Hi,
I have certain scripts in my plugin directory. And for them I have
several mappings. Nothing special. But now I want to merge two
mappings into one.
In script 1 I have a mapping <leader>f
"{{{ mappings and default options
if !hasmapto("<Plug>SimpleFold_Foldsearch")
map <unique> <silent> <Leader>f <Plug>SimpleFold_Foldsearch
endif
noremap <unique> <script> <Plug>SimpleFold_Foldsearch <SID>FoldSearch
noremap <SID>FoldSearch :call <SID>Foldsearch("")<cr>
In script 2 I have a mapping <C-space>
nnoremap <C-space> :call ToggleFold()<CR>
inoremap <C-space> <C-O>:call ToggleFold()<CR>
I want to updated the <C-space> mapping that it does first the
<leader>f function and then the orignal function after.
But then I write this as the mapping
nnoremap <C-space> <Leader>f :call ToggleFold()<CR>
inoremap <C-space> <C-O> <Leader>f :call ToggleFold()<CR>
Nothing happens.
Question 1: Can a nnoremap and and inoremap be combined?
Question 2: Is the leader mapping causing the problem? If not what
else might be the problem?
Alternative I can merge the scripts, but I prefer to keep them
seperated.
Issue 1:
:nnoremap <C-Space> <Leader>f... prevents remapping of <Leader>f,
use :nmap instead.
Issue 2:
on the right hand side, each character has a meaning (including white
space)
:nmap <C-space> <Leader>f :call ToggleFold()<CR>
-------------------------^
instead you want
:nmap <C-space> <Leader>f:call ToggleFold()<CR>
Issue 3:
<C-O> only executes one Normal- (or Ex-) mode command
bad : :imap <C-space> <C-O><Leader>f:call ToggleFold()<CR>
good: :imap <C-space> <C-O><Leader>f<C-O>:call ToggleFold()<CR>
Issue 4:
this is redundant:
:imap <C-space> <C-O><Leader>f<C-O>:call ToggleFold()<CR>
why not use
:imap <C-Space> <Esc><C-Space>gi
Issue 5:
You were on the right way: with some plugins installed, it's better to
use :nnoremap instead of :nmap (but :nmap also has its advantages ...).
For example, <CR> in Command-line mode is often remapped by plugins.
What I sometimes do is to define <SID> mappings for a few critical keys,
to protect them.
For example, to forbid remapping of <CR> in Cmdline-mode :
:cnoremap <SID><CR> <CR>
and then use <SID><CR> instead of <CR> in your mappings (these mappings
must be in the same script):
:nmap <C-space> <Leader>f:call ToggleFold()<SID><CR>
Issue 6:
given you decide to use another key for <Plug>SimpleFold_Foldsearch than
<Leader>f
:nmap <Leader>g <Plug>SimpleFold_Foldsearch
now you will also have to change the mapping for <C-Space>. Thus for
<C-Space> it might be better to have <Plug>SimpleFold_Foldsearch in the
{rhs}:
:nmap <C-space> <Plug>SimpleFold_Foldsearch:call ToggleFold()<CR>
