Consolidated NODE_WHILE, NODE_UNTIL, NODE_WHILE_MOD, and NODE_UNTIL_MOD dump cases using a shared dump_loop_node label. All four loop constructs have identical structure (condition + body) and only differ in their node type names. Uses fall-through for the last case (NODE_UNTIL_MOD) to avoid unnecessary goto. This eliminates code duplication (28 lines -> 12 lines) while maintaining the same clear output format for each loop type. Co-authored-by: Claude <noreply@anthropic.com>
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.
mrbcexecutable: A command-line tool for compiling.rbfiles into.mrbbytecode 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
