The format of these files is as follows: globalvar = 2 [ABC] a = 1 b = abc.html c = text with spaces [DEF] a = 2 b = a + 3 c = a string Entries in square brackets indicate new subsections. Global variables may be set prior to starting any subsection. Emtpy lines and lines starting with '#' (comments) are ignored. Indentation is not necessary; lines can start at any column. Entries may span multiple lines by using '' continuations at the line ends, e.g. [Continuation] a = first line second line The lines are stripped of any white space before removing the trailing '' and concatenating them. Comment lines are removed as well. To parse these files, a template in form of a class including subclasses (identifying the subsections) must be given to the reader. This template defines which sections and attributes are known. All others are rejected. A sample template for the above looks like this: from mx.Misc.ConfigFile import * class Template(ConfigNamespace): global = IntegerEntry() class ABC(ConfigSection): a = IntegerEntry('0') b = StringEntry('default.html') c = StringEntry() class DEF(ConfigSection): a = IntegerEntry('0') b = EvalEntry('0') c = StringEntry('default value') The main class representing the global namespace of the ini file must have ConfigNamespace as baseclass. It may contain any number of ConfigSection subclasses each defining parsed attributes. The ini file may only contain entries defined in this template. In case an unkown section is found, the main class is looked up for a ConfigSection subclass with name 'DefaultSection'. This section object is then taken as template for a new section of the given name. The same feature is available for attributes in sections. In case a given attribute is not found in the templates, the section's 'DefaultAttribute' attribute is deepcopied and the used as attribute template. Needs mxTools to be installed.

Configuration file reader. Takes a template (a ConfigNamespace subclass) as input which defines sections using classes. Sections may include instances of Entry as attributes.

Section classes are replaced with ConfigSection instances. After successful reading the file, the configuration information is available through this variable.
