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.

Modules

keys

The keymap: every action the editor answers to, and the chords bound to it.

Structs

Anchor

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

Chrome

Which of the editor’s own affordances are on.

CommentId

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

Editor

Formatting

What a toolbar reads to light itself, in one call.

History

ImageStore

Who owns the pictures a document points at.

Layout

What the editor lays the document out with.

Step

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

TextSize

How far the chords move a document, in points — the unit a settings field is written in, so the two never need converting between.

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.

Mode

Which form the document is being edited in.

Source

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

Constants

CONTEXT

DEFAULT_UNDO_LIMIT

How many steps a document keeps.

Functions

adjust_text_size

Move every open document by points, each staying inside the range against its own base.

init

Install the editor’s key bindings — bindings, bound.

reset_text_size

Give every document back to the size its app set it at.

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.

set_text_size

editor::set_text_size(cx, my_steps) — call once at boot.

text_size_adjustment

What every document is currently set away from its base by, in points.

turns

Every block a block can be turned into, and what each is called — the vocabulary the slash menu and the block menu both offer, for an app building a menu of its own. Pair with Editor::set_block, which is what both of bezel’s own menus call.
