# What's this?
Confwhich is an attempt to make working with `XDG_CONFIG_DIRS` and `XDG_CONFIG_HOME` easier by providing some nice utility functions.

# Useage
```
Usage: confwhich [OPTIONS] <SEARCH>

Arguments:
  <SEARCH>  The config prefix to search for

Options:
      --skip-home                    Skip directories in XDG_CONFIG_DIRS that start with the home directory
  -a, --all                          Print all matches in XDG_CONFIG_DIRS, not just the first
      --from-process <FROM_PROCESS>  Read the environment from a process by pid instead of regular environment [default: -1]
      --show-tilde                   Output a tilde for HOME directory
  -h, --help                         Print help
  -V, --version                      Print version
```

Confwhich allows reading `XDG_CONFIG_DIRS` and `XDG_CONFIG_HOME` from a running process by provided process id, assuming the `confwhich`process is elevated enough to read the environ file at `/proc/<pid>/environ`. Potential useage might be e.g. `confwhich --show-tilde --from-process $(pgrep alacritty | head -n 1) alacritty` which will return `~/.config/alacritty.toml` on my system.

# Installing
Any system that can build rust applications can have confwhich.

```bash
git clone https://git.grimmauld.de/Grimmauld/confwhich.git
cd confwhich
cargo build --release
```

Alternatively, this project supports nix tooling. The included flake provides a module installing `confwhich` to system packages, but also a default package for `nix run git+https://git.grimmauld.de/Grimmauld/confwhich`.
