Subject: Re: [PATCHv5 00/17] Diff machine: highlight moved lines.
Date: Thu, 25 May 2017 15:44:45 +0900 [thread overview]
Message-ID: <xmqq7f15e8pu.fsf@gitster.mtv.corp.google.com> (raw)
In-Reply-To: <20170524214036.29623-1-sbeller@google.com> (Stefan Beller's message of "Wed, 24 May 2017 14:40:19 -0700")
I was trying to see how this is useful in code moving change, with
this command line:
$ git -c color.moved diff js/blame-lib~6 js/blame-lib blame.c blame.h builtin/blame.c
Some random observations:
* You do not seem to have any command line option yet. I guess
that is OK while the series is still in RFC state, but when we
are ready to seriously start considering this for 'next', we'd
need something like --color-moved that can be used across "diff",
"log -p" and "show".
* As configuration variable names go, "color.moved" is probably in
a wrong section. Perhaps "diff.colorMoved" or something?
* The fact that I am using
[diff "color"]
old = red reverse
whitespace = blue reverse
on a "black ink on white paper" terminal might have an effect on
this, but lines printed in either bold green and on green
background (i.e. not new ones but are the ones moved from
elsewhere) stood out a lot more prominently than lines printed in
green (i.e. truly new additions), and I felt that this is totally
backwards from what I needed for this exercise. That is, while
reviewing a code moving change, I want to be able to concentrate
primarily of three things:
- What are the new lines that are *not* moved from elsewhere?
Did the submitter try to sneak in unrelated changes?
- What are the changes that are truly lost, not moved to
elsewhere?
- Do the lines moved from elsewhere form a coherent whole? Where
is the boundary between blocks of text that are copied? Do
adjacent two blocks of moved text come from the same old place
next to each other?
Using colors that stand out more prominently than for the regular
new/old lines is counter-productive for all of these, especially
for the first two purposes. I may suggest using cyan (or any
color that is very close to the background) so that the presense
of moved lines are merely felt without being distracting. IOW,
while reviewing code moving patch, moved parts want to be dimmed,
not highlighted.
