For instance, the change could be whitespace-only, so that I want to dig deeper. ``` ## Johannes Schindelin, 2007-07-29 11:40 Subject: Re: git-gui blame: show previous commit Message-ID: URL: https://gitlist.dev/e/Pine.LNX.4.64.0707291238230.14781%40racer.site In-Reply-To: <87myxfzhk6.fsf@mid.deneb.enyo.de> ``` Hi, On Sun, 29 Jul 2007, Florian Weimer wrote: > How can I view the previous commit touching a specific line, so that I > can see what was there before?

I have no idea if "git-gui blame" can use that option, but it should not be hard for you to find out, and provide a patch if it does not yet.

Or use pickaxe search, i.e. "git log -S'' -- ". -- Jakub Narebski Warsaw, Poland ShadeHawk on #git ``` ## Shawn O.

So you'd need a pretty recent git-gui and a 1.5.3-rc0 or later git binary underneath of it to get -w enabled in blame. But it is there for the original line annotation pass (the second blame pass but first column displayed). I keep meaning to add a "Show parent commit" in the context menu of the blame viewer, but I haven't gotten around to it yet. It has been requested a few times, just hasn't been done yet. Maybe someone who wants it will submit a patch. ;-) In really recent git-gui (gitgui-0.7.5-76-g8e891fa and later) you can browse any revision you want, so you could copy the commit SHA-1 from the lower pane and paste it in as "$sha1^" into the revision expression field of the browse dialog, navigate to the file and open the blame viewer. That is really annoying, and doesn't jump you to the correct lines automatically. But it is possible to view the parent. -- Shawn. ```
