Replaced multiple string-manipulating regular expressions (lookarounds for camel case, format validation, whitespace normalization) with a single manual character iteration loop and a StringBuilder. This avoids significant compilation and backtracking overhead from the Regex state machine in this hot path. Co-authored-by: himattm <6266621+himattm@users.noreply.github.com>

Closing this in favor of #74, which curates the parser hot-path changes without the generated |
Understood. Acknowledging that this work is now obsolete and stopping work on this task. |
💡 What: Replaced multiple string-manipulating regular expressions in
HintExtractor.ktwith a single manual character iteration loop and aStringBuilder.🎯 Why: In Kotlin hot paths, relying on multiple regular expressions (e.g., lookarounds for camel case, format validation, whitespace normalization) introduces significant overhead due to state machine compilation and backtracking.
📊 Impact: Reduces CPU cycles and memory allocations significantly during hint extraction by avoiding multiple regex state machine compilations and backtracking overhead, leading to faster execution times.
🔬 Measurement: Run
./gradlew :halogen-engine:testto verify that the extraction logic remains perfectly correct. Profile the execution ofHintExtractor.extractto observe the reduced allocation rate and CPU time.PR created automatically by Jules for task 14945420773654845847 started by @himattm
