## `commit-lint`

Lints the commit message header against
`<keyword>[<modifier>][(<scope>)][<reason>]: <description>`,
e.g. `add(exe)[int]: initial commit linting`.

### Install

```sh
cargo install --path crates/atypical-commit
```

### Usage

Pass a commit message file, or `-` to read from stdin:

```sh
commit-lint -- .git/COMMIT_EDITMSG
echo 'add(lib)[int]: something' | commit-lint -
```

Exit codes: `0` valid, `1` failed linting (or unreadable input),
`2` usage error or nothing to lint.

### Configuration

Every part of the syntax comes from the `[commit]` section of the
nearest `atypical.toml`, found from the working directory upward
(or passed with `--config <FILE>`). If no config is found, or keys are
omitted, the standard preset is used (shown here in full):

```toml
[commit]
keywords = ["add", "rem", "ref", "fix", "undo", "release"]
modifiers = ["?", "!", "!!"]
separator = ":"
modifier-sequence = "pre" # before the enclosures, or "post"

# Scopes; omit `allowed` to accept anything between the delimiters.
[[commit.enclosures]]
delimiters = ["(", ")"]
allowed = ["exe", "lib", "test", "build", "doc", "ci", "cd"]

# Reasons.
[[commit.enclosures]]
delimiters = ["[", "]"]
allowed = [
  "int", "pre", "eff", "rel", "cmp", "mnt", "tmp",
  "exp", "sec", "upg", "ux", "pol", "sty",
]
```

### As a `commit-msg` hook

With [husky](https://typicode.github.io/husky/), in `.husky/commit-msg`:

```sh
commit-lint -- "$1"
```

Or as a plain git hook, in `.git/hooks/commit-msg` (mark it executable):

```sh
#!/bin/sh
commit-lint -- "$1"
```
