Summary
Better support for nested and optional capture group
Details
This change introduces a
TreeRegexp
class, which returns matches as a tree ofGroup
, which match the nested structure of capture groups in the regular expression source. Non-capturing groups are excluded.Motivation and Context
The tree structure makes it possible to access match groups with more precision than with a flat structure, and this is needed in order to support (nested) capture groups in parameter types.
