# Nix Attr Search
|
||||
|
||||
**NOTE: This is still in alpha**
|
||||
|
||||
These are some tools i made for ease of searching for stuff while writing my nix configs.
|
||||
|
||||
They are made with `fzf`, so they can easily be piped into other programs.
|
||||
|
||||
Also, they all create a derivation containing all of the attributes.
|
||||
|
||||
---
|
||||
|
||||
## Try it out!
|
||||
|
||||
### Nix Packages
|
||||
|
||||
TODO:
|
||||
|
||||
### Nix Options
|
||||
|
||||
TODO:
|
||||
|
||||
### Homemanager
|
||||
|
||||
```
|
||||
nix run github:h7x4/nix-attr-search#home-manager-search
|
||||
```
|
||||
|
||||
Or a more advanced version:
|
||||
|
||||
```
|
||||
nix run github:h7x4/nix-attr-search#home-manager-search -- --flake="github:nix-community/home-manager" --ref="release-22.05"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Some piping ideas
|
||||
|
||||
### Misc
|
||||
|
||||
- Pipe the option into the clipboard
|
||||
- Bind shortcut keys to open a terminal with the program, and paste the chosen option directly into the current program (probably a code editor of some sort, with your nix configs open).
|
||||
|
||||
### Repiping values into `jq`
|
||||
- Repipe the chosen value into `jq`, and choose either the default value, the example value.
|
||||
- Repipe the chosen value into `jq`, choosing its referenced configs, pipe these into `fzf` once more to choose one referenced config, then pipe this relative file path into `rg` to (hopefully) find the specific location the value was set, and then open the file at its specific position in an editor.
