* help.c::uniq: plug a leakJeff King2012-07-251-2/+5
| | | | | | | | | | | | | | | | | We observe that the j-1 element can serve the same purpose as the i-1 element that we use in the strcmp(); it is either: 1. Exactly i-1, when the loop begins (and until we see a duplicate). 2. The same pointer that was stored at i-1 (if it was not a duplicate, and we just copied it into place). 3. A pointer to an equivalent string (i.e., we rejected i-1 _because_ it was identical to j-1).

* Reduce cost of deletion in levenstein distance (4 -> 3)Matthieu Moy2012-05-291-1/+1
| | | | | | | | | | | | | | Before this patch, a character deletion has the same cost as 2 swaps, or 4 additions, so Git prefers suggesting a completely scrambled command name to removing a character. For example, "git tags" suggests "stage", but not "tag". By setting the deletion cost to 3, we keep it higher than swaps or additions, but prefer 1 deletion to 2 swaps. "git tags" now suggests "tag" in addition to staged. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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...

* pager: find out the terminal width before spawning the pagerzj/term-columnsZbigniew Jędrzejewski-Szmek2012-02-131-22/+0
| | | | | | | | | | | | | | | | term_columns() checks for terminal width via ioctl(2) on the standard output, but we spawn the pager too early for this check to be useful. The effect of this buglet can be observed by opening a wide terminal and running "git -p help --all", which still shows 80-column output, while "git help --all" uses the full terminal width. Run the check before we spawn the pager to fix this. While at it, move term_columns() to pager.c and export it from cache.h so that callers other than the help subsystem can use it.

* | help.c: Fix detection of custom merge strategy on cygwinRamsay Jones2011-06-161-1/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test t7606-merge-custom.sh fails on cygwin when git-merge fails with an "Could not find merge strategy 'theirs'" error, despite the test correctly preparing an (executable) git-merge-theirs script. The cause of the failure is the mis-detection of the executable status of the script, by the is_executable() function, while the load_command_list() function is searching the path for additional merge strategy programs. Note that the l/stat() "functions" on cygwin are somewhat schizophrenic (see commits adbc0b6, 7faee6b and 7974843), and their behaviour depends on the timing of various git setup and config function calls. In particular, until the "git_dir" has been set (have_git_dir() returns true), the real cygwin (POSIX emulating) l/stat() functions are called. Once "git_dir" has been set, the "native Win32 API" implementations of l/stat() may, or may not, be called depending on the setting of the core.filemode and core.ignorecygwinfstricks config variables. We also note that, since commit c869753, core.filemode is forced to false, even on NTFS, by git-init and git-clone. A user (or a test) can, of course, reset core.filemode to true explicitly if the filesystem supports it (and he doesn't use any problematic windows software). The test-suite currently runs all tests on cygwin with core.filemode set to false. Given the above, we see that the built-in merge strategies are correctly detected as executable, since they are checked for before "git_dir" is set, whereas all custom merge strategies are not, since they are checked for after "git_dir" is set. In order to fix the mis-detection problem, we change the code in is_executable() to re-use the conditional WIN32 code section, which actually looks at the content of the file to determine if the file is executable. On cygwin we also make the additional code conditional on the executable bit of the file mode returned by the initial stat() call. (only the real cygwin function would set the executable bit in the file mode.) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* help: always suggest common-cmds if prefix of cmdErik Faye-Lund2010-12-051-8/+39
| | | | | | | | | | | | | | If someone runs "git st", the command "git status" is not suggested because it's not one of the closest levenshtein-neighbour. Reserve the distance of 0 for common commands where the entered command is a prefixe, as these are often more likely to be what the user meant. This way, "git status" is the first suggestion, while a list of possible typos are still suggested as well.

| | | | | | | | | | | | | | | | | | | | | | If a given command is not found, then help.c tries to guess which one the user could have meant. If help.autocorrect is 0 or unset, then a list of suggestions is given as long as the dissimilarity between the given command and the candidates is not excessively high. But if help.autocorrect was non-zero (i.e., a delay after which the command is run automatically), the latter restriction on dissimilarity was not obeyed. In my case, this happened: $ git ..daab02 WARNING: You called a Git command named '..daab02', which does not exist.

Avoiding MSYS' bash when possible is good because it avoids potential path translation issues. In this case it is not too hard to avoid launching a shell, so let's avoid it. The Windows-specific code is implemented in compat/mingw.c to avoid platform-specific code in the main code base. On Windows, open_html is provided as a define. If open_html is not defined, git-web--browse is used. This approach avoids platform-specific ifdefs by using per-function ifdefs. The "ifndef open_html" together with the introductory comment should sufficiently warn developers, so that they hopefully will not break this mechanism.

On Windows it failed for two reasons: - The PATH separator is ';', not ':' on Windows. - stat() does not set the executable bit. We now open the file and guess whether it is executable. The result of the guess is good enough for the list of git commands, but it is of no use for a general stat() implementation because (1) it is a guess, (2) the user has no way to influence the outcome (via chmod or similar), and (3) it would reduce stat() performance by an unacceptable amount.

| | | | | | | | | | | | | | | | | | | | Currently "git help -m GITCMD" is restricted to a set of man viewers defined at compile time. You can subvert the "man.<tool>.path" to force "git help -m" to use a different man, viewer, but if you have a man viewer whose invocation syntax does not match one of the current tools then you would have to write a wrapper script for it. This patch adds a git config variable "man.<tool>.cmd" which allows a more flexible man viewer choice. If you run "git help -m GITCMD" with the "man.viewer" config variable set to an unrecognized tool then it will query the "man.<tool>.cmd" config variable. If this variable exists, then the specified tool will be treated as a custom man viewer and it will be run in a shell with the man page name of the GITCMD added as extra parameter.

| | | | | | | | | | | | | | | | | | This allows multiple viewer candidates to be listed in the configuration file, like this: [man] viewer = woman viewer = konqueror viewer = man The candidates are tried in the order listed in the configuration file, and the first suitable one (e.g. konqueror cannot be used outside windowed environment) is used.

* help: add "man.viewer" config var to use "woman" or "konqueror"Christian Couder2008-03-111-1/+80
| | | | | | | | | | | | | This patch makes it possible to view man pages using other tools than the "man" program. It also implements support for emacs' "woman" and konqueror with the man KIO slave to view man pages. Note that "emacsclient" is used with option "-e" to launch "woman" on emacs and this works only on versions >= 22.

* help: respect aliasesJeff King2008-02-241-1/+32
| | | | | | | | | | | | | | If we have an alias "foo" defined, then the help text for "foo" (via "git help foo" or "git foo --help") now shows the definition of the alias. Before showing an alias definition, we make sure that there is no git command which would override the alias (so that even though you may have a "log" alias, even though it will not work, we don't want to it supersede "git help log").

* help: use parseoptJeff King2008-02-241-64/+59
| | | | | | | | | | | | | This patch converts cmd_help to use parseopt, along with a few style cleanups, including: - enum constants are now ALL_CAPS - parse_help_format returns an enum value rather than setting a global as a side effect Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
