Thanks for the code. I tried to replicate the problem but ctags is
not generating the same tags for me as it did for you.
I created a new directory for testing this and within that directory
created a subdirectory, subdir. I put your code into a file named
task.lua in subdir. In the top-level directory I executed
ctags -R .
Here is the resulting tags file.
!_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 /dhieb...@users.sourceforge.net/
!_TAG_PROGRAM_NAME Exuberant Ctags //
!_TAG_PROGRAM_URL http://ctags.sourceforge.net /official site/
!_TAG_PROGRAM_VERSION 5.7 //
Task:succeed subdir/task.lua /^ function Task:succeed()$/;" f
As you can see, it contains only one tag.
I opened a file in the top-level directory and added the line
Task:succeed
Typing ^] over "Task" resulted in
E426: tag not found: Task
and typing ^] over "succeed" resulted in
E426: tag not found: succeed
I then executed
:set iskeyword+=:
Typing ^] anywhere over "Task:succeed" then resulted in Vim jumping
to the top of that function.
[Time passes while I do other work and think some more.]
I just appended those lines from your tags file to mine and added
tabs between the fields. Typing ^] over "TaskHandler" or
"prizeTask" resulted in E426. Then I executed
:set iskeyword+=.
and tried again. This time I got this error:
E429: File ".\init\taskHandler.lua" does not exist
So I think that's the problem: you need to have . in your
'iskeyword' option for Lua files.
HTH,
Gary
