Parsing c header file

Consider using existing parser generators and existing grammar. This may get you started: stackoverflow. I'm just trying to compare the contents of a header file with a spreadsheet which lists the functions including return type and parameters that should be present in that header file.

I cant seem to find any : — stackPusher. I'd expect at least C grammar to be available as sample somewhere Add a comment. Active Oldest Votes.

This can be fixed more like this Jazzthedog over 6 years ago. Thank you 01MDM! It worked fine. Now, I just have to unravel you regex to understand the "magic".. I just to figure out the regex stuff! The deciding factor between the two approaches would be the need for implementing pre- and or post- answer functioniality.

If each handler is atomic, a simple list of parsers will suffice. If handlers have to prepare for or postprocess each other's results then the linked-list method applies. In your case it looks like all of your code paths are mutually eclusive so I'd stick with the simpler list-of-handler's method.

From the looks of your code above this could also be implemented without classes by just creating a list of parsing functions.

However you'd then have to retype the signature check logic in all of the functions and if future requirements change to something where state was relevant, you'd have a harder time refactoring.

I am not what are you trying to do.

In most cases, where I had to take data out of the code, I have created a special table with the data and included it into the code. Add a comment. Active Oldest Votes. Martin York Martin York k 80 80 gold badges silver badges bronze badges.
