Path::Class::Rule - Iterative, recursive file finder with Path::Class
version 0.018
use Path::Class::Rule; my $rule = Path::Class::Rule->new; # match anything $rule->file->size(">10k"); # add/chain rules # iterator interface my $next = $rule->iter( @dirs ); while ( my $file = $next->() ) { ... } # list interface for my $file ( $rule->all( @dirs ) ) { ... }
This module iterates over files and directories to identify ones matching a user-defined set of rules.
As of version 0.016, this is now a thin subclass of Path::Iterator::Rule that operates on and returns Path::Class objects instead of bare file paths.
See that module for details on features and usage.
See "PERFORMANCE" for important caveats. You might want to use Path::Iterator::Rule instead.
Path::Iterator::Rule
This module may be extended in the same way as Path::Iterator::Rule, but test subroutines receive Path::Class objects instead of strings.
Path::Class
Consider whether you should extend Path::Iterator::Rule or Path::Class::Rule. Extending this module specifically is recommended if your tests rely on having a Path::Class object.
Path::Class::Rule
If you run with lexical warnings enabled, Path::Iterator::Rule will issue warnings in certain circumstances (such as a read-only directory that must be skipped). To disable these categories, put the following statement at the correct scope:
no warnings 'Path::Iterator::Rule';
Because all files and directories as processed as Path::Class objects, using this module is significantly slower than Path::Iterator::Rule.
If you are scanning tens of thousands of files and speed is a concern, you might be better off using that instead and only creating objects from results.
use Path::Class; use Path::Iterator::Rule; my $rule = Path::Iterator::Rule->new->file->size(">10k"); my $next = $rule->iter( @dirs ); while ( my $file = file($next->()) ) { ... }
Generally, I recommend use this module only if you need to write custom rules that need Path::Class features.
