I remember that library. A year after I made regexpbuilder https://www.npmjs.com/package/regexpbuilder that library suddenly appeared, and was basically a rip-off of the concept I appear to have created (there was no such other library before regexpbuilder), but is also fairly useless because it doesn't look like it could represent more than about 10% of the possible regular expressions. Yet there was no mention of my library at all in the readme of verbal expressions.
