2020-09-01git.txt: correct stale 'GIT_EXTERNAL_DIFF' descriptionLibravatar Philippe Blain1-1/+2
In fde97d8ac6 (Update documentation to remove incorrect GIT_DIFF_OPTS example., 2006-11-27), the description of the 'GIT_EXTERNAL_DIFF' variable was moved from 'diff-format.txt' to 'git.txt', and the documentation was updated to remove a 'diff(1)' invocation since Git did not use an external diff program anymore by default. However, the description of 'GIT_EXTERNAL_DIFF' still mentions "instead of the diff invocation described above", which is confusing. Correct that outdated sentence. Also, link to git(1) in 'diff-generate-patch.txt' when GIT_DIFF_OPTS and GIT_EXTERNAL_DIFF are mentioned, so that users can easily know what these variables are about.

2019-09-17diff, log doc: say "patch text" instead of "patches"Libravatar Johannes Sixt1-8/+12
diff, log doc: say "patch text" instead of "patches" A poster on Stackoverflow was confused that the documentation of git-log promised to generate "patches" or "patch files" with -p, but there were none to be found. Rewrite the corresponding paragraph to talk about "patch text" to avoid the confusion. Shorten the language to say "X does Y" in place of "X does not Z, but Y". Cross-reference the referred-to commands like the rest of the file does. Enumerate git-show because it includes the description as well. Mention porcelain commands before plumbing commands because I guess that the paragraph is read more frequently in their context.

2019-02-07log,diff-tree: add --combined-all-paths optionLibravatar Elijah Newren1-0/+13
The combined diff format for merges will only list one filename, even if rename or copy detection is active. For example, with raw format one might see: ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM describe.c ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM bar.sh ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR phooey.c This doesn't let us know what the original name of bar.sh was in the first parent, and doesn't let us know what either of the original names of phooey.c were in either of the parents. In contrast, for non-merge commits, raw format does provide original filenames (and a rename score to boot). In order to also provide original filenames for merge commits, add a --combined-all-paths option (which must be used with either -c or --cc, and is likely only useful with rename or copy detection active) so that we can print tab-separated filenames when renames are involved. This transforms the above output to: ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM desc.c desc.c desc.c ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM foo.sh bar.sh bar.sh ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR fooey.c fuey.c phooey.c Further, in patch format, this changes the from/to headers so that instead of just having one "from" header, we get one for each parent. For example, instead of having --- a/phooey.c +++ b/phooey.c we would see --- a/fooey.c --- a/fuey.c +++ b/phooey.c Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-06-28doc: typeset long command-line options as literalLibravatar Matthieu Moy1-2/+2
Similarly to the previous commit, use backquotes instead of forward-quotes, for long options. This was obtained with: perl -pi -e "s/'(--[a-z][a-z=<>-]*)'/\`\$1\`/g" *.txt and manual tweak to remove false positive in ascii-art (o'--o'--o' to describe rewritten history).

2016-06-28doc: typeset short command-line options as literalLibravatar Matthieu Moy1-2/+2
It was common in our documentation to surround short option names with forward quotes, which renders as italic in HTML. Instead, use backquotes which renders as monospace. This is one more step toward conformance to Documentation/CodingGuidelines.

2016-06-08doc: more consistency in environment variables formatLibravatar Tom Russello1-1/+1
Wrap with backticks (monospaced font) unwrapped or single-quotes wrapped (italic type) environment variables which are followed by the word "environment". It was obtained with: perl -pi -e "s/\'?(\\\$?[0-9A-Z\_]+)\'?(?= environment ?)/\`\1\`/g" *.txt One of the main purposes is to stick to the CodingGuidelines as possible so that people writting new documentation by mimicking the existing are more likely to have it right (even if they didn't read the CodingGuidelines).

2015-05-12doc: fix misrendering due to `single quote'Libravatar Jeff King1-1/+1
AsciiDoc misparses some text that contains a `literal` word followed by a fancy `single quote' word, and treats everything from the start of the literal to the end of the quote as a single-quoted phrase. We can work around this by switching the latter to be a literal, as well. In the first case, this is perhaps what was intended anyway, as it makes us consistent with the the earlier literals in the same paragraph. In the second, the output is arguably better, as we will format our commit references as <code> blocks. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-04-26docs: stop using asciidoc no-inline-literalLibravatar Jeff King1-1/+1
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.

2011-03-08diff format documentation: clarify --cc and -cLibravatar Adam Monsen1-4/+7
The description was unclear if -c or --cc was the default (--cc is for some commands), and incorrectly implied that the default applies to all the diff generating commands. Most importantly, "log" does not default to "--cc" (it defaults to "--no-merges") and "log -p" obeys the user's wish to see non-combined format. Only "diff" (during merge and three-blob comparison) and "show" use --cc as the default. Signed-off-by: Adam Monsen <haircut@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-02-12git log -p -m: document -m and honor --first-parentLibravatar Petr Baudis1-1/+2
git log -p -m is used to show one merge entry per parent, with an appropriate diff; this can be useful when examining histories where full set of changes introduced by a merged branch is interesting, not only the conflicts. This patch properly documents the -m switch, which has so far been mentioned only as a fairly special diff-tree flag. It also makes the code show full patch entry only for the first parent when --first-parent is used. Thus: git log -p -m --first-parent will show the history from the "main branch perspective", while also including full diff of changes introduced by other merged in branches.
