$.store で状態を残す
$.store は、同じ PC のすべてのセッションが共有するキーと値の置き場です（JSON で合わせて 4 MiB まで）。get(key) は値（無いキーなら空）、set(key, value) は JSON にできる値を受けます。いくつものセッションが書く値は、ファイル（$.fs）より $.store に置きます。
$.store.get$.store.set$.store.delete$.store.keys
最小の形
hooks/register.js
let count = 0
export function register(on) {
on('session.start', async ($, e, next) => {
// every session on this machine shares $.store
count = Number((await $.store.get('turns')) ?? 0)
return next(e)
})
on('turn.complete', async ($, e, next) => {
count += 1
await $.store.set('turns', count)
$.ui.status(count + ' turns so far')
return next(e)
})
}
modscode が公式ドキュメントの API で書いた最小の例です。自由に使えます。
