示例1: convert_with_2to3
# 需要導入模塊: from lib2to3.refactor import RefactoringTool [as 別名]
# 或者: from lib2to3.refactor.RefactoringTool import _read_python_source [as 別名]
def convert_with_2to3(filepath):

source = refactoring_tool._read_python_source(filepath)[0]
try:
tree = refactoring_tool.refactor_string(source, 'conf.py')
except ParseError, err:
# do not propagate lib2to3 exceptions
lineno, offset = err.context[1]
# try to match ParseError details with SyntaxError details
raise SyntaxError(err.msg, (filepath, lineno, offset, err.value))
