* jj/doc-markup-hints-in-coding-guidelines: State correct usage of literal examples in man pages in the coding standards
2013-11-18State correct usage of literal examples in man pages in the coding standardsLibravatar Jason St. John1-3/+31
The man pages contain inconsistent usage of backticks vs. single quotes around options, commands, etc. that are in paragraphs. This commit states that backticks should always be used around literal examples. This commit states that "--" and friends should not be escaped (e.g. use `--pretty=oneline` instead of `\--pretty=oneline`). This commit also states correct usage for typesetting command usage examples with inline substitutions.

2013-02-01Documentation: avoid poor-man's small caps GITLibravatar Thomas Ackermann1-0/+5
In the earlier days, we used to spell the name of the system as GIT, to simulate as if it were typeset with capital G and IT in small caps. Later we stopped doing so at around 1.6.5 days. Let's stop doing so throughout the documentation. The name to refer to the whole system (and the concept it embodies) is "Git"; the command end-users type is "git". And document this in the coding guideline. Signed-off-by: Thomas Ackermann <th.acker@arcor.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-01-30CodingGuidelines: add Python coding guidelinesLibravatar John Keeping1-0/+14
These are kept short by simply deferring to PEP-8. Most of the Python code in Git is already very close to this style (some things in contrib/ are not). Rationale for version suggestions: - Amongst the noise in [1], there isn't any disagreement about using 2.6 as a base (see also [2]), although Brandon Casey recently added support for 2.4 and 2.5 to git-p4 [3]. - Restricting ourselves to 2.6+ makes aiming for Python 3 compatibility significantly easier [4]. - Advocating Python 3 support in all scripts is currently unrealistic because: - 'p4 -G' provides output in a format that is very hard to use with Python 3 (and its documentation claims Python 3 is unsupported). - Mercurial does not support Python 3. - Bazaar does not support Python 3. - But we should try to make new scripts compatible with Python 3 because all new Python development is happening on version 3 and the Python community will eventually stop supporting Python 2 [5]. - Python 3.1 is required to support the 'surrogateescape' error handler for encoding/decodng filenames to/from Unicode strings and Python 3.0 is not longer supported.

2012-08-15Documentation/CodingGuidelines: spell out more shell guidelinesLibravatar Heiko Voigt1-0/+8
In earlier days, "imitate the style in the neibouring code" was sufficient to keep the coherent style, but over time some parts of the codebase have drifted enough to make it ineffective.

2012-02-27CodingGuidelines: do not use 'which' in shell scriptsLibravatar Tim Henigan1-0/+5
During the code review of a recent patch, it was noted that shell scripts must not use 'which $cmd' to check the availability of the command $cmd. The output of the command is not machine parseable and its exit code is not reliable across platforms. It is better to use 'type' to accomplish this task.

2011-12-05i18n: add infrastructure for translating Git with gettextLibravatar Ævar Arnfjörð Bjarmason1-0/+7
Change the skeleton implementation of i18n in Git to one that can show localized strings to users for our C, Shell and Perl programs using either GNU libintl or the Solaris gettext implementation. This new internationalization support is enabled by default. If gettext isn't available, or if Git is compiled with NO_GETTEXT=YesPlease, Git falls back on its current behavior of showing interface messages in English. When using the autoconf script we'll auto-detect if the gettext libraries are installed and act appropriately. This change is somewhat large because as well as adding a C, Shell and Perl i18n interface we're adding a lot of tests for them, and for those tests to work we need a skeleton PO file to actually test translations. A minimal Icelandic translation is included for this purpose. Icelandic includes multi-byte characters which makes it easy to test various edge cases, and it's a language I happen to understand. The rest of the commit message goes into detail about various sub-parts of this commit. = Installation Gettext .mo files will be installed and looked for in the standard $(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to override that, but that's only intended to be used to test Git itself. = Perl Perl code that's to be localized should use the new Git::I18n module. It imports a __ function into the caller's package by default. Instead of using the high level Locale::TextDomain interface I've opted to use the low-level (equivalent to the C interface) Locale::Messages module, which Locale::TextDomain itself uses. Locale::TextDomain does a lot of redundant work we don't need, and some of it would potentially introduce bugs. It tries to set the $TEXTDOMAIN based on package of the caller, and has its own hardcoded paths where it'll search for messages. I found it easier just to completely avoid it rather than try to circumvent its behavior. In any case, this is an issue wholly internal Git::I18N. Its guts can be changed later if that's deemed necessary. See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for a further elaboration on this topic. = Shell Shell code that's to be localized should use the git-sh-i18n library. It's basically just a wrapper for the system's gettext.sh. If gettext.sh isn't available we'll fall back on gettext(1) if it's available. The latter is available without the former on Solaris, which has its own non-GNU gettext implementation. We also need to emulate eval_gettext() there. If neither are present we'll use a dumb printf(1) fall-through wrapper. = About libcharset.h and langinfo.h We use libcharset to query the character set of the current locale if it's available. I.e. we'll use it instead of nl_langinfo if HAVE_LIBCHARSET_H is set. The GNU gettext manual recommends using langinfo.h's nl_langinfo(CODESET) to acquire the current character set, but on systems that have libcharset.h's locale_charset() using the latter is either saner, or the only option on those systems. GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either, but MinGW and some others need to use libcharset.h's locale_charset() instead. =Credits This patch is based on work by Jeff Epler <jepler@unpythonic.net> who did the initial Makefile / C work, and a lot of comments from the Git mailing list, including Jonathan Nieder, Jakub Narebski, Johannes Sixt, Erik Faye-Lund, Peter Krefting, Junio C Hamano, Thomas Rast and others.

2010-09-27CodingGuidelines: spell Arithmetic Expansion with $(($var))Libravatar Junio C Hamano1-0/+4
POSIX wants shells to support both "N" and "$N" and requires them to yield the same answer to $((N)) and $(($N)), but we should aim for portability in a case like this, especially when the price we pay to do so is so small, i.e. a few extra dollars. Signed-off-by: Junio C Hamano <gitster@pobox.com>
