Adding a command to Vim

Question

I finally decided to try out Vim, as I am getting increasingly frustrated by GUI editors. So far, I'm loving it, but I can't find any help for a issue I'm having...

I am trying to map the command :Pyrun to :!python % in Vim using cmap. The mapping shows up fine if I type :cmap. However, on typing :Pyrun, I get this error message:

Not an editor command: Pyrun.

Here is what I'm trying in .vimrc:

:autocmd FileType python :cmap Pyrun<cr> !python %<cr> :autocmd FileType python :cmap Intpyrun<cr> !python -i %<cr> 

What can I do to solve this problem?

Answer 1

I personally prefer another approach. First create a function receiving the command arguments and then create a command to call the function:

fun! DoSomething( arg ) "{{{     echo a:arg     " Do something with your arg here endfunction "}}}  command! -nargs=* Meh call DoSomething( '<args>' ) 

So it would be like

fun! Pyrun( arg ) "{{{     execute '!python ' . expand( '%' ) endfunction "}}}  command! -nargs=* Pyrun call Pyrun( '<args>' ) 

But, there's a better way to do it in Vim. Use makeprg:

makeprg=python\ % 

Just type :make to run your current Python file. Use :copen to show error list.

I would try something like this in your .vimrc or your ftplugin/python_ft.vim

command Pyrun execute "!python %" command Intpyrun execute "!python -i %" 

Then :Pyrun and :Intpyrun should work

You could then map a function key to each

map <F5> :Pyrun<CR> map <F6> :Intpyrun<CR>
