I am trying to append formatting to all /* TODO : ... */ tags, but I am having trouble in the multi-line area. I can do single line sed's; but for multiline sed and awk, I don't know.

问题 Ideally, I would like to create an object from ipconfig that allows us to drilldown to each adapter's attributes like this: $ip.$lan.$mac for the lan adapter's mac address. To start, I would like to develop a way to capture these 3 groups (adapter type, adapter name, adapter attributes) per adapter match into Powershell variables (objects are preferred): https://regex101.com/r/wZ3sV1/1 Here are some ideas to capture three parts of the Ethernet adapter section, but they are only capturing

How do I fix this multiline regular expression in Ruby?

阅读更多关于 How do I fix this multiline regular expression in Ruby?

I have a regular expression in Ruby that isn't working properly in multiline mode. I'm trying to convert Markdown text into the Textile-eque markup used in Redmine. The problem is in my regular expression for converting code blocks. It should find any lines leading with 4 spaces or a tab, then wrap them in pre tags. markdownText = '# header some text that precedes code var foo = 9; var fn = function() {} fn(); some post text' puts markdownText.gsub!(/(^(?:\s{4}|\t).*?$)+/m,"<pre>\n\\1\n</pre>") Intended result: # header some text that precedes code <pre> var foo = 9; var fn = function() {} fn(

How can I match multi-line patterns in the command line with perl-style regex?

阅读更多关于 How can I match multi-line patterns in the command line with perl-style regex?

问题 I regularly use regex to transform text. To transform, giant text files from the command line, perl lets me do this: perl -pe < in.txt > out.txt But this is inherently on a line-by-line basis. Occasionally, I want to match on multi-line things. How can I do this in the command-line? 回答1: To slurp a file instead of doing line by line processing, use the -0777 switch: perl -0777 -pe 's/.../.../g' in.txt > out.txt As documented in perlrun #Command Switches: The special value -00 will cause Perl

问题 I have some piece of ill-formed html, sometimes the " is missing. Also, it sometimes shows capital cases while other times lower cases: <DIV class="main"> <DIV class="subsection1"> <H2> <DIV class=subwithoutquote>StackOverflow</DIV></H2></DIV></DIV> I would like to match both multi-line and ignoring the case. But the following patern does not seem to be working. (For the concatenation, I also tried | instead of &) const string pattern = @"<div class=""?main""?><div class=""?subsection1""?><h2

How is CheckBox with multi-line text done in Windows Forms?

阅读更多关于 How is CheckBox with multi-line text done in Windows Forms?

How do I extend the text in a Windows Forms CheckBox to more than one line? You need to use \r\n in order to add a new line. You might have to do this in the code behind. So your code would be like this: myLabel.Text = "New\r\nLine\r\nExample"; First you should turn autosize property to False. Then resize the box and use \r\n for going to next line. 来源： https://stackoverflow.com/questions/5937637/how-is-checkbox-with-multi-line-text-done-in-windows-forms
