Language Tool Benchmark

Benchmarks for various language engineering tools, comparing the same statemachine DSL implemented in Langium (TypeScript), Fastbelt (Go), Xtext (Java), and AnyText (C#).

Requirements

• Node.js 22+ and npm
• Go, version per fastbelt/statemachine/go.mod
• .NET SDK 9+ and the anytextgen CLI (installed via dotnet tool install --global NMF-AnyTextGen)
• JDK 21+ and Maven
• dotnet-trace (dotnet tool install --global dotnet-trace), for bench:anytext:alloc only

Run npm install once before anything else.

Benchmark

The package.json contains multiple scripts to execute different benchmarks. Run npm run bench:sweep to run them all. This will take 10-15 minutes.
