  • 0

I am working with some code which has the following style:

int
add5 (int x) {
    return x+5;
}

In other words, the return value type of the function is written right above the function’s name. Because of that, ctags is not recognizing these functions and causing me a terrible headache. Does someone know how to get ctags to handle this case?

EDIT: ctags can recognize the function names on .c files but what I need is ctags to recognize the function names on .h files. On the .h files I have things such as:

int
add5 (int);

and there ctags does not recognize add5.

    You have to tell ctags to search for prototypes of functions. It is done with --<LANG>-kinds option.

    So, run following command:

    ctags --c-kinds=+p *

    And it will add the declaration to the tags file, as you can see in the output of my test:

    !_TAG_FILE_FORMAT       2       /extended format; --format=1 will not append ;" to lines/
!_TAG_FILE_SORTED       1       /0=unsorted, 1=sorted, 2=foldcase/
!_TAG_PROGRAM_AUTHOR    Darren Hiebert  /dhiebert@users.sourceforge.net/
!_TAG_PROGRAM_NAME      Exuberant Ctags //
!_TAG_PROGRAM_URL       http://ctags.sourceforge.net    /official site/
!_TAG_PROGRAM_VERSION   5.8     //
add5    add.h   /^add5 (int);$/;"       p
