Install for Emacs with Nix

Supported operating systems:

Install prerequisites

In order to install quick-lint-js' Nix package, you must first install Nix or NixOS.

Install one of the following Emacs plugins:

Install quick-lint-js

Open a terminal, and run the following command:

nix-env -iA nixpkgs.quick-lint-js

If the above command fails with “error: attribute 'quick-lint-js' in selection path 'nixpkgs.quick-lint-js' not found”, your Nixpkgs is out of date. Either update Nixpkgs, or install from quick-lint-js' repository instead:

nix-env -f https://c.quick-lint-js.com/releases/2.5.0/source/quick-lint-js-2.5.0.tar.gz -iA quick-lint-js

Install Emacs plugin

  1. Download the quick-lint-js Emacs plugin.
  2. Extract quick-lint-js-emacs.zip's files into a directory somewhere safe (for example, ~/.emacs/quick-lint-js-emacs/).
  3. Add the quick-lint-js-emacs directory to the Emacs load-path variable. For example, add the following line to your init file (e.g. ~/.emacs):
    (add-to-list 'load-path "~/.emacs/quick-lint-js-emacs")
  4. Restart Emacs.
