escriba-ts 0.1.71

//! `escriba-ts` — tree-sitter host for escriba.
//!
//! The tree-sitter host now lives in **`hikari-ts`** (the fleet syntax spine's
//! tree-sitter backend, self-contained on crates.io). This crate re-exports it
//! so escriba's consumers keep a stable `escriba_ts::…` surface while the host
//! itself has exactly one home — the dedup + load-bearing-fix that also breaks
//! the old `hikari-ts → escriba-ts` dependency inversion (a fleet library must
//! not depend on an application crate).
//!
//! `escriba_ts::Semantic` is `hikari_token::Semantic` (the deduped fleet
//! vocabulary), carrying the total `From<Semantic> for hikari_core::HlClass`.

/// Escriba-local language plugins — the languages the fleet spine does not

/// **Tree-sitter grammars take precedence** for the languages they cover; the
/// zero-dep table backend fills every other language; escriba-local tables
/// register LAST, so an upstream hikari backend for the same language always
/// wins and a local table retires itself with no edit here.
///
/// It lived in `escriba-render::gpu` until 2026-08-08, which put escriba's
/// language knowledge behind a GPU dependency: the runtime could not ask what
/// a symbol is without taking on wgpu, and the ratatui face — which needs no
/// GPU at all — has no syntax highlighting to this day. Registry construction
/// is not rendering.
