"Alias" Gdiffsplit

[myitcv]

Firstly, thank you for all your excellent Vim plugins, @tpope. And to the community who are helping to answer questions like this.

Following on from #1894, in particular a question regarding d523fee

At current tip, to get the behaviour I previously had in 8e4a677 and before, I now need to call:

:leftabove Gdiffsplit! [arg]

whereas previously I was able to simply do:

:Gdiff [arg]

(no complaints mind, the new form is much more precise)

Is there a way to "alias" a command call in this way?

Thanks in advance

[tpope]

This ought to do it:

command! -bar -bang -nargs=* GDiff Gdiffsplit<bang> <args>

Nothing changed regarding ! afaik, so I've abstained from hard-coding it.

Wonderful, thank you!

For completeness' sake, I did the following:

command! -bar -bang -nargs=* -complete=customlist,fugitive#EditComplete Gdiff Gvdiffsplit! <args>

• Named Gdiff to intentionally collide with Gdiffsplit so that tab completing chooses my variant
• Provided the -complete flag so that I can enjoy the tab completion of arguments, when supplied, to my Gdiff variant (e.g. table completion of ref names likes branches)
• Hardcode the use of ! on the RHS of the command definition, because that's what I always want

Nothing changed regarding ! afaik, so I've abstained from hard-coding it.

Agreed. It's more that I've only just found out about the ! variant so started using it!
