* help: check early if we have a command, if not try a documentation topicChristian Couder2008-06-27
| | | | | | | | | | | | | | | | | | 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.

* Print info about "git help COMMAND" on git's main usage pagesTeemu Likonen2008-06-06
| | | | | | | | | | Git's main usage pages did not show "git help" as a way to get more information on a specific subcommand. This patch adds an info line after the list of git commands currently printed by "git", "git help", "git --help" and "git help --all".

* Provide git_config with a callback-data parameterJohannes Schindelin2008-05-14
| | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

* help: use "man.<tool>.cmd" as custom man viewer commandChristian Couder2008-04-26
| | | | | | | | | | | | | | | | | | | | 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 Couder2008-04-26
| | | | | | | | | | | | | | | | | | | 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.

* help: warn if specified 'man.viewer' is unsupported, instead of erroring outChristian Couder2008-03-12
| | | | | | | | | | | | When a document viewer that is unknown to the current version of git is specified in the .git/config file, instead of erroring out the process entirely, just issue a warning. It might be that the user usually is using a newer git that supports it (and the configuration is written for that version) but is temporarily using an older git that does not know the viewer.

| | | | | | | | | | | | | 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 King2008-02-24
| | | | | | | | | | | | | | 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").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "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>

* git-help: add "help.format" config variable.Christian Couder2007-12-14
| | | | | | | | | | | | | | | | | | | | | | | | This config variable makes it possible to choose the default format used to display help. This format will be used only if no option like -a|--all|-i|--info|-m|--man|-w|--web is passed to "git-help". The following values are possible for this variable: - "man" --> "man" program is used - "info" --> "info" program is used - "web" --> "git-browse-help" is used By default we still show help using "man". This patch also adds -m|--man command line option to use "man" to allow overriding the "help.format" configuration variable. Note that this patch also revert some recent changes in "git-browse-help" because they prevented to look for config variables in the global configuration file.

* | git-help: add -w|--web option to display html man page in a browser.Christian Couder2007-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now when using "git help -w cmd", we will try to show the HTML man page "git-cmd.html" in your prefered web browser. To do that "help.c" code will call a new shell script "git-browse-help". This currently works only if the HTML versions of the man page have been installed in $(htmldir) (typically "/usr/share/doc/git-doc"), so new target to do that is added to "Documentation/Makefile". The browser to use can be configured using the "web.browser" config variable. We try to open a new tab in an existing web browser, if possible. The code in "git-browse-help" is heavily stolen from "git-mergetool" by Theodore Y. Ts'o. Thanks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>
