Yukihiro "Matz" Matsumoto 488aa8630b mruby-compiler: handle __except with CALL_MAXARGS fallback
When a hash pattern has 15 or more keys, pack them into an array
before calling __except via OP_SEND with CALL_MAXARGS, since the
OP_SEND instruction can only encode up to 14 direct arguments.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

  • Parser: Translates Ruby source code into an abstract syntax tree (AST).
  • Code Generator: Traverses the AST to produce executable mruby bytecode.
  • mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
