[Gambas-user] gb.pcre: RegExp.Replace() problem

[Tobias Boege]

Hi,

attached is a script which essentially executes

  Print RegExp.Replace(" * * a *", "^[ ]*\\*", "'")

On my system the output is

  '' a *

which I don't understand. As the regular expression indicates I want only
the one match at the beginning of the line to be replaced. Not the second
one behind it. The "a" acts like a border, to see if the "^" is completely
ignored -- but it isn't.

The error seems to come from

--8<-- [ trunk/gb.pcre/src/regexp.c ]---------------------------------------
389                         r.subject = &subject[offset];
--8<------------------------------------------------------------------------

I guess that this should prevent recursive (indefinite) substitutions in the
replacement string... But if you ask me, the result of my script is wrong.

Regards,
Tobi
