Vim Avoid "Hit the enter key or enter a command"

Question

I have the following configuration in my .vimrc file to switch between a .c File and it's corresponding .h File

function SwitchHeader()
    w
    if(&ft=='cpp')
        e %:r.c
    elseif(&ft=='c')
        e%:r.h
    endif
endfunction

When i enter :call SwitchHeader() into the vim command line The message appears Bestätigen sie die EINGABETASTE oder geben sie einen Befehl ein which i would translate to Hit the enter key or enter a command

How can i avoid having to press enter every time i call the function, when i bind key i can use <cr> at the end of the line to insert an Enter, but how can do this in the function.

Answer 1

Use

execute ':edit ' . expand('%:r') . '.EXT'

(Note: replace .EXT by whatever you want it to be in each branch)

Also: have a look at http://www.vim.org/scripts/script.php?script_id=31

Answer 2

For everyone having the same problem: i found this vim plugin http://www.vim.org/scripts/script.php?script_id=31 which seems to have more options, like splitting the pane and so. I didn't try it, but you might give it a try.

Answer 3

In 'quick-and-dirty' scripts, the solution is often to insert the literal character into the file. In this case you would type control+v followed by the return key, to insert a character looks like an ^L but you can tell it isn't caret-ell because the cursor moves across it as one character.

Characters entered into the file this way do not tend to survive copy-and-paste, and various other means of transmission, however, they can get the job done. Sometimes it is even necessary to wrap them in a call to execute normal. For example:

execute 'normal (...commands that might generate enter prompt...)^L'

Answer 4

Try :set cmdheight=2

From :help messages

To reduce the number of hit-enter prompts:  
- Set 'cmdheight' to 2 or higher.
