Devel::PerlySense::Plugin::Syntax::Moose - Plugin for parsing Moose syntax constructs


Parses Moose specific syntax, like the "extends" keyword.

Currently supported:

  • has - Attributes

    Treated as subs (getters/setters).

    Multiple attributes and overridden attributes are supported.

    Things like handles, clearer, and predicate aren't supported.

  • extends - Inheritance

    Single and multiple inheritance supported.

  • with - Roles

    Treated as base classes.


Broken Moose code, e.g. multiple extends are parsed incorrectly (the ISA isn't reset). But you shouldn't have broken Moose code should you?

Roles are treated like base classes, because that's the most similar Perl concept.

Some parts of the parsing is a bit sloppy and fragile, e.g. comments in lists may be picked up.


This plugin module is not yet it's own distribution, which it should be. It should have a base class inside the PerlySense distro to future proof both PerlySense's and the plugins' APIs against each other.

The plugins could have some kind of marker for when they should be run for a document. It could be a quick regex on the source or per line or something.

Reporting back to PerlySense isn't quite uniform yet in that most things are set in a hash ref, but sub location are set on the Meta object. That should be fixed.



parse($rhDataDocument, $oMeta, $oDocument, $oNode, $pkgNode, $row, $col, $packageCurrent)

Parse the Devel::PerlySense::Document and extract metadata. Fill appropriate data structures.


the key e.g. "Moose" for Plugin::Syntax::Moose, is for the plugin to manage. It's persistent during the complete parse of a document.

Return 1 or die on errors.
