10:48:08 /shokai/shokai.iconさんの解説がｷﾀ！
2021-07-04
09:16:08 methodの使い方も大体わかった
scrapbox.addListener(type: string, listener: () => void)
event typeに対してevent listener listenerを登録する
優先順位は最低になる
別名：scrapbox.on()
scrapbox.removeListener(type: string, listener: () => void)
event listenerの登録を解除する
別名：scrapbox.off()
scrapbox.removeAllListeners(type?: string)
typeに登録されている全てのevent listenerの登録を解除する
typeに何も渡さないと、全てのeventに登録されている全てのevent listenerを登録解除する
scrapbox.once(type: string, listener: () => void)
1回しか実行されないevent listenerを登録する
scrapbox.prependListener(type: string, listener: () => void)
scrapbox.addListener()と同じだが、event発火後最初に呼び出されるようになる
scrapbox.prependOnceListener()
scrapbox.once()と同じだが、event発火後最初に呼び出されるようになる
scrapbox.rawListeners()
scrapbox.listeners(type: string): (() => void)[]
event typeに登録されているevent listenersのリスト
scrapbox.listenerCount(type: string): number
typeに登録されているevent listenerの数
scrapbox.emit(type: string)
event typeを発火する
scrapbox.eventNames(): string[]
event listenerが登録されているevent nameのリスト
scrapbox.getMexListeners(): number
登録できるevent listenerの最大数
default: 10
scrapbox.setMexListeners(length: number)
登録できるevent listenerの最大数を変える
おそらく内部変数
scrapbox._events
scrapbox._eventsCount
scrapbox._maxListeners
07:23:29 eventは4つ
lines:changed
page:changed
ページ遷移すると発火する
scrapbox.Page.titleの変更が間に合っていないっぽい？
layout:changed
project:changed
別のprojectに移動すると発火する
code:js
}), window.scrapbox.Project || (window.scrapbox.Project = {
get name() {
return j.default.CurrentProject.get().name
},
get pages() {
return (0, w.cloneDeep) (j.default.QuickSearch.pages)
}
}), window.scrapbox.Layout || window.scrapbox.__defineGetter__('Layout', () =>j.default.Layout.get()), j.default.Line.addChangeListener(() =>{
requestAnimationFrame(() =>window.scrapbox.emit('lines:changed'))
}), j.default.Page.addChangeListener(({
store: i,
event: s
}) =>{
var _,
w;
'load' === s && (n !== (null === (_ = i.get()) || void 0 === _ ? void 0 : _.title) && (requestAnimationFrame(() =>window.scrapbox.emit('page:changed')), n = null === (w = i.get()) || void 0 === w ? void 0 : w.title))

}) =>{

06:51:25 これが新しいAPIの定義？
