Ruby's Marshal in pure Go — byte-exact dump/load, no cgo.
go-ruby-marshal is a pure-Go (no cgo) implementation of Ruby's
Marshal binary serialization — the format Marshal.dump and
Marshal.load use to round-trip Ruby objects. It speaks Marshal
wire format v4.8 and is byte-for-byte identical to MRI Ruby 4.0.5:
it reproduces the Fixnum/Bignum split, MRI's shortest-float formatting, the symbol table and the
object-link table, so shared objects and cycles serialize and round-trip exactly
as the reference interpreter does. It is standalone and reusable over its own typed value model
(Nil / Bool / Int / Float / Symbol /
Str / Array / Hash), and is the serialization member of the
go-ruby-* family that go-embedded-ruby builds on — 100% coverage, CI green across 6 arches.
The library: Marshal.dump / Marshal.load for Ruby’s binary serialization (wire format v4.8) over a typed value model — Nil / Bool / Int / Float / Symbol / Str / Array / Hash. Byte-for-byte identical to MRI: the Fixnum/Bignum split, MRI’s shortest-float formatting, the symbol table, and the object-link table so shared objects and cycles round-trip.
A pure-Go, cgo-disabled implementation, so it cross-compiles and embeds anywhere. It reads and writes Marshal v4.8 byte-for-byte against MRI — the integer encoding, shortest-float formatting, symbol table and object-link table that make shared objects and cycles round-trip — over a small typed value model. It is a standalone, reusable module and the serialization member of the sibling family go-ruby-parser · go-ruby-regexp, consumed by github.com/go-embedded-ruby.
