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

see :help exists()
if !exists('+tags') || &tags == ""
" ! logical NOT
" exists('+tags') compiled-in and works
" || logical OR
" &tags the value of the 'tags' option
" == "" is set to the empty string
" meaning: «if empty or not compiled-in»
" -- we test first for compiled-in

" NOTE: the empty string is NOT the default value
" of the 'tags' option
endif
if exists('foobar')
echo 'foobar is defined as' foobar
else
echo 'foobar is undefined'
endif
if exists(':MySpecialCommand') == 2
echo ':MySpecialCommand is defined, as follows:'
verbose command MySpecialCommand
else
echo ':MySpecialCommand is undefined'
endif
if exists('*MySpecialFunc')
echo 'MySpecialFunc() is defined, as follows:'
verbose func MySpecialFunc
else
echo 'MySpecialFunc() is undefined'
endif
etc.
Best regards,
Tony.
