Re: [FleXML-Users] your flexml change request

[William F. D. <wil...@th...>]

Hi Staffan,

I have checked in a change to flexml that should allow you to do what
you want (sourceforge bug #1526054).  Specify
   -h some_header.h
on the flexml command line, and the generated file will have
   #include "some_header.h"
at the bottom of the %{...%} section in the generated .l file.

For example, you can put into the .h file something like
#define YY_DECL \
   static int static_lexer_param; int lexer(int lexer_param)
#define YY_USER_INIT \
   static_lexer_param =3D lexer_param;

to change the name and signature of the generated scanner (and in this
case, have access in the action code to a parameter passed into the
lexer.)

You could also redefine YY_INPUT here.

Cheers,
Will
