Source test case valid for testing period character in macros.

The test case correctly defines a macro fragCoord on line 1 and uses it with property access (.xy) on lines 3-4, which tests the scenario described in the PR objective. This provides a good test case for verifying that macros containing period characters are properly expanded.

However, I notice that the actual implementation change to isPpCharacters (removing period from recognized characters) isn't included in the files for review. This is an important part of the fix.

🏁 Script executed:

#!/bin/bash
# Let's find and verify the changes to isPpCharacters function
rg -p "isPpCharacters" --type ts packages/

Attention: Missing Implementation Update in isPpCharacters

The test file at tests/src/shader-lab/test-case/source/macro.txt successfully verifies macro expansion with period characters. However, after running the verification script, it appears that while the function isPpCharacters is present in both packages/shader-lab/src/preprocessor/PpScanner.ts and packages/shader-lab/src/lexer/Utils.ts, its implementation has not been updated to remove the period ('.') from the recognized characters. This part of the fix, which is critical for the PR objective, is currently missing.

  • Test Case:

    • File: tests/src/shader-lab/test-case/source/macro.txt
    • Status: Test case correctly validates macro expansion using a period.

  • Issue:

    • File: packages/shader-lab/src/lexer/Utils.ts
    • Concern: The implementation of isPpCharacters does not reflect the change to exclude the period character.

Please update isPpCharacters to remove the period from the set of recognized characters as described in the PR objective.
