escriba_core/lib.rs
1//! `escriba-core` — foundational types.
2//!
3//! No I/O. No rendering. No tatara-lisp. Just the typed vocabulary every
4//! other escriba crate speaks:
5//!
6//! - [`Position`] — line + column, 0-indexed, UTF-8 char offsets.
7//! - [`Range`] — half-open `[start, end)`.
8//! - [`Cursor`] — anchor + head (for selection growth).
9//! - [`Selection`] — multi-cursor ordered set.
10//! - [`Mode`] — the vim-ish modal state.
11//! - [`Motion`] / [`Operator`] — compose into commands.
12//! - [`Edit`] — primitive mutation.
13//! - [`Action`] — top-level dispatched-to-buffer command.
14//! - [`BufferId`] / [`WindowId`] — opaque identifiers.
15//!
16//! Every type derives `schemars::JsonSchema` so escriba-api can emit an
17//! OpenAPI spec over the full domain surface — the editor's entire public
18//! shape is spec-first by construction.
