Allowing for spaces in this regex

Question

Consider the following: this.state.message.match(/^\/m\s+(\w+):\s*(.*)/)

This looks for a message that contains: /m name: message where its failing if your name has a space in it: /m name something: message. What would be the proper way to update this such that the name can have spaces or other characters other then just name

for example: \m Character name: message fails, but \m Sample: message does not.

thoughts?

Should the line start with a forward slash or a backslash? One of your examples uses `/`, the other uses ``\`` — CertainPerformance, Nov 23 '19 at 23:05

Simply add space to the character list, no?

/^\/m\s+(\w+[\w| ]*):\s*(.*)/

Change \w to [A-Za-zÀ-ÖØ-öø-ÿ] to accept also accents and diacritics Link

Repeat \w+\s+(word characters, followed by spaces) zero or more times:

^\\m\s+((?:\w+\s+)*\w+):\s*(.*)

Would break if character name ends with space – Thanh Trung Nov 23 '19 at 23:25
True, but that sounds quite unlikely, I've never seen any login system permitting trailing (or leading) spaces in a username or display name – CertainPerformance Nov 23 '19 at 23:31
True, but if basing on that assumption, there will be no system allowing empty login either ;) – Thanh Trung Nov 23 '19 at 23:32

Try this:

/^\/m\s+(\w+\s+)*?(\w+):\s*(.*)/

This adds an additional capturing group, and there's no longer any group capturing the username alone, which is probably not what OP wants – CertainPerformance Nov 23 '19 at 23:21
