GIT-REMOTE-EXT(1) Git Manual GIT-REMOTE-EXT(1)
git-remote-ext - Bridge smart transport to external command.
git remote add <nick> "ext::<command>[ <arguments>...]"
This remote helper uses the specified <command> to connect to a
remote Git server.
Data written to stdin of the specified <command> is assumed to be
sent to a git:// server, git-upload-pack, git-receive-pack or
git-upload-archive (depending on situation), and data read from
stdout of <command> is assumed to be received from the same
service.
Command and arguments are separated by an unescaped space.
The following sequences have a special meaning:
'% '
Literal space in command or argument.
%%
Literal percent sign.
%s
Replaced with name (receive-pack, upload-pack, or
upload-archive) of the service Git wants to invoke.
%S
Replaced with long name (git-receive-pack, git-upload-pack, or
git-upload-archive) of the service Git wants to invoke.
%G (must be the first characters in an argument)
This argument will not be passed to <command>. Instead, it
will cause the helper to start by sending git:// service
requests to the remote side with the service field set to an
appropriate value and the repository field set to the rest of
the argument. Default is not to send such a request.
This is useful if the remote side is git:// server accessed
over some tunnel.
%V (must be first characters in argument)
This argument will not be passed to <command>. Instead it sets
the vhost field in the git:// service request (to the rest of
the argument). Default is not to send vhost in such request
(if sent).
GIT_TRANSLOOP_DEBUG
If set, prints debugging information about various
reads/writes.
GIT_EXT_SERVICE
Set to long name (git-upload-pack, etc...) of service helper
needs to invoke.
GIT_EXT_SERVICE_NOPREFIX
Set to long name (upload-pack, etc...) of service helper needs
to invoke.
This remote helper is transparently used by Git when you use
commands such as "git fetch <URL>", "git clone <URL>", , "git push
<URL>" or "git remote add <nick> <URL>", where <URL> begins with
ext::. Examples:
"ext::ssh -i /home/foo/.ssh/somekey user@host.example %S foo/repo"
Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
keypair and user as the user on the remote side. This avoids
the need to edit .ssh/config.
"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"
Represents repository with path /somerepo accessible over git
protocol at the abstract namespace address /git-server.
"ext::git-server-alias foo %G/repo"
Represents a repository with path /repo accessed using the
helper program "git-server-alias foo". The path to the
repository and type of request are not passed on the command
line but as part of the protocol stream, as usual with git://
protocol.
"ext::git-server-alias foo %G/repo %Vfoo"
Represents a repository with path /repo accessed using the
helper program "git-server-alias foo". The hostname for the
remote server passed in the protocol stream will be "foo"
(this allows multiple virtual Git servers to share a
link-level address).
"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"
Represents a repository with path /repo with spaces accessed
using the helper program "git-server-alias foo". The hostname
for the remote server passed in the protocol stream will be
"foo" (this allows multiple virtual Git servers to share a
link-level address).
"ext::git-ssl foo.example /bar"
Represents a repository accessed using the helper program
"git-ssl foo.example /bar". The type of request can be
determined by the helper using environment variables (see
above).
