The highlightning of combined diffs is currently disabled. This is
because output from a combined diff is much harder to highlight because
it is not obvious which removed and added lines should be compared.
Current code requires that the number of added lines is equal to the
number of removed lines and only skips first +/- character, treating
second +/- as a line content, Thus, it is not possible to simply use
existing algorithm unchanged for combined diffs.
Let's start with a simple case: only highlight changes that come from
one parent, i.e. when every removed line has a corresponding added line
for the same parent. This way the highlightning cannot get wrong. For
example, following diffs would be highlighted:
- removed line for first parent
+ added line for first parent
context line
-removed line for second parent
+added line for second parent
or
- removed line for first parent
-removed line for second parent
+ added line for first parent
+added line for second parent
but following output will not:
- removed line for first parent
-removed line for second parent
+added line for second parent
++added line for both parents
In other words, we require that pattern of '-'-es in pre-image matches
pattern of '+'-es in post-image.
Further changes may introduce more intelligent approach that better
handles combined diffs.

Reading diff output is sometimes very hard, even if it's colored,
especially if lines differ only in few characters. This is often true
when a commit fixes a typo or renames some variables or functions.
This commit teaches gitweb to highlight characters that are different
between old and new line with a light green/red background. This should
work in the similar manner as in Trac or GitHub.
The algorithm that compares lines is based on contrib/diff-highlight.
Basically, it works by determining common prefix/suffix of corresponding
lines and highlightning only the middle part of lines. For more
information, see contrib/diff-highlight/README.
Combined diffs are not supported but a following commit will change it.
Since we need to pass esc_html()'ed or esc_html_hl_regions()'ed lines to
format_diff_lines(), so it was taught to accept preformatted lines
passed as a reference.

Now lines are formatted closer to place where we actually use HTML
formatted output.
This means that we put raw lines in the @chunk accumulator, rather than
formatted lines. Because we still need to know class (type) of line
when accumulating data to post-process and print, process_diff_line()
subroutine was retired and replaced by diff_line_class() used in
git_patchset_body() and new restructured format_diff_line() used in
print_diff_chunk().
As a side effect, we have to pass \%from and \%to down to callstack.
This is a preparation patch for diff refinement highlightning. It's not
meant to change gitweb output.

This renames print_sidebyside_diff_chunk() to print_diff_chunk() and
makes use of it for both side-by-side and inline diffs. Now diff lines
are always accumulated before they are printed. This opens the
possibility to preprocess diff output before it's printed, which is
needed for diff refinement highlightning (implemented in incoming
patches).
If print_diff_chunk() was left as is, the new function
print_inline_diff_lines() could reorder diff lines. It first prints all
context lines, then all removed lines and finally all added lines. If
the diff output consisted of mixed added and removed lines, gitweb would
reorder these lines. This is true for combined diff output, for
example:
- removed line for first parent
+ added line for first parent
-removed line for second parent
++added line for both parents
would be rendered as:
- removed line for first parent
-removed line for second parent
+ added line for first parent
++added line for both parents
To prevent gitweb from reordering lines, print_diff_chunk() calls
print_diff_lines() as soon as it detects that both added and removed
lines are present and there was a class change, and at the end of chunk.

Currently, print_sidebyside_diff_chunk() does two things: it
accumulates diff lines and prints them. Accumulation may be used to
perform additional operations on diff lines, so it makes sense to split
these two things. Thus, whole code that formats and prints diff lines
in the 'side-by-side' manner is moved out of print_sidebyside_diff_chunk()
to a separate subroutine and two conditions that control printing
diff liens are merged.
Thanks to that, we can easily (in later patches) replace call to that
subroutine with a call to more generic print_diff_lines() that will
control whether 'inline' or 'side-by-side' diff should be printed.
As a side effect, context lines are printed just before printing added
and removed lines, and at the end of chunk (previously, they were
printed immediately on the class change). However, this doesn't change
gitweb output.
The outcome of this patch is that print_sidebyside_diff_chunk() is now
much shorter and easier to read.
While at it, drop the '# assume that it is change' comment. According
to Jakub Narębski:
What I meant here when I was writing it that they are lines that
changed between two versions, like '!' in original (not unified)
context format.
We can omit this comment.

With this change, esc_html_hl_regions() accepts options and passes them
down to esc_html(). This may be needed if a caller wants to pass
-nbsp=>1 to esc_html().
The idea and implementation example of this change was described in
337da8d2 (gitweb: Introduce esc_html_match_hl and esc_html_hl_regions,
2012-02-27). While other suggestions may be more useful in some cases,
there is no need to implement them at the moment. The
esc_html_hl_regions() interface may be changed later if it's needed.

Previously GIT_EDITOR was not listed in git(1) "Environment Variables" section,
which could be very confusing to users. Include it in "other" subsection along
with a link to git-var(1), since that is the page that fully describes all
places where editor can be set and also their preference order.
Also, git-var(1) did not say that hardcoded fallback 'vi' may have been changed
at build time. A user could be puzzled if 'nano' pops up even when none of the
mentioned environment vars or config.editor are set. Clarify this.
Ideally, the build system should be changed to reflect the chosen fallback
editor when creating the man pages. Not sure if that is even possible though.

Sometimes one wants to see the different between two commits that are
a long distance apart in the graph display. This is difficult to do
with the "Diff this -> selected" and "Diff selected -> this" menu
items because the need to maintain the selection means that one can't
use the find facilities or the reference list window to navigate from
one to the other.
This provides an alternative using the mark. Having found one commit,
one marks it with the "Mark this commit" menu item, then navigates to
the other commit and uses the new "Diff this -> marked commit" and/or
"Diff marked commit -> this" menu items.

noticeable time (several seconds) for gitk to resolve short SHA1 IDs

The following only concerns systems using X and the client-side font
rendering framework from freedesktop.org. Windows and Mac OS X are
not affected.
Starting with version 8.5, Tk uses freetype and fontconfig by default
to render fonts on platforms that support it. Gitk currently defaults
to the font Helvetica for the interface and Courier for diffs, and
both unfortunately look rather bad on screen in the default
configuration on many Linux distros with anti-aliasing and poor
hinting.
It is better to default to "sans" and "monospace", which are mapped by
fontconfig to some appropriate font of the sysadmin and user's
choosing (typically Bitstream Vera Sans and Mono). The result looks
more sensible and it makes gitk feel like a well-behaved software
citizen since its fonts match other native apps.
This patch does not change the appearance of gitk for users that have
already run it, since gitk uses the remembered UI and diff font names
from ~/.gitk.

Automake's contribution guidelines suggest using "git describe" output
in commit logs to reference previous commits. By contrast, in
coreutils, I had acquired the habit of using a bare SHA1 prefix (8 hex
digits), since gitk creates clickable links for that, and not for "git
describe" output.
I prefer the readability of the full "git describe" output, yet want
to retain the gitk links, so this renders as clickable not just
SHA1-like strings, but also an SHA1-like string that is prefixed by
"-g".

Launching 'gitk -- .' or 'gitk -- ..\t' restricts the display to files
under the given directory but the file list is left empty. This is because
the path_filter function fails to match the filenames which are relative
to the working tree to the filter which is filessytem relative.
This solves the problem by making both names fully qualified filesystem
paths before performing the comparison.
