Why pure Go

go-ruby-bbolt/bbolt reimplements Ruby's bbolt in pure Go, with cgo disabled. The slice of Ruby it covers is deterministic and interpreter-independent: given its inputs, the result is a pure function of those inputs — no live binding, no evaluation of arbitrary Ruby. That is exactly the part that can — and should — live as a standalone Go library, separate from the interpreter.

Extracted for reuse, reusable by anyone

  • any Go program can import github.com/go-ruby-bbolt/bbolt directly, with no Ruby runtime;
  • the dependency runs the other way — rbgo binds this module as a native module for go-embedded-ruby (the same pattern as go-ruby-yaml), rather than this module depending on the interpreter;
  • the behaviour is pinned by a differential oracle against reference Ruby, independent of any one consumer.

Why pure Go matters here

Because the library is CGO-free, it:

  • cross-compiles to every Go target with no C toolchain, and links into a single static binary;
  • has no dependency on the Ruby runtime — the dependency runs the other way;
  • can be differentially tested against the ruby binary wherever one is on PATH, while the cross-arch lanes still validate the library itself.
