history
Project history and usage
regldg is a C command-line program that generates all bounded strings matching its supported regular-expression grammar.
Project history
Patrick Cronin developed regldg as a regular-expression grammar-language dictionary generator. Its official site documents version 1.0.1 and explains the project's terminology and differences from Perl regular expressions.
Adoption history
The project is distributed as a compact C command-line program intended to be portable to systems with a C compiler.
How it is used
Give regldg a supported regular expression to enumerate matching strings. Options constrain output, including maximum word length; patterns may also be supplied through standard input with --file=-. Users should consult the official differences page because its expression language does not exactly match Perl's.
Why package nerds care
regldg reverses the usual regular-expression workflow: instead of testing whether input matches a pattern, it enumerates strings in the pattern's language. This makes it a niche but useful tool for test-data generation, dictionaries, and bounded exploration of patterns.
