atomでhtml開くときsjisで開くinitスクリプト

gistfile1.txt

# Your init script
#
# Atom will evaluate this file each time a new window is opened. It is run
# after packages are loaded/activated and after the previous editor state
# has been restored.
#
# An example hack to log to the console when each text editor is saved.
#
# atom.workspace.observeTextEditors (editor) ->
#   editor.onDidSave ->
#     console.log "Saved! #{editor.getPath()}"
fs = require('fs')

atom.workspace.onDidOpen ->
  editor = atom.workspace.getActiveTextEditor()

  try
    filePath = editor.getPath()
  catch error
    return
  return unless fs.existsSync(filePath)

  if /.*\.html$/.test(filePath)
    editor.setEncoding('sjis')
    return

  jschardet = require 'jschardet'
  iconv = require 'iconv-lite'
  fs.readFile filePath, (error, buffer) =>
    return if error?
    {encoding} = jschardet.detect(buffer) ? {}
    encoding = 'utf8' if encoding is 'ascii'
    return unless iconv.encodingExists(encoding)

    encoding = encoding.toLowerCase().replace(/[^0-9a-z]|:\d{4}$/g, '')
    editor.setEncoding(encoding)
