1//! Engine-owned abbreviation types.
2
3/// A single abbreviation entry (insert-mode or cmdline-mode, recursive or noremap).
4///
5/// Mode flags: `insert` = expand in Insert mode, `cmdline` = expand in Cmdline mode.
6/// `noremap` stores whether the definition was made with `noreabbrev`; expansion
7/// is always literal text regardless of this flag, but it is preserved for future use.
8///
9/// NOTE: Abbreviations are currently per-editor (global in vim would share across
10/// buffers; per-editor is equivalent for single-buffer use and is acceptable for
11/// now — cross-buffer global behaviour is a follow-up).
