There is regex feature to find words instead of "Ctrl + F" in some editor like VS Code, I'm trying to find a word after a specific word with some another lines.
For example, how to use regex to filter those "someFunction" with the specific "message" property as below:
...
someFunction({
a: true,
b: false
})
someFunction({
a: true,
b: false,
c: false,
d: true,
message: 'I wnat to find the funciton with this property'
})
someFunction({
a: true
})
...
The regex I tried is like:
/someFunction[.*\s*]*message/
But it did't work
How can I achieve this aim?

Multiline search was added in v1.29 (released November 2018), as per this answer. – Hoppeduppeanut Commented May 8, 2019 at 3:44
- Your reference link is correct! I need to use "\n" to enable the multiline search. The final regex I used is /someFunction[\S\n\s*]*message/ – Chris Kao Commented May 8, 2019 at 6:57

Reset to default 12Your expression is just fine, you might want to slightly modify it as:
someFunction[\S\s*]*message
If you wish to also get the property, this expression might work:
(someFunction[\S\s*]*message)(.*)
You can add additional boundaries, if you like, maybe using regex101..
Graph
This graph shows how your expression would work and you can visualize other expressions in jex.im:
Performance Test
This script returns the runtime of a string against the expression.
repeat = 1000000;
start = Date.now();
for (var i = repeat; i >= 0; i--) {
var string = "some other text someFunction \n \n message: 'I wnat to find the funciton with this property'";
var regex = /(.*)(someFunction[\S\s*]*message)(.*)/g;
var match = string.replace(regex, "$3");
}
end = Date.now() - start;
console.log("YAAAY! \"" + match + "\" is a match
