v1.4.0

GoAlign v1.4.0

Highlights

• Cacheguard — detect false sharing; --cacheguard / --cache-line pad isolation
• Config — .goalign.yml project defaults
• --packages — resolve imported type sizes via go/packages
• SARIF — GitHub Code Scanning output (-f sarif)
• Policies — --policy=atomics|density|stable
• Fix UX — --diff / --dry-run; opt-in --rewrite-bools
• Multi-arch — --arches summary matrix
• Vet plugin — goalign-analyzer

Hardening

• Correct atomic.Value / Uintptr / Pointer / unsafe.Pointer sizes
• Field-ignore full-struct metrics; safer fixer (atomic writes, slot mapping, comments)
• Config arches rejected on fix; machine formats under --arches; min-waste keeps false-share/cacheguard

See CHANGELOG.md for the full list.

Install

go install github.com/gopherust-io/goalign@v1.4.0

v1.3.0 — Parallelism and architecture docs

Highlights

• --jobs / -j to control parallel file analyzes (default: min(GOMAXPROCS, 8))
• goalign fix reuses analyze source bytes via FixContent (avoids a second disk read)
• Faster // goalign:ignore handling with a per-file line index
• New ARCHITECTURE.md documenting CLI layers and packages

Install

go install github.com/gopherust-io/goalign@v1.3.0

Notes

• Colorized TTY text output; JSON and table formats retained
• Module path moved to github.com/gopherust-io/goalign; Go 1.26.5
• OpenSSF Scorecard pack, security policy, and Apache License 2.0
• Hardened gRPC/protobuf decode paths and CodeQL integer-conversion fixes
• Broader test coverage and shared alignmath / goarch helpers

Install

go install github.com/gopherust-io/goalign@v1.2.0

Notes

• Prefer this release or newer for production installs under the gopherust-io org.

v1.1.0 — Layout engine and CI flags

Highlights

• Zero-alloc layout math with reused buffers (Compute / suggest path)
• NATS-style packing guidance (atomics-first, density packing notes)
• CI-friendly analyze flags: --fail-on-findings, --min-waste, --arch
• Improved layout correctness for multi-arch targets

Install

go install github.com/gopherust-io/goalign@v1.1.0

Notes

• Suited for gating PRs in CI with a non-zero exit on findings.

v1.0.0 — Initial release

Highlights

• Struct alignment analysis for Go sources (padding waste and field layout)
• Output formats: text, JSON, and table
• Support for // goalign:ignore on types
• Recursive directory scanning with severity levels

Install

go install github.com/gopherust-io/goalign@v1.0.0

Notes

• First public CLI release.
