Help by KConfig expansion

[Ahmad Reza Cheraghi]

 Im all the time going through all the file in the
<KERNEL>/scripts/kconfig without any success. I dont
find any beginning and any end.
I want to expand the Kconfig by a new Attribute. The
property of the attribute is just to give out the
message that is written beside it, to a new component
of the struct menu or struct poperty.

e.g.

config BLA
bool "bla"
auto "blabla"

That what is written beside the "auto" should save in
the Component called char *auto in one of the above
mentioned struct. There must be some changes in the
file zconf.tab.c. Any Suggestion how to this??

You have to modify zconf.l/zconf.y for this and regenerate this file 
(check the Makefile). First you have to define the keywords in zconf.l
and then extend the parser in zconf.y to recognize them and add the data 
to the internal structures.

I tryed to do this. I saw how the attribute "comment"
is definded in the zconf.l and zconf.y, and definded
the the attribute "autorule" exactly the same way. But
it still don't work. Even though I changed the
zconf.tab.c_shipped as well but it still dont work. I
dont understand the switch-case for yyn(line 1274 in
zconf.tab.c_shipped). Why does a the function
"menu_add_prop(P_COMMENT...)" (line 1587) gets called
by the case 75? How do you declare such a case number?
e.g. case 100 should calle
"menu_add_prop(P_AUTORULE...)".
I seriously wouldn't take your time by asking that, if
I didn't tryed any thing out, what comes up in my
mind. I realy cant figure it out by myself. I send you
diff file(patch) of what I changed. To see me what I
did wrong and what I should do.

Your sincerly

You need to generate the source using bison.
You must understand that zconf.l is an input file for flex.
Likewise zconf.y is input for bison.

See scripts/kconfig/Makefile for how to generate the files.
