I’m creating my first vim function and can’t get the definition right. I have this code in the file ‘myfunc’:
function! UnderlineSingle ()
let myline = getline(line('.'))
let myline = repeat('-', strlen(myline))
append(line('.'), myline)
endfunction
yet when I try to source it with the command:
:source myfunc
I get this error message
E126: Missing :endfunction
After a bit of head-scratching, I found that the line with the append function was causing the problem and that I had to assign the result of the append function to a variable, like so:
let tmp = append...
Is there a way to just execute a function for its side-effect and ignore the return code or do I always have to do this kind of temporary assignment?
Answer: I just do:
call append...
