor (called AppleScript Editor from 2009 to 2014) is a code editor for the AppleScript and Javascript for Automation scripting languages, included in classic Mac OS and macOS . AppleScript Editor provides basic debugging capabilities and can save AppleScripts as plain text (.applescript), as a compiled script (.scpt), as a script bundle (.scptd), or as an application (.app). AppleScript Editor also handles script dictionary files, allowing

56-722: A graphical user interface (gvim), limited integrated development environment -like features, mouse interaction (both with and without the GUI), folding , editing of compressed or archived files in gzip , bzip2 , zip , and tar format and files over network protocols such as SSH , FTP , and HTTP , session state preservation, spell checking , split (horizontal and vertical) and tabbed windows, Unicode and other multi-language support, syntax highlighting , trans-session command, search and cursor position histories , multiple level and branching undo/redo history which can persist across editing sessions, and visual mode. While running, Vim saves

84-428: A text user interface ; its GUI mode, gVim , adds menus and toolbars for commonly used commands but the full functionality is still expressed through its command line mode. Vi (and by extension Vim) tends to allow a typist to keep their fingers on the home row , which can be an advantage for a touch typist . Vim has a built-in tutorial for beginners called vimtutor, which is usually installed along with Vim, but

112-466: A LSP server. This allows for source code editors to easily support more languages with syntax highlighting, refactoring, and reference finding. Many source code editors such as Neovim and Brackets have added a built-in LSP client while other editors such as Emacs, vim, and Sublime Text have support for an LSP Client via a separate plug-in. In 1985, Mike Cowlishaw of IBM created LEXX while seconded to

140-640: A basic form of functional programming , and Vim script has lambda since version 8.0. Vim script is mostly written in an imperative programming style . Vim macros can contain a sequence of normal-mode commands, but can also invoke ex commands or functions written in Vim script for more complex tasks. Almost all extensions (called plugins or more commonly scripts) of the core Vim functionality are written in Vim script, but plugins can also utilize other languages like Perl , Python , Lua , Ruby , Tcl , or Racket . These plugins can be installed manually, or through

168-421: A convenient way to run a compiler , interpreter , debugger , or other program relevant for the software-development process . So, while many text editors like Notepad can be used to edit source code, if they do not enhance, automate or ease the editing of code, they are not source-code editors . Structure editors are a different form of source-code editor, where instead of editing raw text, one manipulates

196-587: A plugin manager such as Vundle, Pathogen, or Vim-Plug. Vim script files are stored as plain text, similarly to other code, and the filename extension is usually .vim . One notable exception to that is Vim's config file, .vimrc . While vi was originally available only on Unix operating systems, Vim has been ported to many operating systems including AmigaOS (the initial target platform), Atari MiNT , BeOS , DOS , Windows starting from Windows NT 3.1 , OS/2 , OS/390 , MorphOS , OpenVMS , QNX , RISC OS , Linux , BSD , and Classic Mac OS . Also, Vim

224-460: A significant part of internet culture and they often start whenever either editor is mentioned anywhere. Vim (text editor) Vim ( / v ɪ m / ; vi improved ) is a free and open-source , screen-based text editor program. It is an improved clone of Bill Joy 's vi . Vim's author, Bram Moolenaar , derived Vim from a port of the Stevie editor for Amiga and released

252-542: A standalone source-code editor, an IDE typically also includes debugger and build tools. Standalone source code editors are preferred over IDEs by some developers when they believe the IDEs are bloated with features they do not need. Many source-code editors and IDEs have been involved in ongoing user arguments, sometimes referred to jovially as "holy wars" by the programming community. Notable examples include vi vs. Emacs and Eclipse vs. NetBeans . These arguments have formed

280-427: A tool for a specific task or adding a major flavour to its behaviour. Examples include Cream, which makes Vim behave like a click-and-type editor, or VimOutliner, which provides a comfortable outliner for users of Unix-like systems. Vim has a vi compatibility mode, but when that mode is not used, Vim has many enhancements over vi. However even in compatibility mode, Vim is not entirely compatible with vi as defined in

308-515: A version to the public in 1991. Vim is designed for use both from a command-line interface and as a standalone application in a graphical user interface . Since its release for the Amiga, cross-platform development has made it available on many other systems . In 2018, it was voted the most popular editor amongst Linux Journal readers; in 2015 the Stack Overflow developer survey found it to be

336-416: Is free software and its source code is available on GitHub . Neovim has the same configuration syntax as Vim prior to vim9script; thus the same configuration file can be used with both editors, although there are minor differences in details of options. If the added features of Neovim are not used, Neovim is compatible with almost all of Vim's features. The Neovim project was started in 2014, after

364-478: Is a separate executable and can be run with a shell command. The Vim Users' Manual details Vim's features and can be read from within Vim, or found online. Vim also has a built-in help facility (using the :help command) which allows users to query and navigate through commands and features. Vim features various special memory entries called registers (not to be confused with hardware or processor registers ). When cutting, deleting, copying, or pasting text

392-677: Is being entered and immediately warn of syntax problems. A few source-code editors compress source code, typically converting common keywords into single-byte tokens , removing unnecessary whitespace, and converting numbers to a binary form. Such tokenizing editors later uncompress the source code when viewing it, possibly prettyprinting it with consistent capitalization and spacing. A few source-code editors do both. The Language Server Protocol , first used in Microsoft's Visual Studio Code , allows for source code editors to implement an LSP client that can read syntax information about any language with

420-571: Is highly customizable and extensible, making it an attractive tool for users who demand a large amount of control and flexibility over their text editing environment. Text input is facilitated by a variety of features designed to increase keyboard efficiency. Users can execute complex commands with "key bindings," which can be customized and extended. The "recording" feature allows for the creation of macros to automate sequences of keystrokes and call internal or user-defined functions and mappings. Abbreviations, similar to macros and key mappings, facilitate

448-600: Is released under the Vim license , which includes some charityware clauses that encourage users who enjoy the software to consider donating to children in Uganda . The Vim license is compatible with the GNU General Public License through a special clause allowing distribution of modified copies under the GNU GPL version 2.0 or later . Like vi , Vim's interface is not based on menus or icons but on commands given in

476-470: Is shipped with Apple macOS . Independent ports of Vim are available for Android and iOS . Neovim is a fork of Vim that strives to improve the extensibility and maintainability of Vim. Some features of the fork include built-in Language Server Protocol (LSP) support, support for asynchronous I/O , and support for Lua scripting using luaJIT language interpreter. The project

504-401: Is the scripting language built into Vim. Based on the ex editor language of the original vi editor, early versions of Vim added commands for control flow and function definitions. Since version 7, Vim script also supports more advanced data types such as lists and dictionaries and a simple form of object-oriented programming . Built-in functions such as map() and filter() allow

532-491: The Oxford University Press . LEXX used live parsing and used color and fonts for syntax highlighting. IBM's LPEX (Live Parsing Extensible Editor) was based on LEXX and ran on VM/CMS , OS/2 , OS/400 , Windows , and Java Although the initial public release of vim was in 1991, the syntax highlighting feature was not introduced until version 5.0 in 1998. In 2003, Notepad++ , a source code editor for Windows,

560-584: The Single Unix Specification and POSIX (e.g., Vim does not support vi's open mode, only visual mode). Vim's developers state that it is "very much compatible with Vi". Some of Vim's enhancements include completion functions, comparison and merging of files (known as vimdiff), a comprehensive integrated help system, extended regular expressions , scripting languages (both native and through alternative scripting interpreters such as Perl, Python, Ruby, Tcl, etc.) including support for plugins ,

588-688: The code's structure, generally the abstract syntax tree . In this case features such as syntax highlighting, validation, and code formatting are easily and efficiently implemented from the concrete syntax tree or abstract syntax tree, but editing is often more rigid than free-form text. Structure editors also require extensive support for each language, and thus are harder to extend to new languages than text editors, where basic support only requires supporting syntax highlighting or indentation. For this reason, strict structure editors are not popular for source code editing, though some IDEs provide similar functionality. A source-code editor can check syntax while code

616-524: The expansion of short strings of text into longer ones and can also be used to correct mistakes. Vim also features an "easy" mode for users looking for a simpler text editing solution. There are many plugins available that extend or add new functionality to Vim. These plugins are usually written in Vim's internal scripting language, vimscript (also known as VimL), but can be written in other languages as well. There are projects bundling together complex scripts and customizations and aimed at turning Vim into

644-505: The source code for Stevie meant the program could be distributed without requiring the AT&;T source license. Basing his work on Stevie, Bram Moolenaar began working on Vim for the Amiga computer in 1988, with the first public release (Vim v1.14) in 1991. At the time of its first release, the name "Vim" was an acronym for "Vi IMitation", but this changed to "'Vi IMproved" late in 1993. Vim

672-629: The third most popular text editor, and in 2019 the fifth most popular development environment. Vim's forerunner, Stevie (ST Editor for VI Enthusiasts) , was created by Tim Thompson for the Atari ST in 1987 and further developed by Tony Andrews and G.R. (Fred) Walter. It was one of the first popularized clones of Vi , and did not use Vi's source code. The source code for Vi used the Ed text editor developed under AT&T, and therefore Vi could only be used by those with an AT&T source license. Basing Vim on

700-515: The user can choose to store the manipulated text in a register. There are 36 general-purpose registers associated with letters and numbers ([a-z0-9]) and a range of special ones that either contain special values (current filename, last command, etc.) or serve a special purpose. Like vi, vim supports multiple editing modes. Depending on the mode, typed characters are interpreted either as sequences of commands or are inserted as text. In Vim there are 14 editing modes, 7 basic modes and 7 variants: Vim

728-646: The user to see what scripting classes and commands are available for each scriptable application installed on the computer. Prior to Mac OS X 10.3 , Script Editor was developed using Carbon . 10.3 introduced a new Script Editor written using Cocoa . It was called AppleScript Editor from Mac OS X 10.6 to 10.10 , when the application added support for JavaScript for Automation. Source code editor Source-code editors have features specifically designed to simplify and speed up typing of source code, such as syntax highlighting , indentation , autocomplete and brace matching functionality. These editors also provide

756-430: The user's changes in a swap file with the ".swp" extension . This file can be used to recover after a crash. If a user tries to open a file and a swap file already exists, Vim will warn the user, and if the user proceeds, Vim will use a swap file with the extension ".swo" (or, if there is already more than one swap file, ".swn", ".swm", etc.). The feature can be disabled. Vim script (also called Vimscript or VimL )

784-497: Was released by Don Ho. The intention was to create an alternative to the java-based source code editor, JEXT In 2015, Microsoft released Visual Studio Code as a lightweight and cross-platform alternative to their Visual Studio IDE. In 2016, Visual Studio Code became the Microsoft product using the Language Server Protocol. A source-code editor is one component of a Integrated Development Environment. In contrast to
