The regex function has been removed (not Deprecated) as regexr is in beta mode. This move breaks backward compatibility and thus a bump in major release to version 1.0.0. BUG FIXES NEW FEATURES MINOR FEATURES IMPROVEMENTS CHANGES regex function replaced with the subs function. This move is both semantic and pragmatic. The term "regular expression chunk" has been replaced with "sub-expressions". The subs function reflects the semantic change. Additionally, Richie Cotton's regex package (https://github.com/richierocks/regex), which is complementary to regexr, contains a regex function. regexr 0.0.3 - 0.0.4 NEW FEATURES as.regexr added to coerce a regular expression to a regexr class using the regular expression breakdown of http://rick.measham.id.au/paste/explain.pl. The get_construct function extracts a script to create a construct regex from regexr objects that were coerced using as.regexr. MINOR FEATURES set_comments, set_regex, and set_names added as a convenience functions to set elements of a regexr object and return the object. IMPROVEMENTS print.summary_regexr used message to print to the console which had the potential to not return the entire input. print.summary_regexr now uses cat rather than message. CHANGES The recommended structure for the construct code is no longer a separate line for each regular expression chunk's name, regex, and comment but name, regex, and comment all go on the same line. This makes the code less cluttered and easier to navigate, particularity if indentation is used to indicate nested grouping structures. Users may choose whatever configuration that suits their preference, however, examples will generally be shown via the new recommended, single line, structure.
