#![allow(rustdoc::private_intra_doc_links)] //! This is the place where everything editor-related is stored (data-wise) and displayed (ui-wise). //! The main point of interest in this crate is [`Editor`] type, which is used in every other Zed part as a user input element. //! It comes in different flavors: single line, multiline and a fixed height one. //! //! Editor contains of multiple large submodules: //! * [`element`] — the place where all rendering happens //! * [`display_map`] - chunks up text in the editor into the logical blocks, establishes coordinates and mapping between each of them. //! Contains all metadata related to text transformations (folds, fake inlay text insertions, soft wraps, tab markup, etc.). //! //! All other submodules and structs are mostly concerned with holding editor data about the way it displays current buffer region(s). //! //! If you're looking to improve Vim mode, you should check out Vim crate that wraps Editor and overrides its behavior. pub mod actions; pub mod blink_manager; mod bracket_colorization; mod clangd_ext; pub mod code_context_menus;
