There are no flags to match multi-line text is in JS. But it can be done with a character class.
In both the cases below we expect
\d.line to match
0\nline but it doesn't work - because newlines are not matched by the
. character class.
"line 0\nline1".match(/\d.line/) // null // ES6 `line 0 line1`.match(/\d.line/) // null
[^] character class, which is equivalent to
. but with the newline added in
"line 0\nline1".match(/\d[^]line/) // ["0 // line"] // ES6 `line 0 line1`.match(/\d[^]line/) // ["0 // line"]
