go-ruby-chronic — a pure-Go reimplementation of Ruby's chronic, MRI-faithful, no cgo

Pure-Go (CGO=0) MRI-faithful Ruby chronic. It is a pure-Go (no cgo) reimplementation of Ruby's chronic, mirroring its observable behaviour without any Ruby runtime. It is a standalone, reusable module — the backend bound into go-embedded-ruby by rbgo, the same pattern as go-ruby-yaml — differential-tested against reference Ruby, 100% coverage, CI green across 8 arches (six 64-bit, plus 32-bit 386 and arm) and 3 OSes.

Pure Go, zero cgo ready

chronic builds with CGO_ENABLED=0 — it cross-compiles to every Go target with no C toolchain and links into a single static binary.

Reference-faithful ready

Mirrors the observable behaviour of Ruby’s chronic from reference Ruby (MRI), validated by a differential oracle against the reference rather than approximated — without any Ruby runtime.

Standalone & reusable ready

A standalone Go module any program can import; the OAuth-style dependency runs the other way — rbgo binds it into go-embedded-ruby as a native module, the same pattern as go-ruby-yaml.

100% coverage · 8 arches ready

100% test coverage is the CI gate, gofmt + go vet clean, green across the six 64-bit Go targets (amd64, arm64, riscv64, loong64, ppc64le, s390x — including the big-endian lane) and on 32-bit 386 and arm since v0.1.0.

ready capability complete (exit criteria met, nothing material left)

A faithful pure-Go port of Ruby's chronic, cgo disabled, so it cross-compiles and embeds anywhere. Validated differentially against reference Ruby. It is a standalone, reusable module and the backend bound by rbgo into the sibling org github.com/go-embedded-ruby.
