From f7f438ba3b05eb4356e7511401686b07d9dfb6d8 Mon Sep 17 00:00:00 2001 From: Thomas Wouters Date: Tue, 28 Feb 2006 16:09:29 +0000 Subject: SF patch #1438387, PEP 328: relative and absolute imports. - IMPORT_NAME takes an extra argument from the stack: the relativeness of the import. Only passed to __import__ when it's not -1. - __import__() takes an optional 5th argument for the same thing; it __defaults to -1 (old semantics: try relative, then absolute) - 'from . import name' imports name (be it module or regular attribute) from the current module's *package*. Likewise, 'from .module import name' will import name from a sibling to the current module. - Importing from outside a package is not allowed; 'from . import sys' in a toplevel module will not work, nor will 'from .. import sys' in a (single-level) package. - 'from __future__ import absolute_import' will turn on the new semantics for import and from-import: imports will be absolute, except for from-import with dots. Includes tests for regular imports and importhooks, parser changes and a NEWS item, but no compiler-package changes or documentation changes. --- Python/future.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'Python/future.c') diff --git a/Python/future.c b/Python/future.c index da56dfb14c..0a87b10066 100644 --- a/Python/future.c +++ b/Python/future.c @@ -29,6 +29,8 @@ future_check_features(PyFutureFeatures *ff, stmt_ty s, const char *filename) continue; } else if (strcmp(feature, FUTURE_DIVISION) == 0) { ff->ff_features |= CO_FUTURE_DIVISION; + } else if (strcmp(feature, FUTURE_ABSIMPORT) == 0) { + ff->ff_features |= CO_FUTURE_ABSIMPORT; } else if (strcmp(feature, "braces") == 0) { PyErr_SetString(PyExc_SyntaxError, "not a chance"); -- cgit v1.2.1
