Create a new "File formats, protocols and other developer interfaces"
section in the main "git help git" manual page and start moving the
documentation that now lives in "Documentation/technical/*.git" over
to it. This complements the newly added and adjacent "Repository,
command and file interfaces" section.
This makes the technical documentation more accessible and
discoverable. Before this we wouldn't install it by default, and had
no ability to build man page versions of them. The links to them from
our existing documentation link to the generated HTML version of these
docs.
So let's start moving those over, starting with just the
"bundle-format.txt" documentation added in 7378ec90e1 (doc: describe
Git bundle format, 2020-02-07). We'll now have a new
gitformat-bundle(5) man page. Subsequent commits will move more git
internal format documentation over.
Unfortunately the syntax of the current Documentation/technical/*.txt
is not the same (when it comes to section headings etc.) as our
Documentation/*.txt documentation, so change the relevant bits of
syntax as we're moving this over.

----
|
|
git-help - Display help information about Git
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git help' [-a|--all] [--[no-]verbose] [--[no-]external-commands] [--[no-]aliases]
|
|
'git help' [[-i|--info] [-m|--man] [-w|--web]] [<command>|<doc>]
|
|
'git help' [-g|--guides]
|
|
'git help' [-c|--config]
|

'git help' [--user-interfaces]
|
|
'git help' [--developer-interfaces]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
With no options and no '<command>' or '<doc>' 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 other documentation is given, the relevant manual page
|
|
will be 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.
|
|
|
|
--no-external-commands::
|
|
When used with `--all`, exclude the listing of external "git-*"
|
|
commands found in the `$PATH`.
|
|
|
|
--no-aliases::
|
|
When used with `--all`, exclude the listing of configured
|
|
aliases.
|
|
|
|
--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.
|
|
|
|
--user-interfaces::
|
|
Prints a list of the repository, command and file interfaces
|
|
documentation on the standard output.
|
|
+
|
|
In-repository file interfaces such as `.git/info/exclude` are
|
|
documented here (see linkgit:gitrepository-layout[5]), as well as
|
|
in-tree configuration such as `.mailmap` (see linkgit:gitmailmap[5]).
|
|
+
|
|
This section of the documentation also covers general or widespread
|
|
user-interface conventions (e.g. linkgit:gitcli[7]), and
|
|
pseudo-configuration such as the file-based `.git/hooks/*` interface
|
|
described in linkgit:githooks[5].
|
|
|
|
--developer-interfaces::
|
|
Print list of file formats, protocols and other developer
|
|
interfaces documentation on the standard output.
|
|
|
|
-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.
|
|
See linkgit:git-config[1] for more information about this.
