Subject: [PATCH] mergetool: rename bc3 to bc
Beyond Compare version 4 works the same way as version 3, so rename
the existing "bc3" adaptor to just "bc", while keeping "bc3" as a
backward compatible wrapper.

We should drop "bc3" here. This is the list of candidates that
is used when no configuration exists. Listing "bc" twice here
implies that we might try that candidate twice.
Otherwise, this patch looks like the right way to go ~ it makes
"bc" available and keeps compatibility for "bc3".
If we wanted to phase out "bc3" for Git 3.0 we could start
warning inside of the "bc3" scriptlet, but I don't see any
reason to do so a.t.m.
Thanks,

Thanks for the quick and great feedback. This looks good to me. I used “bc4" just for consistency sake and to preserve backwards compatibility, but introducing “bc” as a generic backend looks indeed as a better approach. It’s even future safe, because it doesn’t prevent introducing bc5 if required later on.

I didn't carefully look at the code that uses this list to see if we
have to list everything or can list just the ones we recommend, and
erred on the safer side (unlike the one for completion where I
omitted bc3 as "deprecated").
I'll let mergetools experts decide when rolling the final patch ;-)

Yes we should, but git-gui is not in my bailiwick, and shouldn't be
done relative to my tree anyway. I'll Cc this message to Pat.

The patch is indeed not needed, which is why I haven't cared to provide it so
far although I'm now using Beyond Compare 4 instead of version 3 myself.

That's exactly the only reason I could think of why it could be nice to have a
"bc4".

IMHO, the only reason not to just have a single "bc" is to maintain backward
compatibility for users already using "bc3". But for the sake of cleaner code,
personally I'd be fine with that minor backward compatibility breakage.

Beyond Compare versions prior to 3 do not run on Linux, but only on Windows,
which is why I did not care to submit a patch.

That indeed sounds like the best approach.

Why keep bc3 here?
And shouldn't we update git-gui/lib/mergetool.tcl, too?

It seems that ffe6dc08 (mergetool--lib: Add Beyond Compare 3 as a
tool, 2011-02-27) is the first mention of "Beyond Compare" and it
only was interested in version 3 and nothing else.
Perhaps something like this, so that existing users can still use
"bc3" and other people can use "bc" if it bothers them that they
have to say "3" when the backend driver works with both 3 and 4?

Hmph, if this is identical to mergetools/bc3, why is the patch even
needed? Do we auto-detect something and try to use bc4 which does
not exist and fail, and we must supply a copy as bc4 to prevent it?
It may feel somewhat strange to have to say "mergetool --tool=bc3"
when you know what you have is version 4 and not version 3, but in
that case, I wonder if there are reasons why calling both versions
just "bc" is a bad idea. And assuming that version 5 and later
would keep the same interface, we will not have to worry about that
"I have version 7 why do I have to say 3?" if we can go that route.
Perhaps version 2 and before are unusable as a mergetool backend or
something?
