Branching of action output

[ZdenekM]

From the design document...

• Each output of a suitable type (bool, enum) could be branched into more outputs.
• For instance output of type bool could be (virtually) divided into two outputs: False, True.
• This serves as an “integrated if block” and simplifies conditioning in simple (and probably frequent) cases where there is no need to add additional “if” block.
• In Python, this is translated to if/elif block handling all possible values.
• For types as int or float some kind of compare block (equals, greater_than, etc.) has to be used.
• If “if” is not necessary, the output could be just ignored or stored to a variable.

Action “bool_action” has one output of a type “bool” that is branched (divided) into two (true, false):

What needs to be done:

• [x] Review what is already implemented in the ARServer.
• [x] Divide parameter types into countable and uncountable
• [x] Implement checking of a condition in check_logic_item (link).
• [x] Support for boolean.
• [ ] Support for enums.
• [x] Deal with blind branches.
• [x] Add support for branching to Build.
• [ ] Write integration tests.
