regex
A module for compiling a subset of regexes to Janet PEGs. All regex are considered to be anchored, and performance is not going to be competitive with a native regex engine.
Supported regex features:
- single bytes
- escape characters
-
+,*,?,. - Repetitions, e.g.
a{1},a{1,3}. Repetitions are eagerly evaluated. - Ranges, e.g.
[A-Za-z] - Character classes, inverted character classes, e.g.
[abc],[^abc] - Alteration (choice), except alteration is ordered, as in pegs -- e.g.
a|b|c - Captures using parentheses, e.g.
(abc) - Non-capture groups, e.g.
(?:abc)
Features found in other regex may never be added - for more complex usage, use Janet's native PEG library.

regex/compile function source
(compile pattern) Compile a subset of regex to a PEG if pattern is a string. If pattern is a PEG, will return the PEG as is.
regex/find-all function source
(find-all reg text &opt start) Similar to peg/find-all, but for regexes.
regex/replace function source
(replace reg rep text &opt start) Similar to peg/replace, but for regexes.
regex/replace-all function source
(replace-all reg rep text &opt start) Similar to peg/replace-all, but for regexes.
