# Nix development environments, for various languages

Those of us on NixOS never install language toolkits system-wide, unlike other distros.
Regrettably, many projects are not taking advantage of Nix for reproducible development environments. You should
make a big fuss about this in every open source project you are a part of and constantly evangelize about Nix.
Until Nix is universally adopted, this repository serves as a collection of flakes which provides compilers,
package managers, and basic development tools like LSPs for common languages. Simply clone this to a desired location,
then run:

```bash
nix develop <location-of-repo>#<language>

# example
nix develop ~/.devenvs#rustNightly

# provides rust-analyzer, rustc, cargo, and some others from nightly toolchain
```

## Automatic environment loading

For convenience, you can use [nix-direnv](https://github.com/nix-community/nix-direnv) to
automatically load these environments.

Simply add the following `.envrc` to the project directory:

```bash
# file: .envrc
use flake <path-to-this-repo>#<language>
```

Example:

```bash
use flake ~/.devenvs#go
```

If you don't want to commit these files, make sure to run the following:

```bash
# tell git to ignore these direnv files for this local repository
git update-index --skip-worktree .envrc .direnv
```
