C Variant (keywords) - Indexing [message #229722]

Hi;

First where to post this..is this correct forum?

I am using c/C++ perspective for Keil C51 code. There are variants
in the code that cause functions to be missing in the outline view
and cannot be searched.

How do I modify the C/C++ (or whatever part of Eclipse) to accomodate
keyword variants in the C language (for embedded processors)?

I submitted a lengthy post two days ago with all the gory details but
it was never posted for some reason..(censorship maybe??)

This is my post to the newcomers forum which one fellow points me here.
But I have not had a response so I am adding this to make it more clear
what I am asking help for.

>>>>>>>>>PREV POST ON NEWCOMERS FORMUM>>>>>>>>>>>>>>>>>>>
I am programming for 8051 targets with Keil Compiler. So there are
a number of keywords that are not recognized and indexed by Eclipse.

I want to modify Eclipse so it understands the language variances and
indexes them so the outliner and call heirarchy function properly.

Let me state here, that what the indexer misses does not show up in the
outliner or call heirarchy. For example:

a function prototype for an ISR

void isr_interrupt0(void);

the corresponding function declaration for an ISR (this is KEIL C51!)

void isr_interrupt0(void) interrupt VECTOR12
{
}

So what is seen in the indexer is the prototype (I think because it passes
the ANSI C syntax and I am using a C/C++ perspective)...BUT the
declaration is not shown in the outline view because of the (I believe)
unrecognized keywords or formatting of the function declaration.

Where do I address this issue? Is this done by creating a perspective? Or
is there some underlying indexer stuff that I need to modify...I saw a
video
presentation on the CDT where the guys said the indexer is custom
built...I just dont have a good block diagram of how this all fits
together..Where do I find that?

Saw a post in one of the groups that recommended putting a conditional
define in some property page. Instead I put it in a header file like so
and made the keyword variants only defined properly for the embedded
compiler, made them generic for the gnu or cygwin tool chain and now the
code indexes and the call heirarchy view picks up the variants (because
they are now not variants.) the key was to know the define for the indexer
which was given in the post.

So this is a solution for my problem, hope it helps someone else.
