Re: [cdt-dev] Programmatically update macros in a header file
Well, we're certainly open to contributions to the rewriter.

Using CRefactoring class isn't applicable to my situation because I will provide my own view. So I tried using the ASTRewrite class but it does not seem to support rewriting macros in a header file. I get an exception: "Rewriting preprocessor statements is not yet supported". Can anyone confirm this. Thanks.

I resulted to manually rewriting the header file with the macros enumerated. However, this method does not preserve the tab spacing for the macros and the code comments.

Regards,
Richmond

That's a good question. I guess it should do both and we have a toggle that selects which system to use.

I just fear that the toggle will spread through a lot of code. For example, I've been looking at the refactorings we have. They'll all have to be totally redone which would mean each of the actions will have to look at the toggle to know what to do. How many other things do we have like that? Starting with a fresh new editor is a plan not to have to deal with that and just add features as they're ready.

Open to suggestions.

Hi,


I need to create a view where user can READ and UPDATE the macro values in
a header file of a C application.

Is there an efficient way for Eclipse CDT to programmatically READ and
MODIFY the macro definitions in a header file of a C application? How? Or
do I have to manually read, parse and update the file?

So far I am able to read macros in a file via IIndexManager
or ITranslationUnit. However, these options do not seem to provide a way to
update the macros.

Any help will be appreciated. Thank you.


Regards,
Richmond

One idea is to take a look at the Refactoring code. For example ExtractFunctionRefactoring. I?ve been using that as an example for a new editor I?m building which edits the code based on changes in the Properties View. Essentially you just need to create TextEdits and wrap them up in a Change object and the Refactoring engine takes care of the rest.

HTH,
Doug.
