edui.document

One open document in an editor panel. edui.document.new{ id } makes one; doc:open(path, line?) shows a VFS file or asset in the viewer its kind calls for; doc:build(edui.palette()) is the panel content. Text is editable (doc:save() writes it and runs a .luau file through the LSP) and the document follows its file on disk: a write lands in a buffer with no unsaved edits, and raises a "changed on disk" bar over one that has them. doc:setText tells the owner (onChange) when it moves doc:dirty(), so a panel can mark its tab.

doc:suspend() sets a document aside while its panel is closed: the watch and the viewer's resources go, the path and the unsaved edits stay. doc:resume() picks it back up and reads the file as it is now — a clean buffer adopts what changed meanwhile, an edited one raises the conflict.

Viewers are modes. The built-in ones are code, markdown (rendered, with a Source toggle), image, asset (a live orbitable render for any asset type that declares a preview) and info. edui.document.registerMode{ name, match, build } adds another.

The Code panel is one document; edui.shown opens a panel around another.
