From a8add0ec5ef05c26e1641b8310b65ddd75c0fec3 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Mon, 14 May 2007 22:03:55 +0000 Subject: Merged revisions 55270-55324 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/p3yk ........ r55271 | fred.drake | 2007-05-11 10:14:47 -0700 (Fri, 11 May 2007) | 3 lines remove jpeg, panel libraries for SGI; there is more IRIX stuff left over, I guess that should be removed too, but will leave for someone who is sure ........ r55280 | fred.drake | 2007-05-11 19:11:37 -0700 (Fri, 11 May 2007) | 1 line remove mention of file that has been removed ........ r55301 | brett.cannon | 2007-05-13 17:38:05 -0700 (Sun, 13 May 2007) | 4 lines Remove rexec and Bastion from the stdlib. This also eliminates the need for f_restricted on frames. This in turn negates the need for PyEval_GetRestricted() and PyFrame_IsRestricted(). ........ r55303 | brett.cannon | 2007-05-13 19:22:22 -0700 (Sun, 13 May 2007) | 2 lines Remove the md5 and sha modules. ........ r55305 | george.yoshida | 2007-05-13 19:45:55 -0700 (Sun, 13 May 2007) | 2 lines fix markup ........ r55306 | neal.norwitz | 2007-05-13 19:47:57 -0700 (Sun, 13 May 2007) | 1 line Get the doc building again after some removals. ........ r55307 | neal.norwitz | 2007-05-13 19:50:45 -0700 (Sun, 13 May 2007) | 1 line Get test_pyclbr passing again after getstatus was removed from commands. This "test case" was weird since it was just importing a seemingly random module. Remove the import ........ r55322 | brett.cannon | 2007-05-14 14:09:20 -0700 (Mon, 14 May 2007) | 3 lines Remove the compiler package. Will eventually need a mechanism to byte compile an AST. ........ --- Lib/compiler/future.py | 73 -------------------------------------------------- 1 file changed, 73 deletions(-) delete mode 100644 Lib/compiler/future.py (limited to 'Lib/compiler/future.py') diff --git a/Lib/compiler/future.py b/Lib/compiler/future.py deleted file mode 100644 index 6e724904a78..00000000000 --- a/Lib/compiler/future.py +++ /dev/null @@ -1,73 +0,0 @@ -"""Parser for future statements - -""" - -from compiler import ast, walk - -def is_future(stmt): - """Return true if statement is a well-formed future statement""" - if not isinstance(stmt, ast.From): - return 0 - if stmt.modname == "__future__": - return 1 - else: - return 0 - -class FutureParser: - - features = ("nested_scopes", "generators", "division", - "absolute_import", "with_statement") - - def __init__(self): - self.found = {} # set - - def visitModule(self, node): - stmt = node.node - for s in stmt.nodes: - if not self.check_stmt(s): - break - - def check_stmt(self, stmt): - if is_future(stmt): - for name, asname in stmt.names: - if name in self.features: - self.found[name] = 1 - else: - raise SyntaxError, \ - "future feature %s is not defined" % name - stmt.valid_future = 1 - return 1 - return 0 - - def get_features(self): - """Return list of features enabled by future statements""" - return self.found.keys() - -class BadFutureParser: - """Check for invalid future statements""" - - def visitFrom(self, node): - if hasattr(node, 'valid_future'): - return - if node.modname != "__future__": - return - raise SyntaxError, "invalid future statement " + repr(node) - -def find_futures(node): - p1 = FutureParser() - p2 = BadFutureParser() - walk(node, p1) - walk(node, p2) - return p1.get_features() - -if __name__ == "__main__": - import sys - from compiler import parseFile, walk - - for file in sys.argv[1:]: - print(file) - tree = parseFile(file) - v = FutureParser() - walk(tree, v) - print(v.found) - print() -- cgit v1.2.3
