Using Sourcetree, I see two commits.
I select them both :
Now I click on the External Diff
button :
The External tool is Beyond Compare
:
But when BeyondCompare is opened, I don't see any info which can indicate which side belongs to which commit : ( I only see some random characters)
Question:
How can I know which tab indicates which commit?
First, check the filename: it could be prefixed with LOCAL.
or REMOTE.
, as I show here.
The order, for Beyond Compare, should always be LOCAL-REMOTE
(for a diff), with in your case:
LOCAL
: the oldest commit you have selectedREMOTE
: the most recent commit you have selected.(as noted by the OP Royi Namir in the comments)
