object --+ | dict --+ | Section
A dictionary-like object that represents a section in a config file.
It does string interpolation if the 'interpolation' attribute of the 'main' object is set to True.
Interpolation is tried first from this object, then from the 'DEFAULT' section of this object, next from the parent and its 'DEFAULT' section, and so on until the main object is reached.
A Section will behave like an ordered dictionary - following the order of the scalars and sections attributes. You can use this to change the order of members.
Iteration follows the order: scalars, then sections.

Correctly set a value. Making dictionary values Section instances. (We have to special case 'Section' instances - which are also dicts) Keys must be strings. Values need only be strings (or lists of strings) if main.stringify is set.

A version of clear that also affects scalars/sections Also clears comments and configspec.

Return a deepcopy of self as a dictionary. All members that are Section instances are recursively turned to ordinary dictionaries - by calling their dict method. >>> n = a.dict() >>> n == a 1 >>> n is a 0 |
Change a keyname to another, without changing position in sequence. Implemented so that transformations can be made on keys, as well as on values. (used by encode and decode) Also renames comments. |
Walk every member and call a function on the keyword and value. Return a dictionary of the return values If the function raises an exception, raise the errror unless raise_errors=False, in which case set the return value to False. Any unrecognised keyword arguments you pass to walk, will be pased on to the function you pass in. Note: if call_on_sections is True then - on encountering a subsection, first the function is called for the whole subsection, and then recurses into it's members. This means your function must be able to handle strings, dictionaries and lists. This allows you to change the key of subsections as well as for ordinary members. The return value when called on the whole subsection has to be discarded. See the encode and decode methods for examples, including functions. Caution You can use walk to transform the names of members of a section but you mustn't add or delete members. >>> config = '''[XXXXsection] ... XXXXkey = XXXXvalue'''.splitlines() >>> cfg = ConfigObj(config) >>> cfg {'XXXXsection': {'XXXXkey': 'XXXXvalue'}} >>> def transform(section, key): ... val = section[key] ... newkey = key.replace('XXXX', 'CLIENT1') ... section.rename(key, newkey) ... if isinstance(val, (tuple, list, dict)): ... pass ... else: ... val = val.replace('XXXX', 'CLIENT1') ... section[newkey] = val >>> cfg.walk(transform, call_on_sections=True) {'CLIENT1section': {'CLIENT1key': None}} >>> cfg {'CLIENT1section': {'CLIENT1key': 'CLIENT1value'}} |
Decode all strings and values to unicode, using the specified encoding. Works with subsections and list values. Uses the walk method. Testing encode and decode. >>> m = ConfigObj(a) >>> m.decode('ascii') >>> def testuni(val): ... for entry in val: ... if not isinstance(entry, unicode): ... print >> sys.stderr, type(entry) ... raise AssertionError, 'decode failed.' ... if isinstance(val[entry], dict): ... testuni(val[entry]) ... elif not isinstance(val[entry], unicode): ... raise AssertionError, 'decode failed.' >>> testuni(m) >>> m.encode('ascii') >>> a == m 1 |
Encode all strings and values from unicode, using the specified encoding. Works with subsections and list values. Uses the walk method. |
Accepts a key as input. The corresponding value must be a string or the objects (True or 1) or (False or 0). We allow 0 and 1 to retain compatibility with Python 2.2. If the string is one of True, On, Yes, or 1 it returns True. If the string is one of False, Off, No, or 0 it returns False. as_bool is not case sensitive. Any other input will raise a ValueError. >>> a = ConfigObj() >>> a['a'] = 'fish' >>> a.as_bool('a') Traceback (most recent call last): ValueError: Value "fish" is neither True nor False >>> a['b'] = 'True' >>> a.as_bool('b') 1 >>> a['b'] = 'off' >>> a.as_bool('b') 0 |
A convenience method which coerces the specified value to an integer. If the value is an invalid literal for int, a ValueError will be raised. >>> a = ConfigObj() >>> a['a'] = 'fish' >>> a.as_int('a') Traceback (most recent call last): ValueError: invalid literal for int(): fish >>> a['b'] = '1' >>> a.as_int('b') 1 >>> a['b'] = '3.2' >>> a.as_int('b') Traceback (most recent call last): ValueError: invalid literal for int(): 3.2 |
A convenience method which coerces the specified value to a float. If the value is an invalid literal for float, a ValueError will be raised. >>> a = ConfigObj() >>> a['a'] = 'fish' >>> a.as_float('a') Traceback (most recent call last): ValueError: invalid literal for float(): fish >>> a['b'] = '1' >>> a.as_float('b') 1.0 >>> a['b'] = '3.2' >>> a.as_float('b') 3.2000000000000002 |
Restore (and return) default value for the specified key. This method will only work for a ConfigObj that was created with a configspec and has been validated. If there is no default value for this key, KeyError is raised. |
Recursively restore default values to all members that have them. This method will only work for a ConfigObj that was created with a configspec and has been validated. It doesn't delete or modify entries without default values. |
