## statix
2021-10-02 08:22:22 +03:00
`statix` intends to be a static analysis tool for the
Nix programming language.
2021-10-02 08:22:22 +03:00
For the time-being, `statix` works only with ASTs
produced by the `rnix-parser` crate and does not evaluate
2021-10-02 08:22:22 +03:00
any nix code (imports, attr sets etc.).
## Architecture
2021-10-02 08:22:22 +03:00
`statix` has the following components:
- `bin`: the CLI/entrypoint
- `lib`: library of lints and utilities to define these
lints
- `macros`: procedural macros to help define a lint
### `bin`
2021-10-02 08:22:22 +03:00
This is the main point of interaction between `statix`
and the end user. It's output is human-readable and should
also support JSON/errorfmt outputs for external tools to
use.
### `lib`
A library of AST-based lints and utilities to help write
those lints. It should be easy for newcomers to write lints
without being familiar with the rest of the codebase.
### `macros`
This crate intends to be a helper layer to declare lints and
their metadata.
