Dotconf Description

Dotconf is an advanced configuration parser which allow nested sections to any level, typed values in syntax, file include and so more. It is also shipped with a powerful schema validation system.ExampleThis is an example of configuration file for an imaginary web server:daemon = Truepidfile = '/var/run/myapp.pid'interface = '0.0.0.0:80'interface_ssl = '0.0.0.0:443'host 'example.org' { path '/' { rate_limit = 30 }}host 'protected.example.org' { enable_ssl = yes path '/files' { enable_auth = yes user 'foo' { password = 'bar' } }}You can access to each values using the developer friendly API:>>> from dotconf import Dotconf>>> parsed_conf = Dotconf.from_file('mywebserver.conf')>>> print parsed_conf.get('daemon', False)TrueEven more exciting, you can create a validation schema to avoid you the painful chore of manual configuration file validation:from dotconf.schema import many, oncefrom dotconf.schema.containers import Section, Valuefrom dotconf.schema.types import Boolean, Integer, Float, String# Schema definition:class UserSection(Section): password = Value(String()) _meta = {'repeat': many, 'unique': True}class PathSection(Section): rate_limit = Value(Float(), default=0) enable_auth = Value(Boolean(), default=False) user = UserSection()class VirtualHostSection(Section): base_path = Value(String()) enable_ssl = Value(Boolean(), default=False) path = PathSection() _meta = {'repeat': many, 'unique': True}class MyWebserverConfiguration(Section): daemon = Value(Boolean()default=False) pidfile = Value(String(), default=None) interface = Value(String(), default='127.0.0.1:80') interface_ssl = Value(String(), default='127.0.0.1:443') host = VirtualHostSection()Then you can use the API exactly as if it was not validated:>>> from dotconf import Dotconf>>> from myconfschema import MyWebserverConfiguration>>> parsed_conf = Dotconf(conf, schema=MyWebserverConfiguration)>>> print 'daemon:', parsed_conf.get('daemon')daemon: True>>> for vhost in parsed_conf.subsections('host'):>>> print vhost.args>>> if vhost.get('enable_ssl'):>>> print ' SSL enabled'>>> for path in vhost.subsections('path'):>>> print ' ' + path.args>>> if path.get('enable_auth'):>>> print ' Following users can access to this directory:'>>> for user in path.subsections('user'):>>> print ' - ' + user.args>>>example.org /protected.example.org SSL enabled /files Following users can access to this directory: - fooProduct's homepage
