Run Performance Benchmarks

Compile and run benchmarks for this project's parser, analyzer, and fix functions.

Steps

1. Compile TypeScript:

   npx tsc -p . --outDir out
   

2. Run benchmarks based on arguments:

   • functions — individual function benchmarks only:

     npx mocha --ui tdd --require out/test/vscode-mock.js --timeout 30000 "out/test/benchmark/functions.bench.js"
     

   • pipeline — full analysis pipeline benchmarks only:

     npx mocha --ui tdd --require out/test/vscode-mock.js --timeout 30000 "out/test/benchmark/pipeline.bench.js"
     

   • No arguments — run all benchmarks:

     npm run test:bench
     

3. Analyze the results table and report:

   • Any individual function with avg > 0.01ms (potential bottleneck)
   • Pipeline throughput: if 500-line file analysis exceeds 5ms, flag as performance concern
   • Compare relative performance across functions to identify outliers

Benchmark files

File	What it measures
src/test/benchmark/functions.bench.ts	Individual function execution time (tokenize, parseArgs, parseRange, fix functions, etc.)
src/test/benchmark/pipeline.bench.ts	End-to-end file analysis (10/100/500 lines) with tokenization + selector finding + score tracking + fixes
src/test/fixtures/mcfunction.ts	Test fixtures: SHORT (10 lines), MEDIUM (100 lines), LARGE (500 lines)
