# 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/
|
|
```
|
|
|
