Well, this patch is actually specific to a particular keyboard layout!
It improves things only for a layout where you get @ and { using a shift
key.
For a german keyboard layout, you get @{u} from
hold AltGr (Meta)
press q
press 7
release AltGr
press u
hold AltGr
press 0
For me, an improvement would be to have the alias
@{↓}
for @{u} so that I can hold AltGr throughout and press q7u0. Which would
be very nice, pictorially :)
In general git could benefit from a rev alias mechanism. This idea has
come up several times, but in order to be really useful, we would need
that to be more general than textual replacements and allow for macro
like replacements such as
git config revalias.new "\1@{1}..\1"
to be used as, say
git log @{new(origin/next)}
after a fetch. (No, I'm not suggesting that specific syntax here.)
As a simpler case, a user could tailor to her keyboard layout with
git config revalias.↓ u
but for obvious reasons
git config revalias.U u
won't work.
So, maybe we could make the key part of a special revspec case
insensitive (just like config variable names) but still have a possible
payload (parameter) be case sensitive (just like config variable values)?
