regexr: regexr: Tools for Human Readable Regular Expressions

In regexr: Readable Regular Expressions

Description

regexr is 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 sub-expressions

4. Indent expressions to represent regular expression groups

5. Add vertical line spaces and R comments (i.e., #)

6. Test the validity of the concatenated expression and the modular sub-expressions

This framework harnesses the power and flexibility of regular expressions but provides a structural frame that is more consistent with both code writing and natural language conventions.
