USAGE

It is assumed that a virtual test-calvin environment is set up to run calvin-base, as described in virtualenv.md

Activate a environment in a separate terminal window, hereafter called Terminal 2

source ~/.virtualenvs/test-calvin/bin/activate

and your prompt should change to indicate the activation by prepending (test-calvin) to whatever was there before. Use deactivate if you should want to leave the virtual environment.

Start calvin runtime within virtualenv at Terminal 1

source ~/.virtualenvs/test-calvin/bin/activate

and deploy script test3.calvin

$ csruntime --keep-alive --host localhost --port 5000 --controlport 5001 calvin/scripts/test3.calvin

It is also possible to do all this through the web interface, as described in the setup for calvin base.

Activate the same virtual environment in a new separate terminal window, hereafter called Terminal 2

source ~/.virtualenvs/test-calvin/bin/activate

and your prompt should change to indicate the activation by prepending (test-calvin) to whatever was there before. Use deactivate if you should want to leave the virtual environment.

start calvin-mini runtime in Terminal 2

$ python calvin_mini.py

CTRL+Z stops the current process, which can then be resumed as a background process using the command bg.

Execute setup & migrate program to move the sink (io.StandardOut) from the big calvin runtime to the calvin-mini runtime.

$ python runme.py sink

this should move the output from Terminal 1 to Terminal 2.

N.B.

The runme.py has hardcoded the port used, therefore you cannot run this script twice to have another stdout actor used in another script moved to a calvin-mini instance wihtout assigning this to another port.

It is possible to know what process uses what port with lsof, e.g:

sudo lsof -iTCP:5000 -n -P'

to check which process uses port 5000. See 'man lsof' for (way too much) information.

Terminating calvin mini

If calvin mini executes in the background with bg you can move it to the foreground with fgand end it with CTRL-C.
