The other day I was preparing a talk with a collegue on revision
control, and we've also show how to use basic diff and patch.

Even if most of the work was done in emacs, we used vim to show the diff
file, since it's much more colorful.

Anyway after I solved customizing some faces

 '(diff-added ((t (:inherit diff-changed :background "black" :foreground "Yellow"))))
 '(diff-changed ((nil (:foreground "medium purple"))))
 '(diff-header ((((class color) (min-colors 88) (background dark)) (:background "grey22" :foreground "red" :height 1.2))))
 '(diff-indicator-removed ((t (:inherit diff-removed))))
 '(diff-removed ((t (:background "black" :foreground "indian red"))))

Now it's even too much contrast :D
But then I thought, wouldn't it be possible to show the normal syntax
highlighting of the given mode and use some background/font style to
differentiate what's to add/remove?

I think even if it's a diff code would look more clear and nice if it's
in the "right" colors...

Sorry but I don't see that much difference in diff+, the only things
done more is

calls `fit-frame-if-one-window' at end, which by the way I don't find
anywhere in the doc, not even with M-x apropos.

My desire was to see the diff with the syntax highlighting of the
original language, it it could be possible...

If I understand you correctly you mean that I should not use diff- but
only ediff.
Well ediff is more interactive and very nice, but if sometimes I open a
file .diff I would like to see it better.

For example I would also like to "fix" magit about that
- now even if I changed the faces for diff-mode it still shows me non colored
- I would like to see below my commit message the whole diff, so I don't
  have to manually expand the files to see again what was really modified

Sorry, I meant diff-mode-.el, which does deal with highlighting (unlike
diff+.el).  The second link should have been this:
http://www.emacswiki.org/emacs/diff-mode-.el

If it helps, fine.  If not...

> My desire was to see the diff with the syntax

diff-mode-.el does not help with that.

For that, you will likely want to (a) visit the buffers/files in the proper mode
with font-locking, and then (b) copy text from there (with faces) to the diff
output buffer.  Or put the other way around: follow each diff from the `diff'
output buffer to a buffer for the original file and copy text (with faces) back
from there.

But that sounds onerous in terms of efficiency.  Remember that `diff' itself
runs and produces its output outside of Emacs.  You need not even be visiting
the diffed files within Emacs.

Why don't you just use `ediff'?  With `ediff' you see the files within Emacs,
font-locked.

I think you would have to use overlays for that.  I don't know of any
diff-based package which does that.

According to Emacs Lisp Reference, text properties are better for this
kind of task:

Well I was meaning that your face-names are wrong ie you need to say
ediff-added etc
But now I see I am wrong :-) If you load ediff-mode you get those if
you load diff mode you get those

Ediff is really nice, but it's a bit cumbersome.
I mean if I only want to see the diff and apply what I want how do I use
ediff?
ediff is very interactive and it makes a lot of color noise, moreover it
opens another small frame which on 
"GNU Emacs 23.2.1 (x86_64-apple-darwin10.3.0, NS apple-appkit-1038.29) of
2010-05-09 on linc"
I think is a bit buggy, since if I press "q" it doesn't disappear but I
have to close it manually.

As I discussed with a collegue, one of the problem of emacs are the
non-inviting defaults.

Since no long ago the transient-mark-mode was not enabled by default
(just an example).
I understand that it must be compatible from Dos to Solaris, but many
people try it, see that the defaults suck (from a normal user
perspective) and they abandon, which is a pity (or "natural selection" maybe).

But that's another topic...

M-x report-emacs-bug.  Typing `q' in the Ediff control buffer should always quit
Ediff (after you answer `y' to confirm).  If the Ediff control buffer is in its
own frame, then be sure that frame has the input focus when you type `q'.

If `q' doesn't work for you, please report it as a bug, providing a recipe that
starts with `emacs -Q'.

Yes, it is.  And probably better for emacs-devel than for help-gnu-emacs.

This is never going to be solved.  Emacs lacks the resources to pay
for a team dedicated to usability issues, more so if you think about
how many platforms it runs on.  Moreover, it is maintained by advanced
users, which are unlikely to understand the needs of beginners.

I applaud your effort to use Emacs for diffs.  I gave up very quickly
and to this day I still stick to WinMerge.

"Tools->Apply patch" from the menu bar.  Is this what you want?

When you press `q', Emacs asks a question.  You must answer `y' (yes)
to get the control frame close automatically.  Did you do that?

That's not true.  Usability is quite high on the developers' agenda.
If you report usability problems as bugs, they will be handled.

Feel free to use LoseMerge, Ediff beats it any time with both hands
behind its back.  You gave up too quickly.

I think the default behaviour of opening up a small frame for the
control panel is annoying. It is probably the only package that does
that.

I was going to suggest people donate resources to help out. But I
checked the GNU website and it only allows donation to FSF not Emacs.

Every default will annoy someone.  Which is why you can customize
them; in this case, Ediff gives you the ediff-window-setup-function
option to do precisely that.

I do not doubt it.  They just can't understand such issues however.
It's not their faults.  They are geeks, just like me and - I think -
you.  If we were them, we couldn't do any better.

Newbies flock to other editors because newbies find such editors
easier to use.  Geeks know such editors just seem easier, or are
easier just in the short run, and shrug their shoulders.

I don't doubt it.  However, as many things Emacs, its interface seems
foreign.  I couldn't find a way to compare directories and have a
summary of changed files, from which navigate to such files.  If
someone could post a video about how to accomplish such a task with
Emacs...

Yes but well, something where I can read and analyze the diff before
patching one by one is better.
Diff-mode is perfectly fine, it would be perfect with a bit more
font-locking but that's already good like this...

Yes sure I did, and in fact it quits, but the small window remain there
until I close it manually.
But now I tried with "Emacs -Q" and this works fine, so it's something
related to my configuration...

How about this? Side-by-side comparison, no external control frame,
and once you quit, it goes back to your previous visual configuration...

I don't think it should look easy for newbies, but it surely look nice
and not too complex for already skilled programmers, that are maybe used
to vim or something like that.

It is much more powerful than all the others from my experience, but in
the first few months is really hard to get through and be really
productive with it...

Well I'm not an expert but that seemed rather easy,
ediff-directories is not what you want?
It gives you a summary and then you can do many things from there...

Anyway the error I get when in my configuration I try to kill the ediff
session is

--8<---------------cut here---------------start------------->8---
Quit this Ediff session & show containing session group? (y or n) 
ediff-cleanup-mess: Attempt to delete minibuffer or sole ordinary window
--8<---------------cut here---------------end--------------->8---

The command ediff-patch-file, which is run by that menu item, can take
the patch from a buffer (see its doc string for the details).  So you
could study the patch, and then apply it right from the buffer.

Yep, looks like that.

Thank you for the tip.  However, ediff-directories requires you to
navigate directories looking for differences.  OTOH, WinMerge does
that automatically and shows you a colorized summary, from wich is
very easy to navigate from and to single files.  Here is a screenshot:
http://winmerge.org/about/screenshots/foldercmp.png

Way quicker.

Similarly with dired. The thing is that I generally find that at first I
hate why certain things are. It's only later that you realise, as you
become familiar with a tool, why its like that. And invariably there is
a good reason. This happens all the time in Emacs. Unfortunately I
believe thats the wrong way to build SW if you have any interest in
attracting new users : better, in that case, to default for "nOOb
morons" (and I include myself in that ;)) and let the power users
customise as they see fit. The reluctance to CUA by default would be one
such an example or the reluctance to turn on the X clipboard by
default. At least one of which has now changed I believe.

Skilled programmers can still be Emacs noobies.

Great.  Now you can report a bug: `M-x report-emacs-bug'.  

First: Load library `ediff-util.el' (the library where `ediff-cleanup-mess' is
defined.  Be sure to include the ".el" here, so you don't just load the
byte-compiled file.

Second: `M-x set-variable RET debug-on-error RET t RET', to show a backtrace
when the error is raised.  Include the backtrace in your bug report.


_If_ you want to dig further to help find the problem, you can try to follow
function `ediff-cleanup-mess' in the debugger:

M-x debug-on-entry RET ediff-cleanup-mess RET

When you try to quit `ediff', the debugger will open when `ediff-cleanup-mess'
is invoked.  Use `d' to step through the debugger (or `c' to skip through a
step).  You can add any info you learn this way to your bug report.  (You can
use command `cancel-debug-on-entry' to cancel `debug-on-entry'.)

Essentially, the problem here is that there is only one window in the Ediff
control frame, and Emacs tries to delete that lone window, which is a no-no.
What Emacs should be doing here (probably) is to delete the frame.  Instead, it
thinks you want to keep the frame and it complains that it cannot delete the
last window in the frame.  IMO, this is a bug.

Ok thanks a lot I'll do it.
BUT I only experience this with my configuratio as I said.
If I do Emacs -Q I don't have this problem, so I'm not 100% sure that I
should send a bug report until I didn't find the source...

You can provide info on your configuration in the bug report. Of course, if you
can narrow it down to a small part of your configuration, that will help.

Look for things in your config such as non-nil `pop-up-frames'.  Look for
whatever you think you might have done that causes Ediff to use a separate frame
for its control window.

The general rule for narrowing down your config to find a problem cause is to
use binary search: remove/comment-out half of your init file, then 3/4, then
7/8,... until you find the part that provokes the error.  Binary search is very
quick.

She said "you can do many things from there".  Did you try? did you
try to type `?' and read the short descriptions of the available
commands?  You could, for example, try "==".

Thank you for the tip.  Of course I tried and missed "==" because
"Useful commands:" described it as "for each session, show which files
are identical".  Since I was looking for different files, I tried "D"
instead ("show differences among directories").  However, "==" still
requires you to navigate through directories.  This is grunt work and
is no match for WinMerge's summary.

And, for example, some simple colors would also make ediff-directories
look much nicer.
In this case however I didn't find any face to customize (am I wrong).

Sometimes people choose things just because they look better, even if
sometimes they're not at all the best tools...

No, it doesn't.

This shows Ediff's unfriendliness: I tried it and couldn't figure it
out.

That would be neat, yes.  Making it work reliably might be difficult,
but a first shot might not be that hard.
Some of the problems:
- the code chunk might be difficult to analyze correctly without its
  context (e.g. the code chunk may start in the middle of
  a comment/string/...).
- for people using the default font-lock settings, it might be difficult
  to find a set of background colors to use for added/removed/changed
  that doesn't make some of the text hard to read.  For people using
  font-lock settings like mine (i.e. mostly all black-on-white, where
  most faces changes the bold/italics rather than the color) OTOH it
  would work fine.  Note that smerge-mode already works similarly, so
  it's not a new problem.

As Andrea already pointed out there's ediff-directories, but I've
always found it terribly counter-intuitive. That was actually one of
the reasons that pushed me to write the Sunrise Commander:

    http://www.emacswiki.org/emacs/Sunrise_Commander

If comparing files and directories is as important to your work as it
is for mine, give it a try:

0) Install Sunrise
1) cd to the directories to compare (in left and right panes)
2) press C-M-=
3) press one of d, s, a, n or c to compare by Date, Size, date And
size or file Contents
4) use = to run diff or C-= to run ediff on the files marked.

This facility is not limited to comparing two directories in the file
system, it actually compares whatever left and right panes contain at
the moment it's invoked: e.g. the results of find/locate operations,
contents of compressed archives, etc.

What a nifty package!  Very intuitive (at least from my background).
Congratulations.  I will be checking it out.

I've tried the procedure you've suggested, but it doesn't run a
recursive comparison, which is what I'm after.  Thank you anyway.

To make a recursive comparison in Sunrise you first need to "flatten"
the tree:

1.1) press C-c C-n to bring up find by name
1.2) type in "*" (a single asterisk) and press Return

this will recursively display all the contents of the current
directory, including all sub-directories. Alternatively:

1.1) press C-c C-f to bring up find with args
1.2) type in "-not -type d" and press Return

this will recursively display everything that is *not* a
directory. There are many other ways to flatten the tree, so the pane
shows exactly what you're interested in - after that's done you can
perform your comparison.

P.S. Press C-c C-c to return to normal mode ;)
