Remove mrb_ast_head_node structure and cons_head() function while maintaining accurate line number tracking for debugging. Replace cons_head() calls with cons() calls but preserve NODE_VARIABLE wrapper as requested. Key changes: - Remove mrb_ast_head_node struct and head() macro from node.h - Remove cons_head_gen() function and cons_head() macro from parse.y - Update SET_LINENO macro to work with variable-sized nodes: SET_LINENO(c,n) (((struct mrb_ast_var_header*)(c)->cdr)->lineno = (n)) - Restore all 11 SET_LINENO calls in grammar rules to maintain accurate line number reporting for error messages and debugging - Convert list1/list2/list3 and all new_*() function calls to use cons() instead of cons_head() while keeping NODE_VARIABLE wrapper intact 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
