* harbour/include/hbapi.h
+ added
void * pLex;
member to HB_MACRO structure - it will be necessary for MT safe
macro parser
* harbour/include/set.ch
* harbour/include/hbexprb.c
* harbour/source/macro/macro.l
* harbour/source/macro/macro.y
* indenting, formatting and converting tabs to spaces
* harbour/include/hbpp.h
* harbour/source/compiler/ppcomp.c
* harbour/source/pp/ppcore.c
* harbour/source/pp/ppgen.c
* harbour/source/pp/pplib.c
* make HB_PP_TOKEN structure public for other code and changed
public PP API to not force including static rules by programs
which does not need them.
+ added basic API for using PP as lexer
* divided HB_PP_TOKEN_MACRO to HB_PP_TOKEN_MACROVAR and
HB_PP_TOKEN_MACROTEXT and mark
[<keyword>][&<keyword>[.[<nextidchars>]]]+
as HB_PP_TOKEN_MACROTEXT not pair HB_PP_TOKEN_KEYWORD and
HB_PP_TOKEN_MACRO
It allows easier integration PP as (macro)compiler lexer and
fixes preprocessing [<keyword>][&<keyword>[.[<nextidchars>]]]+
in some patterns.
* harbour/utils/hbtest/Makefile
+ added PP library to linked library list
* harbour/source/macro/macro.y
+ added seaport to use PP as lexer. It's disabled by default and
can be enabled using by defining HB_PP_MACROLEX. It eliminates
using FLEX or SIMPLEX lexer in macro compiler. Now it emulates
the behavior of FLEX lexer because I wanted to minimize the
modification but in fact because parsed token are freed when
macro compiler finish its job then we can resolve RT memory
leaks which apear during parsing wrong expressions. It will be
enough to drop allocating memory for new terminal symbols and
using them as is like in compiler. It will also quite nice
simplify include/hbexpr*.c code and will allow to move some
functions to COMMON library. I want to make also pure compiler
code MT safe so I will have to add passing pointer to a structure
with compiler context just like in macro compiler. It means that
if we define a structure which will be common to compiler and macro
compiler with local (not common) data stored in other structure for
which will will keep only a pointer then we will be able to move most
of include/hbexpr*.c code to common library. But I do not want to
make farther modification without consultation without Ryszard.
Also to make PP default lexer some farther modifications should
be done in core PP code and include/hbexpr*.c files to not reduce
the speed. Now using HB_PP_MACROLEX for sure will have to cause
speed reduction in macro compiler. But if we make necessary
modifications then we should keep at least the same speed or
probably reach noticeable better results.
