Guix

This is an inverse companion to the rx package for translating regexps in string form to the rx notation. Its chief uses are:

• Migrating existing code to rx form, for better readability and maintainability

• Understanding complex regexp strings and finding errors in them

In addition to Emacs regexps, this package can also parse and troubleshoot skip set strings, which are arguments to skip-chars-forward and skip-chars-backward.
