It provides a user-friendly command interface that hides the details +of the message construction and delivery for common tasks. By default, +a message will be broadcast to all other SAMP-enabled applications, the +<I>-t</I> (or <I>--to</I>) flag can be used to name a specific receipient by +either the public ID or the application name, the <I>-p</I> flag will accept +a 'sync' or 'notify' argument to change the default message pattern of +asynchronous delivery. +<P> + +In order to minimize the overhead of connecting with the Hub on each command, +<I>vosamp</I> will spawn a proxy process that remains connected to the Hub and +will process subsequent commands transparently. This proxy process will +timeout after some period of inactivity and may be accessed from remote +machines (see below for more information). +<P> +<P> +<A NAME="lbAF"> </A> +<H2>COMMAND SUMMARY</H2> + +<P> + +The <I>vosamp</I> task accepts the following commands, specified either on +the command-line argument list or in interactive mode: +<P> + +<B>snoop<TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT></B> + + +Print all received messages.<BR> +<P> + +<B>send <mtype> [<args>...]<TT> </TT><TT> </TT><TT> </TT></B> + + +Generalized message send. The <mtype> parameter can be either one of <BR> +the well-known SAMP mtypes or an ad hoc mtype that can be expected to be +recognized by other apps. The <I><args></I> parameter refers +to any of the arguments necessary for the specifed mtype. The <I><args></I> +may be specified as a sequence of values and will be delivered using +parameter names of the form "argN", to send named parameters the argument +must be specified as "<name>:<value>". +<P> + +<B>status<TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT></B> + + +Print Hub availability.<BR> +<P> + +<B>list<TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT><TT> </TT></B> + + +List all registered clients.<BR> +<P> + +<B>access <appName><TT> </TT><TT> </TT><TT> </TT><TT> </TT></B> + + +Print <appName> availability.

This command will subscribe the task<BR> +to the specified <mtype> and when it is received will print the contents of +the message to the stdout stream.

This +registration can add significant overhead to an application that may only +send a single message, significantly slowing it's use within a scripting +environment. Unless the <I>-n</I> (or <I>--nokeepalive</I>) flag is set, +the first time VOSAMP is started it will execute the specified command +and then fork a child process that stays connected to the Hub. Subsequent +VOSAMP calls will simply forward the command to this child proxy process, +thereby avoiding a new Hub registration. +<P> + +The proxy process by default will listen on inet port 3999 (as of this writing +there is no option to change it) for new commands, however there is no +restriction that the only application that can connect to it must be running +on the same host. The <I>-P</I> (or <I>--proxy</I>) flag can be used to +specify an alternate proxy to be used; the argument is of the form + +<I>node</I> [ ':' <I>port</I> ] +<P> + +where <I>node</I> can be a simple host name, a fully-qualified domain name or +and IP address, and <I>port</I> number number is optional. The proxy will +run for up to an hour if no new commands are received before disconnecting +from the Hub, this timeout value may be changed by using the <I>-T</I> flag +to specify the timeout in seconds. +<P> +<A NAME="lbAH"> </A> +<H2>RETURN STATUS</H2> + +On exit the <B>vosamp</B> task will return a zero indicating success, or a +one indicating an error. +<P> +<A NAME="lbAI"> </A> +<H2>EXAMPLES</H2> + +<DL COMPACT> +<DT>1) Load a VOTable to Topcat:<DD> +<P> +<PRE> + % vosamp load /path/example.xml + % vosamp load <A HREF="http://foo.edu/example.xml">http://foo.edu/example.xml</A> + % vosamp load <A HREF="http://foo.edu/query?RA=0.0">http://foo.edu/query?RA=0.0</A>&DEC=0.0&SR=0.1 +</PRE> + +<DT>2) Send a command string to IRAF:<DD> +<P> +<PRE> + % vosamp -t iraf exec "display dev$pix 1" +</PRE> + +<DT>3) List all clients in a SAMP desktop session:<DD> +<P> +<PRE> + % vosamp list +</PRE> + +<DT>4) Check whether a Hub is available from a script:<DD> +<P> +<PRE> + set isHub = `vosamp access Hub` + if ($isHub == "no") then + echo "No Hub available, quitting ....." + exit $status + endif +</PRE> + +<P> +<P> +<P> +</DL> +<A NAME="lbAJ"> </A> +<H2>BUGS</H2> + +No known bugs with this release. +<A NAME="lbAK"> </A> +<H2>KNOWN SHORTCOMINGS</H2> + +No known bugs with this release. + +- The 'handle' command should allow a command to be executed with message argument substitution. + +- A flag is needed to change the child proxy port being used +<P> +<A NAME="lbAL"> </A> +<H2>Revision History</H2> + +Feb 2013 - First public release +<A NAME="lbAM"> </A> +<H2>Author</H2> + +Michael Fitzpatrick (<A HREF="mailto:fitz@noao.edu">fitz@noao.edu</A>), Feb 2013 +<A NAME="lbAN"> </A> +<H2>SEE ALSO</H2> + +<P> +<P> + +The description of commonly used SAMP mtypes is gen at +<P> + +<A HREF="http://wiki.ivoa.net/twiki/bin/view/IVOA/SampMTypes">http://wiki.ivoa.net/twiki/bin/view/IVOA/SampMTypes</A> +<P> +<P> + +<HR> +<A NAME="index"> </A><H2>Index</H2> +<DL> +<DT><A HREF="#lbAB">NAME</A><DD> +<DT><A HREF="#lbAC">SYNOPSIS</A><DD> +<DT><A HREF="#lbAD">OPTIONS</A><DD> +<DT><A HREF="#lbAE">DESCRIPTION</A><DD> +<DT><A HREF="#lbAF">COMMAND SUMMARY</A><DD> +<DT><A HREF="#lbAG">KEEP-ALIVE CONNECTIONS</A><DD> +<DT><A HREF="#lbAH">RETURN STATUS</A><DD> +<DT><A HREF="#lbAI">EXAMPLES</A><DD> +<DT><A HREF="#lbAJ">BUGS</A><DD> +<DT><A HREF="#lbAK">KNOWN SHORTCOMINGS</A><DD> +<DT><A HREF="#lbAL">Revision History</A><DD> +<DT><A HREF="#lbAM">Author</A><DD> +<DT><A HREF="#lbAN">SEE ALSO</A><DD> +</DL> +<HR> +This document was created by +<A HREF="http://localhost/cgi-bin/man/man2html">man2html</A>, +using the manual pages.<BR> +Time: 06:21:57 GMT, April 26, 2013 +</BODY> +</HTML> |
