使用 gsub 从源代码中删除 javascript 控制台语句
我是 ruby 新手，我编写了一个简单的 rakefile ...
我的任务之一是从 javascript 文件中删除“控制台”行，您对当前代码片段有何看法？
def self.remove_debug()
FileList[File.join(DIST_DIR, '**/console-nodebug.js')].each do |file_name|
puts "file: #{file_name}"
content = File.read(file_name).gsub(/console\..*?;/m, "// console removed")
File.open(file_name, 'wb') { |file| file.write(content) }
end
end
还好？？我需要改变一些东西吗？
我测试了代码，一切顺利，但是......我正在寻找好的做法......
谢谢！

我建议有一个调试变量并让 ruby 初始化该变量（我真的对 ruby 不太了解，我把这个留给你，我猜想像将它注入到 html 文件中一样）。然后在你的 js 文件中你可以这样做：
以我的拙见，这比修改文件更好。
希望它有所帮助，祝你好运！

如果它是一个需要缩小的缩小文件，我建议将您的正则表达式替换为“/* console returned */”而不是“// console returned”，以防万一之后还有更多代码线。
除此之外我想你会没事的。有效吗？
I would recommend having a debug variable and have ruby initialize that variable (I really don't know much about ruby, I leave this to you, I guess something like injecting it in the html file). And then in you js file you may do like this:
In my humble opinion this is better than modifying the file.
Hope it helped, good luck!
==EDIT==
If it's a minified file that you need to shrink I would suggest replacing your regex bu "/* console removed */" instead of "// console removed", just in case that there is some more code after that line.
Other than that I think you will be ok. Is it working?
