Ⅰ. Utilitas baris perintah untuk menanyakan AST Python menggunakan sintaks XPath.

ⅠⅠ. Cara yang lebih baik untuk menelusuri basis kode Anda.

Contoh penggunaan

Menemukan semua penggunaan eval bawaan:

$ astpath " .//Call/func/Name[@id='eval'] " | head -5
./rlcompleter.py:136    >            thisobject = eval(expr, self.namespace)
./warnings.py:176       >            cat = eval(category)
./rexec.py:328  >        return eval(code, m.__dict__)
./pdb.py:387    >                    func = eval(arg,
./pdb.py:760    >            return eval(arg, self.curframe.f_globals,

Menemukan semua nomor:

$ astpath " .//Num " | head -5
./DocXMLRPCServer.py:31 >        here = 0
./DocXMLRPCServer.py:41 >        while 1:
./DocXMLRPCServer.py:57 >            elif text[end:end+1] == ' ( ' :
./DocXMLRPCServer.py:82 >                    args[1:],
./DocXMLRPCServer.py:96 >            argspec = object[0] or argspec

... yang tidak pernah ditetapkan ke variabel:

$ astpath " .//Num[not(ancestor::Assign)] " | head -5
./DocXMLRPCServer.py:41 >        while 1:
./DocXMLRPCServer.py:57 >            elif text[end:end+1] == ' ( ' :
./DocXMLRPCServer.py:201        >                assert 0, " Could not find method in self.functions and no " 
./DocXMLRPCServer.py:237        >        self.send_response(200)
./DocXMLRPCServer.py:252        >                 logRequests=1, allow_none=False, encoding=None,

... dan lebih besar dari 1000:

$ astpath " .//Num[not(ancestor::Assign) and number(@n) > 1000] " | head -5
./decimal.py:959      >                    return 314159
./fractions.py:206    >    def limit_denominator(self, max_denominator=1000000):
./pty.py:138  >    return os.read(fd, 1024)
./whichdb.py:94       >    if magic in (0x13579ace, 0x13579acd, 0x13579acf):
./whichdb.py:94       >    if magic in (0x13579ace, 0x13579acd, 0x13579acf):

Menemukan nama yang lebih panjang dari 42 karakter:

$ astpath " //Name[string-length(@id) > 42] "
./site-packages/setuptools/dist.py:59   >_patch_distribution_metadata_write_pkg_info ()
./site-packages/setuptools/command/easy_install.py:1759 >        updater=clear_and_remove_cached_zip_archive_directory_data)
./test/test_reprlib.py:268      >        module = areallylongpackageandmodulenametotestreprtruncation
./test/test_argparse.py:2744    >    MEPBase, TestMutuallyExclusiveOptionalsAndPositionalsMixed):

Menemukan klausa except yang memunculkan kelas pengecualian berbeda dari yang mereka tangkap:

$ astpath " //ExceptHandler[body//Raise/exc//Name and not(contains(body//Raise/exc//Name/@id, type/Name/@id))] " | head -5
./hashlib.py:144        > except ImportError:
./plistlib.py:89        >        except KeyError:
./plistlib.py:103       >        except KeyError:
./nntplib.py:868        >        except ValueError:
./argparse.py:1116      >        except KeyError:

Menemukan awal dari blok kode yang tidak dapat dijangkau:

$ astpath " //body/*[preceding-sibling::Return or preceding-sibling::Raise][1] "
./unittest/test/testmock/testhelpers.py:381     >        class Foo(object):
./test/test_deque.py:16 >    yield 1
./test/test_posix.py:728        >            def _create_and_do_getcwd(dirname, current_path_length = 0):

Mencari calon pengganti dengan sum :

$ astpath -A 1 " //For/body[AugAssign/op/Add and count(child::*)=1] " | head -6
./functools.py:374      >        for item in sorted_items:
./functools.py:375                   key += item
./statistics.py:177     >    for d, n in sorted(partials.items ()):
./statistics.py:178              total += Fraction(n, d)
./pstats.py:512 >    for calls in callers.values ():
./pstats.py:513          nc += calls

Menemukan kelas yang cocok dengan ekspresi reguler:

$ astpath " //ClassDef[re:match('.*Var', @name)] " | head -5
./typing.py:452  >      class TypeVar(_TypingBase, _root=True):
./typing.py:1366 >      class _ClassVar(_FinalTypingBase, _root=True):
./tkinter/__init__.py:287  >    class Variable:
./tkinter/__init__.py:463  >    class StringVar(Variable):
./tkinter/__init__.py:485  >    class IntVar(Variable):

astpath juga dapat diimpor dan digunakan secara terprogram:

 >> > from astpath import search
>> > len ( search ( '.' , '//Print' , print_matches = False ))  # number of print statements in the codebase

Instalasi

Direkomendasikan agar astpath diinstal dengan ketergantungan lxml opsional, untuk memungkinkan penggunaan penuh bahasa kueri XPath. Untuk melakukannya,
