Struct SlashCommands 

pub struct SlashCommands { /* private fields */ }

Pi-compatible slash-command completion over a fixed Command palette.

/ at a line start opens ranked name completion, the first argument completes against candidates, and usage text ghosts after the cursor (pi buildSubcommandInlineHint).

Implementations

impl SlashCommands

pub fn new(commands: impl Into<Box<[Command]>>) -> Self

Wraps a command palette for Editor::set_completion.

Trait Implementations

impl EditorCompletion for SlashCommands

fn hint(&mut self, text: &str, cursor: usize) -> Option<Str>

Pi-style usage ghosting: bare /name shows the command’s own usage; a partial argument shows its remaining characters plus usage; a chosen argument ghosts the usage words not yet typed.

fn suggest(&mut self, text: &str, cursor: usize) -> Option<Suggestions>

Dropdown suggestions for the current text and byte cursor, or None to close the dropdown.

fn tab( &mut self, text: &str, cursor: usize, selected: Option<&Suggestion>, ) -> TabAction

Tab pressed. selected is the highlighted row while this engine’s dropdown is open. Defaults to pi’s behavior: accept the open row, otherwise pass Tab through to the embedding app. The built-in emoji dropdown always accepts without consulting the engine.
