手順

  1. 両耳同時に長押ししてオフ
  2. 両耳同時に長押ししてオン => そのまま長押しし続けて2回目のポンポンポッポンまで押し続ける
  3. ケースにしまって同時に出す => ピロリロリンがなったら右耳ペアリング

fukajun / Gratanのソースコードを読んだときメモ.md
Last active April 18, 2020 14:30

ざっくりapplyを実行したときに起きていること

  • gratanのコマンド本体は、 bin/gratan

  • apply の本体は、lib/gratan/client.rb にある Client#apply

  • 現在のユーザーやテーブルへの権限付与状態は、lib/gratan/exporter.rb にある、Exporter` が取得してきている。 client.rbにある walk_*で、Expoterが取得してきた現在の状態と、gratanの定義ファイルで指定されている内容を 比較してユーザー作成や権限付与を行っている。

YAPC のスケージュールのページでchrome developperツールから流すとハイライトできるようになります。( http://yapcasia.org/2015/talk/schedule?date=2015-08-21 ) だからなに？
var render = function() {
$('.talk').css('background-color', 'white')
result = ''
Object.keys(list).map(function(id) {
var $el = $('.talk').has('#' + id)
$el.css('background-color', 'pink')
result += $el.find('.title').text() + '\n'
})
console.log(result)
localStorage.wanted = JSON.stringify(list);
