Rails 開發注意要點

About Ruby Syntax

• 編輯器設定 soft tab (space=2)，以 2 格空白符號做為程式內縮距離（不分語言）。
• 函式如果只有一個參數，就不強制打()
• 函式如果有二個以上的參數，通通都要有 ()
  • (避免發生奇怪的paser bug跟保持專案一致性)
• 字串限定用雙引號包覆
• 善用 "#{str1} #{str3} " 等字串改寫技巧取代不需要的字串加法。

New Developer Setup
READING

    You can find the old wiki dump, of which some of these pages are based off of, attached as a pdf at the bottom of this page.
    [new dev pages start around pg 170, additional tips at the end of the pdf... some info is outdated, so look here first]

    The Pragmatic Programmers have a few solid books that are considered essential reading within the ruby community:

        Programming Ruby 1.9 "The Pickaxe Book" (we aren't using 1.9 yet but moving our code from 1.8 to 1.9 is a priority) [ http://pragprog.com/titles/ruby3/programming-ruby-1-9 ]
        Agile Web Dev w/ Rails 4.0 (in beta right now & covers Rails 3.0 exclusively, which we aren't on.  The 3rd ed. is recommended for now.)
