Nix IDE installs statistics

Nix ✨💡🌟

Adds Nix language support for Visual Studio Code.

Quickstart 🚀

1. Install the extension, and open a Nix file. 1. Syntax highlighting should work out of the box. Nix code blocks inside markdown files are also supported. 1. Auto-formatting should work if nixfmt is available in $PATH. A custom formatter can be set by configuring nix.formatterPath. 1. Syntax errors are linted using nix-instantiate. 1. Full language support can be enabled by configuring a language server. See LSP Plugin Support for more information. 1. Snippets are provided for conditional expressions, let/with expressions, and recursive sets. 1. Path completion is supported using the Path Intellisense extension.

Settings ⚙️

LSP Plugin Support

Full language support can be enabled by using a language server. Generally, any Nix LSP implementation should work. Some examples are given below for nil and nixd.

Home Manager integrated as a NixOS module

When Home Manager is integrated into a NixOS configuration, its options are stored under that configuration instead of homeConfigurations. Configure the home-manager option set like this:

Replace with the key of the matching nixosConfigurations entry.

Custom Formatter

It can be changed by setting nix.formatterPath to any command which can accept file contents on stdin and return formatted text on stdout.

[!IMPORTANT] If you are using the above LSP plugin setting, then this configuration is not used.
