Change Logs

If a package is around long enough and is sufficiently configurable, it will almost undergo a refactoring of the configuration file.

To cope with this inicheck allows developers to add a changelog.ini to warn users and remap old config files if need be.

If a changelog is provided, then the inicheck will stop a program if there is a any matches in the changelog that are in the users configuration file.


If your configuration file contains deprecated information as determined by the changelog, then inicheck will exit the program and report the possible issues.

To use inicheck’s CLI to apply the changes simply use

inicheck -f my_config.ini -m my_module --changes -w

This says apply the changes and output the result.

Writing your own change log


Every changelog must have two sections, a meta section and a changes section. The meta section should have an info item with a description of what happened and why. And it should have a date in which indicates the date at which this went into effect.

Future Feature - Currently inicheck will only handle a single changelog but in the future will use the dates to map the changes to each changelog.

A changelog can track the following type of changes:

  1. Removal of a section or item.
  2. The rename of a section or item.
  3. The migrating of an item to another section
  4. Default changes.

An entry in the change log is done with the following format:


If declaring a default has changed then the syntax is the same plus the property and value appended.


WARNING: If an old default value is identified, auto changing will update any older default values to the new ones.

Look at the following example change log to see various implementations.

Where do I keep my change log

Change logs can only be associated to a module. Its association is done by creating a module attribute called __config_changelog__.

Example in your <my_module>/

import os
__config_changelog__ = os.path.abspath(os.path.dirname(__file__) + '/path/to/changelog.ini')
