Mozc
Mozc - a Japanese Input Method Editor designed for multi-platform
Mozc is an open source Japanese Input Method Editor (IME) developed by Google, designed to provide Japanese text input across multiple operating systems including Android, macOS, Windows, GNU/Linux, and Chromium OS. The project originated as a subset of Google Japanese Input, released publicly under the BSD 3-Clause license for community use and development. Mozc offers core IME functionality such as text conversion, prediction, and dictionary-based input, enabling users to efficiently type and edit Japanese text. While Mozc shares much of its codebase with Google’s internal IME, it operates as an independent open source project without official support, guarantees, or stable release cycles. Developers can build Mozc from source for their preferred platform, and the repository includes detailed build instructions for Android, Linux, macOS, and Windows environments. -

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
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. -

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. -

lispy
Short and sweet LISP editing
This package reimagines Paredit - a popular method to navigate and edit LISP code in Emacs. Most of more than 100 interactive commands that lispy provides are bound to a-z and A-Z in lispy-mode. The advantage of short bindings is that you are more likely to use them. As you use them more, you learn how to combine them, increasing your editing efficiency. To further facilitate building complex commands from smaller commands, lispy-mode binds digit-argument to 0-9. For example, you can mark the third element of the list with 3m. You can then mark third through fifth element (three total) with 2> or >>. You can then move the selection to the last three elements of the list with 99j. If you are currently using Paredit, note that lispy-mode and paredit-mode can actually coexist with very few conflicts, although there would be some redundancy. -

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.

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. -
