extras: add full file name along with base file name

[RobertCElliott]

For --extras=+f, add the full file name along with the base file name.

For example, this allows using vim's -t argument:
vim -t main/entry.c
rather than requiring the -t be dropped:
vim main/entry.c

You have opened and closed pull requests repeatedly. I wonder what happened to you.
Is this ready for reviewing and commenting?

BTW, I recommend you to make a topic branch for hacking ctags instead of committing to your master branch. See https://git-scm.com/book/en/v2/Git-Branching-Branching-Workflows for more details.

[RobertCElliott]

Sorry, it took a while to understand the self-tests kicked off by the pull request and get them to run locally (the simple-glide one still doesn't run). I'm more familiar with using git send-email to send patches rather than pushing to github.

[masatake]

Oh, I see.

[masatake]

Instead of changing the output of --extras=+f, I would like you to extend the output of --extras=+qf.
So the extended function aligns with the other functions of ctags.

In that case, you don't have to update the expected output of test cases. Instead, you have to add a simple test case verifying --extras=+qf output. Tmain the place to put your test case.

[masatake]

I think it is better to emit full filename only when --extras=+q is given.
So the comment will be :

/* add the full filename too if --extras=+q is given. */

[masatake]

The condition will be (if you follow my idea):

if (base != fileName && isXtagEnabled (XTAG_QUALIFIED_TAGS))

[masatake]

markTagExtraBit (&tag, XTAG_QUALIFIED_TAGS);

[masatake]

Keep the original document as is.
Instead, could you add "If --extras=+q is given, ..." ?

[RobertCElliott]

Another idea I had was to add all partial paths, e.g., a/b/c/main.c, b/c/main.c, and c/main.c (along with main.c). Thoughts?

I feel adding all partial paths to the output when --extras=+qf is too much, and is not suitable for q extra. If you want all partial paths, add a new extra for the purpose.

See xtagDefinitions in main/xtag.c and xtagType in main/xtag.h.
You can use an extra name from a command line like:

$ u-ctags --extras='+qf{aName}' input...

@masatake this PR seems like a blocker for 6.1: https://github.com/universal-ctags/ctags/milestone/8

Shall it be rescheduled for 6.2? :)

[masatake]

@catap I agree with you.
