ini-parser 2.0.1

An ini parser/serializer in Python

ini-parser

An ini format parser and serializer for Python.

Sections are treated as nested dictionaries. Items before the first heading are saved on the object directly.

Usage

Consider an ini-file config.ini that looks like this:

; this comment is being ignored
scope = global

[database]
user = dbuser
password = dbpassword
database = use_this_database

[paths.default]
datadir = /var/lib/data
array[] = first value
array[] = second value
array[] = third value

You can read, manipulate and write the ini-file like so:

import ini

config = ini.parse(open('config.ini').read(), preserve_comments=True)

config['scope'] = 'local'
config['database']['database'] = 'use_another_database'
config['paths']['default']['tmpdir'] = '/tmp'
del config['paths']['default']['datadir']
config['paths']['default']['array'].append('fourth value')

with open('config_modified.ini', 'w+') as f:
    f.write(ini.stringify(config, section='section'))

This will result in a file called config_modified.ini being written to the filesystem with the following content:

[section]
scope = local

[section.database]
user = dbuser
password = dbpassword
database = use_another_database

[section.paths.default]
array[] = first value
array[] = second value
array[] = third value
array[] = fourth value
tmpdir = /tmp

API

decode(inistring, on_empty_key=None, preserve_comments=True)

Decode the ini-style formatted inistring into a nested object.

• on_empty_key: Value to use when a key with no value is encountered during parsing. If set, any key in the INI file that lacks a value will be assigned this value.
• preserve_comments: Boolean to specify whether to preserve comments when parsing. If set to True, comments will be included in the output and parsed from the input. Default is False.

parse(inistring, on_empty_key=None, preserve_comments=True)

Alias for decode(inistring)

encode(object, section=None, whitespace=True)

Encode the object object into an ini-style formatted string. If the optional parameter section is given, then all top-level properties of the object are put into this section and the section-string is prepended to all sub-sections, see the usage example above.

The options object may contain the following:

• section - A string which will be the first section in the encoded ini data. Defaults to none.
• whitespace - Boolean to specify whether to put whitespace around the = character. By default, whitespace is omitted, to be friendly to some older parsers. If set to True, whitespace will be added for readability.

stringify(object, section=None, whitespace=True)

Alias for encode(object, [options])

safe(val)

Escapes the string val such that it is safe to be used as a key or value in an ini-file. Basically escapes quotes. For example

ini.safe('"unsafe string"')

would result in

"\"unsafe string\""

unsafe(val)

Unescapes the string val
