避免在Rails中预编译资产部分(Regex列入黑名单) [英] Avoid precompiling asset partials in Rails (blacklist by Regex)

问题描述

我已经看到了一些有关避免在使用Rails管道时预编译各种资产的问题/答案；但是，我想通过一个正则表达式数组有效地将其列入黑名单，以将路径名匹配排除在预编译之外.对于我来说，最常见的是，这通常是一组部分组件，无论如何它们都将无法进行预编译.

I've seen a few questions/answers around avoiding precompiling various assets while using the Rails pipeline; however, I want to effectively blacklist via an array of Regex's for pathname matches to exclude from precompilation. Most often for me, this is often a set of partials that will fail precompilation anyway.

推荐答案

首先-keithgaputis已熟练地在此处回答了部分问题，但这并不是上述问题的答案.阅读并投票支持他的答案，然后在下面看到我的补充内容:

First off -- keithgaputis has expertly answered a part of this here but it's not quite an answer to the above question. Read and vote up his answer and then see my additions to his below:

Rails.application.config.assets.precompile << Proc.new { |path|
        blacklist = [
                /nvd3\/src\/intro.js$/,
                /nvd3\/src\/outro.js$/,
                /^.*\.less$/,
                /admin\/modules/,
                /admin\/themes/,
                /admin\/responsive\..*css/
        ]
        full_path = Rails.application.assets.resolve(path)#.to_path
        puts "path: #{path}\nfull_path: #{full_path}" if BLACK_MAGIC[:assets][:debug]

        if (path =~ /(^[^_\/]|\/[^_])[^\/]*$/) and (path !~ Regexp.union(blacklist) )

                puts "including asset: " + full_path if BLACK_MAGIC[:assets][:debug]
                true
        else
                puts "excluding asset: " + full_path if BLACK_MAGIC[:assets][:debug]
                false
        end
}

您可以将所有正则表达式添加到黑名单数组中以进行排除，然后将两个部分添加为条件

You can add all of your regular expressions to the blacklist array for exclusion and then the two part if condition

if (path =~ /(^[^_\/]|\/[^_])[^\/]*$/) and (path !~ Regexp.union(blacklist) )

首先将消除以下划线开头的项目(这还不是完美的Regex，可与rubular一起玩)，其次将消除与黑名单表达式匹配的任何内容.编码愉快！

will first eliminate items beginning with underscore (this isn't quite a perfect Regex yet, play with rubular) and secondly will eliminate anything that matches the blacklisted expressions. Happy coding!
