hi
is there a way to check if a guioption is set.
normally I would use somthing like:
if guioptions == m :set guioptions-=m<cr>:else<cr>:set
guioptions+=m<cr>:endif<cr>
but since guioptions is a sequence of options and not just a single
letter, this wont work.
So how do I check if it is set? I was looking for somthing like the ~=
in perl but didn't seem to find such a thing.
- The operators a =~ b (string a matches regexp b) and a !~ b (string a
doesn't match regexp b) seem to be what you want;
- To access an option as if it were a variable, prefix its name with &
To toggle flag m if guioptions:
if &guioptions =~ "m"
set guioptions-=m
else
set guioptions+=m
endif
In a mapping:
:map <F5> :if &go =~ "m" <Bar> set go-=m <Bar> else <Bar> set go+=m
<Bar> endif<CR>
(all on one line)
