# Linting rules for Spicy
This repository contains a [Spicy](https://docs.zeek.org/projects/spicy/en/latest/)
integration for [ast-grep(sg)](https://ast-grep.github.io/) and a collection of
linting rules.
## Quickstart
Building this package requires Node. To build ast-grep support for Spicy run
```console
npm install
```
With that you can run the bundled linting rules with
```console
# Check all files in directory.
./spicy-lint .
# Check given file(s).
./spicy-lint foo.spicy
```
```ruby
module foo;
type X = unit {
: b"HELLO";
x: uint8 { print self.x; }
};
```
```console
$ spicy-lint foo.spicy
note[print-in-prod]: print in non-debug code found
┌─ foo.spicy:5:16
│
5 │ x: uint8 { print self.x; }
│ -----------^^^^^----------
│
= Usually 'print' statements are used for debugging. Adding them in production
code can introduce overhead, so it is best to either remove them, or move
them to hooks marked '%debug'.

note[use-skip]: use 'skip' for anonymous field

Note:
If a field is anonymous and not accessed via '$$' it can be declared 'skip'
so it is not stored.

note[use-dd]: use $$ instead of field access

6 6│ };
Note:
Use '$$' to refer to a field in its hooks. This is more compact and requires
less changes if the field gets renamed.
```
## Advanced usage
The linter script `spicy-lint` is a thin convenience wrapper around
[ast-grep(sg)](https://ast-grep.github.io/) which sets up an enviroment to run
the linting rules in this repo, but with the Spicy integration in
`sgconfig.yml` one has access to all ast-grep(sg) features, e.g., to run queries on code with `sg run`:
```console
# To use the sg binary bundled in this package.
$ npm exec -- sg run -p 'foo' foo.spicy
foo.spicy:1:module foo;
# To use a `sg` binary from your system.
$ sg run -p 'foo' foo.spicy
foo.spicy:1:module foo;
```
See the [ast-grep(sg) tooling
documentation](https://ast-grep.github.io/guide/tooling-overview.html) for an
overview.
