Yukihiro "Matz" Matsumoto dc0a5f433f mruby-compiler: optimize NODE_STMTS nesting to reduce AST depth
Modify new_stmts to flatten unnecessary nesting by returning existing
NODE_STMTS directly instead of wrapping them. This reduces memory usage
and AST complexity when multiple parentheses levels are used.

Before: (((expr1; expr2))) creates nested NODE_STMTS
After: (((expr1; expr2))) creates single NODE_STMTS with statements

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
