In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

: This breaks tests. Perhaps it is not worth using the decimal-width stuff
: for this series, at least initially.
diff --stat: add config option to limit graph width
diff --stat: enable limiting of the graph part
diff --stat: add a test for output with COLUMNS=40
diff --stat: use a maximum of 5/8 for the filename part
merge --stat: use the full terminal width

Config option diff.statGraphWidth=<width> is equivalent to
--stat-graph-width=<width>, except that the config option is ignored
by format-patch.
For the graph-width limiting to be usable, it should happen
'automatically' once configured, hence the config option.
Nevertheless, graph width limiting only makes sense when used on a
wide terminal, so it should not influence the output of format-patch,
which adheres to the 80-column standard.

A new option --stat-graph-width=<width> can be used to limit the width
of the graph part even is more space is available. Up to <width>
columns will be used for the graph.
If commits changing a lot of lines are displayed in a wide terminal
window (200 or more columns), and the +- graph uses the full width,
the output can be hard to comfortably scan with a horizontal movement
of human eyes. Messages wrapped to about 80 columns would be
interspersed with very long +- lines. It makes sense to limit the
width of the graph part to a fixed value (e.g. 70 columns), even if
more columns are available.

The way that available columns are divided between the filename part
and the graph part is modified to use as many columns as necessary for
the filenames and the rest for the graph.
If there isn't enough columns to print both the filename and the
graph, at least 5/8 of available space is devoted to filenames. On a
standard 80 column terminal, or if not connected to a terminal and
using the default of 80 columns, this gives the same partition as
before.
The effect of this change is visible in the patch to the test vector
in t4052; with a small change with long filename, it stops truncating
the name part too short, and also allocates a bit more columns to the
graph for larger changes.

Add the option -W/--function-context to git diff. It is similar to
the same option of git grep and expands the context of change hunks
so that the whole surrounding function is shown. This "natural"
context can allow changes to be understood better.
Note: GNU patch doesn't like diffs generated with the new option;
it seems to expect context lines to be the same before and after
changes. git apply doesn't complain.
This implementation has the same shortcoming as the one in grep,
namely that there is no way to explicitly find the end of a
function. That means that a few lines of extra context are shown,
right up to the next recognized function begins. It's already
useful in its current form, though.
The function get_func_line() in xdiff/xemit.c is extended to work
forward as well as backward to find post-context as well as
pre-context. It returns the position of the first found matching
line. The func_line parameter is made optional, as we don't need
it for -W.
The enhanced function is then used in xdl_emit_diff() to extend
the context as needed. If the added context overlaps with the
next change, it is merged into the current hunk.

* jh/dirstat-lines:
Mark dirstat error messages for translation
Improve error handling when parsing dirstat parameters
New --dirstat=lines mode, doing dirstat analysis based on diffstat
Allow specifying --dirstat cut-off percentage as a floating point number
Add config variable for specifying default --dirstat behavior
Refactor --dirstat parsing; deprecate --cumulative and --dirstat-by-file
Make --dirstat=0 output directories that contribute < 0.1% of changes
Add several testcases for --dirstat and friends
This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.
The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).
For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.
In linux-2.6.git, running the three different --dirstat modes:
time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null
yields the following average runtimes on my machine:
- "changes" (default): ~6.0 s
- "lines": ~9.6 s
- "files": ~0.1 s
So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.
The patch also includes documentation and tests for the new dirstat mode.

Currently, the --dirstat analysis ignores when lines within a file are
rearranged, because the "damage" calculated by show_dirstat() is 0.
However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.
Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.
Also, skip --dirstat analysis when the object names are the same (e.g. for
a pure file rename).

Teach "-G<regexp>" that is similar to "-S<regexp> --pickaxe-regexp" to the
"git diff" family of commands. This limits the diff queue to filepairs
whose patch text actually has an added or a deleted line that matches the
given regexp. Unlike "-S<regexp>", changing other parts of the line that
has a substring that matches the given regexp IS counted as a change, as
such a change would appear as one deletion followed by one addition in a
patch text.
Unlike -S (pickaxe) that is intended to be used to quickly detect a commit
that changes the number of occurrences of hits between the preimage and
the postimage to serve as a part of larger toolchain, this is meant to be
used as the top-level Porcelain feature.
The implementation unfortunately has to run "diff" twice if you are
running "log" family of commands to produce patches in the final output
(e.g. "git log -p" or "git format-patch"). I think we _could_ cache the
result in-core if we wanted to, but that would require larger surgery to
the diffcore machinery (i.e. adding an extra pointer in the filepair
structure to keep a pointer to a strbuf around, stuff the textual diff to
the strbuf inside diffgrep_consume(), and make use of it in later stages
when it is available) and it may not be worth it.

The new "ignore" config option controls the default behavior for "git
status" and the diff family. It specifies under what circumstances they
consider submodules as modified and can be set separately for each
submodule.
The command line option "--ignore-submodules=" has been extended to accept
the new parameter "none" for both status and diff.
Users that chose submodules to get rid of long work tree scanning times
might want to set the "dirty" option for those submodules. This brings
back the pre 1.7.0 behavior, where submodule work trees were never
scanned for modifications. By using "--ignore-submodules=none" on the
command line the status and diff commands can be told to do a full scan.
This option can be set to the following values (which have the same name
and meaning as for the "--ignore-submodules" option of status and diff):
"all": All changes to the submodule will be ignored.
"dirty": Only differences of the commit recorded in the superproject and
the submodules HEAD will be considered modifications, all changes
to the work tree of the submodule will be ignored. When using this
value, the submodule will not be scanned for work tree changes at
all, leading to a performance benefit on large submodules.
"untracked": Only untracked files in the submodules work tree are ignored,
a changed HEAD and/or modified files in the submodule will mark it
as modified.
"none" (which is the default): Either untracked or modified files in a
submodules work tree or a difference between the subdmodules HEAD
and the commit recorded in the superproject will make it show up
as changed. This value is added as a new parameter for the
"--ignore-submodules" option of the diff family and "git status"
so the user can override the settings in the configuration.

Add optional parameters to the diff option "--ignore-submodules"
git diff: rename test that had a conflicting name
In some use cases it is not desirable that the diff family considers
submodules that only contain untracked content as dirty. This may happen
e.g. when the submodule is not under the developers control and not all
build generated files have been added to .gitignore by the upstream
developers. Using the "untracked" parameter for the "--ignore-submodules"
option disables checking for untracked content and lets git diff report
them as changed only when they have new commits or modified content.
Sometimes it is not wanted to have submodules show up as changed when they
just contain changes to their work tree. An example for that are scripts
which just want to check for submodule commits while ignoring any changes
to the work tree. Also users having large submodules known not to change
might want to use this option, as the - sometimes substantial - time it
takes to scan the submodule work tree(s) is saved.

- newlines in the input are output as a line consisting only of a
tilde '~'
Both of these formats still support color if it is enabled, using it

Make git-branch, git-show-branch, git-grep, and all the diff-based
programs accept an optional argument <when> for --color. The argument
is a colorbool: "always", "never", or "auto". If no argument is given,
"always" is used; --no-color is an alias for --color=never. This makes
the command-line interface consistent with other GNU tools, such as `ls'
and `grep', and with the git-config color options. Note that, without
an argument, --color and --no-color work exactly as before.
To implement this, two internal changes were made:
1. Allow the first argument of git_config_colorbool() to be NULL,
in which case it returns -1 if the argument isn't "always", "never",
or "auto".
2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb()

Jeff King recently reinstated -p to suppress the default diffstat
(as -p used to work before 68daa64, about 14 months ago).
However, -p is also needed in combination with certain options
(e.g. --stat or --numstat) in order to produce any patch at all.
The documentation does not mention this.
Since the purpose of format-patch is to produce a patch that
can be emailed, it does not make sense that certain combination
of options will suppress the generation of the patch itself.
Therefore:
* Update 'git format-patch' to always generate a patch.
* Since the --name-only, --name-status, and --check suppresses
the generation of the patch, disallow those options,
and remove the description of them in the documentation.
* Remove the reference to -p in the description of -U.

summaries inlined in the diff, instead of not-quite-helpful SHA-1 pairs.
The format imitates what "git submodule summary" shows.
To do that, <path>/.git/objects/ is added to the alternate object
databases (if that directory exists).
This option was requested by Jens Lehmann at the GitTogether in Berlin.

The existing text was very vague about what exactly it means
for difference to "contain" a change. This seems to cause
confusion on the mailing list every month or two.
To fix it we:
1. use "introduce or remove an instance of" instead of
"contain"
2. point the user to gitdiffcore(7), which contains a more
complete explanation

* js/diff-color-words:
Change the spelling of "wordregex".
color-words: Support diff.wordregex config option
color-words: make regex configurable via attributes
color-words: expand docs with precise semantics
color-words: enable REG_NEWLINE to help user
color-words: take an optional regular expression describing words
color-words: change algorithm to allow for 0-character word boundaries
color-words: refactor word splitting and use ALLOC_GROW()
Add color_fwrite_lines(), a function coloring each line individually
When diff is invoked with --color-words (w/o =regex), use the regular
expression the user has configured as diff.wordregex.
diff drivers configured via attributes take precedence over the
diff.wordregex-words setting. If the user wants to change them, they have
their own configuration variables.

Make the --color-words splitting regular expression configurable via
the diff driver's 'wordregex' attribute. The user can then set the
driver on a file in .gitattributes. If a regex is given on the
command line, it overrides the driver's setting.
We also provide built-in regexes for the languages that already had
funcname patterns, and add an appropriate diff driver entry for C/++.
(The patterns are designed to run UTF-8 sequences into a single chunk
to make sure they remain readable.)

In some applications, words are not delimited by white space. To
allow for that, you can specify a regular expression describing
what makes a word with
git diff --color-words='[A-Za-z0-9]+'
Note that words cannot contain newline characters.
As suggested by Thomas Rast, the words are the exact matches of the
regular expression.
Note that a regular expression beginning with a '^' will match only
a word at the beginning of the hunk, not a word at the beginning of
a line, and is probably not what you want.
This commit contains a quoting fix by Thomas Rast.

Merge two hunks if there is only the specified number of otherwise unshown
context between them. For --inter-hunk-context=1, the resulting patch has
the same number of lines but shows uninterrupted context instead of a
context header line in between.
Patches generated with this option are easier to read but are also more
likely to conflict if the file to be patched contains other changes.
This patch keeps the default for this option at 0. It is intended to just
make the feature available in order to see its advantages and downsides.

The new option --ignore-submodules can now be used to ignore changes in
submodules.
Why? Sometimes it is not interesting when a submodule changed.
For example, when reordering some commits in the superproject, a dirty
submodule is usually totally uninteresting. So we will use this option
in git-rebase to test for a dirty working tree.

This allows the --relative option to say which subdirectory to
pretend to be in, so that in a bare repository, you can say:

This adds --relative option to the diff family. When you start
from a subdirectory:
$ git diff --relative
shows only the diff that is inside your current subdirectory,
and without $prefix part. People who usually live in
subdirectories may like it.
There are a few things I should also mention about the change:
- This works not just with diff but also works with the log
family of commands, but the history pruning is not affected.
In other words, if you go to a subdirectory, you can say:
$ git log --relative -p
but it will show the log message even for commits that do not
touch the current directory. You can limit it by giving
pathspec yourself:
$ git log --relative -p .
This originally was not a conscious design choice, but we
have a way to affect diff pathspec and pruning pathspec
independently. IOW "git log --full-diff -p ." tells it to
prune history to commits that affect the current subdirectory
but show the changes with full context. I think it makes
more sense to leave pruning independent from --relative than
the obvious alternative of always pruning with the current
subdirectory, which would break the symmetry.
- Because this works also with the log family, you could
format-patch a single change, limiting the effect to your
subdirectory, like so:
$ cd gitk-git
$ git format-patch -1 --relative 911f1eb
But because that is a special purpose usage, this option will
never become the default, with or without repository or user
preference configuration. The risk of producing a partial
patch and sending it out by mistake is too great if we did
so.
- This is inherently incompatible with --no-index, which is a
bolted-on hack that does not have much to do with git
itself. I didn't bother checking and erroring out on the
combined use of the options, but probably I should.

This default regex now matches explicit values, and unfortunately in this
case gitlink was being matched by just 'link', causing the wrong inline
macro template to be applied. By renaming the macro, we can avoid being
matched by the wrong regex.
