Dear Vimers,
How do I do something like the following:
"
if(defined(tags))
return "\<c-x>\<c-]>"
endif
"
The tags-variable is the one set by :set tags="./tags".
How do I get the above to work?
Many thanks in advance!
Asis
My Background is the following:
Programming in Ruby I am using ctags in order to get tag-based completion.
I want to configure the supertab-plugin to use also <C-x><C-]>
(tag-completion).
The manual states:
"
In addition to the default completion contexts, you can plug in your own
implementation by creating a globally accessible function that returns
the completion type to use (eg. "\<c-x>\<c-u>").
function MyTagContext()
if filereadable(expand('%:p:h') . '/tags')
return "\<c-x>\<c-]>"
endif
" no return will result in the evaluation of the next
" configured context
endfunction
let g:SuperTabCompletionContexts =
\ ['MyTagContext', 's:ContextText', 's:ContextDiscover']
"
I don't want to check, if the tags-file is readable, I want to check if the
variable is set, because the rails-plugin sets it to ./tmp/tags and in other
contexts it might be something else again..
