Since 1b81d8cb19 (help: use command-list.txt for the source of guides,
2018-05-20), all man5/man7 guides listed in command-list.txt appear in
the output of 'git help -g'.
However, 'git help -g' still prefixes this list with "The common Git
guides are:", which makes one wonder if there are others!
In the same spirit, the man page for 'git help' describes the '--guides'
option as listing 'useful' guides, which is not false per se but can
also be taken to mean that there are other guides that exist but are not
useful.
Instead of 'common' and 'useful', use 'Git concept guides' in both
places. To keep the code in line with this change, rename
help.c::list_common_guides_help to list_guides_help.

NAME
|
|
----
|
|
git-help - Display help information about Git
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git help' [-a|--all [--[no-]verbose]] [-g|--guides]
|
|
[-i|--info|-m|--man|-w|--web] [COMMAND|GUIDE]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
With no options and no COMMAND or GUIDE given, the synopsis of the 'git'
|
|
command and a list of the most commonly used Git commands are printed
|
|
on the standard output.
|
|
|
|
If the option `--all` or `-a` is given, all available commands are
|
|
printed on the standard output.
|
|
|
|
If the option `--guides` or `-g` is given, a list of the
|
|
Git concept guides is also printed on the standard output.
|
|
|
|
If a command, or a guide, is given, a manual page for that command or
|
|
guide is brought up. The 'man' program is used by default for this
|
|
purpose, but this can be overridden by other options or configuration
|
|
variables.
|
|
|
|
If an alias is given, git shows the definition of the alias on
|
|
standard output. To get the manual page for the aliased command, use
|
|
`git COMMAND --help`.
|
|
|
|
Note that `git --help ...` is identical to `git help ...` because the
|
|
former is internally converted into the latter.
|
|
|
|
To display the linkgit:git[1] man page, use `git help git`.
|
|
|
|
This page can be displayed with 'git help help' or `git help --help`
|
|
|
|
OPTIONS
|
|
-------
|
|
-a::
|
|
--all::
|
|
Prints all the available commands on the standard output. This
|
|
option overrides any given command or guide name.
|
|
|
|
--verbose::
|
|
When used with `--all` print description for all recognized
|
|
commands. This is the default.
|
|
|
|
-c::
|
|
--config::
|
|
List all available configuration variables. This is a short
|
|
summary of the list in linkgit:git-config[1].
|
|
|
|
-g::
|
|
--guides::
|
|
Prints a list of the Git concept guides on the standard output. This
|
|
option overrides any given command or guide name.
|
|
|
|
-i::
|
|
--info::
|
|
Display manual page for the command in the 'info' format. The
|
|
'info' program will be used for that purpose.
|
|
|
|
-m::
|
|
--man::
|
|
Display manual page for the command in the 'man' format. This
|
|
option may be used to override a value set in the
|
|
`help.format` configuration variable.
|
|
+
|
|
By default the 'man' program will be used to display the manual page,
|
|
but the `man.viewer` configuration variable may be used to choose
|
|
other display programs (see below).
|
|
|
|
-w::
|
|
--web::
|
|
Display manual page for the command in the 'web' (HTML)
|
|
format. A web browser will be used for that purpose.
|
|
+
|
|
The web browser can be specified using the configuration variable
|
|
`help.browser`, or `web.browser` if the former is not set. If none of
|
|
these config variables is set, the 'git web{litdd}browse' helper script
|
|
(called by 'git help') will pick a suitable default. See
|
|
linkgit:git-web{litdd}browse[1] for more information about this.
|
|
|
|
CONFIGURATION VARIABLES
|
|
-----------------------
|
|
|
|
help.format
|
|
~~~~~~~~~~~
|
|
|
|
If no command-line option is passed, the `help.format` configuration
|
|
variable will be checked. The following values are supported for this
|
|
variable; they make 'git help' behave as their corresponding command-
|
|
line option:
|
|
|
|
* "man" corresponds to '-m|--man',
|
|
* "info" corresponds to '-i|--info',
|
|
* "web" or "html" correspond to '-w|--web'.
|
|
|
|
help.browser, web.browser and browser.<tool>.path
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The `help.browser`, `web.browser` and `browser.<tool>.path` will also
|
|
be checked if the 'web' format is chosen (either by command-line
|
|
option or configuration variable). See '-w|--web' in the OPTIONS
|
|
section above and linkgit:git-web{litdd}browse[1].
|
|
|
|
man.viewer
|
|
~~~~~~~~~~
|
|
|
|
The `man.viewer` configuration variable will be checked if the 'man'
|
|
format is chosen. The following values are currently supported:
|
|
|
|
* "man": use the 'man' program as usual,
|
|
* "woman": use 'emacsclient' to launch the "woman" mode in emacs
|
|
(this only works starting with emacsclient versions 22),
|
|
* "konqueror": use 'kfmclient' to open the man page in a new konqueror
|
|
tab (see 'Note about konqueror' below).
|
|
|
|
Values for other tools can be used if there is a corresponding
|
|
`man.<tool>.cmd` configuration entry (see below).
|
|
|
|
Multiple values may be given to the `man.viewer` configuration
|
|
variable. Their corresponding programs will be tried in the order
|
|
listed in the configuration file.
|
|
|
|
For example, this configuration:
|
|
|
|
------------------------------------------------
|
|
[man]
|
|
viewer = konqueror
|
|
viewer = woman
|
|
------------------------------------------------
|
|
|
|
will try to use konqueror first. But this may fail (for example, if
|
|
DISPLAY is not set) and in that case emacs' woman mode will be tried.
|
|
|
|
If everything fails, or if no viewer is configured, the viewer specified
|
|
in the `GIT_MAN_VIEWER` environment variable will be tried. If that
|
|
fails too, the 'man' program will be tried anyway.
|
|
|
|
man.<tool>.path
|
|
~~~~~~~~~~~~~~~
|
|
|
|
You can explicitly provide a full path to your preferred man viewer by
|
|
setting the configuration variable `man.<tool>.path`. For example, you
|
|
can configure the absolute path to konqueror by setting
|
|
'man.konqueror.path'. Otherwise, 'git help' assumes the tool is
|
|
available in PATH.
|
|
|
|
man.<tool>.cmd
|
|
~~~~~~~~~~~~~~
|
|
|
|
When the man viewer, specified by the `man.viewer` configuration
|
|
variables, is not among the supported ones, then the corresponding
|
|
`man.<tool>.cmd` configuration variable will be looked up. If this
|
|
variable exists then the specified tool will be treated as a custom
|
|
command and a shell eval will be used to run the command with the man
|
|
page passed as arguments.
|
|
|
|
Note about konqueror
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
When 'konqueror' is specified in the `man.viewer` configuration
|
|
variable, we launch 'kfmclient' to try to open the man page on an
|
|
already opened konqueror in a new tab if possible.
|
|
|
|
For consistency, we also try such a trick if 'man.konqueror.path' is
|
|
set to something like `A_PATH_TO/konqueror`. That means we will try to
|
|
launch `A_PATH_TO/kfmclient` instead.
|
|
|
|
If you really want to use 'konqueror', then you can use something like
|
|
the following:
|
|
|
|
------------------------------------------------
|
|
[man]
|
|
viewer = konq
|
|
|
|
[man "konq"]
|
|
cmd = A_PATH_TO/konqueror
|
|
------------------------------------------------
|
|
|
|
Note about git config --global
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Note that all these configuration variables should probably be set
|
|
using the `--global` flag, for example like this:
|
|
|
|
------------------------------------------------
|
|
$ git config --global help.format web
|
|
$ git config --global web.browser firefox
|
|
------------------------------------------------
|
|
|
|
as they are probably more user specific than repository specific.
|
|
