Python Parser Examples

Example #1

File: test_bfparser.py Project: bivab/brainfuck

def test_parse_empty_loop():
    p = Parser('[]')
    p.parse()
    ast = p.ast
    assert len(ast.children) == 1
    loop = ast.children[0]
    assert loop.value is None

Example #2

File: test_bfparser.py Project: bivab/brainfuck

def test_non_empty_loop():
    p = Parser('[-]')
    p.parse()
    ast = p.ast
    loop = ast.children[0]
    assert loop.value is None
    assert len(loop.children) == 1
    assert loop.children[0] == AstNode('-')

Example #3

File: test_bfcompiler.py Project: bivab/brainfuck

def parse(string):
    p = Parser(string)
    p.parse()
    return p.ast

Example #4

File: test_bfparser.py Project: bivab/brainfuck

def test_parse_simple_symbols():
    for x in ['<', '>', '+', '-', '.', ',']:
        p = Parser(x)
        p.parse()
        print p.ast
        assert p.ast.children[0].value == x
