Hobbes is a strongly typed domain-specific language with an embedded JIT compiler and runtime for efficient dynamic expression evaluation, data storage, and analysis, designed for high-performance integration with C/C++ applications. It supports pattern matching, comprehensions, LALR(1) parsing, type classes, and remote native code compilation over trusted networks.

Use cases

• embed a JIT-compiled scripting language in a C++ application
• evaluate dynamic expressions at runtime with low overhead
• record structured data for out-of-band analysis
• parse text with LALR(1) grammars
• classify and destructure data with efficient pattern matching
• run remote code compilation between internal services

When to choose

• you need a fast embedded DSL inside C/C++ systems
• you want dynamic expression evaluation without sacrificing native performance
• you need efficient data recording and analysis in low-latency environments

When to avoid

• you need a sandboxed or memory-safe scripting environment
• you target platforms other than Linux
• you cannot trust the code being compiled and executed remotely
