.Sh DESCRIPTION
Connect to a scuttlebot/secret-stack server, and call a method on it, with
standard I/O.
.Sh OPTIONS
.Bl -tag
.It Fl j
Send stdin data as JSON.
.It Fl l
Don't output newlines after string or JSON packets.
.It Fl r
Raw mode. Disables stdin line buffering/editing and echoing. Implies
.Fl l .
.It Fl e
Encode arguments as strings, rather than expecting them to be JSON-encoded.
.It Fl T
Test using shs1-testsuite protocol. Instead of connecting to a server and running
a command, connect to stdio. On successful handshake, output concatenation of
the encryption key, encryption nonce, decryption key and decryption nonce.
.It Fl a
Passthrough mode. Instead of making a muxrpc call, pass through the box-stream
to stdio.
.It Fl n
Noauth mode. Skip secret-handshake authentication and box-stream encryption.
This option makes the
.Fl k ,
.Fl K ,
and
.Fl c
options have no effect and output a warning if used.
.It Fl 4
Connect to server over IPv4 only.
.It Fl 6
Connect to server over IPv6 only.
.It Fl c Ar cap
Capability key for secret-handshake. Default is SSB's capability key,
.Li 1KHLiKZvAvjbY1ziZEHMXawbCEIM6qwjCDm3VYRan/s= .
.It Fl s Ar host
The hostname to connect to. Default is localhost. If set to localhost and connection to localhost fails,
.Nm
may attempt to connect to other local interface addresses.
.It Fl p Ar port
The port to connect to. Default is 8008.
.It Fl u Ar socket_path
Unix socket path to connect to, instead of TCP socket. Conflicts with
.Fl p
and
.Fl s .
.It Fl k Ar key
The key to connect to. Default is your public key, as read from your
private key file.
.It Fl K Ar keypair
Private key or private key seed to use for secret-handshake. Default is to use the private key
from your
.Pa ~/.ssb/secret
file or other secret file according to the environmental variables described in
.Sx ENVIRONMENT .
.It Fl t Ar type
The type of method:
.Dq async ,
.Dq source ,
.Dq sink ,
or
.Dq duplex .
Default is to look up the method in
.Pa ~/.ssb/manifest.json .
.It Ar method
Method name.
.It Op Ar argument ...
Arguments to pass to the method call. Each argument must be JSON-encoded, unless the
.Fl e
option is used, in which the arguments are treated as strings.
.El
.Sh ENVIRONMENT
.Bl -tag
.It Ev ssb_appname
Name of the app. Default is
.Dq ssb .
Used to construct the app's directory if
.Ev ssb_path
is not present.
.It Ev ssb_path
Path to the app's directory. Default is to use
.Ev ssb_appname to construct the path as
.Dq ~/.<ssb_appname>
.El
.Sh FILES
.Bl -tag -width -indent
.It Pa ~/.ssb/secret
Your private key, used for authenticating to the server with the
secret-handshake protocol.
.It Pa ~/.ssb/manifest.json
A map of method names to method types.
.It Pa ~/.ssb/config
JSON file containing key, host, port, and/or SHS cap key to use if the
.Fl s ,
.Fl p
or
.Fl c
options are not given, respectively.
.It Pa ~/.ssb/socket
UNIX socket stream file for noauth connections.
If none of the options
.Fl s ,
.Fl p ,
.Fl u ,
.Fl c ,
.Fl k ,
.Fl K ,
.Fl c ,
.Fl 4 ,
.Fl 6 ,
or
.Fl T
are specified,
.Nm
will attempt to connect in noauth mode to this socket file. If the socket file
is not present or the connection fails,
.Nm
will fall back to connecting with TCP and secret-handshake according to the
config file - unless the
.Fl n
option is specified, in which case the command will fail.
.El
.Pp
The base path
.Dq ~/.ssb/
of these file names may be changed by setting
.Ev ssb_appname
or
.Ev ssb_path .
.Sh EXIT STATUS
.Bl -tag -width Ds
.It 0
The command completed successfully.
.It 1
An error occurred.
.It 2
The command completed with an error.
