# ndbom: nix diff bill of materials
ndbom collects the sources of a given installable to compute
the source diff between two versions.
The goal is to show the list of every LOC added after running
`nix flake update`.
## Usage
Here are a few demos:
- Compare two versions:
```ShellSession
$ nix flake update
$ ndbom diff github:TristanCacqueray/nix-diff-bill-of-materials#devShell.x86_64-linux .#devShell.x86_64-linux
[+] Modified ansi-terminal: 0.11.5 -> 1.0.2

## Install
Install `ndbom` by running: `nix profile install github:TristanCacqueray/nix-diff-bill-of-materials`
## Roadmap
- [x] Show source diff.
- [ ] Filter the materials using custom exclude/include list, for example to focus on package registry like crates.io.
- [ ] Filter the diff, for example to highlight CHANGELOGs.
- [ ] Index the diff, for example in quickwit to show statistics like number of LOC added.
## Notes
Matching sources with their package name is surprisingly complicated, and this implementation may not work for every installables.
If you know a better way to do this, please let me know!
