[Ocamlnet-devel] Really PCRE regexp ?

[Pierre-Alexandre V. <ont...@gm...>]

Hello, I have a problem with a PCRE regexp using Netstring_pcre module :
My regexp ( "\s.*" ) works with perl :
perl -e ' $s = "5bcb43b5f2d12bfc39cdd4dc1a4c3757b3129bc0
/tmp/UserLs_j.ml"; $s=~s/\s.*//g; print $s;'
*i get : 5bcb43b5f2d12bfc39cdd4dc1a4c3757b3129bc0*

But if i try :
Netstring_pcre.global_replace (Netstring_pcre.regexp_string "\\s.*") ""
"5bcb43b5f2d12bfc39cdd4dc1a4c3757b3129bc0  /tmp/UserLs_j.ml";;
- : string = "5bcb43b5f2d12bfc39cdd4dc1a4c3757b3129bc0  /tmp/UserLs_j.ml"


Other problem :
Netstring_pcre.global_replace (Netstring_pcre.regexp_string
"^([a-f0-9]+)\\s.*") "\\1" "5bcb43b5f2d12bfc39cdd4dc1a4c3757b3129bc0
/tmp/UserLs_j.ml";;

Exception:

Failure "Pcre.replace: backreference denotes nonexistent subpattern".


Regards,

Pierre-Alexandre
