hubotからcliを叩く方法

Last updated at Posted at 2014-02-18

↓こんな感じのscriptをhubotに叩かせて結果を表示する方法を示します。

php cli/talk.php -a hello
hello

node.jsのspawnを用いて

scripts/cli.coffee
spawn = require('child_process').spawn

module.exports = (robot) ->
  robot.respond /do-talk$/i, (msg) ->
    cli_talk = spawn('php', ['cli/talk.php', '-a', 'hello'])
    cli_talk.stdout.on 'data', (data) ->
      msg.send data
    cli_talk.stderr.on 'data', (data) ->
      console.log('cli_talk stderr: ' + data)

こんな感じで定義してあげれば

Hubot> hubot do-talk
Hubot> hello

このように結果を表示してくれます。
同様にして外部のscriptを叩けるので複雑な処理はcliにしてしまえば「coffeeはちょっと…」という方にもオススメです。
