JIRA Issue Key Regex

Question

I'd like to have a regex to match and pull out BUG-123 from this sentence:

some junk here BUG-123 My bug description goes here

Thanks

Which language are you using the regex with? Java? What is `xxx` and `yyy`? And what have you tried? — Martin Ender, Dec 14 '12 at 15:47
I'm going to use Regex with C#. xxx and yyy are just junk text that may appear before the bug number in the commit message. — Adam Levitt, Dec 14 '12 at 15:49
I need to parse any of the above snippets using regex and return the bug number(s). I simplified the issue since it was confusing people. — Adam Levitt, Dec 14 '12 at 15:51

You can use BUG-(\d+)

So it would be

List<string> bugNos=Regex.Matches(yourString,@"BUG-(\d+)",RegexOptions.IgnoreCase)
                       .Cast<Match>()
                       .Select(x=>x.Value).ToList();

The RegExp is below. It will parse through all the lines.

(?m)BUG-([^ ]+)

I just wrote the following code in C#, which returns false: new Regex("/BUG-([^ ]+)/g").IsMatch("BUG-123"). I updated my original post to make this much simpler. – Adam Levitt Dec 14 '12 at 16:03

@AdamLevitt no this would work fine..you are not using the regex properly...remove `/` from the regex – Anirudha Dec 14 '12 at 16:10
@ualinker ur regex is correct..but this is `c#` not `php`..no need of `/` – Anirudha Dec 14 '12 at 16:13
Ok, thanks for the note! I know RegExps but I am not familiar with C#, unfortunately – ualinker Dec 14 '12 at 16:17
there's no need for `m` either – Martin Ender Dec 14 '12 at 16:28
The original post contained much more information at first. That bug IDs may be text and that it may be contained on multiple lines. – ualinker Dec 14 '12 at 16:30

For a related StackOverflow question (Regular expression for a JIRA identifier) , I found a semi-official regex from Atlassian themselves (for Java), and I ported it to JavaScript.

Java version:

((?<!([A-Za-z]{1,10})-?)[A-Z]+-\d+)

JavaScript version (requires that everything be reversed first, though):

var jira_matcher = /\d+-[A-Z]+(?!-?[a-zA-Z]{1,10})/g

I just looked into creating a regex for jira issues and found this entry. I found some testdata to match

VALID:
JIRA-1 BIN-10000 A-1 TACO-7133 X-88 BF-18 ABC-1 BINGO-1 BUG-123
NOT VALID:
JIRA-01 BIN-10000000 abc-123 ABCDEFGHIJKL-999 abc XY-Z-333 abcDEF-33
VALID no \s Ending
JIRA-1

And came up with (research + original work) a .net regex that should match the valid ones and not match the invalid ones:

(?<!([^\s]))([A-Z]{1,10}-[1-9][0-9]{0,6})(?=(\s|$))
