Description-en: convert string regexp to rx notation
XR converts Emacs regular expressions to the structured rx form, thus
being an inverse of rx. It can also find mistakes and questionable
constructs inside regexp strings.
.
It can be useful for:
.
* Migrating existing code to rx form
* Understanding what a regexp string really means
* Finding errors in regexp strings
.
It can also parse and find mistakes in skip-sets, the regexp-like
arguments to skip-chars-forward and skip-chars-backward.
