- yapf_encode() / yapf_free_buffer(): encode to memory; yapf_save uses it - yapf.c also compiles as C++ - `yapf compare`: size and decode speed of the original format vs YAPF, with a lossless check - bindings with tested examples: C++ (header-only), C# (P/Invoke), Rust (crate, builds the C code), Go (cgo), Java (FFM API, Java 22+), Zig (@cImport), LuaJIT (FFI), TypeScript types for the JS port; Python now encodes in memory - docs/LANGUAGES.md and examples/ with measured results - KDE Dolphin thumbnail plugin (KF6, CMake) - README: honest status for Photoshop / VS Code / Figma (not run in the apps yet) and macOS (cross-compiled only), platform table Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
