For whatever it's worth, I've written a PyQt4-based git gui.  For lack
of a better name I call it ugit, as in "I git, you git, we all git
with ugit" (or something silly like that).

Though there's still a few things remaining to be implemented, the
bulk of the initial groundwork is already done.  All you need to
build/run it is python and pyqt4 (pyuic4).  I've deliberately tried to
keep the interface similar to git-gui for now since it is obviously
based on it, but that's not a requirement.

Of course there are some notable things missing (such as proper i18n),
but it's not too bad for a first draft.

For more details (and the code) see:
http://repo.or.cz/w/ugit.git

Enjoy,

Cannot start the thing...

$ python bin/ugit.py
Traceback (most recent call last):
  File "bin/ugit.py", line 6, in <module>
    from ugitlibs.models import GitModel
ImportError: No module named ugitlibs.models

Some hints?

Where did you install it?

Because I had the same problem when I did
./configure
because it puts the python stuff in
/usr/local/python2.5/site-packages/... and python doesn't look there
by default.
./configure --prefix=/usr fixed that for me (and I'm sure there's a
way to tell python to look in /usr/local... too, but I can't be
bothered with that.

I re-installed without the prefix and that error disappeared, but now I get
Traceback (most recent call last):
  File "/usr/local/bin/ugit", line 12, in <module>
    view = GitView (app.activeWindow())
  File "../py/views.py", line 15, in __init__
  File "default/ui/Window.py", line 43, in setupUi
AttributeError: setLeftMargin

I'm too busy to poke around and see why that's happening, but
hopefully someone can.

This with Python 2.5.1 and PyQt4 4.2-8 (from an up-to-date Fedora 8 install)

I have only $HOME/bin in path so I manually moved main 4 files and
directory ugitlibs under   bin/

$HOME/bin  -> ugit ugit.py uit.pyc ugit.pyo
                   -> ugitlibs/ -> with remaining files


And it worked.

Hello

To allow python to find the libs you just have to set $PYTHONPATH to
include $PREFIX/lib/python2.4/site-packages  (change that 2.4 to 2.5
if you're on python2.5).  Of course in a packaged form that wouldn't
be an issue since $PREFIX=/usr, but for test-driving it you'd probably
need to set PYTHONPATH.  Are there any distros that don't use
$PREFIX/lib/python2.x/site-packages?  If not, it wouldn't hurt to add
an assumption about the installation layout into the main script.

As for the setLeftMarginError -- That could be because you have py/qt
4.2.  The ui files were generated with designer-qt4 (4.3.x) so you
might need a more recent pyqt4.  I'll see if I can grab an older
version of pyqt and use it for all of the ui designs  (.ui files are
probably forward but not backwards compatible).

That was it - as a matter of fact, the package updater for my distro
was asking me to upgrade.

Well done, though I don't think I'm going to abandon git-gui quite yet.

The most valuable thing git-gui does, IMHO, is give you fine control
over what you stage in a commit. The two-paned view of staged and
unstaged changes with the view of the actual changes makes it really
easy to see exactly what you are committing. And the graphical
"{Un}stage hunk for commit" business, which ugit seems to lack so far,
is really excellent - it's much easier to use than git add -i for
partial adds.

I would like to see git add -i's hunk-splitting functionality in a
graphical tool for that matter.

Anyway, ugit is very good for a first draft; its text display beats
whats in git-gui in a big way (and I would *hope* qt4 would beat
Tcl/Tk at that at least).

One suggestion:
For Westerners like me, having "staged" on the left and "unstaged" on
the right seems a little unnatural; I'd be curious to hear others'
opinions on that.

Are you just using the wrong fonts under git-gui?  I mean both
Tk and qt4 are drawing text through your windowing system, from
the same pool of font files... if qt4 can draw nice text then
so can Tk, right?

I don't know much about graphical toolkits and the like, but I think
that the more modern ones have fancy features like antialiasing and
subpixel rendering, which makes a big difference when you're working
on a laptop with a tiny screen.

Take a look for yourself:
http://img441.imageshack.us/img441/492/comparejd6.png

They are obviously using different fonts there (because I can't figure
out what font ugit is using) but there is a difference in rendering
quality to be sure.

The qt stuff fits better with the rest of my system better too (even
though I'm using gnome) - it's entirely the result of Tk being
lightweight and a million years old, when UI conventions were
different (like every menu being detachable, and antique scrollbars).
I'm not here to start a toolkit flame war (we had a toolkit dogpile on
the list last week, I think) I'm just pointing out that Tk is from a
different era.

I use git-gui and gitk for my git graphical needs because they rock
and at the end of the day, the fonts and antialiasing aren't that big
of a deal, especially since I'm usually doing quick scans and searches
over the information those tools display, not reading novels in them.

Oh, that's a good point.  On my Mac OS X system with the aqua port
of Tk the fonts render just as good as anything else on this box.
I guess the Aqua port of Tk is just better than the X11 port of
Tk is.  :)

Be nice to know what ugit is using, or really how its guessing the
default font.  I wonder what font you are using with your git-gui.
The default Tk picks on X11 is basically crap, but git-gui goes
with your system default as its own default.

Yes.  The tile extension in 8.5 should actually improve this quite
a bit; as I understand it there is a GTK backend for Tk with that
set of extensions, making the UI look more modern on X11, assuming
GTK was available when Tk was compiled, etc...

I have yet to make git-gui use the tile extension.  Its however
planned to happen in the near-ish future.

Good points.  Features win over pretty most of the time.  But at
some point pretty is important; especially to new user adoption.
Plus if you are looking at it all day long it shouldn't be jarring
to the eyes.  But git-gui still isn't even where I want it ot
be feature-wise.  E.g. I'd *love* to teach it inotify support,
so you don't even need to have that Rescan button.

On that note, did you see what I wrote above, about having "split
hunk" functionality? That would be killer. I know, I know, I should
write a patch... well, I've got a paper deadline coming up, and the
time it takes me to run git add -i over some clicks in git-gui plus
the time to figure out how to add that feature doesn't balance...

I had a patch for splitting hunks in git-gui in August, but there were 
some issues that I did not yet resolve.  If you want to work on it, I'll 
gladly share that patch with you.

[PATCH] Teach git-gui to split hunks

[Johannes Schindelin]

When you select the context menu item "Split Hunk" in the diff area,
git-gui will now split the current hunk so that a new hunk starts at
the current position.

For this to work, apply has to be called with --unidiff-zero, since
the new hunks can start or stop with a "-" or "+" line.

	This was the next step that I did not yet quite complete:

+proc get_context_lines {line_number context_count direction variable} {
+       global ui_diff
+       upvar result $variable
+
+       set count 0
+       set result ""
+       for {set i $line_number} {$count < $context_count} {incr i $direction} {
+               switch -exact -- [$ui_diff get $i.0] {
+                       " " {
+                               append result [$ui_diff get $i.0 "$i.lineend"]
+                               incr count
+                       }
+                       "-" {
+                               append result [$ui_diff get $i.0 "$i.lineend"]
+                               incr count
+                       }
+                       "@" {
+                               return $count
+                       }
+                       "" {
+                               return $count
+                       }
+               }
+       }
+}

	Of course, this function would be used to add some context 
	to the new hunk boundaries (if needed), and to adjust the contexts
	of the remaining hunks whenever some hunk was applied.

	... and then get rid of that ugly unidiff-zero option.

Well, the question was not very well stated.  I know what it means --
remove that old line, without replacing with the corrected/updated one.
The real question is how would that be useful?

The thing is: sometimes there is a patch which contains just one garbage 
line.  (I am talking about my current working tree, so you are not allowed 
to be offended by my language in this case.)

The thing I would like to do is right click on that line, start a new 
hunk, then right click on the next line to start yet another hunk, and 
apply this and the first hunk.

It is a lazy way to edit a patch.

I often get big hunk just because I modified whitespaces around  
relevent pieces of code, the ability to segment the changes and only  
pick isolated and specific lines for a commit (not commiting  
whitespaces surrounding real code changes) would be very welcome.
Maybe I should know better, but the actual hunk selection in git gui  
is quite good already, but the ability to be more precise on how a  
hunk is defined is a welcome change.

Oh, I wasn't questioning the usefulness of hunk splitting in general.
It is sometimes useful and that is why we have "add -i".

If you have something like this:

        @@ -j,k +l,m @@
         common 1
         common 2
        -preimage
        +postimage
         common 3
        -deleted
         common 4
         common 5

I think it makes sense to split it into two logical (overlapping) hunks:

        @@ -j,(k-3) +l,(m-2) @@
         common 1
         common 2
        -preimage
        +postimage

and

        @@ -j,(k-3) +l,(m-3) @@
         common 3
        -deleted
         common 4
         common 5

and being able to apply one of them independent from the other, or
re-combine them back into one hunk.

I was just questioning if it makes sense to split a hunk like this in
the middle of -/+ lines:

	@@ -j,k +l,m @@
	 common
	 common
	-pre 1
	-pre 2
        -pre 3
        +post 1
	+post 2
	 common

You could split between "-pre 2" and "-pre 3", but I do not think that
would be so useful.  It is a different story if you allowed the above to
first be transformed into this way (assuming that "pre 1" and "pre 2"
corresponds to "post 1"):

	@@ -j,k +l,m @@
	 common
	 common
	-pre 1
	-pre 2
        +post 1

and then be split between "+post 1" and "-pre 3".  That may make sense
in some context.

I don't know if it would be useful, but I think the more important  
concern here is consistency. ie. it should split hunks the same way  
"git add -i" does. Both "git gui" and "git add -i" are official parts  
of Git, so in the interests of coherency they should share the same  
concept of "what it means to split a hunk".

"git add -i" considers any hunk where a there are multiple groups of  
deletions and/or insertions separated by context lines to be  
"splittable" (on the boundaries defined by those intervening context  
line), and all others to be unsplittable. I think this is a fairly  
intuitive way to conceptualize splitting, so if it comes down to  
making "git gui" split like "git add -i", or making "git add -i" split  
like this patch proposes that "git gui" should do it, then I'd vote  
for the former.

Cheers,
Wincent

NACK! --unidiff-zero eats your data.

1. Prepare a modification that adds 2 lines that are *not* adjacent, like this:

	@@ -6,6 +6,8 @@ git-checkout [options] [<branch>] [<paths>...]

	 f           proceed even if the index or working tree is not HEAD
	 m           merge local modifications into the new branch

2. Reduce context to zero.
3. Stage *second* hunk.

Result: It is staged at the wrong place:

Reason: --unidiff-zero can only look at the line numbers. And those are
wrong because it doesn't account for the shift in line numbers caused by the
first hunk.

Yea, don't worry about that, I won't be applying any patch to git-gui
that feeds data to git-apply with --undiff-zero.  Not unless its
completely bullet-proof that the hunk headers will *never* be wrong.

I'd rather always apply with context and let git-apply do its thing
to validate the hunks.  If you can get the hunk headers computed
right you can also get the context computed right, which means
git-apply can actually verify the patch can be applied, thus double
checking the splitter.

You do not have to do "unidiff zero".  Suppose you have this hunk you
need to split.

Think about taking the s/i.e./that is,/ substitution without taking the
other s/_needs_/needs/ substitution.  You do not split the hunk between
two '-' lines, but effectively make it into this hunk instead:

That is, , if you want to do finer grained hunk splitting than what "git
add -p" lets you do, you do _not_ let user specify "I want to split the
hunk into two, before this point and after this point".  Instead, let
the user pick zero or more '-' line and zero or more '+' line, and
adjust the context around it.  An unpicked '-' line becomes the common
context, and an unpicked '+' line disappears.  After that, you recount
the diff.  That way, you do not have to do any "unidiff zero" cop-out.

At the same time, you can stash away what was _not_ picked, creating two
variants to be applied on top of the result of applying (or not
applying) the picked patch, if you want to allow "undo".

Then I can stage either one. After that operation, git-gui refreshes the

It's probably sufficient to have an option "Stage this Line": Once you have
staged enough lines, the hunk will be split automatically by the current
number-of-context-lines setting.

And your hand falls off... ;-)

Seriously, I often have a big chunk of changes, for example with 
an indentation change, where I want to stage everything _but_ one line in 
the middle.  Just staging that, "git checkout <file>" and fixing the 
indentation of that single line speeds up my procedure vastly.

[PATCH] git-gui: Move frequently used commands to the top of the context menu.

[Johannes Sixt]

From: Johannes Sixt <johannes.sixt@telecom.at>

"Stage/Unstage Hunk" is probably the most frequently used command of the
patch context menu *and* it is not available in some other form than
the context menu. Therefore, it should go to the top. "Less Context" and
"More Context" entries are also not easily available otherwise, and are
therefore, moved second. The other entries are available via key strokes
(Copy, Paste, Refresh) or rarly used (Font Size, Options) and can go last.

 Not with this patch.

 And, obviously, "Stage this Line" is accompanied by "Unstage this Line".
 So when you want to stage a lot *except* one line, then you better
 stage the lot, then *unstage* one line.

Interesting. I had to start it like this:

	$ export PYTHONPATH=$(pwd)/build/default:$(pwd)/build/default/ui
	$ python ./build/default/bin/ugit.pyc

It has some problem with merges in "Git Commit Browser": takes a lot
of CPU and very slowly generates a very big diff.

The diff view is very ... dark. Out of place, when the rest of the
interface corresponds to system theme (mine is rather light).

Yeah, it's dark here (Mac OS X), too -- doesn't look very
friendly.

It took me some time to get the full Qt, SIP, PyQT toolchain
running ... below's my first (tiny) fix that makes
"Branch > Create ..." work if you don't select track.

I have added it to http://git.or.cz/gitwiki/InterfacesFrontendsAndTools

Funny that both (h)gct and Qct, which are commit tools too (although
multi-SCM) are also written in PyQt...

Not to belabor the point, but just some comments, since this seems
to come up often enough...

Yes, it is a known issue that Tk on unix still has the "old look"
out of the box. Some of this is just due to how the defaults
for some of the options are shipped. The default options for 8.5
have changed, so it is a little better, but Tile is really better.

The same with fonts. Anti-aliased fonts for unix have not been
supported, but in 8.5 they are.

8.5 is due out by the end of this week I believe.

Tile will ship with 8.5, but it is also an extension that can be used
with 8.4.

Here's some screenshots to give you an example of Tk with Tile with
Qt theme (add-on theme).

I have not used it, but this may help in regards to the
inotify stuff:
