   6git-remote-ext - Bridge smart transport to external command.

   8SYNOPSIS
   9--------
  10git remote add <nick> "ext::<command>[ <arguments>...]"
  11
  12DESCRIPTION
  13-----------
  14This remote helper uses the specified '<command>' to connect
  15to a remote git server.
  16
  17Data written to stdin of the specified '<command>' is assumed
  18to be sent to a git:// server, git-upload-pack, git-receive-pack
  19or git-upload-archive (depending on situation), and data read
  20from stdout of <command> is assumed to be received from
  21the same service.
  22
  23Command and arguments are separated by an unescaped space.
  24
  25The following sequences have a special meaning:
  26
  27'% '::
  28        Literal space in command or argument.
  29
  30'%%'::
  31        Literal percent sign.
  32
  33'%s'::
  34        Replaced with name (receive-pack, upload-pack, or
  35        upload-archive) of the service git wants to invoke.
  36
  37'%S'::
  38        Replaced with long name (git-receive-pack,
  39        git-upload-pack, or git-upload-archive) of the service
  40        git wants to invoke.
  41
  42'%G' (must be the first characters in an argument)::
  43        This argument will not be passed to '<command>'. Instead, it
  44        will cause the helper to start by sending git:// service requests to
  45        the remote side with the service field set to an appropriate value and
  46        the repository field set to rest of the argument. Default is not to send
  47        such a request.
  48+
  49This is useful if remote side is git:// server accessed over
  50some tunnel.
  51
  52'%V' (must be first characters in argument)::
  53        This argument will not be passed to '<command>'. Instead it sets
  54        the vhost field in the git:// service request (to rest of the argument).
  55        Default is not to send vhost in such request (if sent).
  56
  57ENVIRONMENT VARIABLES:
  58----------------------
  59
  60GIT_TRANSLOOP_DEBUG::
  61        If set, prints debugging information about various reads/writes.
  62
  63ENVIRONMENT VARIABLES PASSED TO COMMAND:
  64----------------------------------------
  65
  66GIT_EXT_SERVICE::
  67        Set to long name (git-upload-pack, etc...) of service helper needs
  68        to invoke.
  69
  70GIT_EXT_SERVICE_NOPREFIX::
  71        Set to long name (upload-pack, etc...) of service helper needs
  72        to invoke.
  73
  74
  75EXAMPLES:
  76---------
  77This remote helper is transparently used by git when
  78you use commands such as "git fetch <URL>", "git clone <URL>",
  79, "git push <URL>" or "git remote add <nick> <URL>", where <URL>
  80begins with `ext::`.  Examples:
  81
  82"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
  83        Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
  84        keypair and user as user on remote side. This avoids needing to
  85        edit .ssh/config.
  86
  87"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
  88        Represents repository with path /somerepo accessable over
  89        git protocol at abstract namespace address /git-server.
  90
  91"ext::git-server-alias foo %G/repo"::
  92        Represents a repository with path /repo accessed using the
  93        helper program "git-server-alias foo".  The path to the
  94        repository and type of request are not passed on the command
  95        line but as part of the protocol stream, as usual with git://
  96        protocol.
  97
  98"ext::git-server-alias foo %G/repo %Vfoo"::
  99        Represents a repository with path /repo accessed using the
 100        helper program "git-server-alias foo".  The hostname for the
 101        remote server passed in the protocol stream will be "foo"
 102        (this allows multiple virtual git servers to share a
 103        link-level address).
 104
 105"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
 106        Represents a repository with path '/repo with spaces' accessed
 107        using the helper program "git-server-alias foo".  The hostname for
 108        the remote server passed in the protocol stream will be "foo"
 109        (this allows multiple virtual git servers to share a
 110        link-level address).
 111
 112"ext::git-ssl foo.example /bar"::
 113        Represents a repository accessed using the helper program
 114        "git-ssl foo.example /bar".  The type of request can be
 115        determined by the helper using environment variables (see
 116        above).
