Bamboolean interpreter
Supported from Python >= 3.6
Implementation of Bamboolean - Boolean Logic Language
Bamboolean is a simple language that consumes array of pre-defined variables, and returns boolean value if constraints on these variables are met.
Exemplary expressions in the language
Features
- Case in-sensitive variable names and keywords
- Comparison operators (listed below)
- Logic AND / OR
- Expressions with parentheses
- Types: Float, Int, String, Bool, Variable
- Truth value testing same as in Python
- Implicit cast of variables to boolean when no relational operator is specified
Operators associativity
All operators are left-associative
Operators precedence (the higher number the higher priority)
- OR
- AND
- == | != | < | <= | > | >=
Testing
Run tests:
`python run_tests.py`
