This package provides a major mode for editing abc music files. Includes some abc2midi features. Written for Emacs version 21. May or may not work with previous versions. See the Common Customizations section below. Or run `abc-customize'. This package is stored at https://github.com/mkjunker/abc-mode.

Js2 mode provides a JavaScript major mode for Emacs that is more advanced than the built-in javascript-mode. Features include accurate syntax highlighting using a recursive-descent parser, on-the-fly reporting of syntax errors and strict-mode warnings, smart line-wrapping within comments and strings, and code folding.

This package provides a major mode for editing and executing BQN code. It can be used to interactively evaluate BQN code in buffer or can be used to launch BQN REPL sessions. For evaluating BQN code or spawning interpreters an executable implementation is required such as cbqn or dbqn.

Emacs Org Roam is a solution for taking non-hierarchical notes with Org mode. Notes are captured without hierarchy and are connected by tags. Notes can be found and created quickly. Org Roam should also work as a plug-and-play solution for anyone already using Org mode for their personal wiki.

Polymode is an Emacs package that offers generic support for multiple major modes inside a single Emacs buffer. It is lightweight, object oriented and highly extensible. Creating a new polymode typically takes only a few lines of code. Polymode also provides extensible facilities for external literate programming tools for exporting, weaving and tangling.

This package enables you to associate file name patterns with external applications that are automatically invoked when you use commands like find-file. For example, you can have it open png files with feh and mp4 files with mpv. This is especially useful when browsing files with Dired.

This package adds supplemental Evil mode key-bindings to Emacs Org-mode. It features:

• normal, visual and insert mode bindings;

• key bindings organised in key themes;

• operators like > and < to work on headings;

• text objects;

• table support;

• calendar (date selection) support;

• agenda support.

This package provides an extensible means of specifying conditions which must be fulfilled before a task can be completed and actions to take once it is. Org Edna runs when either the BLOCKER or TRIGGER properties are set on a heading, and when it is changing from a TODO state to a DONE state.

Orgalist writes and manages Org mode's plain lists in non-Org buffers. More specifically, it supports the syntax of Org mode for numbered, unnumbered, description items, checkboxes, and counter cookies.

The library also implements radio lists, i.e., lists written in Org syntax later translated into the host format, e.g., LaTeX or HTML.

Outshine attempts to bring the look and feel of org-mode to an Emacs outside of the Org major-mode. It is an extension of outline-minor-mode (org-mode itself derives from outline-mode), so there is no such thing like an outshine mode, only outline-minor-mode with outshine extensions loaded.

This package provides a major mode for editing execline scripts.

Features:

• Syntax highlighting of commends, builtin commands and variable substitution.

• Completion of builtin commands.

• Working comment-region command.

• Indentation of blocks.

• Automatic enable of mode in *.exec files.

• Automatic enable of mode in files with execlineb interpreter.

inf-ruby provides a Read Eval Print Loop (REPL) buffer, allowing for easy interaction with a Ruby subprocess. Features include support for detecting specific uses of Ruby, e.g., when using Rails, and using an appropriate console.

If you are using Guix shell with manifest.scm, the inf-ruby-wrapper-command customization variable could be helpful.

Web mode is an Emacs major mode for editing web templates aka HTML files embedding parts (CSS/JavaScript) and blocks (pre rendered by client/server side engines). Web mode is compatible with many template engines: PHP, JSP, ASP, Django, Twig, Jinja, Mustache, ERB, FreeMarker, Velocity, Cheetah, Smarty, CTemplate, Mustache, Blade, ErlyDTL, Go Template, Dust.js, React/JSX, Angularjs, ejs, etc.

emacs-bind-map provides a macro bind-map which can be used to make a keymap available across different leader keys including ones tied to evil states. It is essentially a generalization of the idea of a leader key as used in Vim or the emacs-evil-leader package, and allows for an arbitrary number of leader keys.

This package maps ordinary graphemes (characters) to fancy ligatures, if both your version of Emacs and the font supports it. With this package you can control where Emacs must display ligatures. That is useful if you only want a subset of the ligatures in certain major modes, for instance, or if you want to ensure that some modes have no ligatures at all.

PHP mode is a major mode for editing PHP source code. It's an extension of C mode; thus it inherits all C mode's navigation functionality. But it colors according to the PHP grammar and indents according to the PEAR coding guidelines. It also includes a couple handy IDE-type features such as documentation search and a source and class browser.

Helm-SLY defines a few new commands:

• helm-sly-list-connections: Yet another Lisp connection list with Helm.

• helm-sly-apropos: Yet another apropos with Helm.

• helm-sly-mini: Like helm-sly-list-connections, but include an extra source of Lisp-related buffers, like the events buffer or the scratch buffer.

yaml-pro is a package that provides conveniences for editing yaml.

This package has been written to leverage tree-sitter parsing facilities, allowing all of these actions to be performed fast and accurate, even in the absence of parsing errors. The tree-sitter version is orders of magnitudes faster and I highly recommend its usage if your Emacs version permits.

This package contains a command to read Perl documentation in Emacs: M-x perl-doc. It uses two external commands which come with Perl: perldoc to locate the Perl documentation for the Perl modules installed on your system, and pod2html to format the documentation to HTML. This HTML version is then displayed using the Emacs simple HTML renderer, shr.

Emacsy is an embeddable Emacs-like library that uses GNU Guile as extension language. Emacsy can give a C program an Emacsy feel with keymaps, minibuffer, recordable macros, history, tab completion, major and minor modes, etc., and can also be used as a pure Guile library. It comes with a simple counter example using FreeGLUT and browser examples in C using Gtk+-3 and WebKitGtk.

This Emacs package provides the selected-minor-mode for Emacs. When selected-minor-mode is active, the keybindings in selected-keymap will be enabled when the region is active. This is useful for commands that operates on the region, which you only want bound to a key when the region is active. selected.el also provides selected-global-mode, if you want selected-minor-mode in every buffer.
