V4 required_if rule missing?

[AntonioDell]

What happened?

In V3 there was the required_if rule as built-in rule available. After some searching I cannot seem to find it in V4 packages. Also no mention of it's removal as far as I could find.

Was this rule removed on purpose? If yes: What was the reasoning behind it and is there an alternative (maybe chaining multiple rules) to it or do I need to re-create it myself?

Reproduction steps

Compare rules between V3 and V4. In V3 the required_if rule exists, in V4 not.

Version

Vue.js 3.x and vee-validate 4.x

I also need to know how to do if_unless, but it seems it doesnt do a validation on the last keystroke 🤔

Dropped them during the upgrade to v4 and never implemented them since, will consider adding them in the next minor release.

Any news on this?

Did anyone made a custom implementation of a required_if in the v4 please ?

[guyaumetremblay]

If it can help somebody, I did this :

defineRule("required_if", (value, [target, targetValue]: [string, any], ctx) => {
    if (targetValue === ctx.form[target]) {
        return required(value);
    }
    return true;
});

It works well in object notation like this:

{ required_if: ['enabled', true] },

In string notation, the targetValue seems to always been a string so the comparison will failed.
