我如何在使用Rails 3.1 Asset Pipeline编译的JavaScript文件的顶部添加样板注释或许可证？

Question

我正在使用Asset Pipeline构建一些JavaScript，并将这些JavaScript移交给许多第三方开发人员。我想在生成的（可能是混淆的）输出文件的顶部放置警告注释，但尚不清楚如何使用链轮/ coffeescript组合来实现此目的。

# This is a manifest file that'll be compiled into including all the files listed below.
# Add new JavaScript/Coffee code in separate files in this directory and they'll automatically
# be included in the compiled file accessible from http://example.com/assets/application.js
# It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
# the compiled file.
###
  The following code was compiled from source by MF. 
  Please do not edit this JavaScript directly.  
####
#= require util/extensions
#= require util/date_manipulation
#= require util/format
#= require points_data
#= require graphics/canvas_graphics
#= require graphics/explorer_canvas_graphics
#= require renderer

我得到以下结果：

(function() {
  /*
    The following code was compiled from source by MF. 
    Please do not edit this JavaScript directly.  
  */
}).call(this);

我想要的是这个（或附近的东西）：

/*
    The following code was compiled from source by MF. 
    Please do not edit this JavaScript directly.  
  */
(function() {
  // ******** my compiled code from all those required files! *******
}).call(this);

我将如何使用它？

Answer 1

最简单的方法是在编译后向文件添加注释。

Rails的默认压缩器-Uglifier-具有：copyright选项，用于保留文件的第一行注释行，因此您可以使用该行将注释（及所有其他版权）保留在其中。

config.assets.js_compressor = Uglifier.new(:copyright => true)

Answer 2

JetBrains的工具集具有一个“版权”插件https://plugins.jetbrains.com/plugin/88-copyright/

它可以将您的版权/标题注入源文件。我已经为IntelliJ Idea和RubyMine尝试过它，并且对我有用。

此插件可能会应用于整个项目，目录或最近更改的文件。
