INI-files parser with schemes and types
Project description
INI-files parser with schemes and types
Philosophy of Zini
Application’s settings must be simple! In it should be a code or complex structures. Must be only a simple types.
Why not…
JSON?
JSON is uncomfortable and unextendable.
YAML?
The YAML is like a garden of rakes. It’s very complex format. I do not need all it’s futures.
Configparser?
Configparser is ugly;
Configparser is overengineered;
Configparser is not have type casting;
Configparser is not have type checking;
Configparser is… configparser.
Supported types
- boolean:
simple true or false, e.g. key = true
- int:
simple numeric type, e.g. key = 13
- float:
float type, e.g. key = 3.14
- string:
strings always uses quotes, e.g. key = "some string"
- datetime:
datetime formated like as ISO 8601
YYYY-MM-DD
YYYY-MM-DD hh:mm
YYYY-MM-DD hh:mm:ss
YYYY-MM-DD hh:mm:ss.sss
When the time, you can set timezone as Z or ±hh:mm.
E.g.:
key = 2005-01-13
key = 2005-01-13 18:00:05
key = 2005-01-13 15:00:05 +03:00
key = 2005-01-13 15:00Z
- timedelta:
durations:
key = 20m — 20 minutes
key = 10h2m — 10 hours and 2 minutes
key = 1w2s — one week (7 days) and 2 seconds
key = 1s20ms — one 2 second and 20 milliseconds
key = 1w1d1h1m1s1ms — 694861001 milliseconds
Examples
$ cat tests/test.ini
# first comment
[first]
boolean = false
integer = 13
[second]
; second comment
boolean = true
string = "some string"Simple reading
>>> from zini import Zini
>>> ini = Zini()
>>> result = ini.read('tests/test.ini')
>>> isinstance(result, dict)
True
>>> result['first']['boolean'] is False # automatic type casting
True
>>> result['first']['integer'] == 13
True
>>> result['second']['string'] == "some string"
TrueTypes and defaults
>>> from zini import Zini
>>> ini = Zini()
>>> ini['first']['integer'] = str # set type
>>> result = ini.read('tests/test.ini')
zini.ParseError: error in line 3: 'integer = 13'>>> from zini import Zini
>>> ini = Zini()
>>> ini['second']['boolean'] = "string" # set type and default value
>>> result = ini.read('tests/test.ini')
zini.ParseError: error in line 7: 'boolean = true'
