confini 0.3.4

Parse, verify and merge all ini files in a single directory

CONFINI

Configuration parser that process all sections and values in all ini files in a directory.

Usage

import confini

c = confini.Config('/path/to/config/dir')
c.process()

print(c.get('FOO_BAR_BAZ'))

Value storage

The values are stored in a single key/value dictionary, with section and name separated by underscore and all letters transformed to uppercase.

Consider this value in an ini section:

[foO]
bar_baz = 42

This will be stored in the confini store with FOO_BAR_BAZ as the key.

Environment overrides

By default, the value of any environment variable matching a store key will overwrite the corresponding value in the store.

A prefix can be provided on instantiation to define a separate namespace for environment variable overrides:

>>> os.environ.set('FOO_BAZ_BAZ', 666)
>>> c = config.Config('/path/to/config/dir')
>>> c.process()
>>> print(c.get('FOO_BAR_BAZ'))
666
>>> c = config.Config('/path/to/config/dir', 'XXX')
>>> c.process()
>>> print(c.get('FOO_BAR_BAZ'))
42
>>> os.environ.set('XXX_FOO_BAZ_BAZ', 13)
>>> c = config.Config('/path/to/config/dir', 'XXX')
>>> c.process()
>>> print(c.get('FOO_BAR_BAZ'))
13

Required values

Keys can be set as required, and after processing independently validated:

>>> c = config.Config('/path/to/config/dir')
>>> c.require('BAR_BAZ', 'FOO')
>>> c.process()
>>> c.validate()
True
>>> c = config.Config('/path/to/config/dir')
>>> c.require('BAR_BAZ_BAZ', 'FOO')
>>> c.process()
>>> c.validate()
False

Censoring logs

The string representation of the confini object is a list of all stored values, one on each line.

Display of individual values can be suppressed:

>>> c = config.Config('/path/to/config/dir')
>>> c.process()
>>> print(c)
FOO_BAR_BAZ = 666
>>> c.censor('BAR_BAZ', 'FOO')
>>> print(c)
***

Encryption

Values can be GNUPG encrypted by saving them in individual encrypted files providing the filename as value argument wrapped in a gpg directve:

[foo]
BAR_BAZ = !gpg(foo_bar_baz.asc)

Decryption mode is on by default, and can be deactivated on instantiation:

>>> c = config.Config('/path/to/config/dir')
>>> c.process()
>>> c.get()
666
>>> c = config.Config('/path/to/config/dir', decrypt=False)
>>> c.process()
>>> c.get()
!gpg(foo_bar_baz.asc)

The user keyring in the default location is used for decryption, which may be overridden as usual with the GNUPGHOME environment variable.
