peter palm's suggestion is a bit more elegant -- here's what
i do:
nmap <silent> <F1> :call F1_formatter("70")<CR>
imap <silent> <F1> <C-O>:call F1_formatter("70")<CR>
nmap <S-F1> :call F1_toggle_width("70")<CR>
imap <S-F1> <C-O>:call F1_toggle_width("70")<CR>
function! F1_formatter(cp)
let s:save_tw = &tw
let &tw = a:cp
silent normal gq}
let &tw = s:save_tw
endfunction
function! F1_toggle_width(w)
if &tw == 0
let &tw = a:w
else
let &tw = 0
endif
set tw?
endfunction
then i can do things like this:
nnoremap <Leader>m :source /home/scott/.vim/mail.vim<CR>
where mail.vim contains:
" mail mode settings
setlocal tw=60
setlocal ft=mail
nmap <silent> <F1> :call F1_formatter("60")<CR>
imap <silent> <F1> <C-O>:call F1_formatter("60")<CR>
nmap <S-F1> :call F1_toggle_width("60")<CR>
imap <S-F1> <C-O>:call F1_toggle_width("60")<CR>
nmap <F8> :s/^/> /<CR>:silent noh<CR>j
imap <ESC><F8> :s/^/> /<CR>:noh<CR>ja
nmap <S-F8> 2xj
what this buys me is the ability to have different F1
formatters defined for different session types just by
remapping the F1 keys
in the most generic case, i have tw=0 as the default in my
.vimrc -- who wants spurious line breaks added to their
code, or whatever -- when i want to format, F1 formats for
me
to be honest i'm not sure i need the toggle_width function,
since the formatter functions set width anyway, but i found
it comforting to be able to set textwidth and toggle it
handily
anyway, i haven't used F1 for help in decades
