lintとか #tng15

js-support.markdown

Lint for JavaScript

• eslint
• jscs
• jshint
• jslint
• Closure Linter
• coffeelint
• tslint

lintにかかわらず、こういう開発便利系何使ってる? 何知ってる?

で、pronto gemってのがある Ruby

これjsのutilも使いたい

pronto-jshint を参照しよう! -> jshintrb ??? イマココ

↓みたいな感じにしたい

pronto pick-patch | any-command | pronto github_pr

For Ruby

• rubocop
• brakeman
• rails best practice

Web service

• hound-ci

eslintの場合 checkstyle, jslint-xml がparseしやすい

rubocopに神formatterあった
https://github.com/eitoball/rubocop-checkstyle_formatter

rubocop とrubocop-checkstyle_formatter, file nameがフルパスだ

$ rubocop --require rubocop/formatter/checkstyle_formatter --format RuboCop::Formatter::CheckstyleFormatter lib/github_api.rb
<?xml version='1.0'?>
<checkstyle>
  <file name='/Users/sane/work/tachiko/pigeon.tachikoma.io/lib/github_api.rb'>
    <error line='4' column='0' severity='info' message='Class definition is too long. [164/100]' source='com.puppycrawl.tools.checkstyle.Metrics/ClassLength'/>
    <error line='42' column='2' severity='info' message='Method has too many lines. [11/10]' source='com.puppycrawl.tools.checkstyle.Metrics/MethodLength'/>
    <error line='52' column='4' severity='info' message='Favor modifier `unless` usage when having a single-line body. Another good alternative is the usage of control flow `&amp;&amp;`/`||`.' source='com.puppycrawl.tools.checkstyle.Style/IfUnlessModifier'/>
    <error line='82' column='2' severity='info' message='Assignment Branch Condition size for fork_from_this is too high. [22.65/15]' source='com.puppycrawl.tools.checkstyle.Metrics/AbcSize'/>

    <error line='187' column='2' severity='info' message='Method has too many lines. [11/10]' source='com.puppycrawl.tools.checkstyle.Metrics/MethodLength'/>
  </file>
</checkstyle>

errorなしだとこんな出力になる

<?xml version='1.0'?>
<checkstyle>
  <file name='/Users/sane/work/tachiko/pigeon.tachikoma.io/Rakefile'/>
</checkstyle>
