NAME
git-remote-ext - Bridge smart transport to external command.
SYNOPSIS
git remote add <nick> "ext::<command>[ <arguments>...]"
DESCRIPTION
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 rest of the argument. Default is not to
send such a request.
This is useful if 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 rest of the
argument). Default is not to send vhost in such request (if sent).
ENVIRONMENT VARIABLES:
GIT_TRANSLOOP_DEBUG
If set, prints debugging information about various reads/writes.
ENVIRONMENT VARIABLES PASSED TO COMMAND:
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.
EXAMPLES:
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 user on remote side. This avoids needing to
edit .ssh/config.
"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"
Represents repository with path /somerepo accessible over git
protocol at 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).
