HB_RegExReplace()

Hi!

Harbour has almost all regular expression functions of xHarbour but I am missing HB_RegExReplace.
Is there a similar function in Harbour?

Best regards, Timm.

Hi,

hb_regexReplace is in xhb contrib.

Check it in the library list.

Regards, Fausto.

Hi!

Did not found that library. Is it not only part of xHarbour?

Best regards, Timm.

I guess is libxhb.a. Is a compatibility library for xHarbour.

BTW, here is the code. Just include it on any PRG file. I hope it works. At least it links :-)
