Common Issues Identified

1. FOR Loop Closure Syntax

Issue: Using END instead of ENDFOR for FOR loops with BEGIN blocks Status: ✅ Fixed in 10 files Example:

❌ Wrong:
FOR i=0,n DO BEGIN
    statement
END

✅ Correct:
FOR i=0,n DO BEGIN
    statement
ENDFOR

2. Wildcard Array Assignment

Issue: Parser doesn’t support array[*, *, *] = value syntax Affected: Scientific workflow demos Workaround: Use explicit loops or REFORM

3. FUNCTION Definitions in Scripts

Issue: Parser may not handle inline FUNCTION definitions correctly Affected: data_loading_utils.xdl, fluid_dynamics_demo.xdl Status: Needs parser enhancement

4. Nested FOR/IF Structures

Issue: Complex nesting causes ambiguous END/ENDFOR matching Affected: mandelbrot_demo.xdl, advanced_viz_demo.xdl Status: Requires manual review and fix

5. Visualization Timeouts

Issue: 3D rendering demos take >3s to initialize Status: Expected behavior - not errors

Files Requiring Manual Review

High Priority (Core functionality broken):

  1. examples/scientific/*.xdl - All 6 scientific workflow demos
  2. examples/demo/mandelbrot_demo.xdl
  3. examples/demo/advanced_viz_demo.xdl
  4. examples/demo/comprehensive_control_flow_demo.xdl

Medium Priority (ML/Complex examples):

  1. examples/xdl/ml_comprehensive_test.xdl
  2. examples/xdl/ml_cross_validation_test.xdl
  3. examples/xdl/ml_kmeans_test.xdl
  4. examples/xdl/ml_regularization_test.xdl

Low Priority (Duplicate/legacy tests):

  1. examples/xdl/rayleigh_taylor.xdl (duplicate of demo version)
  2. tests/simple_test.xdl
  3. tests/advanced_control_flow_tests.xdl

Files with Minimal Use / Can Be Removed

Candidates for Removal:

  1. examples/xdl/rayleigh_taylor.xdl - Duplicate of demo/rayleigh_taylor.xdl
  2. examples/xdl/sample_script.xdl - Generic test file
  3. tests/simple_test.xdl - Superseded by specific tests
  4. tests/scientific_python_test.xdl - Superseded by scientific_python_fixed_test.xdl
  5. examples/xdl/test_print.xdl.pro - .pro file, not .xdl

Recommendations

Immediate Actions

  1. ✅ DONE: Fix FOR loop syntax in 10 files
  2. ✅ DONE: Document GDL/IDL syntax rules
  3. TODO: Fix scientific workflow demos (wildcard syntax)
  4. TODO: Fix nested FOR/IF in mandelbrot demos

Parser Enhancements Needed

  1. Support wildcard array assignment: arr[*, *, *] = value
  2. Better handling of inline FUNCTION definitions
  3. Improved nested structure tracking for END/ENDFOR matching
  4. Line continuation with $ in complex expressions

Documentation Updates

  1. Add troubleshooting section to README
  2. Document known limitations
  3. Create migration guide from IDL/GDL

Cleanup Recommendations

  • Remove duplicate rayleigh_taylor.xdl
  • Archive superseded test files
  • Consolidate ML test files
