Regexp/OCaml: A syntax extension for regular expression match
Regexp/OCaml provides convenient syntax sugar for regular expression match for strings using PCRE/OCaml library. The features of this macro package are the following:
- Convenient syntax: similar to standard match-with expression
- Binding matching substrings to variables: no more $1, $2, …
- Automagical easy-to-use type-coercion: no flood of int_of_string etc.
- Support for optional-patterns: gives string option type etc.
- Default values for optional-patterns
- Named subpatterns (in Python- or Ruby 1.9-style syntax)
A regular expression which appears in the source file will be evaluated only once; it is pre-compiled before actual execution and then cached. The package contains a small macro, called “once”, makes any value to be evaluated only once.
