  Maximum interpolation depth exceeded in string interpolation.

  `__init__`(option)

exception `terminatorlib.configobj.configobj.``MissingInterpolationOption`(option)

  Bases: `terminatorlib.configobj.configobj.InterpolationError`

  A value specified for interpolation was missing.

  `__init__`(option)

  Bases: `terminatorlib.configobj.configobj.ConfigObjError`

  This error indicates additional sections in a section with a `__many__` (repeated) section.

exception `terminatorlib.configobj.configobj.``ReloadError`

  Bases: `exceptions.IOError`

  A ‘reload’ operation failed. This exception is a subclass of `IOError`.

  `__init__`()

exception `terminatorlib.configobj.configobj.``UnreprError`(message='', line_number=None, line='')

  Bases: `terminatorlib.configobj.configobj.ConfigObjError`

  An error parsing in unrepr mode.

exception `terminatorlib.configobj.configobj.``UnknownType`

  Bases: `exceptions.Exception`

class `terminatorlib.configobj.configobj.``ConfigObj`(infile=None, options=None, configspec=None, encoding=None, interpolation=True, raise_errors=False, list_values=True, create_empty=False, file_error=False, stringify=True, indent_type=None, default_encoding=None, unrepr=False, write_empty_values=False, _inspec=False)

  Bases: `terminatorlib.configobj.configobj.Section`

  An object to read, create, and write config files.

  `__init__`(infile=None, options=None, configspec=None, encoding=None, interpolation=True, raise_errors=False, list_values=True, create_empty=False, file_error=False, stringify=True, indent_type=None, default_encoding=None, unrepr=False, write_empty_values=False, _inspec=False)

    Parse a config file or create a config file object.

  `__repr__`()
  `_a_to_u`(aString)

    Decode ASCII strings to unicode if a self.encoding is specified.

  `_decode`(infile, encoding)

    Decode infile to unicode. Using the specified encoding.

    if is a string, it also needs converting to a list.

  `_decode_element`(line)

    Decode element to unicode if necessary.

  `_get_single_quote`(value)
  `_get_triple_quote`(value)
  `_handle_bom`(infile)

    Handle any BOM, and decode if necessary.

    If an encoding is specified, that must be used - but the BOM should still be removed (and the BOM attribute set).

    (If the encoding is wrongly specified, then a BOM for an alternative encoding won’t be discovered or removed.)

    If an encoding is not specified, UTF8 or UTF16 BOM will be detected and removed. The BOM attribute will be set. UTF16 will be decoded to unicode.

    NOTE: This method must not be called with an empty `infile`.

    Specifying the wrong encoding is likely to cause a `UnicodeDecodeError`.

    `infile` must always be returned as a list of lines, but may be passed in as a single string.

  `_handle_comment`(comment)

    Deal with a comment.

  `_handle_configspec`(configspec)

    Parse the configspec.

  `_handle_error`(text, ErrorClass, infile, cur_index)

    Handle an error according to the error settings.

    Either raise the error or store it. The error will have occured at `cur_index`

  `_handle_value`(value)

    Given a value string, unquote, remove comment, handle lists. (including empty and single member lists)

  `_initialise`(options=None)
  `_load`(infile, configspec)
  `_match_depth`(sect, depth)

    Given a section and a depth level, walk back through the sections parents to see if the depth level matches a previous section.

    Return a reference to the right section, or raise a SyntaxError.

  `_multiline`(value, infile, cur_index, maxline)

    Extract the value, where we are in a multiline situation.

  `_parse`(infile)

    Actually parse the config file.

  `_quote`(value, multiline=True)

    Return a safely quoted version of a value.

    Raise a ConfigObjError if the value cannot be safely quoted. If multiline is `True` (default) then use triple quotes if necessary.

    - Don’t quote values that don’t need it.
    - Recursively quote members of a list and return a comma joined list.
    - Multiline is `False` for lists.
    - Obey list syntax for empty and single member lists.

    If `list_values=False` then the value is only quoted if it contains a `\n` (is multiline) or ‘#’.

    If `write_empty_values` is set, and the value is an empty string, it won’t be quoted.

  `_set_configspec`(section, copy)

    Called by validate. Handles setting the configspec on subsections including sections to be validated by __many__

  `_str`(value)

    Used by `stringify` within validate, to turn non-string values into strings.

  `_unquote`(value)

    Return an unquoted version of a value

  `_write_line`(indent_string, entry, this_entry, comment)

    Write an individual line, for the write method

  `_write_marker`(indent_string, depth, entry, comment)

    Write a section marker line

  `reload`()

    Reload a ConfigObj from file.

    This method raises a `ReloadError` if the ConfigObj doesn’t have a filename attribute pointing to a file.

  `reset`()

    Clear ConfigObj instance and restore to ‘freshly created’ state.

  `validate`(validator, preserve_errors=False, copy=False, section=None)

    Test the ConfigObj against a configspec.

    It uses the `validator` object from validate.py.

    To run `validate` on the current ConfigObj, call:

        test = config.validate(validator)

    (Normally having previously passed in the configspec when the ConfigObj was created - you can dynamically assign a dictionary of checks to the `configspec` attribute of a section though).

    It returns `True` if everything passes, or a dictionary of pass/fails (True/False). If every member of a subsection passes, it will just have the value `True`. (It also returns `False` if all members fail).

    In addition, it converts the values from strings to their native types if their checks pass (and `stringify` is set).

    If `preserve_errors` is `True` (`False` is default) then instead of a marking a fail with a `False`, it will preserve the actual exception object. This can contain info about the reason for failure. For example the `VdtValueTooSmallError` indicates that the value supplied was too small. If a value (or section) is missing it will still be marked as `False`.

    You must have the validate module to use `preserve_errors=True`.

    You can then use the `flatten_errors` function to turn your nested results dictionary into a flattened list of failures - useful for displaying meaningful error messages.

  `write`(outfile=None, section=None)

    Write the current ConfigObj as a file

    tekNico: FIXME: use StringIO instead of real files

        >>> filename = a.filename
        >>> a.filename = 'test.ini'
        >>> a.write()

class `terminatorlib.configobj.configobj.``SimpleVal`

  Bases: `object`

  A simple validator. Can be used to check that all members expected are present.

  To use it, provide a configspec with all your members in (the value given will be ignored). Pass an instance of `SimpleVal` to the `validate` method of your `ConfigObj`. `validate` will return `True` if all members are present, or a dictionary with True/False meaning present/missing. (Whole missing sections will be replaced with `False`)

  `__init__`()
  `check`(check, member, missing=False)

    A dummy check method, always returns the value unchanged.

`terminatorlib.configobj.configobj.``flatten_errors`(cfg, res, levels=None, results=None)

  An example function that will turn a nested dictionary of results (as returned by `ConfigObj.validate`) into a flat list.

  `cfg` is the ConfigObj instance being checked, `res` is the results dictionary returned by `validate`.

  (This is a recursive function, so you shouldn’t use the `levels` or `results` arguments - they are used by the function.)

  Returns a list of keys that failed. Each member of the list is a tuple:

      ([list of sections...], key, result)

  If `validate` was called with `preserve_errors=False` (the default) then `result` will always be `False`.

  list of sections is a flattened list of sections that the key was found in.

  If the section was missing (or a section was expected and a scalar provided - or vice-versa) then key will be `None`.

  If the value (or section) was missing then `result` will be `False`.

  If `validate` was called with `preserve_errors=True` and a value was present, but failed the check, then `result` will be the exception object returned. You can use this as a string that describes the failure.

  For example The value “3” is of the wrong type.

`terminatorlib.configobj.configobj.``get_extra_values`(conf, _prepend=())

  Find all the values and sections not in the configspec from a validated ConfigObj.

  `get_extra_values` returns a list of tuples where each tuple represents either an extra section, or an extra value.

  The tuples contain two values, a tuple representing the section the value is in and the name of the extra values. For extra values in the top level section the first member will be an empty tuple. For values in the ‘foo’ section the first member will be `('foo',)`. For members in the ‘bar’ subsection of the ‘foo’ section the first member will be `('foo', 'bar')`.

  NOTE: If you call `get_extra_values` on a ConfigObj instance that hasn’t been validated it will return an empty list.

## terminatorlib.configobj.validate module

The Validator object is used to check that supplied values conform to a specification.

The value can be supplied as a string - e.g. from a config file. In this case the check will also convert the value to the required type. This allows you to add validation as a transparent layer to access data stored as strings. The validation checks that the data is correct and converts it to the expected type.

Some standard checks are provided for basic data types. Additional checks are easy to write. They can be provided when the `Validator` is instantiated or added afterwards.

The standard functions work with the following basic data types :

- integers
- floats
- booleans
- strings
- ip_addr

plus lists of these datatypes

Adding additional checks is done through coding simple functions.

The full set of standard checks are :

- ‘integer’: matches integer values (including negative)

    Takes optional ‘min’ and ‘max’ arguments :

        integer()
        integer(3, 9)  # any value from 3 to 9
        integer(min=0) # any positive value
        integer(max=9)

- ‘float’: matches float values

    Has the same parameters as the integer check.

- ‘boolean’: matches boolean values - `True` or `False`
    Acceptable string values for True are :

      true, on, yes, 1

    Acceptable string values for False are :

      false, off, no, 0

    Any other value raises an error.

- ‘ip_addr’: matches an Internet Protocol address, v.4, represented

    by a dotted-quad string, i.e. ‘1.2.3.4’.

- ‘string’: matches any string.

    Takes optional keyword args ‘min’ and ‘max’ to specify min and max lengths of the string.

- ‘list’: matches any list.

    Takes optional keyword args ‘min’, and ‘max’ to specify min and max sizes of the list. (Always returns a list.)

- ‘tuple’: matches any tuple.

    Takes optional keyword args ‘min’, and ‘max’ to specify min and max sizes of the tuple. (Always returns a tuple.)

- ‘int_list’: Matches a list of integers.

    Takes the same arguments as list.

- ‘float_list’: Matches a list of floats.

    Takes the same arguments as list.

- ‘bool_list’: Matches a list of boolean values.

    Takes the same arguments as list.

- ‘ip_addr_list’: Matches a list of IP addresses.

    Takes the same arguments as list.

- ‘string_list’: Matches a list of strings.

    Takes the same arguments as list.

- ‘mixed_list’: Matches a list with different types in

    specific positions. List size must match the number of arguments.

    Each position can be one of : ‘integer’, ‘float’, ‘ip_addr’, ‘string’, ‘boolean’

    So to specify a list with two strings followed by two integers, you write the check as :

        mixed_list('string', 'string', 'integer', 'integer')

- ‘pass’: This check matches everything ! It never fails

    and the value is unchanged.

    It is also the default if no check is specified.

- ‘option’: This check matches any from a list of options.

    You specify this check with :

        option('option 1', 'option 2', 'option 3')

You can supply a default value (returned if no value is supplied) using the default keyword argument.

You specify a list argument for default using a list constructor syntax in the check :

    checkname(arg1, arg2, default=list('val 1', 'val 2', 'val 3'))

A badly formatted set of arguments will raise a `VdtParamError`.

exception `terminatorlib.configobj.validate.``ValidateError`

  Bases: `exceptions.Exception`

  This error indicates that the check failed. It can be the base class for more specific errors.

exception `terminatorlib.configobj.validate.``VdtMissingValue`

  Bases: `terminatorlib.configobj.validate.ValidateError`

  No value was supplied to a check that needed one.

class `terminatorlib.configobj.validate.``Validator`(functions=None)

  Bases: `object`

  Validator is an object that allows you to register a set of ‘checks’. These checks take input and test that it conforms to the check.

  This can also involve converting the value from a string into the correct datatype.

  The `check` method takes an input string which configures which check is to be used and applies that check to a supplied value.

  An example input string would be: ‘int_range(param1, param2)’

  You would then provide something like:

      >>> def int_range_check(value, min, max):
      ...     # turn min and max from strings to integers
      ...     min = int(min)
      ...     max = int(max)
      ...     # check that value is of the correct type.
      ...     # possible valid inputs are integers or strings
      ...     # that represent integers
      ...     if not isinstance(value, (int, long, basestring)):
      ...         raise VdtTypeError(value)
      ...     elif isinstance(value, basestring):
      ...         # if we are given a string
      ...         # attempt to convert to an integer
      ...         try:
      ...             value = int(value)
      ...         except ValueError:
      ...             raise VdtValueError(value)
      ...     # check the value is between our constraints
      ...     if not min <= value:
      ...          raise VdtValueTooSmallError(value)
      ...     if not value <= max:
      ...          raise VdtValueTooBigError(value)
      ...     return value
      ...
      >>> fdict = {'int_range': int_range_check}
      >>> vtr1 = Validator(fdict)
      >>> vtr1.check('int_range(20, 40)', '30')
      30
      >>> vtr1.check('int_range(20, 40)', '60')
      Traceback (most recent call last):
      VdtValueTooBigError: the value "60" is too big.

  New functions can be added with :

      >>> vtr2 = Validator()
      >>> vtr2.functions['int_range'] = int_range_check

  Or by passing in a dictionary of functions when Validator is instantiated.

  Your functions can use keyword arguments, but the first argument should always be ‘value’.

  If the function doesn’t take additional arguments, the parentheses are optional in the check. It can be written with either of :

      keyword = function_name
      keyword = function_name()

  The first program to utilise Validator() was Michael Foord’s ConfigObj, an alternative to ConfigParser which supports lists and can validate a config file using a config schema. For more details on using Validator with ConfigObj see: http://www.voidspace.org.uk/python/configobj.html

  `__init__`(functions=None)

        >>> vtri = Validator()

  `_check_value`(value, fun_name, fun_args, fun_kwargs)
  `_handle_none`(value)
  `_list_handle`(listmatch)

    Take apart a `keyword=list('val, 'val')` type string.

  `_parse_check`(check)
  `_parse_with_caching`(check)
  `_pass`(value)

    Dummy check that always passes

        >>> vtor.check('', 0)
        0
        >>> vtor.check('', '0')
        '0'

  `_unquote`(val)

    Unquote a value if necessary.

  `check`(check, value, missing=False)

    Usage: check(check, value)

    Arguments:
      check: string representing check to apply (including arguments) value: object to be checked

    Returns value, converted to correct type if necessary

    If the check fails, raises a `ValidateError` subclass.

        >>> vtor.check('yoda', '')
        Traceback (most recent call last):
        VdtUnknownCheckError: the check "yoda" is unknown.
        >>> vtor.check('yoda()', '')
        Traceback (most recent call last):
        VdtUnknownCheckError: the check "yoda" is unknown.

        >>> vtor.check('string(default="")', '', missing=True)
        ''

  `get_default_value`(check)

    Given a check, return the default value for the check (converted to the right type).

    If the check doesn’t specify a default value then a `KeyError` will be raised.

`terminatorlib.configobj.validate.``is_integer`(value, min=None, max=None)

  A check that tests that a given value is an integer (int, or long) and optionally, between bounds. A negative value is accepted, while a float will fail.

  If the value is a string, then the conversion is done - if possible. Otherwise a VdtError is raised.

      >>> vtor.check('integer', '-1')

`terminatorlib.configobj.validate.``is_float`(value, min=None, max=None)

  A check that tests that a given value is a float (an integer will be accepted), and optionally - that it is between bounds.

  If the value is a string, then the conversion is done - if possible. Otherwise a VdtError is raised.

  This can accept negative values.

      >>> vtor.check('float', '2')
      2.0

  From now on we multiply the value to avoid comparing decimals

      >>> vtor.check('float', '-6.8') * 10
      -68.0
      >>> vtor.check('float', '12.2') * 10
      122.0
      >>> vtor.check('float', 8.4) * 10
      84.0
      >>> vtor.check('float', 'a')
      Traceback (most recent call last):
      VdtTypeError: the value "a" is of the wrong type.

      102.0
      >>> vtor.check('float(max=20.2)', '15.1') * 10
      151.0
      >>> vtor.check('float(10.0)', '9.0')
      Traceback (most recent call last):
      VdtValueTooSmallError: the value "9.0" is too small.
      >>> vtor.check('float(max=20.0)', '35.0')

`terminatorlib.configobj.validate.``is_mixed_list`(value, *args)

  Check that the value is a list. Allow specifying the type of each member. Work on lists of specific lengths.

  You specify each member as a positional argument specifying type

  Each type should be one of the following strings :
    ‘integer’, ‘float’, ‘ip_addr’, ‘string’, ‘boolean’

  So you can specify a list of two strings, followed by two integers as :

  > mixed_list(‘string’, ‘string’, ‘integer’, ‘integer’)

  The length of the list must match the number of positional arguments you supply.

      >>> mix_str = "mixed_list('integer', 'float', 'ip_addr', 'string', 'boolean')"
      >>> check_res = vtor.check(mix_str, (1, 2.0, '1.2.3.4', 'a', True))
      >>> check_res == [1, 2.0, '1.2.3.4', 'a', True]

      >>> check_res == [1, 2.0, '1.2.3.4', 'a', True]
      1
      >>> vtor.check(mix_str, ('b', 2.0, '1.2.3.4', 'a', True))
      Traceback (most recent call last):
      VdtTypeError: the value "b" is of the wrong type.
      >>> vtor.check(mix_str, (1, 2.0, '1.2.3.4', 'a'))
      Traceback (most recent call last):
      VdtValueTooShortError: the value "(1, 2.0, '1.2.3.4', 'a')" is too short.
      >>> vtor.check(mix_str, (1, 2.0, '1.2.3.4', 'a', 1, 'b'))
      Traceback (most recent call last):
      VdtValueTooLongError: the value "(1, 2.0, '1.2.3.4', 'a', 1, 'b')" is too long.
      >>> vtor.check(mix_str, 0)
      Traceback (most recent call last):
      VdtTypeError: the value "0" is of the wrong type.

  This test requires an elaborate setup, because of a change in error string output from the interpreter between Python 2.2 and 2.3 .

      >>> res_seq = (
      ...     'passed an incorrect value "',
      ...     'yoda',
      ...     '" for parameter "mixed_list".',

      ...     vtor.check('mixed_list("yoda")', ('a'))
      ... except VdtParamError, err:
      ...     str(err) == res_str
      1

`terminatorlib.configobj.validate.``is_option`(value, *options)

  This check matches the value to any of a set of options.

      >>> vtor.check('option("yoda", "jedi")', 'yoda')
      'yoda'
      >>> vtor.check('option("yoda", "jedi")', 'jed')
      Traceback (most recent call last):
      VdtValueError: the value "jed" is unacceptable.
      >>> vtor.check('option("yoda", "jedi")', 0)
      Traceback (most recent call last):
      VdtTypeError: the value "0" is of the wrong type.
