# Perlcritic Processor
## Purpose
Analyzes Perl code using [Perl::Critic](https://metacpan.org/pod/Perl::Critic).
The Rust alternative is [iperlcritic](iperlcritic.md): PPI and the severity-5 policies, in-process, with perlcritic's violations and positions. Switching is `perlcritic` → `iperlcritic` in the stanza header; `.perlcriticrc` is read as before.
## How It Works
Discovers `.pl` and `.pm` files in the project (excluding common build tool
directories), runs `perlcritic` on each file, and records success in the cache.
A non-zero exit code from perlcritic fails the product.
This processor supports batch mode.
If a `.perlcriticrc` file exists, it is automatically added as an extra input so
that configuration changes trigger rebuilds.
## Source Files
- Input: `**/*.pl`, `**/*.pm`
- Output: none (checker)
## Configuration
```toml
[processor.checker.perlcritic]
args = []
dep_inputs = []
```
| `args` | string[] | `[]` | Extra arguments passed to perlcritic |
| `dep_inputs` | string[] | `[]` | Extra files whose changes trigger rebuilds |
## Batch support
The tool accepts multiple files on the command line. When batching is enabled (default), rsconstruct passes all files in a single invocation for better performance.
## Clean behavior
This processor is a Checker — `rsconstruct clean outputs` is a no-op for it (checkers produce no outputs). See [Clean behavior](../../processors.md#clean-behavior) and [`rsconstruct clean`](../../commands.md#rsconstruct-clean).
