Harbour hb_compilebuf* function ...

[Rimantas]

Hi ,

Can't understand from C code what parameters are needfuls for this function . And what is the best way to run prgs as scripts ?

How about that : __HrbRun( hb_compileBuf( memoread( cDef_kl + cPrg + ".prg" ) ) ) ?

Another question - how to see what errors of source are in scripting prg ? I tried something like that :

Code: Select all  Expand view

   TRY

      __HrbRun( hb_compileBuf( memoread( cDef_kl + cPrg + ".prg" ) ) )

   CATCH e

      MsgInfo( "error ...)
      return( NIL )

   END

How to do own error analyzer ?

3-t question - can I get an return of scripting prg object ? In most situations it's needfuls to know windows handle number . So I'm doing in prg's script - define window ... activate window... and then return( oWnd:hWnd ) . But I don't know how get if from __HrbRun( ) . It's possible ?

Many thanks in advance ! With best regards !

Rimantas,

This way you redirect the compiler output to a file. Later you have to analyze the output file yourself for errors:

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()
 
   FReOpen_Stderr( "comp.log", "w" )
   HB_compilebuf( HB_ARGV( 0 ), "test.prg" )
   MsgInfo( MemoRead( "comp.log" ) )

return nil

#pragma BEGINDUMP

#include <stdio.h>
#include <hbapi.h>

HB_FUNC( FREOPEN_STDERR )
{
   hb_retnl( ( LONG ) freopen( hb_parc( 1 ), hb_parc( 2 ), stderr ) );
}    

#pragma ENDDUMP

function Main()
 
   FReOpen_Stderr( "comp.log", "w" )
   HB_compilebuf( HB_ARGV( 0 ), "test.prg" )
   MsgInfo( MemoRead( "comp.log" ) )

return nil

Many thanks fro your sample ! It's working fine . But ... Antonio , with all prgs I'm getting that are errors - No code gereated ... . Maybe it's needful to pass more parameters ? Libs , includes paths ?

Regards !

Rimantas,

You have to specify the compiler parameters this way:

Code: Select all  Expand view

HB_compilebuf( HB_ARGV( 0 ), "test.prg", "-n", "-Ic:\fwh\include" )

Many thanks , Antonio ! It's working fine !

Antonio , I did something like that :

Code: Select all  Expand view

METHOD RunScrpt( cPrg, cParams, nWd ) CLASS TApplic
local lRet := .t.
local oRun
local cTxtFile, cLine, nFrom := 1
local cPrgs := "Prgs\"
if File( cPrgs + cPrg + ".prg" )
   TRY
      if File( "comp.log" )
         ferase( "comp.log" )
      endif
      FReOpen_Stderr( "comp.log", "w" )
      oRun := HB_compilebuf( HB_ARGV( 0 ), cPrgs + cPrg + ".prg", "-n", "-Ihrb_incl;fwh_incl" )
      cTxtFile = MemoRead( "comp.log" )
      while nFrom < Len( cTxtFile )
         cLine = ExtractLine( cTxtFile, @nFrom )
         SysRefresh()
         if Upper( StrToken( cLine, 2 ) ) == "ERROR"
            lRet := .f.
            exit
         endif
      enddo
      if !lRet
         MsgInfo( MemoRead( "comp.log" ) )
        else
         hb_HrbRun( oRun )
      endif
   CATCH e
     lRet := .f.
   END
  else
   MsgInf(  "Can't to find file - " + cPrg + ".prg ...", 2 )
   lRet := .f.
endif
return( lRet )

It's working very fine . It's wanting very little ... . How to pass needful parameter to my script ? At first I did Hb_HrbRun( oRun, cParams ) . But parameter didn't apears in script . And maybe it's possibility to get return parameter from script ? If exist such possibilities ( to pass parameter and get return parameter ) - then my ERP will be the best ...

With best regards !

Rimantas,

Try to create a public variable from your script and save inside it the result. The public variable should remain alive after the script runs:

Code: Select all  Expand view

public MyReturn

MyReturn := 123 // MyCode()
