v0.5.4

Fixes npm packaging so the platform binaries are actually included in the @reteps/dockerfmt-* tarballs (0.5.3 shipped them empty, breaking the npx launcher). Also upgrades the JS toolchain (TypeScript 6, @types/node 24) and makes the publish workflow reproducible and idempotent.

v0.5.2

What's new

• # dockerfmt-ignore directive — place this comment before any directive to skip formatting for it. Useful as an escape hatch for command grouping, unescaped semicolons, or intentional formatting.
• EditorConfig support — indent_size, insert_final_newline, and custom space_redirects are read from .editorconfig files. CLI flags take precedence.

See the README for usage details.

v0.5.1

Fix: Go WASM global constructor conflict

Problem: Importing @reteps/dockerfmt overwrote globalThis.Go, breaking other Go WASM packages (e.g. sh-syntax) that rely on their own wasm_exec.js with different capabilities like WASI support.

Fix: The Go class is now scoped under globalThis.__dockerfmt_Go instead of clobbering globalThis.Go. Any previously set Go constructor is preserved.

v0.5.0

What's Changed

Fix JS/WASM bindings (#25)

The JS bindings (@reteps/dockerfmt) have been broken since the initial release due to TinyGo bugs:

• reflect.AssignableTo panics with interfaces, breaking encoding/json used by the buildkit parser (tinygo#4277)
• \s regexp failures in newer TinyGo versions, also breaking the buildkit parser

This release switches from TinyGo to standard Go (GOOS=js GOARCH=wasm), which has full reflect and regexp support. The WASM binary is larger (2 MB → 6.9 MB) but the bindings now work correctly for all Dockerfile forms — both shell-form (CMD echo hello) and JSON-form (CMD ["echo", "hello"]).

Other changes

• Added CI workflow (Go tests + JS build/test) on PRs and main pushes
• Added JS integration tests
• Replaced encoding/json with reflection-free []string JSON marshal/unmarshal
• Simplified JS bindings by using syscall/js instead of manual memory management
• Switched npm publish to OIDC trusted publishing

v0.4.0

What's Changed

• Refactored formatting engine — Cleaned up core formatting with better structure and comprehensive unit tests
• Fixed multiline flag duplication — RUN instruction flags (e.g. --mount) are no longer duplicated when formatting line breaks (#42)
• Version tagging — Docker images and Go binaries are now tagged with the release version (#47)
• Version set via ldflags — Version is now set at build time instead of being hardcoded
• Improved CLI help — Documents stdin input processing in the command help message (#43)
