unfortunately, there isn't a really easy way of doing this, but after
pondering the problem for a while, I came up with the following solution
which I hope will work in your case.
Firstly, enable groovy scripting in jalview by downloading the groovy
binary distribution from groovy.codehouse.org. You then need to copy the
'groovy-all-1.X.jar' file from the 'embedded' directory into your
jalview's lib directory.
If this worked, then when you restart Jalview, you should see a new menu
entry under the Tools menu: 'Groovy Console ...'. Select that option to
open a groovy script execution window.
Now cut'n'paste the line(s) below into the script input area (top half
of the groovy console) :
new GroovyShell(), false, "(new
Pressing 'Ctrl-R' will execute the script, and you should see something
like 'groovy is listening on port 1962' appear in the output half of the
console window. You now have a server set up that will try to use any
text sent on port 1962 as a filename to open with the running Jalview.
To test it out, try :
echo <alignment filename> | nc localhost 1962
If there are any problems, then you'll see errors written on Jalview's
java console (opened using the Tools->Java Console' menu entry. If you
use this regularly, I suggest you save the groovy script to a file, and
pass it to Jalview on startup with the -groovy <scriptfile> argument.
ps. you can put in any bit of groovy scripting in the third argument to
the GroovySocketServer constructor. For instance, you might want to tag
on any additional commands, such as loading default features, etc. For
full details, start with the javadoc for the groovy socket server here:
