Tya v0.61 Release Notes

v0.61 is the current released implementation. It includes stackable interface behavior, native packages, package tools, new class-style standard-library packages, WASM build targets, and the first external package ecosystem split into separate repositories.

Language

• Interfaces may define default instance methods.
• Interface defaults can satisfy body-free requirements from other interfaces.
• Interfaces may contribute instance fields.
• Interfaces may define zero-argument initialize hooks.
• Interface initializer hooks run at a class constructor’s super() point.
• Class overrides can call super() into the interface default stack.
• Interface default methods can call super() through stacked defaults.
• Same-name interface fields and unrelated default methods require explicit class resolution.
• String interpolation now balances nested braces and preserves quotes inside interpolation expressions, so forms such as {user["name"]} and dictionary literals inside interpolation compile correctly.

Toolchain and Packages

• tya.toml supports an optional [native] table with C sources, headers, include directories, pkg-config dependencies, cflags, ldflags, and declared native functions.
• tya build, tya run, and tya test use the same native metadata collection path.
• Native wrappers are called through the existing TyaValue runtime ABI.
• Missing native files, missing pkg-config, missing host dependencies, and duplicate native function names produce clear diagnostics.
• tya new --template lib --native <name> creates a buildable native package scaffold.
• tya doctor native reports the current native build environment and effective flags.
• New package tool declarations let packages expose Tya script commands through [tools], and tya tool runs locked dependency tools or pinned one-shot git/path tools.
• WebAssembly build targets were added, with unsupported native package usage rejected for WASM builds.

Standard Library

• net/http.Server now supports route groups, middleware, custom 404/500 handlers, named paths, redirects, PATCH/HEAD/OPTIONS/ANY routing, wildcard tail captures, and optional trailing-slash matching.
• New cli.Cli helpers parse command-line options, positional arguments, defaults, required options, --, and deterministic usage text.
• New template.Template renderer handles generic text templates with variables, dotted/indexed paths, conditionals, loops, explicit partials, file rendering, strict missing-value errors, and optional HTML escaping.
• markdown.Markdown now has class-style parse, to_html_ast, and render APIs, plus tables, task lists, strikethrough, fenced-code info strings, reference links, images, nested lists, setext headings, and opt-in raw HTML.
• New compress.Compress helpers gzip/gunzip and zlib/unzlib strings, bytes, and files.
• New log.Logger writes level-filtered text or JSON records to stderr by default or appends them to a configured file path.
• New io.Io streams wrap stdin/stdout/stderr and file readers/writers with line iteration, chunk reads, binary modes, and stream copying.
• New net/ip package parses and classifies IPv4, IPv6, IPv4-mapped IPv6, and CIDR networks.
• New net/socket package exposes TCP client/server sockets with text and binary reads, line helpers, address inspection, timeouts, and structured connection failures.
• url.Url now parses bracketed IPv6 hosts, validates percent escapes and ports, resolves relative references, normalizes paths, and preserves duplicate query keys.
• New color.Color values provide RGBA channels, hex/CSS parsing, named colors, conversion helpers, and deterministic color operations.
• New geometry values provide Vector2, Vector3, Point, Size, Rect, and Circle helpers for reusable spatial calculations.
• New transform2d.Transform2D values provide 2D affine transforms, geometry application helpers, inversion, composition, and matrix interop.
• New compiler/* introspection packages expose lexer, parser, AST, checker, and formatter results as stable public Tya dictionaries.
• New binary.Reader and binary.Writer values provide endian-aware integer and IEEE 754 float reads/writes over bytes.
• New collections values provide Stack, Queue, Deque, Set, and stable min-priority queue containers.
• random now includes independent Rng instances plus bool, shuffle_copy, sample, weighted_choice, and weighted_index helpers.
• New serialization.Serializer helpers convert primitives, dictionaries, bytes, and class instances to JSON-compatible data, JSON, and TOML.
• New xml DOM classes parse, inspect, and dump practical XML, including common JUnit XML output.
• New image.Image and image.Codec classes provide deterministic RGBA image metadata, pixel access, transforms, and byte/file round trips.

External Packages and Tools

The following projects are released as separate repositories and are not part of Tya’s standard library:

• https://github.com/komagata/tya-sqlite
• https://github.com/komagata/tya-sdl2
• https://github.com/komagata/tya-gtk4
• https://github.com/komagata/tya-raylib
• https://github.com/komagata/tya-slim
• https://github.com/komagata/flakewatch
• https://github.com/komagata/magvideo

Each package/tool is distributed by git URL plus tag. Tya still has no central package registry and no tya publish command.

Verification

The release gate is:

go test ./... -count=1

The published v0.61.0 tag passed the full suite, including the maintained self-host fixed-point tests.
