My regex fails under Harbour
Posted: Fri Nov 04, 2022 10:21 AM

Any idea why I get .f. for all of these under Harbour?

#include "fivewin.ch"
proc main()
? hb_isregex("\d")
? hb_isregex("\d+")
? hb_isregex("[0-9]")
return

Code (fw): Select all Collapse
#include "fivewin.ch"
proc main()
? hb_isregex("\d")
? hb_isregex("\d+")
? hb_isregex("[0-9]")
return

Please, try

Code (fw): Select all Collapse

#include "fivewin.ch"
proc main

   local pRegx
   pRegx := HB_RegExComp( "\d" )
   ? hb_isregex( pRegx )
   //
return

HB_IsRegEx( <uExp> ) → <lIsCompRegEx>
Tells if <uExp> is a compiled regular expression compiled with HB_RegExComp()

Thanks Cristobal.

The sentence now works in my standalone test but not my module.

Is there anyway to check where the linker is pulling hb_regex() from? It seems suspicious that I get an empty array when there is no match instead of NIL

Thanks Cristobal.
If under Harbour hb_regex() returns an empty array when no match is found then it is different from xHarbour. From xHarbour Language Reference Guide 1.1

Return
The function returns an array filled with the found substrings matching the regular expression. If no match is found, the return value is NIL.

Thanks for pointing that out.

Just an update. The problematic regex problem went away when I rearranged libs (the bold part) to be linked from

j:\harbour\bcc7\lib\cw32.lib +
j:\harbour\bcc7\lib\import32.lib +
j:\harbour\bcc7\lib\uuid.lib +
j:\harbour\bcc7\lib\ws2_32.lib +
j:\harbour\hbcc7\lib\win\bcc\hbcpage.lib +
j:\harbour\hbcc7\lib\win\bcc\hbcplr.lib +
j:\harbour\hbbc7\lib\win\bcc\hbct.lib +
j:\harbour\hbbc7\lib\win\bcc\hbpcre.lib +
j:\harbour\hbbc7\lib\win\bcc\hbnf.lib +
j:\harbour\hbbc7\lib\win\bcc\xhb.lib +
j:\harbour\hbbc7\lib\win\bcc\hbziparc.lib +
j:\harbour\hbbc7\lib\win\bcc\hbmzip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbzlib.lib +
j:\harbour\hbbc7\lib\win\bcc\minizip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbusrrdd.lib +
j:\harbour\hbbc7\lib\win\bcc\hbtip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbzebra.lib +
j:\harbour\bcc7\lib\psdk\odbc32.lib +

to

j:\harbour\hbcc7\lib\win\bcc\hbcpage.lib+
j:\harbour\hbcc7\lib\win\bcc\hbcplr.lib+
j:\harbour\hbbc7\lib\win\bcc\hbct.lib +
j:\harbour\hbbc7\lib\win\bcc\hbpcre.lib +
j:\harbour\hbbc7\lib\win\bcc\hbnf.lib +
j:\harbour\hbbc7\lib\win\bcc\xhb.lib +
j:\harbour\hbbc7\lib\win\bcc\hbziparc.lib +
j:\harbour\hbbc7\lib\win\bcc\hbmzip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbzlib.lib +
j:\harbour\hbbc7\lib\win\bcc\minizip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbusrrdd.lib +
j:\harbour\hbbc7\lib\win\bcc\hbtip.lib +
j:\harbour\hbbc7\lib\win\bcc\hbzebra.lib +
j:\harbour\bcc7\lib\cw32.lib +
j:\harbour\bcc7\lib\import32.lib +
j:\harbour\bcc7\lib\uuid.lib +
j:\harbour\bcc7\lib\ws2_32.lib +
j:\harbour\bcc7\lib\psdk\odbc32.lib +

Now I'm only left with the perplexing issue of the linker not finding hbcpage.lib and hbcplr.lib even though in the link script the full path was written and I checked to make sure they exist. For the time being I'm forced to copy both of the libs into where my source is
