"""Configuration file parser.
|
||||||
|
|
||||||
|
A setup file consists of sections, lead by a "[section]" header,
|
||||||
|
and followed by "name: value" entries, with continuations and such in
|
||||||
|
the style of rfc822.
|
||||||
|
|
||||||
|
The option values can contain format strings which refer to other
|
||||||
|
values in the same section, or values in a special [DEFAULT] section.
|
||||||
|
For example:
|
||||||
|
|
||||||
|
something: %(dir)s/whatever
|
||||||
|
|
||||||
|
would resolve the "%(dir)s" to the value of dir. All reference
|
||||||
|
expansions are done late, on demand.
|
||||||
|
|
||||||
|
Intrinsic defaults can be specified by passing them into the
|
||||||
|
ConfigParser constructor as a dictionary.
|
||||||
|
|
||||||
|
class:
|
||||||
|
|
||||||
|
ConfigParser -- responsible for for parsing a list of
|
||||||
|
configuration files, and managing the parsed database.
|
||||||
|
|
||||||
|
methods:
|
||||||
|
|
||||||
|
__init__(defaults=None) -- create the parser and specify a
|
||||||
|
dictionary of intrinsic defaults. The
|
||||||
|
keys must be strings, the values must
|
||||||
|
be appropriate for %()s string
|
||||||
|
interpolation. Note that `name' is
|
||||||
|
always an intrinsic default; it's value
|
||||||
|
is the section's name.
|
||||||
|
|
||||||
|
sections() -- return all the configuration section names, sans DEFAULT
|
||||||
|
|
||||||
|
options(section) -- return list of configuration options for the named
|
||||||
|
section
|
||||||
|
|
||||||
|
read(*filenames) -- read and parse the list of named configuration files
|
||||||
|
|
||||||
|
get(section, option, raw=0) -- return a string value for the named
|
||||||
|
option. All % interpolations are
|
||||||
|
expanded in the return values, based on
|
||||||
|
the defaults passed into the constructor
|
||||||
|
and the DEFAULT section.
|
||||||
|
|
||||||
|
getint(section, options) -- like get(), but convert value to an integer
|
||||||
|
|
||||||
|
getfloat(section, options) -- like get(), but convert value to a float
|
||||||
|
|
||||||
|
getboolean(section, options) -- like get(), but convert value to
|
||||||
|
a boolean (currently defined as 0
|
||||||
|
or 1, only)
