diff-ext for Nautilus

[Sergey Zorin]

I'm glad to announce first ever release of diff-ext for UNIX platform. 
Diff-ext now supports Nautilus file manager!
Give it a try, send in your comments and suggestions.

Serg.

I compiled and installed it into /usr and pointed setup to /usr/bin/meld. What now?
I kind of disagree that a Help file would be helpful. "Essential" is the term we're looking for ;)

[Sergey Zorin]

I posted "Getting Started with gdiff-ext" guide at http://diff-ext.sourceforge.net/gdiff-ext-guide.shtml.
Hope this will shed some light on the diff-ext.

PS: note that the guide mentions gdiffextsetup program that is the new name for diff-ext-setup.

Serg.

Hi again,

Thanks for the guide.

I am however having a major issue with diff-ext 0.2.2 installed into /usr:
With diff-ext installed, Nautilus always crashes as soon as I right-click on files on the desktop (~Desktop). Gnome works fine again after uninstalling diff-ext and restarting nautilus with -q.

This is on Debian sid with Gnome 2.14.3. Let me know if you need more info.

Cheers

[Sergey Zorin]

Could you please send the stack trace.

Serg.

[Ruediger Arp]

Sorry for the delay, here's the stack trace, I had to run it as root since running as mortal user did not produce any output.

diff-ext was making my Nautilus freeze up, until I added the key "icons" with the value "diff-ext" in the diff-ext section in GConf. I mentioned this in a comment for a bugreport that was most likely the same issue that I had.

However now I have other problems. Nautilus often forgets its settings and behaves as the default Debian Nautilus instead of like the options in Ubuntu say it should. This is really weird. For example, what I usually notice first is that files aren't sorted separately from directories. They're also displayed in icon view, instead of list view (can't remember if this is a Ubuntu default or if I've set it myself, but regardless, it's "forgotten" by Nautilus for some reason...) and as soon as I open a new folder window, it doesn't have a toolbar or a sidebar anymore.

So... my best guess is that diff-ext is interfering with GConf in some way? Either way I'll uninstall diff-ext now and wait until this has been fixed. I really hope Sergey can pull it off, because this is an awesome extension.

[Luca Di Stefano]

the same on gentoo with nautilus 2.18.3 and gdiff-ext 0.2.4.
nautilus forgets settings and crashes each time I close it.

It should fix the problem with crashing Nautilus.
