Scripting use cases

• Some instruments never want more than one scripts running simultaneously

  • This is the "default" case for more than one instrument

• Some instruments want to run multiple control scrips in parallel:

  • LARMOR for example run a script that flips polarisation alongside a user script. Similar workflow on Vesuvio.

• There is a use case for one "control" script and one "visualisation" script simultaneously

  • the visualisation script can be purely read-only

• Muons make no distinction between script, script server, script generator.

  • Play about with some ideas in scripting
  • Then go to script generator to make full experimental script
  • Like the idea of editing a script which is sat in a queue

• Improve script server training materials.

  • But also has to be explainable to a (scientific) user in a short amount of time.
  • Has to be possible to run single lines (e.g. function calls with parameters)

Ideas

• Only enable write from within script server?

  • We would have to provide an override for some specific use cases

• Disable writing while acquisition is running (e.g. oak ridge). This could run into issues at ISIS.

• Enable load/execute in script server from within normal console window?

  • have a genie_python command g.queue_on_server()?
  • Future of g.load_script()

• As a user: go to script server, load script, execute it?

  • I might want to edit my script.

• load_script still loads script locally, but when I execute this function it should run on the script server?

• Nicos has a comamand for list_commands. We've currently only made it aware of g_p commands

• Use standard python? e.g. def main(): ... main()

Solution?

• g.run_file : loads and runs locally (right now)
• g.queue_file : loads and runs in the script server (queues)
• g.dry_run (queues in simulation mode - might be further in the future)
• Need a (small) scripting console in the nicos perspective
• Might need to disable queuing a script from within a script in the queue. Separate client/server g_p.
