How do I define a vim function on a single line?
Since | is used to separate commands, I thought I could just do this:
:function! SomeFunc() | return 0 | endfunction
It works fine when I type it on separate lines (entering the first line causes it to prompt for the remaining lines):
:function! SomeFunc()
return 0
endfunction
I now see this caveat at :help :bar:
These commands see the '|' as their argument, and can therefore not be
followed by another Vim command:
…
:function
Is there any way around that?
I see where it says...
You can also use to separate commands in the same way as with
'|'. To insert a use CTRL-V CTRL-J. "^@" will be shown.
But this doesn't work either:
:function! SomeFunc() <NL> return 0 <NL> endfunction
It gives this error:
E488: Trailing characters
This works if I manually type in the CTRL-V CTRL-J sequence:
:function! SomeFunc() ^@ return 0 ^@ endfunction
But that still isn't a acceptable solution because I want to be able to simply copy and paste the function! command and press Enter...

The original problem that prompted this Q was that I found a function in a plugin that I wanted to use in my own .vim scripts/config, but it was only callable as<SNR>104_mixedcase(). I wrote my own wrapper function to try to "export" it and make it easier to use from anywhere. But it didn't work to define my new wrapper function in a script file, apparently because the <SNR> is then relative to that (wrong) file. It did seem to work, however, if I simply pasted the function in the vim command line. So I thought it would be nice if I could paste that as a single line/command...

Great idea, thanks! Didn't know about :@ for sourcing the contents of registers. That (vim registers) would work well — better than copying and pasting all the way out to the system clipboard and then back into vim.

<SNR>104_means "script number 104". You can locate the script with:scriptnamesand copy the function to your vimrc.

One option would be to use exe:
exe ":function! SomeFunc() n return 0 n endfunction"
The n characters are interpreted as newlines by the double-quoted strings. This does mean you should be careful to escape any special sequences.
That said,
I want to be able to simply copy and paste the function! command and press Enter...
As romainl mentioned, your ultimate goal is not clear. If this is something you do often for some reason, maybe there's a better way to get what you want. It's a good idea to describe your problem in terms of why you need this functionality.

I see, you found a useful function in a plugin, but it's script-local. Happens every once in a while. In a case like this, I'd copy the function to my local files and make it global (or autoloaded), so it's easily callable. It's copy-pasta, but if it's just a utility function, I'd say it's not a big deal. Anyway, glad to hear you've learned new tricks, that's the value in experiments like this :).

I guess I can just copy and paste the multi-line version of the function definition... But I'm still curious if there is a way to define it with one copy-and-pastable line...

Your ultimate goal is not clear to me but you can yank the function and "source" it with
:@".– romainl

The original problem that prompted this Q was that I found a function in a plugin that I wanted to use in my own .vim scripts/config, but it was only callable as
<SNR>104_mixedcase(). I wrote my own wrapper function to try to "export" it and make it easier to use from anywhere. But it didn't work to define my new wrapper function in a script file, apparently because the <SNR> is then relative to that (wrong) file. It did seem to work, however, if I simply pasted the function in the vim command line. So I thought it would be nice if I could paste that as a single line/command...– Tyler Rick

Great idea, thanks! Didn't know about :@ for sourcing the contents of registers. That (vim registers) would work well — better than copying and pasting all the way out to the system clipboard and then back into vim.

<SNR>104_means "script number 104". You can locate the script with:scriptnamesand copy the function to your vimrc.– romainl
