问题 var matches; while(matches = /./g.exec("abc")) { console.log("hey"); } This never terminates. I expect it to terminate after 3 loops. Warning: Don't run it in Chrome because the infinite log lines freeze your entire system. It's safe to run it in IE (it still freezes your webpage but you can go to the location bar and press enter to reload). 回答1: This is how you should execute exec in a loop: var matches; var re = /./g; while(matches = re.exec("abc")) { if (matches.index === re.lastIndex) re

问题 I am trying to use a powershell script to change the password between two strings, I am running into two issues. A complex password seems to break my regex, If I use something as simple as "TestPassword" the regex does what I expect. However using a more complex password "6QAfD5PmMhWzUxTq1FO1bGJQQXRXu6tizN29h6MRUSI=" it breaks and results in SSLEnabled="true" keystoreFile="C:\cert.pfx" $16QAfD5PmMhWzUxTq1FO1bGJQQXRXu6tizN29h6MRUSI=" keystoreType="PKCS12"/> instead of SSLEnabled="true"

问题 I want to extract filter rules configured in /etc/lvm/lvm.conf , like filter = [ "r|/dev/sda|" ] . I want sed to return "r|/dev/sda|" . So I have tried the following script: echo ' filter = [ "r|/dev/sda|" ] ' | sed -r 's:^\s*filter\s*=\s*\[\s*([^\s]+)\s*\]:\1:g' But it didn't work, the script has returned filter = [ "r|/dev/sda|" ] . I've tried a few on line regex tester, the group has been matched correctly. However, if I replace [^\s]+ by .+ , it works. Doesn't [^\s]+ mean more than one

问题 I want to find all matches within a given string including overlapping matches. How could I achieve it? # Example "a-b-c-d".???(/\w-\w/) # => ["a-b", "b-c", "c-d"] expected # Solution without overlapped results "a-b-c-d".scan(/\w-\w/) # => ["a-b", "c-d"], but "b-c" is missing 回答1: Use capturing inside a positive lookahead: "a-b-c-d".scan(/(?=(\w-\w))/).flatten # => ["a-b", "b-c", "c-d"] See Ruby demo 回答2: I suggest a non-regex solution: "a-b-c-d".delete('-').each_char.each_cons(2).map { |s| s
