Readable Regular Expressions
Description
An R framework for constructing and managing human readable regular
expressions. It aims to provide tools that enable the user to write
regular expressions in a way that is similar to the ways R code is written.
The tools allow the user to (1) write in smaller, modular, named,
sub-expressions, (2) write top to bottom, rather than a single string (3)
comment individual chunks, (4) indent expressions to clearly present regular
expression groups, (5) add vertical line spaces and R comments (i.e., #),
and (6) test the validity of the concatenated expression and the modular
sub-expressions.
