我们从Python开源项目中，提取了以下13个代码示例，用于说明如何使用pydoc.apropos()。
def test_apropos_with_bad_package(self): # Issue 7425 - pydoc -k failed when bad package on path pkgdir = os.path.join(TESTFN, "syntaxerr") os.mkdir(pkgdir) badsyntax = os.path.join(pkgdir, "__init__") + os.extsep + "py" with open(badsyntax, 'w') as f: f.write("invalid python syntax = $1\n") with self.restrict_walk_packages(path=[TESTFN]): with captured_stdout() as out: with captured_stderr() as err: pydoc.apropos('xyzzy') # No result, no error self.assertEqual(out.getvalue(), '') self.assertEqual(err.getvalue(), '') # The package name is still matched with captured_stdout() as out: with captured_stderr() as err: pydoc.apropos('syntaxerr') self.assertEqual(out.getvalue().strip(), 'syntaxerr') self.assertEqual(err.getvalue(), '')
def test_apropos_with_unreadable_dir(self): # Issue 7367 - pydoc -k failed when unreadable dir on path self.unreadable_dir = os.path.join(TESTFN, "unreadable") os.mkdir(self.unreadable_dir, 0) self.addCleanup(os.rmdir, self.unreadable_dir) # Note, on Windows the directory appears to be still # readable so this is not really testing the issue there with self.restrict_walk_packages(path=[TESTFN]): with captured_stdout() as out: with captured_stderr() as err: pydoc.apropos('SOMEKEY') # No result, no error self.assertEqual(out.getvalue(), '') self.assertEqual(err.getvalue(), '')
def test_apropos_empty_doc(self): pkgdir = os.path.join(TESTFN, 'walkpkg') os.mkdir(pkgdir) self.addCleanup(rmtree, pkgdir) init_path = os.path.join(pkgdir, '__init__.py') with open(init_path, 'w') as fobj: fobj.write("foo = 1") current_mode = stat.S_IMODE(os.stat(pkgdir).st_mode) try: os.chmod(pkgdir, current_mode & ~stat.S_IEXEC) with self.restrict_walk_packages(path=[TESTFN]), captured_stdout() as stdout: pydoc.apropos('') self.assertIn('walkpkg', stdout.getvalue()) finally: os.chmod(pkgdir, current_mode)
