I installed camlp4-3.08.3-1, and this also solved the other build problem as well that looked like to be a PATH problem. when i run git-viz in a git-controlled directory, it seems to start up fine, but i get an error message: Could not execute dot. Closing that window gives me the ability to do an 'Open', but git-viz does not seem to recognize any of my GIT repositories as such. (perhaps there's some GIT version dependency? I've got Linus' latest greatest installed.) The configure script should signal an error when it doesn't find camlp4, I'll change that. fyi, it also didnt check for ocaml and lablgtk.

Re: git-viz tool for visualising commit trees
Dear diary, on Thu, Apr 21, 2005 at 04:47:16PM CEST, I got a letter where Ingo Molnar [EMAIL PROTECTED] told me that... is the 'diff with ancestor' feature supposed to work at this early stage? (it just does nothing when i click on it. It correctly offers two ancestors for merge points, but does nothing there either.) Doesn't it require git diff? -- Petr Pasky Baudis Stuff: http://pasky.or.cz/ C++: an octopus made by nailing extra legs onto a dog. -- Steve Taylor - To unsubscribe from this list: send the line unsubscribe git in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

* Olivier Andrieu [EMAIL PROTECTED] wrote: - naming the boxes by key is quite meaningless. It would be more informative to see the author's email shortcuts in the boxes. Also, it would be nice to see some simple graphical feedback about the size and scope of a changeset, without having to zoom on it. That's interesting. What do you mean exactly by scope ? usually there are two interesting things about a patchset: how many lines does it change, and how many files. Patches that change lots of files (but change only a couple of lines in every file) have a 'large' scope. Patches that change 1-2 files have a 'small' scope. A pure 'number of lines changed' metric is useful too. Generally patches that have either a large linecount or a large scope are more interesting. (I'm not sure how this could be displayed - perhaps the size of the rectangle could vary to a certain degree? Perhaps the shape too? Something non-numeric, so that one gets immediate visual feedback.) i guess you know it, and i'm definitely not complaining about prototype code, but rendering is quite slow: drawing the 340 changesets in the current kernel repository takes 15 seconds on a 2 GHz P4. Drawing the full kernel history (63,000 changesets) would take more than 45 minutes on this box. the current rate of kernel development is ~2000 changesets per month, so drawing the kernel history will get 3 seconds slower every day - it will exceed 1 minute in 20 days, so this will become a pressing issue quite soon i suspect. Right, it is slow. From what I could understand with a bit of profiling, the problem is with the text canvas item for the boxes' labels. I guess libgnomecanvas isn't using Pango properly or something: it lookups the font with fontconfig each time I create such an item. I'm not sure what I can do about this. when the redrawing happens in the visible area then one can see how really slow it is: 100-200 msec per rectangle (!). It works with Petr Baudis' git-pasky (it calls `git diff'). I don't know how to do that with the canonical git. ah, ok. I guess it will start working once Petr's changes are merged into Linus' tree.
