Given a string in Javascript like
{include} anything in {curly braces} but not when they are escaped like {this} and work for any position of the {brace}
I want to retrieve
I have been trying to find a way, but without look behind I am stumped.
The most important thing is to NOT get the escaped {} content. I'd be fine with something which includes the braces in the matches, if necessary.
Unfortunately, all I have managed so far is an expression like this
(?:[^//]){.*?}
But that doesn't match if the { is at the beginning of the target text.
Can anyone help me? Thanks.
I assume the escape char is /.
You may use the following regex with a capturing group that will hold your values:
/(?:^|[^\/]){([^}]*)}/g
^^^^^^^
See the regex demo
Details:
(?:^|[^\/]) - either the start of string or a char other than /{ - a literal {([^}]*) - Group 1 capturing any 0+ chars other than } (add { into the class to match the shortest window between { and })} - a literal }.var rx = /(?:^|[^\/]){([^}]*)}/g;
var str = "{include} anything in {curly braces} but not when they are escaped like /{this} and work for any position of the {brace}";
var m, res = [];
while ((m = rx.exec(str)) !== null) {
res.push(m[1]);
}
console.log(res);
