2013-06-17rev-parse: add --prefix optionLibravatar John Keeping1-0/+16
This makes 'git rev-parse' behave as if it were invoked from the specified subdirectory of a repository, with the difference that any file paths which it prints are prefixed with the full path from the top of the working tree. This is useful for shell scripts where we may want to cd to the top of the working tree but need to handle relative paths given by the user on the command line.

2013-04-02rev-parse: clarify documentation for the --verify optionLibravatar Michael Haggerty1-4/+15
The old version could be read to mean that the argument has to refer to a valid object, but that is incorrect: * the object is not necessarily read (e.g., to check for corruption) * if the argument is a 40-digit string of hex digits, then it is accepted whether or not is is the name of an existing object. So reword the explanation to be less ambiguous. Also fix the examples involving --verify: to be sure that the argument refers to a commit (rather than some other kind of object), the argument has to be suffixed with "^{commit}". This trick is not possible in the example involving --default, so don't imply that it is exactly the same as the previous example.

2012-05-18rev-parse doc: --git-dir does not always show a relative pathLibravatar Jon Seymour1-1/+2
The description was misleading because it lead the reader to believe that --git-dir would always show a relative path when, in fact, the actual behaviour does not guarantee this. Rather, it was intended that the advice be given that if a relative path is shown, then the path is relative to the current working directory and not some other directory (for example, the root of the working tree).

2012-04-26docs: stop using asciidoc no-inline-literalLibravatar Jeff King1-4/+3
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.

2011-07-06Documentation: use [verse] for SYNOPSIS sectionsLibravatar Martin von Zweigbergk1-0/+1
The SYNOPSIS sections of most commands that span several lines already use [verse] to retain line breaks. Most commands that don't span several lines seem not to use [verse]. In the HTML output, [verse] does not only preserve line breaks, but also makes the section indented, which causes a slight inconsistency between commands that use [verse] and those that don't. Use [verse] in all SYNOPSIS sections for consistency. Also remove the blank lines from git-fetch.txt and git-rebase.txt to align with the other man pages. In the case of git-rebase.txt, which already uses [verse], the blank line makes the [verse] not apply to the last line, so removing the blank line also makes the formatting within the document more consistent. While at it, add single quotes to 'git cvsimport' for consistency with other commands.

2011-03-11doc: drop author/documentation sections from most pagesLibravatar Jeff King1-10/+0
The point of these sections is generally to: 1. Give credit where it is due. 2. Give the reader an idea of where to ask questions or file bug reports. But they don't do a good job of either case. For (1), they are out of date and incomplete. A much more accurate answer can be gotten through shortlog or blame. For (2), the correct contact point is generally git@vger, and even if you wanted to cc the contact point, the out-of-date and incomplete fields mean you're likely sending to somebody useless. So let's drop the fields entirely from all manpages except git(1) itself. We already point people to the mailing list for bug reports there, and we can update the Authors section to give credit to the major contributors and point to shortlog and blame for more information. Each page has a "This is part of git" footer, so people can follow that to the main git manpage.

2010-08-02Documentation/rev-parse: quoting is required with --parseoptLibravatar Thomas Rast1-2/+5
When calling rev-parse --parseopt, as in the (now fixed) documented example eval "$(echo "$OPTS_SPEC" | git rev-parse --parseopt -- "$@" || echo exit $?)" the outermost quoting is required, as otherwise all runs of arbitrary whitespace inside the resulting 'set -- ...' call would be collapsed into a single space. This was exposed as a result of our new use of cat <<\EOF since 47e9cd2 (parseopt: wrap rev-parse --parseopt usage for eval consumption, 2010-06-12), but has always been a problem when handling arguments containing e.g. newlines.

2010-02-17docs: don't talk about $GIT_DIR/refs/ everywhereLibravatar Jeff King1-10/+12
It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we may also consult the packed refs mechanism. These days we tend to treat the "refs hierarchy" as more of an abstract namespace that happens to be represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at worst it can confuse users who then look in $GIT_DIR/refs and find that it is missing some of the refs they expected to see. This patch drops most uses of "$GIT_DIR/refs/*", changing them into just "refs/*", under the assumption that users can handle the concept of an abstract refs namespace. There are a few things to note: - most cases just dropped the $GIT_DIR/ portion. But for cases where that left _just_ the word "refs", I changed it to "refs/" to help indicate that it was a hierarchy. I didn't do the same for longer paths (e.g., "refs/heads" remained, instead of becoming "refs/heads/"). - in some cases, no change was made, as the text was explicitly about unpacked refs (e.g., the discussion in git-pack-refs). - In some cases it made sense instead to note the existence of packed refs (e.g., in check-ref-format and rev-parse).

2010-01-10Documentation: spell 'git cmd' without dash throughoutLibravatar Thomas Rast1-17/+17
The documentation was quite inconsistent when spelling 'git cmd' if it only refers to the program, not to some specific invocation syntax: both 'git-cmd' and 'git cmd' spellings exist. The current trend goes towards dashless forms, and there is precedent in 647ac70 (git-svn.txt: stop using dash-form of commands., 2009-07-07) to actively eliminate the dashed variants. Replace 'git-cmd' with 'git cmd' throughout, except where git-shell, git-cvsserver, git-upload-pack, git-receive-pack, and git-upload-archive are concerned, because those really live in the $PATH.

These double quotes do not work if present in the described config value, so drop them. git-checkout.txt Change "`...`" to `...` or `"..."`. All instances are command line argument examples. One "`-`" becomes `-`. Two others are involve curly braces, so move the double quotes inside the literal region to indicate that they might need to be quoted on the command line of certain shells (tcsh). git-merge.txt Change "`...`" to `...`. All instances are used to describe merge conflict markers. The quotes should are not important. git-rev-parse.txt Change "`...`" to `...`. All instances are around command line arguments where no in-shell quoting should be necessary. gitcli.txt Change `"..."` to `...`. All instances are around command line examples or single command arguments. They do not semanticly belong inside the literal text, and they are not needed outside it. glossary-content.txt user-manual.txt Change "`...`" to `...`. All instances were around command lines.
