这个问题在这里已经有了答案： 如何使用正则表达式验证电子邮件地址？ 74个答案 你很近，不得不添加几个字符： (?:(?:rn)?[ t])*(?:(?:(?:[^()<>@,;:\".[] 00-31]+(?:(?:(?:rn)?[ t] )+|Z|(?=[["()<>@,;:\".[]]))|"(?:[^"r\]|\.|(?:(?:rn)?[ t]))*"(?:(?: rn)?[ t])*)(?:.(?:(?:rn)?[ t])*(?:[^()<>@,;:\".[] 00-31]+(?:(?:( ?:rn)?[ t])+|Z|(?=[["()<>@,;:\".[]]))|"(?:[^"r\]|\.|(?:(?:rn)?[ t]
Most questions regarding this problem are due to missing Xcode; I have Xcode 4.2 installed. Install attempt: rvm install 1.9.3 Installing Ruby from source to: /Users/jamie/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending on your cpu(s)... ruby-1.9.3-p0 - #fetching ruby-1.9.3-p0 - #extracted to /Users/jamie/.rvm/src/ruby-1.9.3-p0 (already extracted) Fetching yaml-0.1.4.tar.gz to /U
关于这个问题的大部分问题是由于缺少Xcode; 我安装了Xcode 4.2。 安装尝试： rvm install 1.9.3 Installing Ruby from source to: /Users/jamie/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending on your cpu(s)... ruby-1.9.3-p0 - #fetching ruby-1.9.3-p0 - #extracted to /Users/jamie/.rvm/src/ruby-1.9.3-p0 (already extracted) Fetching yaml-0.1.4.tar.gz to /Users/jamie/.rvm/archives Extracting y
If I create an application, using Shoes, would I have to license it under a open source license, or can I use it for closed-source/propietary stuff? The framework consists of a lot of moving parts, so it's not entirely clear to me. EDIT: The reason why I'm asking, is because of the notes at this page: Since both anal_pe and XPwn are GPL, I'm afraid this extension must be GPL as w
如果我使用Shoes创建应用程序，是否必须使用开源许可证授权它，或者我可以将它用于封闭源代码/专有代码？ 该框架包含很多移动部件，所以对我来说并不完全清楚。 编辑：我之所以问，是因为本页的笔记： 既然anal_pe和XPwn都是GPL，恐怕这个扩展也必须是GPL。 鞋的其余部分是麻省理工学院。 没关系，我猜是因为打包者并不是真的需要运行Shoes应用程序。 我认为它不会影响包装商GPL的最终产品，但我只是想对此有所看法，而
I'm trying to get some speed up in my program and I've been told that Ruby Fibers are faster than threads and can take advantage of multiple cores. I've looked around, but I just can't find how to actually run different fibers concurrently. With threads you can do this: threads = [] threads << Thread.new {Do something} threads << Thread.new {Do something} threads.
我试图在我的程序中加快速度，并且我被告知Ruby Fibers比线程更快并且可以利用多个内核。 我环顾四周，但我无法找到如何实际运行不同的光纤。 使用线程你可以做到这一点： threads = [] threads << Thread.new {Do something} threads << Thread.new {Do something} threads.each {|thread| thread.join} 我看不出如何用纤维做这样的事情。 我能找到的只有yield和resume ，这似乎只是一堆光纤之间的起始和停
I have 5 lines line1 line2 line3 line4 line5 Using regex I've matched the line3. Now is there I way I can move the line3 just after line2(in other words, do away with the n at the end of line2)? I plan on using line3.sub(/myregex/, "some way to pull up line3 right after line2") method. or I can do line2.sub(/regex_to_select_the_/n_at_the_end/, "") . Will this work?
我有5条线 line1 line2 line3 line4 line5 使用正则表达式我已经匹配line3。 现在是我的方式我可以在line2后面移动line3（换句话说，在line2的末尾删除 n）？ 我打算使用line3.sub(/myregex/, "some way to pull up line3 right after line2")方法。 或者我可以做line2.sub(/regex_to_select_the_/n_at_the_end/, "") 。 这会工作吗？ 有没有更好的/不同的方式来做到这一点？ 只需将用于匹配lin
Is there a quick way to find every match of a regular expression in Ruby? I've looked through the Regex object in the Ruby STL and searched on Google to no avail. 使用scan应该做的诀窍是： string.scan(/regex/) For finding all the matching strings, Use scan method of String class. str = "A 54mpl3 string w1th 7 numb3rs scatter36 ar0und" str.scan(/d+/) #=> ["54", "3", "1", "7", "3", "36",
有没有一种快速的方法来找到Ruby中的正则表达式的每一个匹配？ 我查看了Ruby STL中的Regex对象，并在Google上搜索无济于事。 使用scan应该做的诀窍是： string.scan(/regex/) 为找到所有匹配的字符串，请使用String类的scan方法。 str = "A 54mpl3 string w1th 7 numb3rs scatter36 ar0und" str.scan(/d+/) #=> ["54", "3", "1", "7", "3", "36", "0"] 如果您希望MatchData是由Regexp类的match方法返回的对象的类型，请
I need to match a string of variable length(between 5 and 12), composed of uppercase letters and one or more digits between 1 and 8. How can I specify that I need the whole captured group's length to be between 5 and 12? I have tried with parenthesis but with no luck. I have tried this s([A-Z]+[1-8]+[A-Z]+){5,12}s My idea was to use the quantifier {5,12} to limit the length of the capture
我需要匹配一个可变长度的字符串（5到12之间），由大写字母和1到8之间的一个或多个数字组成。如何指定我需要整个捕获组的长度介于5和12之间？ 我尝试了括号，但没有运气。 我试过这个 s([A-Z]+[1-8]+[A-Z]+){5,12}s 我的想法是使用量词{5,12}来限制括号之间被捕获组的长度，但显然它不能像那样工作。 字符串需要在正常文本内标识 "THE STRING I NEED TO DECODE IS SOMETHING LIKE FD1531FHHKWF BUT NOT LIKE g4G58234JJ"

Newcomer to Jekyll here (previously on Hyde). Ruby files placed in the _plugins/ directory are apparently silently ignored. I am using version 0.11.2 of Jekyll, with ruby 1.8.7 on Ubuntu 12.04. Should an extra config parameter be added to load these plugins? The doc doesn't say so - the sane default should be to look into _plugins, and they should be required automatically. How can on
Jekyll的新人（此前在海德）。 放置在_plugins /目录中的Ruby文件显然被忽略。 我使用的是Jekyll版本0.11.2，在Ubuntu 12.04上使用ruby 1.8.7。 是否应该添加一个额外的配置参数来加载这些插件？ 文档没有这么说 - 理智的默认应该是查看_plugins，并且它们应该是自动需要的。 如何调试Jekyll插件的加载？ 对于我的jekyll实例（也是0.11.2，但是在Mac上使用ruby 1.9.2p290），我不必添加任何额外的配置，但可以尝试将以
