# procfile-nix
A library + [flake-parts](https://flake.parts/) module that helps you manage procfiles and background jobs with [overmind](https://github.com/DarthSim/overmind) (or any other Procfile runner)!
## Usage
Regardless of if you use the library or flakeModule, you will be putting a package into your development shells.
Following this, the name you gave the Procfile will be avalible as a command while will setup all of your processes.
Example:
```shell
$ nix develop
$ myprocfile
```
You can also send the command to run in the background like so: `myprocfile &`
## Usage (library)
First, put this in your `flake.nix`:
```nix
{
inputs = {
nixpkgs.url = "nixpkgs/nixpkgs-unstable";
procfile-nix = {
url = "github:getchoo/procfile-nix";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { nixpkgs, procfile-nix, ... }: let
systems = [ "x86_64-linux" "aarch64-linux" ];
forAllSystems = f: nixpkgs.lib.genAttrs systems (system: f nixpkgs.legacyPackages.${system});
in {
devShells = forAllSystems ({
lib,
pkgs,
system,
...
}: let
procfile = procfile-nix.lib.${system}.mkProcfileRunner {
name = "daemons";
procGroup = {
redis = lib.getExe' pkgs.redis "redis-server";
};
# OPTIONAL: switch the Procfile runner if desired.
procRunner = pkgs.honcho;
};
in {
default = pkgs.mkShell {
packages = [ procfile ];
};
});
};
}
```
Then run `nix develop`, `daemons &`, and you're good to go!
## Usage (flakeModule)
```nix
{
inputs = {
nixpkgs.url = "nixpkgs/nixpkgs-unstable";
flake-parts = {
url = "github:hercules-ci/flake-parts";
inputs.nixpkgs-lib.follows = "nixpkgs";
};
procfile-nix = {
url = "github:getchoo/procfile-nix";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = inputs:
inputs.flake-parts.lib.mkFlake { inherit inputs; } {
systems = [ "x86_64-linux" "aarch64-linux" ];
imports = [ inputs.procfile-nix.flakeModule ];
perSystem = {
config,
lib,
pkgs,
...
}: {
procfiles.daemons = {
processes = {
redis = lib.getExe' pkgs.redis "redis-server";
};
# OPTIONAL: switch the Procfile runner if desired.
procRunner = pkgs.honcho;
};
devShells.default = pkgs.mkShell {
packages = [ config.procfiles.daemons.package ];
};
};
};
}
```
Similar to the last example, `nix develop` and `daemons &` may be run to start your Procfile
