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

   8 SYNOPSIS
   9 --------
  10 git remote add <nick> "ext::<command>[ <arguments>...]"
  11
  12 DESCRIPTION
  13 -----------
  14 This remote helper uses the specified '<command>' to connect
  15 to a remote git server.
  16
  17 Data written to stdin of the specified '<command>' is assumed
  18 to be sent to a git:// server, git-upload-pack, git-receive-pack
  19 or git-upload-archive (depending on situation), and data read
  20 from stdout of <command> is assumed to be received from
  21 the same service.
  22
  23 Command and arguments are separated by an unescaped space.
  24
  25 The 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 +
  49 This is useful if remote side is git:// server accessed over
  50 some 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
  57 ENVIRONMENT VARIABLES:
  58 ----------------------
  59
  60 GIT_TRANSLOOP_DEBUG::
  61         If set, prints debugging information about various reads/writes.
  62
  63 ENVIRONMENT VARIABLES PASSED TO COMMAND:
  64 ----------------------------------------
  65
  66 GIT_EXT_SERVICE::
  67         Set to long name (git-upload-pack, etc...) of service helper needs
  68         to invoke.
  69
  70 GIT_EXT_SERVICE_NOPREFIX::
  71         Set to long name (upload-pack, etc...) of service helper needs
  72         to invoke.
  73
  74
  75 EXAMPLES:
  76 ---------
  77 This remote helper is transparently used by git when
  78 you use commands such as "git fetch <URL>", "git clone <URL>",
  79 , "git push <URL>" or "git remote add <nick> <URL>", where <URL>
  80 begins 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).
