Hello,
I need your help to recommend some projects that I can use in my study of
transforming deprecations.
As many of you know, Pharo supports a very powerful concept of
"transforming" deprecations. You can deprecate a method, providing a
transformation rule. Then when a client application calls the deprecated
method, the call-site will be automatically rewritten to use the new API.
Here is an example of a transforming deprecation:
Collection >> includesAllOf: values
self
deprecated: ‘Use #includesAll: instead’
transformWith: ‘`@rec includesAllOf: `@arg’ ->
‘`@rec includesAll: `@arg’.
^ self includesAll: values
You can read more about transforming deprecations in my blog post:

I am working on a tool that can analyse the commit history of a project and
recommend deprecations and transformation rules that can be inserted before
the release. It works like this:
1. Collect all commits between two releases of a project
2. Mine those commits to identify method call replacements (deletions and
additions) that happen frequently
3. Infer the mapping between the methods of the old and new API
4. Recommend deprecations and generate transformation rules
I have validated my approach on Pharo, Moose, Pillar, Famix, and DataFrame
projects.
Now I am looking for other projects that could benefit from recommended
deprecations and could be used in my study.
*Required:*
- open source project with accessible commit history (e.g. public git
repository)
- written in Pharo (although if you know projects in other languages that
could be interesting for my study, please let me know about them as well)
*Prefered:*
- ongoing development
- multiple releases
- has users (other projects that depend on it)
If you have some projects in mind, please let me know about them!
And if you are interested in this study and want to learn more, don't
hesitate to contact me by email.
