    Lux

    Lux

    The Lux Programming Language

    Lux is a new programming language in the making. It's meant to be a functional, statically-typed Lisp that will run on several platforms, such as the Java Virtual Machine and JavaScript, Python, Lua, or Ruby interpreters. Lux is in the beta stage. The JVM compiler is pretty stable and the standard library has grown to a respectable size. Also, new experimental support for JavaScript, Python, Lua, and Ruby has been added. Read carefully before using this project, as the license disallows commercial use, and has other conditions which may be undesirable for some. The language is mostly inspired by the following 3 languages. Clojure (syntax, overall look & feel), Haskell (functional programming), and Standard ML (module system). They are implemented as plain-old data-structures whose expressions get eval'ed by the compiler and integrated into the type-checker. The main difference between Lux & Standard ML is that Standard ML separates interfaces/signatures and implementations/structures.

    dumb-jump

    dumb-jump

    an Emacs "jump to definition" package for 50+ languages

    Dumb Jump is an Emacs "jump to definition" package with support for 50+ programming languages that favors "just working". This means minimal -- and ideally zero-configuration with absolutely no stored indexes (TAGS) or persistent background processes. Dumb Jump requires at least GNU Emacs 24.3. Dumb Jump uses The Silver Searcher ag, ripgrep rg, or grep to find potential definitions of a function or variable under point. It uses a set of regular expressions based on the file extension, or major-mode, of the current buffer. The matches are run through a shared set of heuristic methods to find the best candidate to jump to. If it can't decide it will present the user with a list in a pop-menu, helm, or ivy (see dumb-jump-selector). For the currently supported languages it seems to do a good job of finding what you want. If you find a case where it does not work as expected do not hesitate to open an issue. It can be slow if it needs to use grep and/or a project is large.

    Magit

    Magit

    A Git porcelain inside Emacs

    Magit is a complete text-based user interface to Git. It fills the glaring gap between the Git command-line interface and various GUIs, letting you perform trivial as well as elaborate version control tasks with just a couple of mnemonic key presses. Magit looks like a prettified version of what you get after running a few Git commands but in Magit every bit of visible information is also actionable to an extent that goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated. In the background Magit just runs Git commands and if you wish you can see what exactly is being run, making it possible for you to learn the git command-line by using Magit. Using Magit for a while will make you a more effective version control user. Magit supports and streamlines the use of Git features that most users and developers of other Git clients apparently thought could not be reasonably mapped to a non-command-line interface.

    GPTel

    GPTel

    A no-frills ChatGPT client for Emacs

    GPTel is a simple, no-frills ChatGPT client for Emacs. No external dependencies, only Emacs. Also, it’s async. Interact with ChatGPT from any buffer in Emacs. ChatGPT’s responses are in Markdown or Org markup (configurable). Supports conversations (not just one-off queries) and multiple independent sessions. You can go back and edit your previous prompts, or even ChatGPT’s previous responses when continuing a conversation. These will be fed back to ChatGPT. Run M-x gptel to start or switch to the ChatGPT buffer. It will ask you for the key if you skipped the previous step. Run it with a prefix-arg to start a new session. In the gptel buffer, send your prompt with M-x gptel-send, bound to C-c RET. Set chat parameters (GPT model, directives etc) for the session by calling gptel-send with a prefix argument.

    Evil Collection

    Evil Collection

    A set of keybindings for evil-mode

    This is a collection of Evil bindings for the parts of Emacs that Evil does not cover properly by default, such as help-mode, M-x calendar, Eshell and more. Reduce context switching: As soon as “moving around” gets hardwired to <hjkl>, it becomes frustratingly inefficient not to have it everywhere. Community work: setting up bindings is tremendous work and joining force can only save hours for all of Evil users out there. While not everyone may agree on the chosen bindings, it helps to have something to start with rather than nothing at all. In the end, users are free to override a subset of the proposed bindings to best fit their needs. Having all bindings defined in one place allows for enforcing consistency across special modes and coordinating the community work to define a reference implementation.

    Smartparens

    Smartparens

    Minor mode for Emacs that deals with parens pairs

    Smartparens is a minor mode for dealing with pairs in Emacs. We generally target GNU Emacs version 24.3 and newer, however, everything should work mostly fine on anything newer than version 24. You can install smartparens from MELPA. Once installed, enable the default configuration. You may want to try smartparens-strict-mode. This enforces that pairs are always balanced, so commands like kill-line keep your code well-formed. Inside Emacs, M-x sp-cheat-sheet will show you all the commands available, with examples. Smartparens has a default configuration that works well for most languages. For language-specific behaviour, smartparens has a separate smartparens-FOO.el file for every language and smartparens-config.el loads these automatically.

    telega.el

    telega.el

    GNU Emacs telegram client (unofficial)

    telega is a full-featured unofficial client for Telegram platform for GNU Emacs. telega is actively developed, for this reason, some features are not implemented, or they are present just as skeletons for future implementation. However, the core parts are mature enough so that it is possible to use telega on daily basis. telega depends on the visual-fill-column and rainbow-identifiers packages. This dependency automatically installs if you install telega from MELPA or GNU Guix. Otherwise, will you need to install these packages by hand? telega is built on top of the official library provided by Telegram TDLib. Most distributions do not provide this package in their repositories, in which case you will have to install it manually by following the instructions. GNU Guix, however, does have both telega and TDLib packaged. If you use GNU Guix you can skip directly to Installing from GNU Guix.

    CIDER

    CIDER

    The Clojure Interactive Development Environment that Rocks for Emacs

    CIDER extends Emacs with support for interactive programming in Clojure. The features are centered around cider-mode, an Emacs minor-mode that complements clojure-mode. While clojure-mode supports editing Clojure source files, cider-mode adds support for interacting with a running Clojure process for compilation, debugging, definition and documentation lookup, running tests, and so on. CIDER aims to provide an interactive development experience similar to the one you’d get when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with Geiser), and Smalltalk. Programmers are expected to program in a very dynamic and incremental manner, constantly re-evaluating existing Clojure definitions and adding new ones to their running applications. You never stop/start a Clojure application while using CIDER - you’re constantly interacting with it and changing it.

    Clojure Mode

    Clojure Mode

    Emacs support for the Clojure(Script) programming language

    clojure-mode is an Emacs major mode that provides font-lock (syntax highlighting), indentation, navigation and refactoring support for the Clojure(Script) programming language. MELPA Stable is the recommended repo as it has the latest stable version. MELPA has a development snapshot for users who don't mind (infrequent) breakage but don't want to run from a git checkout. Available on the major package.el community maintained repos, MELPA Stable and MELPA repos. All the major modes derive from clojure-mode and provide more or less the same functionality. Differences can be found mostly in the font-locking - e.g. ClojureScript has some built-in constructs that are not present in Clojure. The proper major mode is selected automatically based on the extension of the file you're editing. Having separate major modes gives you the flexibility to attach different hooks to them and to alter their behavior individually (e.g. add extra font-locking just to clojurescript-mode) .

    ELisp Tree-sitter

    ELisp Tree-sitter

    Tree-sitter bindings for Emacs Lisp

    tree-sitter is an Emacs binding for Tree-sitter, an incremental parsing system. It aims to be the foundation for a new breed of Emacs packages that understand code structurally. Faster, fine-grained code highlighting. More flexible code folding. Structural editing (like Paredit, or even better) for non-Lisp code. More informative indexing for imenu. The author of Tree-sitter articulated its merits a lot better in this Strange Loop talk. The minor mode tree-sitter-mode provides a buffer-local syntax tree, which is kept up-to-date with changes to the buffer’s text. Run M-x tree-sitter-hl-mode to replace the regex-based highlighting provided by font-lock-mode with tree-based syntax highlighting.

    Emacs Markdown Mode

    markdown-mode is a major mode for editing Markdown-formatted text. The latest stable version is markdown-mode 2.5, released on Feb 12, 2022. See the release notes for details. markdown-mode is free software, licensed under the GNU GPL, version 3 or later. The primary documentation for Markdown Mode is available below, and is generated from comments in the source code. For a more in-depth treatment, the Guide to Markdown Mode for Emacs covers Markdown syntax, advanced movement and editing in Emacs, extensions, configuration examples, tips and tricks, and a survey of other packages that work with Markdown Mode. Finally, Emacs is also a self-documenting editor. This means that the source code itself contains additional documentation: each function has its own docstring available via C-h f (describe-function), individual keybindings can be investigated with C-h k (describe-key), and a complete list of keybindings is available using C-h m (describe-mode).

    Flycheck

    On the fly syntax checking for GNU Emacs

    Flycheck is a modern on-the-fly syntax-checking extension for GNU Emacs, intended as replacement for the older Flymake extension which is part of GNU Emacs. For a detailed comparison to Flymake see Flycheck versus Flymake. It uses various syntax checking and linting tools to automatically check the contents of buffers while you type, and reports warnings and errors directly in the buffer, or in an optional error list. Out of the box Flycheck supports over 40 different programming languages with more than 80 different syntax-checking tools, and comes with a simple interface to define new syntax checkers. Many 3rd party extensions provide new syntax checkers and other features like alternative error displays or mode line indicators. Flycheck needs GNU Emacs 24.3+, and works best on Unix systems. Windows users, please be aware that Flycheck does not support Windows officially, although it should mostly work fine on Windows.

    Irony-Mode

    Irony-Mode

    A C/C++ minor mode for Emacs powered by libclang

    irony-mode is an Emacs minor-mode that aims at improving the editing experience for the C, C++ and Objective-C languages. It works by using a combination of an Emacs package and a C++ program (irony-server) exposing libclang. irony-server provides the libclang interface to irony-mode. It uses a simple protocol based on S-expression. This server, written in C++ and requires the specified packages to be installed on your system. Exactly one package manager should manage irony-mode. If using apt, but the MELPA package is desired, uninstall the version managed by apt; Likewise, installing from both MELPA and straight.el may result in a state that requires a manual workaround. The backports mechanism is the recommended and officially supported method of accessing newer versions than Debian stable provides. In order to work correctly, irony-mode needs to know the compile flags. irony-cdb aims to provide as automatic as possible compile flags discovery, with minimal user input.

    Ivy Swiper

    Ivy Swiper

    Generic completion frontend for Emacs, Swiper

    Ivy is an interactive interface for completion in Emacs. Emacs uses the completion mechanism in a variety of contexts: code, menus, commands, variables, functions, etc. Completion entails listing, sorting, filtering, previewing, and applying actions on selected items. When active, ivy-mode completes the selection process by narrowing available choices while previewing in the minibuffer. Selecting the final candidate is either through simple keyboard character inputs or through powerful regular expressions. Ivy is for quick and easy selection from a list. When Emacs prompts for a string from a list of several possible choices, Ivy springs into action to assist in narrowing and picking the right string from a vast number of choices.

    Ox-Hugo

    Ox-Hugo

    A carefully crafted Org exporter back-end for Hugo

    ox-hugo is an Org exporter backend that exports Org to Hugo-compatible Markdown (Blackfriday) and also generates the front-matter (in TOML or YAML format). The ox-hugo backend extends from a parent backend ox-blackfriday.el. The latter is the one that primarily does the Blackfriday-friendly Markdown content generation. The main job of ox-hugo is to generate the front-matter for each exported content file, and then append that generated Markdown to it. There are, though, few functions that ox-hugo.el overrides over those by ox-blackfriday.el. The preferred way to organize the posts is as Org subtrees (also the main reason to write this package, as nothing like that was out there) as it makes the meta-data management for Hugo front-matter pretty effortless. If you are a one Org-file per post type of person, that flow works too! Just note that in this flow many of those #+hugo_ properties need to be managed manually.
