# Development Guide

## Add new commands

1. Create a new config file in `share/` (e.g., `conf.mycommand`)
2. Add rules in the format:
   ```ini
   regexp=REGEX
   colours=COLOR1,COLOR2,...
   ```
3. Test with:
   ```bash
   echo "ERROR: Something went wrong" | cargo run --  -c conf.mycommand
   ```
4. Enable command in `src/rgrc.conf` to load the new config file. after that, the command will be available as `rgrc mycommand` (or via alias if configured).

## Testing

```bash
# Run tests
make test
# Run tests with coverage
make cov
```

## Code Formatting and Linting

```bash
make check
```

## Local Installation

```bash
make install

# Uninstall
make uninstall
```

## Advanced Features

### Count/Replace

```ini
# Match only once per line
regexp=^\s*#
colours=cyan
count=once

# Replace matched text (with backreferences)
regexp=(ERROR|WARN|INFO)
colours=red,yellow,green
replace=[\1]

# Stop processing after match
regexp=^FATAL
colours=red,bold
count=stop
```

**Count options**: `once`, `more` (default), `stop`
