[fossil-users] Retro side-by-side diffs

[Richard Hipp]

For some time now, the SQLite and Fossil websites have been running on the
"retro-sbsdiff" branch of Fossil. The retro-sbsdiff branch uses a vastly
simplified format for the side-by-side diffs that omits all of the colors
and decoration and provides plain-text output - essentially the same output
as you would get on the command-line using the -y flag. Example:

http://www.sqlite.org/src/info/21695c3476

I find the "retro" side-by-side diff to be much more readable, which is why
I am using it on the SQLite and Fossil websites, as well as on my desktop.
And I've heard no complaints from users about the retro sbsdiffs on the
website. But before I merge the retro-sbsdiff branch into trunk (and hence
purge the existing colorful sbs diff from the trunk) I thought I would as
for community feedback. Are there strong preferences one way or another?

Hello,

I like how it looks. I also liked the colourful, but with tuned colours (I'm a
bit used to 'meld' and its colours, for hard diffs). I definitely prefer this
retro sbs over the colourful. I don't know if the option can be given simply as
CSS styles, though. Emitting some (html tags allowing for colourful sbs is
possible?

Apart, one feature I'd like a lot is to have sbs diffs with the *option not to skip
lines*. That's usally a nice option that sbs diffs can give over unified diffs:
full context.

Regards,
Lluís.

There are two aspects I prefer with the original:
- I think color coding makes it easier to get a quick overview of
what's happened in a diff. ("I see a lot of red" is roughly
"optimizations", "I see a lot of green" is roughly "New features").
- I haven't looked at the code lately, but does the web sbsdiff
support the width argument in some manner? For quite a few diffs I've
been looking at lately, static 80 characters wide panes leaves a lot of
empty "wasted" space, due to short lines.

Those points aside, I strongly support the idea of unifying the two,
so overall I'm for the retro sbsdiff.

My preference would be to keep the color SBS diffs, at least as a skin
option or something, since I find it easier to notice changes and match
them up. Maybe somewhere in the documentation on the header / skin, there
could be css for a default coloring of the sbs diffs that one could copy
into the header?

The layout is so fundamentally different that it's not really
possible to do it that easily. In essence, the old sbsdiff used HTML
(tables and such), the new one essentially creates a "textfile" and
shows it in a pre-formatted section.

That said, it shouldn't be impossible to get color coding with the
new/retro version: When I started working on the original sbsdiff,
someone was afraid I was going to break their javascript solution for
getting colored unified diffs. If javascript can be used to make
uncolored unified diffs colored, then I see no reason the same couldn't
be done for side-by-side diffs.

It does as of a few moments ago. The "dw=" URI query parameter controls
column width (default 80, max 255). The "dc=" query parameter controls the
number of lines of context (default 7, max 4095). Example:

I will miss the colors as I tend to rely on color in tools like tkdiff,
meld and xxdiff to give me a big picture view and to draw my eye to the
changes. The compressed summary (in the center scroll bar in tkdiff and on
the rhs in meld is extremely useful but I doubt that can be easily
replicated in fossil so maybe keeping it simple in the browser and leaving
the more powerful interface to external tools makes sense.

Just my $0.02

Looking at the new retro-look and the color look side-by-side (*, sic) I
strongly prefer the colorized sbs. If I could have only one that would be the
one I would go for. If both looks get their own strong following then it might
be advisable to have an admin setting in the repository to choose which of the
looks to show.

The design of the diff system is such that it would be a major (and

If not color coded, perhaps adding add/change/remove markers to the _start_
of each line, since that would make JS-scripting the colorification
relatively simple? (Loop over the lines, do a regex check on the start
(change type + line number), and wrapping the affected line(s) in a styled
span.)

:-?

[Tomek Kott]

I'd be happy with Stephan's suggestion, since it would satisfy both parties
with a little work on the colorizing side. I think the only additional
point is to have the <div> or whatever surrounds the code to have a good
descriptive class we can latch on to with JS.

I wouldn't like that change very much. I think the way < and > are
used now is very intuitive, and it creates a nice separator column with
relevant meta data. I think it would be changing something which is more
intuitive to something less intuitive (for the human reader), just to
make it easier to regexp, which I don't really like.

With that being said, it's just a personal preference, and not
something I'd put up a fight against.

Though it occurs to me that if almost everyone will anyways be
sticking colorized diffs into their fossil repositories via javascript
hacks, then perhaps it should be able to output them without any
additions. :-/ When I started working on side-by-side diffs it was
suggested to me that it could be done using javascript instead, but I
thought to myself "If everyone is going to be pasting these javascripts
(or references to them) into every project they have, it's the sort of
feature fossil should handle itself.".

How much work would it be to put together a proof-of-concept sbsdiff
colorizer? (I would do it myself, but I'm sorry to say my javascript-fu
is so weak that I wouldn't even be able to assist anyone wanting to take
on the project).

The new diffs can't reliably be colored using JS because of potential

The sbs diffs come by a '<pre>' and the dump of diffs in text form,
without any browser-friendly semantic information.

I imagine that a similar look could be achieved with tags in the middle, instead
of '<pre>', and CSS. Fossil knows the semantic information of any symbol it
outputs at the time of sbs diff, and it could add or not add the tags depending
on ui or console behaviour.

Those tags could have meanings for the browser, so it could use CSS to make them
look like Richard likes, or like others may like. Would this be enough? Maybe
Richard also relies on some ability to 'copy-and-paste' that text, that thus
could be broken using the tags.

What's bad in using a combination of tags and css in the ui output? The code in
fossil looks too complex for too little win? Or simply noone wrote it still?

Lluís.

Here is an example, two different websites showing the same Fossil project
(TCL), one with the traditional colorful diff and the other with the new
retro diff:

(1) http://core.tcl.tk/tcl/ci/4ebc3a8e1e?sbs=1
(2) http://mirror1.tcl.tk/tcl/ci/4ebc3a8e1e?sbs=1&dw=67

The change of this check-in is a single line of code - indeed a single
character on that one line. With (1), my eyes are distracted by a bunch of
needless coloration, and I have to stare at the screen for a second or two
before I can discern what has actually changed. I tried using colored
diffs for a while, but I eventually gave up in frustration. They are
simply not useful to me. I can read the old-style unified diffs faster. In
(2), on the other hand, I can clearly and immediately see that one line has
changed. The change "pops" out at me. I don't have to think about it - it
is just there.

Seconded. The hidden lines receive more emphasis than the change. Do a
tkdiff on the same change and it is immediately obvious what the change is.
I checked meld, tkdiff and xxdiff and in all of them the actual character
that was removed is also highlighted making it immediately obvious what
changed. It was not immediately obvious to me what changed in either the
colored or retro examples. If fossil can't easily match the capability of
an external tool then my vote would be to go with the retro.

Fully agree, the colored one suffers from being cluttered. If the
retro one grayed
the changed line to slightly highlight it, it would help a lot.

The problem here is the violet for skipped lines that is more outstanding than the diff itself. I'm sure the colorful version can be tweaked to have the best of both world.

In my case, 80% of the case, I prefer unified (with color via JS even more). Especially when there's not a lot of changes in a line. With sbs diff, the 2 versions are far away, it' hard to see the diff. With unified, you can see right away, the 2 lines are one next to the other.

More advanced diffs programs (meld, vimdiff etc..) solve that by highlighting what is different in the line. That's become a lot more complex.

Same here. I like the colorful diff.
But I would like to know (sorry if I missed) what's the problem with color sbs and what are we getting with retro sbs?

(2) http://mirror1.tcl.tk/tcl/ci/4ebc3a8e1e?sbs=1&dw=67
The change of this check-in is a single line of code - indeed a single character on that one line. With (1), my eyes are distracted by a bunch of needless coloration, and I have to stare at the screen for a second or two before I can discern what has actually changed. I tried using colored diffs for a while, but I eventually gave up in frustration. They are simply not useful to me. I can read the old-style unified diffs faster. In (2), on the other hand, I can clearly and immediately see that one line has changed. The change "pops" out at me. I don't have to think about it - it is just there.

I'm for color-coded. All of the reasons have already been listed in the
thread.

Same here.

Here is an example, two different websites showing the same Fossil project
(TCL), one with the traditional colorful diff and the other with the new
  (1)  http://core.tcl.tk/tcl/ci/4ebc3a8e1e?sbs=1
  (2)  http://mirror1.tcl.tk/tcl/ci/4ebc3a8e1e?sbs=1&dw=67

Retro diff (2) looks really bad in Google Chrome-16 and in
Firefox-3.6.24, see attached chrome screen-shot (Ubuntu-10.04).

Huh. On Ubuntu 11.10 running the latest Firefox sources (compiled just
this morning) it looks fine: Loading Image...

Can anybody explain the difference? Is there something wrong with the CSS?

I played a bit with Firefox-10 on Linux. I seem to get a good layout
when set font-sizes in Preferences to 12pt.
When, on the other hand, I increase font sizes to 16 or 18pt then the
layout got messed up.
I am using hi-res monitor and 12pt is really small. I know very little
about CSS. Is it possible to make a layout that does not break when a
user changes default font size??

But I would like to know (sorry if I missed) what's th eproblem with color sbs and what are we getting with retro sbs?

The reason is that we have two different places in the code which do
the same thing (create side-by-side diffs), but they do it in different
ways.

Having them consolidated has benefits. (Smaller binary, much easier
to maintain, adding/changing features only requires it to be done in one
place, etc). The original sbsdiff was hard-coded for html (it will not
translate to the console), the retro sbsdiff works for both console and
displaying it in a <pre> html-section.
