Manifest
What an extension declares about itself: identity plus its command
surface. Root search, the Settings command list, and hotkey binding
render from the manifest — no hand-written plumbing. Builders live
in corvo_ext::manifest; the types in corvo_core::page.
#![allow(unused)]
fn main() {
fn manifest(&self) -> ExtensionManifest {
manifest::extension(
"countdown", // == Command::id
"Countdown", // display title
"Days until a date", // one-line description
icon(),
&["Productivity"],
vec![/* CommandSpec entries */],
)
}
}Command specs
| Field | Meaning |
|---|---|
name | the command’s name inside the extension |
title | display name in root search and Settings |
description | what it does, one sentence |
mode | View opens a page; NoView acts and confirms with a toast |
icon | optional override of the extension icon |
arguments | typed argument slots, required first, up to 3 |
keywords | root-search words |
Builders: view_command, action_command, then chain
CommandSpecBuilder::argument(spec, arg) and ::icon(spec, icon).
Arguments
| Kind | Behavior |
|---|---|
text_argument(name, placeholder) | free text |
required_text_argument(name, placeholder) | the launcher keeps asking until filled |
password_argument(name, placeholder) | masked input |
dropdown_argument(name, placeholder, options) | fixed (value, title) choices |
The first argument’s placeholder becomes the search bar hint when the declared command is selected in root search; the typed value rides into the command as the page query / argument segment.
Quick commands
Every declared command is a quick command: root search lists it, and a hotkey can target it:
command:<extension>:<name>executes aNoViewcommand directly — no launcher window; the command’s toast is the confirmation.Viewcommands open their page from the hotkey.
Declare the small verbs of your extension (Play / Pause, Next Track, Saved Countdowns) as NoView commands so users can bind
them.
