CleanerML Repository
CleanerML
CleanerML is a simple yet powerful markup language for writing cleaners. Most of BleachBit’s cleaners are written in CleanerML, and you can write your own cleaners in CleanerML, too.
You can think of it as writing XML to delete files, but it is more powerful than that.
BleachBit
BleachBit is an open source system cleaner for Windows and Linux.
How to contribute
There are three ways to contribute: review a pull request, review cleaners that
are already submitted, or write your own cleaner.
For any of these, start here:
- Download BleachBit.
- Read Documentation on CleanerML.
- Read Contributing a cleaner.
After making changes to a cleaner, run make tests to check for errors because the
XSD can find many errors in the XML. It’s best to also run make pretty before
commiting a change.
How to use
In the future automated sync may be as easy as checking one option, but for now you must manually
download and copy the files to your personal cleaners directory. The easiest way to find the
directory is to open BleachBit, click the hamburger menu (three horizontal lines), click Diagnostics,
and look for the line with personal_cleaner_dir.
Contents
The directory pending contains cleaners that are waiting for someone to verify they are safe and effective.
The directory release contains cleaners that are considered safe and effective.
