See 'git --help'. Did you mean one of these? am rm The cut-off is at similarity rating 6, which was empirically determined to give sensible results. As a convenience, if there is only one candidate, Git continues under the assumption that the user mistyped it.

| | | | | | | | | | | | This patch splits out git-help's functions to builtin-help.c and leaves only functions used by other builtins in help.c.

* Avoid chdir() in list_commands_in_dir()Johannes Schindelin2008-07-271-2/+10
| | | | | | | | | | | | | | The function list_commands_in_dir() tried to be lazy and just chdir() to the directory which entries it listed, so that the check if the file is executable could be done on dir->d_name. However, there is no good reason to jump around wildly just to find all Git commands. Instead, have a strbuf and construct the full path dynamically.

* | help (Windows): Display HTML in default browser using Windows' shell APISteffen Prohaska2008-07-131-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The system's default browser for displaying HTML help pages is now used directly on Windows, instead of launching git-web--browser, which requires a Unix shell. 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.

|/ | | | | | | | | | | | | | If htmldir (in the Makefile) is a relative path, this path will now be interpreted relative to git_exec_path. This can be used to create an installation that can be moved to a different directory without re-compiling. The Windows installer (msysgit) is an example for such a setup. Note that the Makefile maps htmldir to the define GIT_HTML_PATH.

| * Windows: Make 'git help -a' work.Johannes Sixt2008-06-261-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git help -a scans the PATH for git commands. 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. Therefore, this strategy is a special-case local to help.c. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
* | help: check early if we have a command, if not try a documentation topicChristian Couder2008-06-271-8/+14
|/ | | | | | | | | | | | | | | | | | Before this patch, something like "git help tutorial" did not work, people had to use "git help gittutorial" which is not very intuitive. This patch uses the "is_git_command" function to test early if the argument passed to "git help" is a git command, and if this is not the case then we prefix the argument with "git" instead of "git-". This way, things like "git help tutorial" or "git help glossary" will work fine. The little downside of this patch is that the "is_git_command" is a little bit slow.

* help: use "man.<tool>.cmd" as custom man viewer commandChristian Couder2008-04-261-18/+40
| | | | | | | | | | | | | | | | | | | | 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.

* help: use man viewer path from "man.<tool>.path" config varChristian Couder2008-04-261-19/+124
| | | | | | | | | | | | | | | | | | | This patch implements reading values from "man.<tool>.path" configuration variables, and using these values as pathes to the man viewer <tool>s when lauching them. This makes it possible to use different version of the tools than the one on the current PATH, or maybe a custom script. In this patch we also try to launch "konqueror" using "kfmclient" even if a path to a konqueror binary is given in "man.konqueror.path". The "man_viewer_list" becomes a simple string list to simplify things for the following patches.

It also implements support for emacs' "woman" and konqueror with the man KIO slave to view man pages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "git-help--browse" helper is to launch a browser of the user's choice to view the HTML version of git documentation for a given command. It used to take the name of a command, convert it to the path of the documentation by prefixing the directory name and appending the ".html" suffix, and start the browser on the path. This updates the division of labor between the caller in help.c and git-help--browser helper. The helper is now responsible for launching a browser of the user's choice on given URLs, and it is the caller's responsibility to tell it the paths to documentation files. This is in preparation to reuse the logic to choose user's preferred browser in instaweb. The helper had a provision for running it without any command name, in which case it showed the toplevel "git(7)" documentation, but the caller in help.c never makes such a call. The helper now exits with a usage message when no path is given. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
