Compiler Configuration and Transform Rules

AXSG merges configuration from multiple sources before the binder/emitter pipeline runs.

Configuration sources

The compiler host can read configuration from:

  • MSBuild items and properties
  • file-based configuration documents
  • transform-rule documents
  • framework/profile defaults

Precedence

Configuration is not merged arbitrarily. AXSG applies explicit precedence rules so the final effective configuration is deterministic.

This matters for:

  • global XML namespace mappings
  • string-to-type alias tables
  • transform rules
  • backend and profile behavior

Transform rules

Transform-rule documents let the host converge project-specific conventions into compiler decisions without hardcoding those rules into the stable compiler core.

This is the main extension point for:

  • namespace remapping
  • type aliasing
  • feature-shape convergence across projects
  • migration layers from other markup/codegen conventions
