FLDIGI-SHELL(1)
===============


== NAME ==
fldigi-shell - program for controlling fldigi


== SYNOPSIS ==
*fldigi-shell* ['OPTIONS'] ['FILE']


== DESCRIPTION ==
The fldigi-shell program controls +fldigi(1)+ over HTTP via XML-encoded remote
procedure calls (XML-RPC). It can call any XML-RPC method exported by fldigi,
and also defines some useful commands of its own.


== OPTIONS ==
*-d*::
  Enable debug output.

*-u* 'URL'::
  Use 'URL' to access the server. Defaults to ``http://localhost:7362/RPC2'',
  which corresponds to fldigi's default listen address and port.

*-c* 'COMMAND'::
  Execute command 'COMMAND' and exit.


== COMMANDS ==
[NOTE]
================================================================================
The ``x:yz'' notation refers to the return type and argument type(s). They are:
``n'' (nil), ``i'' (integer), and ``s'' (string).
================================================================================

debug (n:n:)::
  Toggle debug output.

eval (s:s)::
  Evaluate Perl code.

exit (n:n)::
  Exit the shell.

help (n:n)::
  Print help for server (fldigi) methods and shell commands.

history (s:n)::
  Print command history.

modems (s:n)::
  List all modem names.

poll (s:i)::
  Poll for new received text every 'i' seconds. Defaults to '1'.

pskrqsy (n:si)::
  QSY to 'i'^th^ best frequency for grid 's'. The list of frequencies is
  retrieved from the PSK Reporter website; see *RESOURCES*.  The grid square
  string may be left empty, and the index argument defaults to '0' (first
  frequency).

recvtext (s:n)::
  Get all received text.

reinit (n:n)::
  Fetch commands from the server and rebuild command list.

send (n:s)::
  Send text interactively, one line at a time.

sendchar (n:s)::
  Send text interactively, one character at a time.

sendfile (n:s)::
  Send text read from file 's'.

sendstr (n:s)::
  Send string 's'.

source (n:s)::
  Read commands from file 's'.

time (s:s)::
  Time a command.

wait (n:s)::
  Wait for server TRX state to become 's'.


== EXTENDED DESCRIPTION ==
The shell has three modes of operation:

. Interactive mode with history, tab completion and command line editing. This
  is the default mode when fldigi-shell is run without arguments.

. Batch mode for a single command with the *-c* option.

. Batch mode to ``source'' a file containing Perl code.  Fldigi-shell commands
  can be called using ``execute("COMMAND [ARG ...]")'' calls.


== FILES ==
$HOME/.fldigi/shell-history::
  Contains the fldigi-shell command history.


== EXAMPLES ==
+while :; do fldigi-shell -c pskrqsy; sleep 900; done+::
  Change to the ``best frequency'' (see PSK Reporter) every fifteen minutes.


== SEE ALSO ==
fldigi(1), xmlrpc(1), readline(3), RPC::XML(3pm)


== BUGS ==
* Some additional command wrappers are needed.
* Command completion should be enabled for the arguments of some commands.
* The XML-RPC handling code should probably go in a separate module.
* It should be possible to pass multiple '-c CMD' arguments.
