- Skip no-op splats of empty array literals (`*[]` / zarray) in call argument generation and array literal codegen. - Inline non-empty literal splat arrays without inner splats (e.g. `*[a,b]`) as regular positional args/elements, avoiding building a temporary array and ARYCAT. This removes unnecessary `LOADNIL` + `ARRAY 0` + `ARYCAT` sequences (e.g. `mruby -ve 'p *[]'`) and reduces temporary allocations while preserving semantics and evaluation order. Falls back to the generic path when nested splats are present or counts exceed fixed-arity. No behavior change intended; only codegen improvements. Co-authored-by: Codex <codex@openai.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
