Problem with Harbour Core ( RegEx)

Problem with Harbour Core ( RegEx)

Postby Silvio.Falconi » Thu Dec 14, 2017 3:05 pm

if I try
? HB_RegExHas( "a", "aaa" )
? HB_RegExHas( "a", "AAA" )
? HB_RegExHas( "a", "AAA", .F. )

give me allways FALSE

instead the values must be true false true

i saw it on a guide oh harbour / core

why there is this error ?????

with Embarcadero is different ?

I have this compiler version : Compiler version: Harbour 3.2.0dev (r1703231115)
Since from 1991/1992 ( fw for clipper Rel. 14.4 - Momos)
I use : FiveWin for Harbour November 2023 - January 2024 - Harbour 3.2.0dev (harbour_bcc770_32_20240309) - Bcc7.70 - xMate ver. 1.15.3 - PellesC - mail: silvio[dot]falconi[at]gmail[dot]com

There is no HB_REGEXHAS() function in xHarbour.

I do not think it's correct item,

in regex \S it does not mean anything,

it should be interpreted as S, I wanted to \bS where \b means "word limiter" practically the regex "Silvio"

also finds Silvio inside the word "faSilvioooo"

(at random) while the regex ""\bSilvio\b" finds only Silvio if it is a unique word.

and However if this were the problem the 3rd case, which is correctly written, would work ...

I think the problem is that in harbor the libraries are looked for when compiling the compiler not in the process of compiling the single program ...
