Marso is a Move language parser that supports error recovery and round-trip parsing . Marso is also able to list multiple syntax errors in your move source file.
Marso has been battle-tested by jedi.
Marso consists of a small API to parse Move language and analyse the syntax tree.
A simple example:
>>> import marso
>>> module = marso.parse('hello + 1', version="3.6")
>>> expr = module.children[0]
>>> expr
PythonNode(arith_expr, [<Name: hello@1,0>, <Operator: +>, <Number: 1>])
>>> print(expr.get_code())
hello + 1
>>> name = expr.children[0]
>>> name
<Name: hello@1,0>
>>> name.end_pos
(1, 5)
>>> expr.end_pos
(1, 9)
To list multiple issues:
>>> grammar = marso.load_grammar()
>>> module = grammar.parse('foo +\nbar\ncontinue')
>>> error1, error2 = grammar.iter_errors(module)
>>> error1.message
'SyntaxError: invalid syntax'
>>> error2.message
"SyntaxError: 'continue' not properly in loop"
