ctags/vim - Trouble handling expressions with brackets in identifier list

Question

I'm using vim with ctags (exuberant 5.7) to navigate my source code. Some of the functions and variables have some Intel C extension keywords added to them however, namely:

__declspec(target(mic)) double calculate_gamma(int m, int n) { ... }

The problem is that because of the __declspec the ctags neglects to index it so the function calculate_gamma doesn't get tagged.

The fix to this sort of thing with ctags you use the identifier list option -I. However this options hates you if your expression has brackets in it:

$ ctags *.c *.h -I __declspec(target(mic))
-bash: syntax error near unexpected token `('

I've tried putting quotation marks around __declspec, escape characters '\', and ansi-C quoting $'' and these all stop bash from complaining, but then ctags still doesn't tag the function calculate_gamma. If the brackets weren't there this would work.

What am I doing wrong or is there another way to get what I want out of ctags? Cheers.

Answer 1

I think you want:

ctags -I __declspec+ *.c *.h

The -I __declspec essentially tells ctags to ignore __declspec as if it were a macro, and the + suffix means to also ignore the parenthesized arguments which follow __declspec.
