remap - vim change :x function to delete buffer instead of save & quit

Question

I want to set :x in vim gui-mode to delete buffer because I always kill the whole gvim, which is kind of annoying. I know i can specifically set gui problems with if has("gui running") but don't know how to remap :x

thanks in advance

ps.: maybe the tag/term remap is wrong but I don't know the correct term, that's why google didn't provide any help at all.

Answer 1

I find the safest alternative is to use an expression abbreviation:

cnoreabbrev <expr> x getcmdtype() == ":" && getcmdline() == 'x' ? 'bd' : 'x'

This will ensure the abbreviation will only be expanded to bd when :x is used otherwise just expand to x.

For more help:

:h map-<expr>
:h getcmdtype()
:h getcmdline()

Upon further inspection there appears to be a plugin that does exactly this by Hari Krishna Dara called cmdalias.vim. It uses a variation of the technique above.
