OpenWhisk runtimes for prolog

This OpenWhisk runtimes provide SWI Prolog 7.5 environment for Prolog predicate, Prolog script, and Prolog compiled binary.

Build

ubuntu@trusty:~/openwhisk-runtime-prolog[master]$ make build -e docker_image_prefix=myprefix

ubuntu@trusty:~/openwhisk-runtime-prolog[master]$ make push -e docker_image_prefix=myprefix

Usage

Text Mode

• execute "main" predicate of hello_world.pl

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action create hello_prolog hello_world.pl --docker ${docker_image_prefix}/swipl7action -i
ok: created action hello_prolog

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action invoke hello_prolog -p name Prolog -ir
{
    "payload": "Hello, Prolog!"
}

• execute "start" predicate of hello_world_start.pl

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action create hello_start hello_world_start.pl --main start --docker ${docker_image_prefix}/swipl7action -i
ok: created action hello_start

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action invoke hello_start -p name Entrypoint -ir
{
    "payload": "Hello, Entrypoint!"
}

Binary Mode

• execute Prolog script, hello_script, which file name can be specified as '--main' parameter.

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ ./hello_world_script '{"name":"Script"}'
{"payload":"Hello, Script!"}

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ zip hello_world_script.zip hello_world_script
  adding: hello_world_script (deflated 43%)

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action create hello_script hello_world_script.zip --main hello_world_script --docker ${docker_image_prefix}/swipl7action -i
ok: created action hello_script

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ wsk action invoke hello_script -p name PrologScript -ir
{
    "payload": "Hello, PrologScript!"
}

• execute Prolog compiled binary, myexec, which file name can be specified as '--main' parameter.

ubuntu@trusty:~/openwhisk-runtime-prolog/samples/actions[master]$ swipl -O --goal=go --stand_alone=true -o myexec -c hello_world_bin.pl
