Nix-Mode describes itself as: ================================= Major mode for editing .nix files ================================= More at https://elpa.nongnu.org/nongnu/nix-mode.html ## Summary: A major mode for editing Nix expressions (.nix files). See the Nix manual ## Recent NEWS: # Changelog ## 1.5.0 * Removed json-mode dependency, using js instead. * Compatibility with Emacs 28+. * Add nix-flake commands, based on magit-session. * Add nix-store-show-log command. * Other various fixes. ## 1.4.5 * Fixed completion support in nix-repl-mode for Nix 2. ## 1.4.4 ### Changes * Fix a bug causing Nix-based completions to throw an error ## 1.4.3 ### Changes * Better documentation for nix-prettify-mode * Fixes for nix-eshell.el * Use `NIX_GET_COMPLETIONS` if Nix 3.0 is installed * Add flake.nix ## 1.4.2 ### Changes * Fixed build scripts to work with newer org-mode. * Invoke smie indent function locally, instead of globally. * Indent correctly when encountering preceding angle bracket paths. * Require Emacs 25. * Add json-mode dependency. ## 1.4.1 ### Changes * Made smie-setup optional.

It is still enabled by default. * Tweaks to how smie works. ## 1.4.0 ### Changes * Introduced SMIE indentation mode. It is now the default. The old behavior can be restored by setting ‘nix-indent-function’ to indent-relative. * Added the ‘nix-indent-region’ function to indent blocks of Nix expressions. This can be used as a dumb formatter. * Better testing has been added to make sure we handle more cases of Nix indentation style. ## 1.3.0 * Added manual. * Create CHANGELOG.md ### New files * nix.el: customization settings for nix installation ## 1.2.1 ### Changes * fix byte-compile error ## 1.2.0 ### New files * nix-format.el: format Nix code using nixfmt * nix-mode-mmm.el: treate multiline strings as sh-script within nix-mode * nix-repl.el: run nix-repl within Emacs * nix-prettify-mode.el: shorten store paths to /nix/store/…-foo-0.1 * nix-shell.el: run nix-shell within Emacs * nix-company.el: complete Nix expressions through company ### Changes All of these reflect nix-mode.el and what's been changed from the original nix-mode.el. * add some simple tests for nix-mode * handle antiquotes within Nix expressions better * handle multiline string better * fixes some edge cases for ''${ (escaped antiquote) * indent Nix code based on Nix-specific rules (not just indent-relative) * enforce Nix spacing style rules in nix-mode (2 spaces, no tabs) ### Bug fixes This version fixes the following bugs in the original Nix version: * fixes the issue where /* by a multiline string is interpreted as a comment (NixOS/nix#662) * fixes antiquote highlighting within double quotes like x="${asdf}" (NixOS/nix#1055) * fixes an issue in org-mode fontification of nix files (NixOS/nix#1040) * Also, should these issues should be closable: NixOS/nix#1419, NixOS/nix#1086, NixOS/nix#1054 ## 1.0 Original nix-mode from [https://github.com/NixOS/nix/](https://github.com/NixOS/nix/).
