Unified ColdFusion Custom Tag Traversal In CFML Engines

This article details an investigation into traversing ColdFusion custom tag stacks across different CFML engines (Adobe ColdFusion, Boxlang, and Lucee CFML). The author creates a hierarchy of custom tags to test stack lookup behavior, highlighting discrepancies in how each engine handles tags like cfmodule and exposes tag data. The post includes a custom function to normalize differences, addressing bugs and variance in instance counting versus skip levels. This work is part of a larger CFMailML project.
