Description

There are two issues:

[10046 eax@EagleMac   ~ !1!]%arc diff --base foo
Usage Exception: `arc diff` is only supported under git, hg, svn.

but arc help diff says

--base rules
    Supports: git, hg
    Additional rules for determining base revision.

is --base supported for svn or not?

Additional rules for determining base revision. provides no context for what this might be and I can find nothing under https://secure.phabricator.com/book/phabricator/article/arcanist_diff/

For (1), what output do you expect?

For (2), the documentation is here:

(1) Some reference to "commit ranges" would have been nice. I had no idea what to search for to find that page
(2) thanks

(3) the svn / no svn issue should be fixed

the svn / no svn issue should be fixed

Sorry, I still don't understand what output you expect. What did you expect arc to do?

actually, I misunderstood, the output, sorry about that.

I read Usage Exception: arc diff` is only supported under git, hg, svn. is saying that --base` was supported under svn as well. This was wrong.

Sorry for the noise.
