git-remote-ext(1)

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).
