[Caml-list] Does any current ocaml program understand the {n1,n2} regexp syntax?

[Caml-list] Does any current ocaml program understand the {n1,n2} regexp syntax?

[Stalkern 2]

Hello to everybody

I went and used Str.regexp, but it seems that it does not use things like the 
{ } notation, i.e. {<minimum number of occurrences>, <maximum number of 
occurrences>}


        # Str.string_match (Str.regexp "y{3,}") "yyy" 0;;
        - : bool = false

What should I use then? PCRE, Vouillon's RE (BTW, where can I find this), 
anything else?

Thank you
Ernesto

See http://caml.inria.fr/ocaml/htmlman/libref/Str.html.

The syntax for regular expressions is the same as in Gnu Emacs.

I found pcre-ocaml by Markus Mottl however you say it is unsafe :)
Mmm, I have no idea.
