| # 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. |

| # Perl Hooks | ||
|
|
||
| > This file extends [common/hooks.md](../common/hooks.md) with Perl-specific content. | ||
|
|
||
| ## PostToolUse Hooks | ||
|
|
||
| Configure in `~/.claude/settings.json`: | ||
|
|
||
| - **perltidy**: Auto-format `.pl` and `.pm` files after edit | ||
| - **perlcritic**: Run lint check after editing `.pm` files | ||
|
|
||
| ## Warnings | ||
|
|
||
| - Warn about `print` in non-script `.pm` files — use `say` or a logging module (e.g., `Log::Any`) |

| # Perl Patterns | ||
|
|
||
| > This file extends [common/patterns.md](../common/patterns.md) with Perl-specific content. | ||
|
|
||
| ## Repository Pattern | ||
|
|
||
| Use **DBI** or **DBIx::Class** behind an interface: | ||
|
|
||
| ```perl | ||
| package MyApp::Repo::User; | ||
| use Moo; | ||
|
|
||
| has dbh => (is => 'ro', required => 1); | ||
|
|
||
| sub find_by_id ($self, $id) { | ||

| my $sth = $self->dbh->prepare('SELECT * FROM users WHERE id = ?'); | ||
| $sth->execute($id); | ||
| return $sth->fetchrow_hashref; | ||
| } | ||
| ``` | ||
|
|
||
| ## DTOs / Value Objects | ||
|
|
||
| Use **Moo** classes with **Types::Standard** (equivalent to Python dataclasses): | ||
|
|
||
| ```perl | ||
| package MyApp::DTO::User; | ||
| use Moo; | ||
| use Types::Standard qw(Str Int); | ||
|
|
||
| has name => (is => 'ro', isa => Str, required => 1); | ||
| has email => (is => 'ro', isa => Str, required => 1); | ||
| has age => (is => 'ro', isa => Int); | ||
| ``` | ||
|
|
||
| ## Resource Management | ||
|
|
||
| - Always use **three-arg open** with `autodie` | ||
| - Use **Path::Tiny** for file operations | ||
|
|
||
| ```perl | ||
| use autodie; | ||
| use Path::Tiny; | ||
|
|
||
| my $content = path('config.json')->slurp_utf8; | ||
| ``` | ||
|
|
||
| ## Module Interface | ||
|
|
||
| Use `Exporter 'import'` with `@EXPORT_OK` — never `@EXPORT`: | ||
|
|
||
| ```perl | ||
| use Exporter 'import'; | ||
| our @EXPORT_OK = qw(parse_config validate_input); | ||
| ``` | ||
|
|
||
| ## Dependency Management | ||
|
|
||
| Use **cpanfile** + **carton** for reproducible installs: | ||
|
|
||
| ```bash | ||
| carton install | ||
| carton exec prove -lr t/ | ||
| ``` | ||
|
