オッサンホイホイなEmojiを出力する Slash Command をGASで作成

お題

SlackのSlashコマンドで、昔懐かしいゲーム風のEmojiをランダムに生成します。
Webサービス側は Google Apps Script で実装します。

Slackの外部Integrationの無料枠と
Google Apps Scriptで実現可能なお手軽構成です。

Google Apps Script の実装

ライブラリを追加

Underscore.js を追加

M3i7wmUA_5n0NSEaa6NnNqOBao7QLBR4j でライブラリを検索し、Underscore を追加します

コード

function doGet(e) {
  var _ = Underscore.load();
  r = Math.random()
  var game;
  if (r > 0.5) {
    game = bomb(_);
  } else {
    game = dokan(_);
  }
  var res = {"text": game};
  return ContentService.createTextOutput(JSON.stringify(res)).setMimeType(ContentService.MimeType.JSON);
}

function bomb(_) {
  var bombTemplate = "<%=parts[0]%>:black_large_square:<%=parts[1]%>:black_large_square:<%=parts[2]%>\n" +
    "<%=parts[3]%><%=parts[4]%><%=parts[5]%><%=parts[6]%><%=parts[7]%>\n" +
    "<%=parts[8]%>:black_large_square:<%=parts[9]%>:black_large_square:<%=parts[10]%>\n" +
    "<%=parts[11]%><%=parts[12]%><%=parts[13]%><%=parts[14]%><%=parts[15]%>\n" +
    "<%=parts[16]%>:black_large_square:<%=parts[17]%>:black_large_square:<%=parts[18]%>\n";
  var parts = [":bomb:", ":fire:", ":skull:", ":hole:", ":ghost:", ":japanese_goblin:", ":moyai:", ":dragon:", ":athletic_shoe:"];
  parts = _.sample(parts, 7);
  parts.push(":walking:");
  parts.push(":key:");
  parts.push(":door:");
  for (var i = 0;i<10;i++) {
    parts.push(":grey_question:");    
  }
  parts = _.shuffle(parts)
  var t = _.template(bombTemplate);
  var result = t({parts: parts});
  return result;
}

function dokan(_) {
  var dokanTemplate = ":cloud::cloud::cloud::cloud:<%=sunMoon%>:cloud::cloud:\n" +
    ":large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle:\n" +
    ":large_blue_circle::large_blue_circle:<%=onQuestionBlock%><%=onBlockEnemy1%>:large_blue_circle::large_blue_circle::large_blue_circle:\n" +
    ":large_blue_circle::black_large_square::question::black_large_square::large_blue_circle::large_blue_circle::japanese_castle:\n" +
    ":large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle::large_blue_circle::black_large_square::black_large_square:\n" +
    ":runner::large_blue_circle::large_blue_circle:<%=onBlockEnemy2%>:black_large_square::black_large_square::black_large_square:\n" +
    ":black_large_square::large_blue_circle::large_blue_circle::black_large_square::black_large_square::black_large_square::black_large_square:\n"

  var sunMoon = sunMoonSample(_);
  var onQuestionBlock = onQuestionBlockSample(_);
  var onBlockEnemy1 = onBlockEnemySample(_);
  var onBlockEnemy2 = onBlockEnemySample(_);

  var t = _.template(dokanTemplate);
  var result = t({sunMoon: sunMoon, onQuestionBlock: onQuestionBlock, onBlockEnemy1: onBlockEnemy1, onBlockEnemy2: onBlockEnemy2});
  return result;
}

function sunMoonSample(_) {
  return _.sample([":sunny:", ":crescent_moon:"]);
}

function onQuestionBlockSample(_) {
  return _.sample([":mushroom:", ":star2:", ":seedling:"]);
}

function onBlockEnemySample(_) {
  return _.sample([":turtle:", ":blowfish:", ":fire:"]);
}
