Enum HostEffect 

pub enum HostEffect {
    Message(String),
    RunCommand {
        name: String,
        args: Vec<String>,
    },
    SetOption {
        name: String,
        value: String,
    },
    InsertText(String),
}

A typed, validated editor mutation requested by Lisp code. The runtime drains these after eval and applies them — Lisp never touches EditorState directly. New capabilities are one variant here + one native fn in [register_editor_fns] + one apply arm in the runtime; nothing else.

Variants

Message(String)

Show a message (status line / :messages).

RunCommand

Run a registered editor command by name.

Fields

name: String

args: Vec<String>

SetOption

Set an editor option.

Fields

name: String

value: String

InsertText(String)
