Kotlin Mania - Porting the future

JWT creation, decoding and verification using an auth0-compatible API; HMAC algorithms (HS256/384/512) plus unsecured "none", common-code-first design, source or JitPack consumption.

Parses CSI/SGR ANSI escape sequences into styled text slices with color, intensity and style metadata; reconstructs plain text, iterates lines, and supports all 16 ANSI colors.

Per-object thread-local storage: ThreadLocal type supplies independent per-thread object copies; faithful line-by-line transliteration of upstream crate, port-lint provenance headers, feature-parity in-progress.

Pure systems-programming toolkit enabling bit-exact C semantics with single-heap memory, C-compatible types, deterministic floating-point, and dual-mode bitshift engine for reliable C-to-language porting.

Parses ANSI escape sequences into ratatui-styled text, converting terminal color/style codes (4-, 8-, 24-bit colors; bold, italic, underline, reset) for TUI rendering.

Terminal styling toolkit: style definitions, git/LS_COLORS parsers, ANSI escape parsing, converters to ROFF/SVG, backend adapters and color utilities for colored terminal output.

Cook up interactive terminal user interfaces using a flexible widget-based toolkit with layout system, ready-made templates, extensive examples, documentation, and community resources for building text-based apps.

Cassowary constraint-solving implementation for UI layout, low-level solver API with weighted strengths, editable variables for interactive updates, and dual error styles (exceptions or Result-based).

Generate ROFF man pages programmatically using an abstract document model, inline styles, control directives, text-formatting helpers, and safe rendering with apostrophe handling.

Terminal manipulation toolkit: cursor control, rich color/styling (16/256/RGB) and attributes, screen/raw-mode management, event polling (keyboard, mouse, resize), command-pattern ANSI batching.

Ordered B-tree map and set implementing Rust std semantics, preserving upstream behavior and tests; offers stable-order iteration, efficient B-tree operations, and parity-oriented translation.

LR(1) parser generator implementing the lalrpop grammar and architecture, offering a configuration API to process .lalrpop grammars, Cargo-style conventions and code generation.

Line-by-line transliteration of a Rust source-code parser: complete syntax tree representation, token parsing/printing, span-aware error reporting, derive parsing helpers and traversal/transformation APIs.

Quasi-quoting toolkit enabling code-as-data generation of token streams via quote-like macro syntax: interpolation, repetition, identifier construction, span-aware hygiene, and composable token fragments for code generation.

Wrapper around compiler's procedural-macro API, enabling proc-macro-like token streams outside macros, making macro logic unit-testable; faithful line-by-line transliteration preserving upstream behavior and provenance.

Ergonomic trait-object error type for idiomatic application error handling; attach contextual messages, downcast to concrete error types, capture backtraces, and create errors with concise macros.

Immutable, cheaply-cloneable byte containers and cursored read/write views; typed big- and little-endian numeric access, chaining/limiting adapters, iterator/reader/writer adapters, Result-based safe reads.

Collection of well-tested utility extensions and types: ergonomic collection/string helpers (Vec.map, split1), a cheap-copy Dupe trait, and ARef abstraction for uniform references.

Line-by-line transliteration of a mature parser-generator, enabling compact readable grammars, reusable grammar macros, operator and type-inference support, compact defaults, and LR(1)/LALR(1) parsing.

Line-by-line transliteration of an upstream map implementation, delivering faithful feature-parity collections with port-lint headers for provenance tracking and translator guidelines enforcing disciplined ports.
