How to do "regex.test(string)" in Macrodroid? - Solved

[AkashiDom]

const username = "myBot";
const regex = new RegExp(`^\\/\\w+(\\@${username})?(\\s|$)`);
const string = "/ping@otherbot ms";

if (regex.test(string)) {
    console.log(true);
} else {
    console.log(false);
};

Is there anyway to replicate that JavaScript code to macrodroid?

If you don't understand, I just want to know how to do like regularExpression.test(string) in macrdroid

You can use the text manipulation (extract text) action and see if the result is empty or you can use a constraint with compare values (string) and enable regex matching (recommended). You can also use the JavaScript action to run your code ([lv=varname] is evaluated in the code).

I want to do the 2nd but I don't quite understand
Do I have to put / at front and end of my regular expression or regex?

It should work like what you first posted.

It should work like what you first posted.

So let's say I make regex of checking if it a word, all I need to input is \w+ and not /\w+/?

I'm not a profession with regex and javascript and mostly do with try and error.
Best is to simplify the regex and then go on. For your word example it should be

"\\w+"

so the backslash as a special char has to be escaped. I took your example code, reduced the regex to

"\\w+"+username

and changed the string to

"test myBot"

it worked with console output

true

hope it helps,

quiero hacer el 2do pero no lo entiendo bien
¿Tengo que poner / al principio y al final de mi expresión regular o expresión regular?

Thanks everyone, I finally understand how to put regular expression in compare value or macrodroid variable

Hi, @AkashiDom ,

It may be too late now.....

Regex was getting awfully difficult, so I tried to interpret it simply. I attach a sample macro.

The result of the macro should be True, right?
The Regex part seemed to be the problem, not the structure of your source code.

No, you don't have to.

No, you don't have to.

How do I insert flag then?
