parse(self, text, filename='', debug=False)
Parses C code and returns an AST.
text:
A string containing the C source code
filename:
Name of the file being parsed (for meaningful
error messages)
debug:
Debug flag to YACC
precedence = (('left', 'LOR'), ('left', 'LAND'), ('left', 'OR'), ('left', 'XOR'), ('left', 'AND'), ('left', 'EQ', 'NE'), ('left', 'GT', 'GE', 'LT', 'LE'), ('left', 'RSHIFT', 'LSHIFT'), ('left', 'PLUS', 'MINUS'), ('left', 'TIMES', 'DIVIDE', 'MOD'))
check_output(*popenargs, timeout=None, **kwargs)
Run command with arguments and return its output.
If the exit code was non-zero it raises a CalledProcessError. The
CalledProcessError object will have the return code in the returncode
attribute and output in the output attribute.
The arguments are the same as for the Popen constructor. Example:
>>> check_output(["ls", "-l", "/dev/null"])
b'crw-rw-rw- 1 root root 1, 3 Oct 18 2007 /dev/null\n'
The stdout argument is not allowed as it is used internally.
To capture standard error in the result, use stderr=STDOUT.
>>> check_output(["/bin/sh", "-c",
... "ls -l non_existent_file ; exit 0"],
... stderr=STDOUT)
b'ls: non_existent_file: No such file or directory\n'
There is an additional optional argument, "input", allowing you to
pass a string to the subprocess's stdin. If you use this argument
you may not also use the Popen constructor's "stdin" argument, as
it too will be used internally. Example:
>>> check_output(["sed", "-e", "s/foo/bar/"],
... input=b"when in the course of fooman events\n")
b'when in the course of barman events\n'
By default, all communication is in bytes, and therefore any "input"
should be bytes, and the return value will be bytes. If in text mode,
any "input" should be a string, and the return value will be a string
decoded according to locale encoding, or by "encoding" if set. Text mode
is triggered by setting any of text, encoding, errors or universal_newlines.
parse_file(filename, use_cpp=False, cpp_path='cpp', cpp_args='', parser=None)
Parse a C file using pycparser.
filename:
Name of the file you want to parse.
use_cpp:
Set to True if you want to execute the C pre-processor
on the file prior to parsing it.
cpp_path:
If use_cpp is True, this is the path to 'cpp' on your
system. If no path is provided, it attempts to just
execute 'cpp', so it must be in your PATH.
cpp_args:
If use_cpp is True, set this to the command line arguments strings
to cpp. Be careful with quotes - it's best to pass a raw string
(r'') here. For example:
r'-I../utils/fake_libc_include'
If several arguments are required, pass a list of strings.
parser:
Optional parser object to be used instead of the default CParser
When successful, an AST is returned. ParseError can be
thrown if the file doesn't parse successfully.
Errors from cpp will be printed out.
preprocess_file(filename, cpp_path='cpp', cpp_args='')
Preprocess a file using cpp.
filename:
Name of the file you want to preprocess.
cpp_path:
cpp_args:
Refer to the documentation of parse_file for the meaning of these
arguments.
When successful, returns the preprocessed file's contents.
Errors from cpp will be printed out.
