Trax‎ > ‎

Video Demo

This video is a demonstration of Trax, a git inspired object versioning system for squeak. Any object that can be serialized can be stored and versioned in Trax and the lineage of those objects can be browsed in the version history browser. Additionally, I plugged Monticello packages into Trax such that Smalltalk source code can be versioned. I modified the package browser to make it possible to commit packages directly from it and I created an n-way merge tool. Below are some notable points where various topics are discussed. Sorry for the watermark and disorganization...this video was a first cut that was originally intended to just be used in creating a script for a final, more polished presentation. Due to a lack of time and the need to work on another project, I've decided to just publish this raw video in the hopes it might inspire others to pickup the code, reuse it in other projects, or just get a few ideas.
