2015-01-14standardize usage info string formatLibravatar Alex Henrie1-1/+1
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-12-22Merge branch 'jc/exec-cmd-system-path-leak-fix'Libravatar Junio C Hamano1-2/+7
The function sometimes returned a non-freeable memory and some other times returned a piece of memory that must be freed. * jc/exec-cmd-system-path-leak-fix: system_path(): always return free'able memory to the caller
2014-11-30system_path(): always return free'able memory to the callerLibravatar Junio C Hamano1-2/+7
The function sometimes returns a newly allocated string and sometimes returns a borrowed string, the latter of which the callers must not free(). The existing callers all assume that the return value belongs to the callee and most of them copy it with strdup() when they want to keep it around. They end up leaking the returned copy when the callee returned a new string because they cannot tell if they should free it. Change the contract between the callers and system_path() to make the returned string owned by the callers; they are responsible for freeing it when done, but they do not have to make their own copy to store it away. Adjust the callers to make sure they do not leak the returned string once they are done, but do not bother freeing it just before dying, exiting or exec'ing other program to avoid unnecessary churn.

2014-10-10doc: add 'everyday' to 'git help'Libravatar Philip Oakley1-0/+1
The "Everyday GIT With 20 Commands Or So" is not accessible via the Git help system. Move everyday.txt to giteveryday.txt so that "git help everyday" works, and create a new placeholder file everyday.html to refer people who follow existing URLs to the updated location. giteveryday.txt now formats well with AsciiDoc as a man page and refreshed content to a more command modern style. Add 'everyday' to the help --guides list and update git(1) and 5 other links to giteveryday. Signed-off-by: Philip Oakley <philipoakley@iee.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-08-20run-command: introduce CHILD_PROCESS_INITLibravatar René Scharfe1-2/+1
Most struct child_process variables are cleared using memset first after declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to initialize them statically instead. That's shorter, doesn't require a function call and is slightly more readable (especially given that we already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Libravatar Christian Couder1-4/+4
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.

2013-04-02builtin/help.c: split "-a" processing into twoLibravatar Philip Oakley1-1/+7
"help -a" (help all) gives the list of available commands and then further gives hints on the use of "git help". Separate these into two steps, because we will add "help -g" (help guides) that want to also show the overall hints after it is done. While at it, change the definition of the "-a" option to use OPT_BOOL, not the deprecated OPT_BOOLEAN. We do not behave differently when the user gives the "-a" option multiple times, e.g. "git help -a -a".

"git help -w $cmd" can show HTML version of documentation for "git-$cmd" by setting help.htmlpath to somewhere other than the default location where the build procedure installs them locally; the variable can even point at a http:// URL. * cw/help-over-network: Allow help.htmlpath to be a URL prefix Add config variable to set HTML path for git-help --web

Setting this to a URL prefix instead of a path to a local directory allows git-help --web to work even when HTML docs aren't locally installed, by pointing the browser at a copy accessible on the web.

2012-04-25help: replace underlining "help -a" headers using hyphens with a blank lineLibravatar Nguyễn Thái Ngọc Duy1-1/+1
We used to underline a header text, like this: This is a header ---------------- content... But calculating text length so that the dashes align with the text could get complicated because the text could be in any charset in translated Git. There is no point to use this pseudo underline; simply a blank line would do and it even makes it easier to read: This is a header content...

2010-05-31enums: omit trailing comma for portabilityLibravatar Gary V. Vaughan1-1/+1
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLibravatar Linus Torvalds1-0/+466
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
