Can I make a regex match all characters up to ; except \;? -


i going construct message-passing system messages have following structure:

message type;message content

(matches message type;)

however, user can set message type, , (for sake of loosely coupled systems) want allow them use ; part of message type. this, i'll have message constructor escape \:

tl\;dr;too long; didn't read content

(matches tl\;dr;)

how can have regex match content first ; that's not \;? in example, that's tl\;dr; part only. note there can unescaped ; within message content.

i tried ^.*;, matches content semicolon within message (e.g. tl\;dr;too long;)

/.*?[^\\](?=;)/

you use ; instead of (?=;), latter prevents being part of full match.

if want match start of string, use:

/^.*?[^\\](?=;)/
