I have created a few mappings like so:

:nnoremap <buffer> <leader>xyzABC   :call SomeFunc('ABC')<CR>
:nnoremap <buffer> <leader>xyzDE    :call SomeFunc('DE')<CR>
:nnoremap <buffer> <leader>xyzFoo18 :call SomeFunc('Foo18')<CR>
:nnoremap <buffer> <leader>xyzBar22 :call SomeFunc('Bar22')<CR>

which works as desired.

I am now looking for a possibility to create a map-template that would allow me to remove the obvious redundant parts of my mappings, something like

:nnoremap <buffer> <leader> xyz? :call SomeFunc(?)<CR>

so that I could pass any value as parameter to SomeFunc.

Is there such a possibility?

    You can use input() or getchar(). However it is probably more normal to use a command instead of a mapping for something that takes a parameter.

  • I agree with Peter's comment; commands are better suited to the job than mappings.

As @peter-rinckler said, it is probably easier to do it with a command:

command! -nargs=* Xyz :call SomeFunc(<q-args>)

Makes it possible to do (in normal mode)

:Xyz ABC

I don't really like the input() because you can't repeat those kinds of things easily.

Thanks to Peter Rincker's comment, I have found the answer:

:nnoremap <buffer> <leader> xyz :call SomeFunc(input('Param: '))<CR>

    Here is another example: nnoremap <silent> <leader>tn :exe "tabn" nr2char(getchar())<cr> . The idea is to type <leader>tn2 to navigate to tab 2.

You might want to take a look at SnipMate, which aims at giving TextMate-like snippets to vim. It proved very helpful to me, anyway.
