I have a custom "plugin" I use extensively for verilog development, and I have a few functions I obviously call using respective mapping.

For example:

function! FormatIoInstance() range

   silent! :'<,'>v/\/\//normal! I.
   silent! :'<,'>v/\/\//s/\s\+$//g
   silent! :'<,'>v/\/\//s/,$/( ),/g
   silent! :'<,'>v/\/\/\|,/normal! A( )
   silent! :'<,'>v/\/\//Tab /(/l0
   
endfunction

with the following mapping for insert and select mode

inoremap <buffer> <silent> <nowait> <M-8> <C-o>:call FormatIoInstance()<CR>
snoremap <buffer> <silent> <nowait> <M-8> <C-o>:call FormatIoInstance()<CR>

However, extending the mapping to visual mode does not work (nothing happens) in visual mode:

xnoremap <buffer> <silent> <nowait> <M-8> <C-o>:call FormatIoInstance()<CR>

So what am I missing?

  • Quoting from :help :v: Instead of the '/' which surrounds the {pattern}, you can use any other single byte character, but not an alphabetic character, '\', '"', '|' or '!'. This is useful if you want to include a '/' in the search pattern or replacement string.

  • @romainl, what else would you need? If you are not prone to help, do not reply. It's better.

    Well, your visual mode mapping, with which you are supposedly having trouble with. That would be a good start.

I wonder what "doesn't work" mean and what exactly your xnoremap mapping looks like?

Did you try

xnoremap <buffer> <silent> <nowait> <M-8> :call FormatIoInstance()<CR>

?

  • I have tried the version of @Maxim and it works fine on my end.

  • Doesn't work means it doesn't work.. The C-o was the problem.... Thanks.

    @xyx usually "doesn't work" is vague—does anything happen? Does nothing happen? Do you get a beep, flash, error message? Any of these are useful details beyond "didn't do what I expected."

  • Honestly, I though that the question was quiet clear since I posted the syntax for inoremap and snoremap. "extending the mapping to visual mode" simply means adding one line as, for example, vnoremap <buffer> <silent> <nowait> <M-8> <C-o>:call FormatIoInstance()<CR>. Is it really poorly intuitive ? "Doesn't work" means "nothing happens". If Vim shows up some message and in this case it is relatively easy to track the problem, or error would be reported here as well.

  • I believe Maxim wonders why you keep the <C-o> that probably only make sense when you are in insert mode. Did you already had the chance to test the solution he proposes? It seems to work fine for me.
