New submission from Łukasz Langa <luk...@langa.pl>: Overview --------
It's a fairly common need in configuration parsing to take configuration from a string or a Python data structure (most commonly, a dictionary). The attached patch introduces two new methods to RawConfigParser that serve this purpose: readstring and readdict. In the process, two behavioral bugs were detected and fixed. Detailed information about the patch ------------------------------------ Source changes: * added readstring and readdict methods * fixed a bug in SafeConfigParser.set when setting a None value would raise an exception (the code tried to remove interpolation escapes from None) * added a new exception DuplicateOptionError, raised when during parsing a single file, string or a dictionary the same option occurs twice. This catches mispellings and case-sensitivity errors (parsers are by default case-insensitive in regard to options). * added checking for option duplicates described above in _read Test changes: * self.fromstring is using readstring now * self.cf removed because it was bad design, now config parser instances are explicit everywhere ** changed definition of get_error and parse_error * split test_basic into two parts: config parser building and the actual test ** introduced config parser built from the dictionary * added a duplicate option checking case for string and dictionary based reading Documentation changes: * documented readstring and readdict * documented DuplicateOptionError * explicit remark about the case-insensitivity * corrected remark about leading whitespace being removed from values (also trailing whitespace is, and for keys as well) ---------- components: Library (Lib) messages: 112409 nosy: lukasz.langa priority: normal severity: normal status: open title: configparser support for reading from strings and dictionaries type: feature request versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9452> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
