RDoc::CrossReference
frozen_string_literal: false
RDoc::CrossReference is a reusable way to create cross references for names.
Constants
- ALL_CROSSREF_REGEXP
Version of CROSSREF_REGEXP used when
--hyperlink-all
is specified.- CLASS_REGEXP_STR
Regular expression to match class references
-
There can be a ‘\’ in front of text to suppress the cross-reference
-
There can be a ‘::’ in front of class names to reference from the top-level namespace.
-
The method can be followed by parenthesis (not recommended)
-
- CROSSREF_REGEXP
Regular expressions matching text that should potentially have cross-reference links generated are passed to add_special. Note that these expressions are meant to pick up text for which cross-references have been suppressed, since the suppression characters are removed by the code that is triggered.
- METHOD_REGEXP_STR
Regular expression to match method references.
See CLASS_REGEXP_STR
