# Perl Coding Style
|
|
|
|
> This file extends [common/coding-style.md](../common/coding-style.md) with Perl-specific content.
|
|
|
|
## Standards
|
|
|
|
- Always `use v5.36` (enables `strict`, `warnings`, `say`, subroutine signatures)
|
|
- Use subroutine signatures — never unpack `@_` manually
|
|
- Prefer `say` over `print` with explicit newlines
|
|
|
|
## Immutability
|
|
|
|
- Use **Moo** with `is => 'ro'` and `Types::Standard` for all attributes
|
|
- Never use blessed hashrefs directly — always use Moo/Moose accessors
|
|
- **OO override note**: Moo `has` attributes with `builder` or `default` are acceptable for computed read-only values
|
|
|
|
## Formatting
|
|
|
|
Use **perltidy** with these settings:
|
|
|
|
```
|
|
-i=4 # 4-space indent
|
|
-l=100 # 100 char line length
|
|
-ce # cuddled else
|
|
-bar # opening brace always right
|
|
```
|
|
|
|
## Linting
|
|
|
|
Use **perlcritic** at severity 3 with themes: `core`, `pbp`, `security`.
|
|
|
|
```bash
|
|
perlcritic --severity 3 --theme 'core || pbp || security' lib/
|
|
```
|
|
|
|
## Reference
|
|
|
|
See skill: `perl-patterns` for comprehensive modern Perl idioms and best practices.
