Two concrete implementations are included: BasicConfig and INIConfig. Each is described in detail elsewhere. However, here's an example of the capabilities available: Create config namespace and populate it: >>> n = BasicConfig() >>> n.playlist.expand_playlist = True >>> n.ui.display_clock = True >>> n.ui.display_qlength = True >>> n.ui.width = 150 Examine data: >>> print n.playlist.expand_playlist True >>> print n['ui']['width'] 150 >>> print n playlist.expand_playlist = True ui.display_clock = True ui.display_qlength = True ui.width = 150 Delete items: >>> del n.playlist >>> print n ui.display_clock = True ui.display_qlength = True ui.width = 150 Convert it to ini format: >>> from iniparse import ini >>> i = ini.INIConfig() >>> i.import_config(n) >>> print i [ui] display_clock = True display_qlength = True width = 150 t ConfigNamespacec B sY t Z d „ Z d „ Z d „ Z d „ Z d „ Z d „ Z d „ Z d „ Z d „ Z RS( Nc C s t | ƒ S( N( t NotImplementedErrort key( t selfR ( ( t3 /usr/lib/python2.4/site-packages/iniparse/config.pyt __getitem__@ s c C s t | | ƒ ‚ d S( N( R R t value( R R R ( ( R t __setitem__C s c C s t | ƒ ‚ d S( N( R R ( R R ( ( R t __delitem__F s c C s t ƒ S( N( R ( R ( ( R t __iter__I s c C s t | ƒ ‚ d S( N( R t name( R R ( ( R t new_namespaceL s c C s8 y | i | ƒ SWn t j o t | | ƒ Sn Xd S( N( R R R t KeyErrort Undefined( R R ( ( R t __getattr__O s c C sU y+ t i | | ƒ t i | | | ƒ d SWn# t j o | i | | ƒ n Xd S( N( t objectt __getattribute__R R t __setattr__R t AttributeErrorR ( R R R ( ( R R U s c C sK y$ t i | | ƒ t i | | ƒ Wn t j o | i | ƒ n Xd S( N( R R R R t __delattr__R R ( R R ( ( R R ] s c C s x– | D]Ž } | | } t | t ƒ od y. | | } t | t ƒ p t d ƒ ‚ n Wn" t j o | i | ƒ } n X| i | ƒ q | | | <q Wd S( Ns value-namespace conflict( t nsR R t isinstanceR R t mynst TypeErrorR R t import_config( R R R R R ( ( R R d s ( t __name__t __module__R R R R R R R R R ( ( ( R R ? s R c B s t Z d Z d „ Z d „ Z RS( s Helper class used to hold undefined names until assignment. This class helps create any undefined subsections when an assignment is made to a nested value.

The default iterator returns the names of values (i.e. keys). >>> l = list(n) >>> l.sort() >>> l ['name', 'x'] Values can be deleted using 'del' and printed using 'print'. >>> n.aaa = 42 >>> del n.x >>> print n aaa = 42 name.first = paramjit name.last = oberoi Nested namepsaces are also namespaces: >>> isinstance(n.name, ConfigNamespace) True >>> print n.name first = paramjit last = oberoi Finally, values can be read from a file as follows: >>> from StringIO import StringIO >>> sio = StringIO(''' ... # comment ... ui.height = 100 ... ui.width = 150 ... complexity = medium ... have_python ... data.secret.password = goodness=gracious me ... ''') >>> n = BasicConfig() >>> n.readfp(sio) >>> print n complexity = medium data.secret.password = goodness=gracious me have_python ui.height = 100 ui.width = 150 c C s h | _ d S( N( R t _data( R ( ( R R Ì s c C s | i | S( N( R R R ( R R ( ( R R Ï s c C s | | i | <d S( N( R R R R ( R R R ( ( R R Ò s c C s | i | =d S( N( R R R ( R R ( ( R R Õ s c C s t | i ƒ S( N( t iterR R ( R ( ( R R Ø s t c C sà g } | i i ƒ } | i ƒ x” | D]Œ } | i | } t | t ƒ o' | i | i d d | | f ƒ ƒ q& | d j o | i d | | f ƒ q& | i d | | | f ƒ q& Wd i | ƒ S( Nt prefixs %s%s.s %s%ss %s%s = %ss ( t linesR R t keyst sortR R R R t appendt __str__R# t Nonet join( R R# R R% R$ R ( ( R R( Û s ' c C s t ƒ } | | i | <| S( N( R R R R R ( R R R ( ( R R ê s c C s@ x9t o1| i ƒ } | p Pn | i ƒ } | p q n | d d j o q n | i d d ƒ } t | ƒ d j o | } d } n! | d i ƒ } | d i ƒ } | i d ƒ } | } xh | d D]\ } y1 | | } t | t ƒ p t d | ƒ ‚ n WqÉ t j o | i | ƒ } qÉ XqÉ W| | | d <q Wd S( Ni t #t =i t .iÿÿÿÿs value-namespace conflict( t Truet fpt readlinet linet stript splitt datat lenR R) R t name_componentsR R t nR R R R R ( R R/ R R6 R7 R R1 R R4 ( ( R t readfpï s6 ( R R R R) R R R R R R R( R R8 ( ( ( R R † s A N( R R R R R ( R R R ( ( R t ?: s 3
