   8 SYNOPSIS
   9 --------
  10 [verse]
  11 git remote add <nick> "ext::<command>[ <arguments>...]"
  12
  13 DESCRIPTION
  14 -----------
  15 This remote helper uses the specified '<command>' to connect
  16 to a remote Git server.
  17
  18 Data written to stdin of the specified '<command>' is assumed
  19 to be sent to a git:// server, git-upload-pack, git-receive-pack
  20 or git-upload-archive (depending on situation), and data read
  21 from stdout of <command> is assumed to be received from
  22 the same service.
  23
  24 Command and arguments are separated by an unescaped space.
  25
  26 The following sequences have a special meaning:
  27
  28 '% '::
  29         Literal space in command or argument.
  30
  31 '%%'::
  32         Literal percent sign.
  33
  34 '%s'::
  35         Replaced with name (receive-pack, upload-pack, or
  36         upload-archive) of the service Git wants to invoke.
  37
  38 '%S'::
  39         Replaced with long name (git-receive-pack,
  40         git-upload-pack, or git-upload-archive) of the service
  41         Git wants to invoke.
  42
  43 '%G' (must be the first characters in an argument)::
  44         This argument will not be passed to '<command>'. Instead, it
  45         will cause the helper to start by sending git:// service requests to
  46         the remote side with the service field set to an appropriate value and
  47         the repository field set to rest of the argument. Default is not to send
  48         such a request.
  49 +
  50 This is useful if remote side is git:// server accessed over
  51 some tunnel.
  52
  53 '%V' (must be first characters in argument)::
  54         This argument will not be passed to '<command>'. Instead it sets
  55         the vhost field in the git:// service request (to rest of the argument).
  56         Default is not to send vhost in such request (if sent).
  57
  58 ENVIRONMENT VARIABLES
  59 ---------------------
  60
  61 GIT_TRANSLOOP_DEBUG::
  62         If set, prints debugging information about various reads/writes.
  63
  64 ENVIRONMENT VARIABLES PASSED TO COMMAND
  65 ---------------------------------------
  66
  67 GIT_EXT_SERVICE::
  68         Set to long name (git-upload-pack, etc...) of service helper needs
  69         to invoke.
  70
  71 GIT_EXT_SERVICE_NOPREFIX::
  72         Set to long name (upload-pack, etc...) of service helper needs
  73         to invoke.

  76 EXAMPLES
  77 --------
  78 This remote helper is transparently used by Git when
  79 you use commands such as "git fetch <URL>", "git clone <URL>",
  80 , "git push <URL>" or "git remote add <nick> <URL>", where <URL>
  81 begins with `ext::`.  Examples:
  82
  83 "ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
  84         Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
  85         keypair and user as user on remote side. This avoids needing to
  86         edit .ssh/config.
  87
  88 "ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
  89         Represents repository with path /somerepo accessible over
  90         git protocol at abstract namespace address /git-server.
  91
  92 "ext::git-server-alias foo %G/repo"::
  93         Represents a repository with path /repo accessed using the
  94         helper program "git-server-alias foo".  The path to the
  95         repository and type of request are not passed on the command
  96         line but as part of the protocol stream, as usual with git://
  97         protocol.
  98
  99 "ext::git-server-alias foo %G/repo %Vfoo"::
 100         Represents a repository with path /repo accessed using the
 101         helper program "git-server-alias foo".  The hostname for the
 102         remote server passed in the protocol stream will be "foo"
 103         (this allows multiple virtual Git servers to share a
 104         link-level address).
 105
 106 "ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
 107         Represents a repository with path `/repo with spaces` accessed
 108         using the helper program "git-server-alias foo".  The hostname for
 109         the remote server passed in the protocol stream will be "foo"
 110         (this allows multiple virtual Git servers to share a
 111         link-level address).
 112
 113 "ext::git-ssl foo.example /bar"::
 114         Represents a repository accessed using the helper program
 115         "git-ssl foo.example /bar".  The type of request can be
 116         determined by the helper using environment variables (see
 117         above).
