Crate editor 

A Notion-style block editor for gpui, over the markdown document model.

editor::init(cx);                       // once, at startup
let editor = cx.new(|cx| editor::Editor::new("# Title", cx));

markdown holds the document, its markdown wire form, and the painting — all of it testable without a window. What lives here is the half that needs one: focus, keys, the platform input handler, the mouse, undo, and the menus.

Structs

Anchor

A comment’s range in the document, and which wash it paints.

CommentId

The app’s key for a thread. Opaque — nothing here looks inside one.

Editor

History

Layout

What the editor lays the document out with.

Step

The state a step restores, which is a whole moment rather than a diff.

Enums

EditKind

What an edit did, so a run of the same kind can coalesce into one step instead of giving the document back a character at a time.

EditorEvent

What the editor tells its host about.

Source

A picture with no address of its own, and what the app is asked about.

Constants

DEFAULT_UNDO_LIMIT

How many steps a document keeps.

Functions

init

Install the editor’s key bindings. Scoped to the editor’s own key context, so binding tab here does not make tab mean “indent” for the whole app.

set_image_store

editor::set_image_store(cx, my_store) — call once at boot. Without it a screenshot cannot be pasted at all: there is nowhere to put the bytes, and a document holds a URL.

set_layout

editor::set_layout(cx, my_layout) — call once at boot.

Type Aliases

ImageStore

The URL to write down for source, and None for one the app will not keep — a dropped file then stays where it already is, and a screenshot is let go.
