I am using NeoVim, and I automatically define an abbreviation for the string W every time the commandline mode starts.

However, it seems that commandline mode includes the search modes as well.

I do not want the abbreviation to exist in the search modes, so I want to delete it if it exists.

I tried maparg('W','c',v:true) and mapcheck('W','c',v:true) to check if W is defined as an abbreviation in command mode, but they do not seem to work. (here 'W' is the abbreviation I want to check for, 'c' stands for commandline mode, and true is for abbreviation -- I think)

What am I doing wrong? Thanks

EDIT: adding my code for defining the abbreviation for W:

autocmd CmdlineEnter,CmdwinEnter :,q: cnoreabbrev W w !git add %

(this allows me to add the file to the local git repo by typing :W<CR>

EDIT: Thanks to the answers below, the solution is:

cnoremap <expr> W (getcmdtype() == ':') ? "w !git add %" : "W"

Thank y'all -- it is very useful.

    Can you include the definition of the W abbreviation? mapcheck('W', 'c', v:true) works for me and returns whatever if I define it as cabbrev W whatever, not sure what's the case with your particular setting...

    Don't use auto-command here. It's pointless.

If you use a mapping instead of an abbreviation then this'll do...

:cnoremap <expr> W (getcmdtype() == ':') ? "foobar" : "W"

From command-line you get W resolving to whatever you specify where I have "foobar". OTOH, if you enter W during a search then getcmdtype() returns / or ? and the ternary expression evaluates to false and inserts "W".

And, per @filbranden, the same thing works with cabbrev...

:cabbrev <expr> W (getcmdtype() == ':') ? "foobar" : "W"

You may know this already but, FYI, there's a difference between these: the cmap version will insert the mapped string immediately after you enter the W while cabbrev requires entering an additional, non-keyword character immediately afterward (per normal abbreviation mechanics).

    Using <expr> also works with a cabbrev...

  • Wow -- Thanks guys! What does <expr> do?

    Treats the right-hand side as a Vim expression to be evaluated rather than a literal string.

    Thanks all! This answer made it unnecessary to remove the definition everytime I enter search mode.
