Enormous thanks for this Darrell. I have some really good 'sea of purple' images which I wanted to test out but instead spent the day struggling with git and still no defringe module.
Rgds, Rob. -----Original Message----- From: Bruce Albert [mailto:doctordruid...@yahoo.com] Sent: 03 November 2013 14:31 To: darktable-devel Subject: Re: [darktable-devel] Help with git branches As you have already discovered, the git environment is extremely hostile to those not expert in its use. In fairness, developers work hard on their projects, and don't want to waste their time on software housekeeping, which is what git does for them. But it makes it very difficult for those who are not developers to participate in the evaluation of, and experimentation with, new software. It seems a bit unfair to advertise all the new and great features available, and then cloak them inside an unapproachable access system like git. There are other revision systems besides git, but they all share the same characteristics of being useful to those who use them all the time, and unintelligible to those who do not. Nonetheless, I fought the fight, and managed to get it working. But it took a lot of searching and experimenting; purists will say it's probably not the "right" way to do it, and it isn't, but it works. BEFORE YOU DO ANY OF THE FOLLOWING, heed well the advice already given, that for critical work, you probably don't want to use this; you want to use a more stable version. Also, be sure to backup your ~/.config/darktable directory -- really do that, because a test version of the program may change your data in such a way as to make it unusable by the regular program. I'm not sure what you mean by the "LCA branch", but if you mean the purple-defringe module, here's how I got it working: 1. Make a directory somewhere to put this, I use /opt/darktable. chown that directory to your username, so you don't have to fight permissions all the time. 3. Inside /opt/darktable, run: git clone git://github.com/darktable-org/darktable.git purple-defringe This will take some time; it downloads the main branch of darktable into a directory called defringe. 4. cd into the defringe directory, and run: curl https://github.com/darktable-org/darktable/pull/326.patch | git am This will download the purple-defringe module, and apply the patch. You will see an output that looks something like this: ----- % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 61098 100 61098 0 0 55013 0 0:00:01 0:00:01 --:--:-- 55043 Applying: defringe: Module for removing fringes (e.g. most common purple fringing, caused by longitudinal CA) - it can however also work to remove traditional CA /opt/darktable-devel/darktable/.git/rebase-apply/patch:549: trailing whitespace. warning: 1 line adds whitespace errors. Applying: defringe: ran the iop dependencies script ----- 5. Since I am using ubuntu with the https://launchpad.net/~dhor/+archive/myway ppa enabled, I get the latest regular build of darktable installed automatically, so I put the test versions in /usr/local. To do this, from your defringe directory run ./build.sh --prefix /usr/local --buildtype release Once that runs successfully, you will need to cd ./build and run sudo make install, as usual. Then you run it with "/usr/local/bin/darktable" That's it, and for me, it works. Sorry for the long post, but I literally spent two whole days figuring this out, and I think it's fair to share it with others who have been frustrated by git.
