Python compiler for the Neo3 Virtual Machine

Overview

Overview

The neo3-boa compiler is a tool for compiling Python files to the .nef and .manisfest.json formats for usage in the Neo Virtual Machine which is used to execute contracts on the Neo Blockchain.

What it currently does…

Compiles a subset of the Python language to the .nef and .manisfest.json format for use in the Neo Virtual Machine
Works for Python 3.7+
Logs compiler errors and warnings
Logs when the main method is analysed
Logs method inclusions in .abi file to work with Neo Debuggers.
Converts Functions
Converts Local Variable Declarations and Assignments

foo: int = 42
bar = foo

Converts Number Arithmetic Operations (+, -, *, //, %)
Converts Numeric Arithmetic Augmented assignment Operators (+=, -=, *=, //=, %=)
Converts Relational Operations (==, !=, <, <=, >, >=)
Converts Boolean Logic Operations and chained comparisons (and, or, not)
Converts Tuple type (get and set operations)
Converts List type
Converts While Statement

foo = 0
while condition:
    foo = foo + 2

Converts If, elif, else Statements

if condition1:
    foo = 0
elif condition2:
    foo = 1
else:
    bar = 2

Converts For Statement

for x in (1, 2, 3):
    ...

Converts Function Call

def Main(num: int):
    a = foo(num)
    ...

def foo(num: int) -> int:
    ...

Converts len() for str, tuple and list
Converts Multiple Expressions in the same line (i = i + h; a = 1; b = 3 + a; count = 0)
Converts String Slicing (x = 'example'[2:4], x = 'example'[:4], x = 'example'[4:], x = 'example'[:])

What it will do…

continue, break and pass
Convert Numeric Arithmetic Augmented assignment Operators (/=)
Convert Number Arithmetic Operations (/, **)
Convert Relational Operations (is, is not)
Convert String Slicing (x = 'example'[2:4:2], x = 'example'[::2])
