This program will be able to:
- Validate and parse exalang (generate a a syntax tree)
- Execute (a subset) of exalang
- Simulate multiple exas with interaction (stretch goal)
exaparse will be a module that will be able to:
- Validate a line of code
- Generate a syntax tree for a valid set of instructions
- Evalute lines of code. This will be a reducer in redux terminology
There will be a state machine included in the exaparse module.
The state will be a redux store object.
The program syntax tree will be part of the state.
The state will have:
- Registers
- Program Tree
- Program Counter (PC) - Indicates which line is going to execute currently
- Blocked - whether this is for reading on M register or not
There will be a few key reducers.
- eval - this takes the state of the exa, and update it to match what the state should be after executing the line at the current program counter
The reducer to evaluate, eval, will take in the current state and action. If
