Regex Pattern to match Ticket IDs in Javascript (Prefix-Dash-Digits)

Question

I am trying to get a Ticket IDs in a log message to be wrapped with a link to the appropiate URL in Javascript. I am still relatively a newbie when it comes to regex.

Input:

MYPROJECT-123 My Commit

Output:

(MYPROJECT-123)[http://url/MYPROJECT-123] My Commit

I am scratching my head in figuring out why my regex pattern will not work. Any clues?

var logMessage = "MYPROJECT-123 My Commit";
var projectId = "MYPROJECT";

var ticketPattern = new RegExp('/^('+projectId+'-*\d)$', 'g');

var mdLogMessage = logMessage.replace(ticketPattern, "($1)[http://url/$1]");

console.log(mdLogMessage);

Answer 1

Modify your regexp as below. But I don't know javascript regexp mechanism. I believe someone explain it.

before:

var ticketPattern = new RegExp('/^('+projectId+'-*\d)$', 'g');

after:

var ticketPattern = new RegExp('^('+projectId+'-*\\d*)');

Answer 2

Try it like this:

var ticketPattern = new RegExp('/'+projectId+'(?=-\d*\s*My Commit)', 'g')

so the regex pattern will be for example:

MYPROJECT(?=-\d*\s*My Commit)

see demo with 'MYPROJECT' as the projectId here: http://regex101.com/r/lM7rJ3
