Returning bot's missing permissions

Hey, i made a function, which is supposed to check for the missing permissionsn in the array of permissions i give it. Instead, it either returns all permissions, or no permissions at all. Code for function: https://srcb.in/8ylqAtQbhb How i utilize the function: https://srcb.in/Jlacln3RD9 Permissions for the channel i'm checking in (Thread channel): pic attached How the bot responds: pic attached

1. I don't see the point of checking both global and channel specific permissions. A permission can be allowed globally, but denied in the channel. Your code does wrong thing. 2. permissions.has((a || b) && c) checks if (a or b) and c has in the permissions (means one of). You need to check (permissions.has(a) || permissions.has(b)) && permissions.has(c). 3. Your returnMissingPermissions does a lot of unnecessary things. You can just filter permissions, map by keys adding the formatting and then join the array.

PermissionsBitField#missing() Gets all given bits that are missing from the bitfield.

alright i was testing a bit with this function. this is my function now (for testing):

function returnMissingPermissions(permissions: PermissionsBitField) {
    console.log(permissions.missing(perms));
}

function returnMissingPermissions(permissions: PermissionsBitField) {
    console.log(permissions.missing(perms));
}

this is how i call my function:

returnMissingPermissions(permissions)

returnMissingPermissions(permissions)

where permissions is:

const permissions = new PermissionsBitField();
permissions.add(perms);

const permissions = new PermissionsBitField();
permissions.add(perms);

and perms is:

const perms = [
    PermissionsBitField.Flags.CreatePublicThreads,
    PermissionsBitField.Flags.CreatePrivateThreads,
    PermissionsBitField.Flags.SendMessagesInThreads,
    PermissionsBitField.Flags.SendMessages,
];

const perms = [
    PermissionsBitField.Flags.CreatePublicThreads,
    PermissionsBitField.Flags.CreatePrivateThreads,
    PermissionsBitField.Flags.SendMessagesInThreads,
    PermissionsBitField.Flags.SendMessages,
];

however, the log is an emtpy array

zeyadOP•11mo ago

these are my perms btw

zeyadOP•10mo ago

Isn't the function supposed to check which permissions from the array perms is missing from permissions the bot has (which is permissions)? WAIT oh I thought I was passing the bot's permissions let me edit the code

returnMissingPermissions((await interaction.guild?.members.fetchMe())?.permissions as PermissionsBitField)

returnMissingPermissions((await interaction.guild?.members.fetchMe())?.permissions as PermissionsBitField)

this is how i now call my function still logging an empty array alright so to test this, i denied the everyone role the perms, and now it's logging the 3 perms missing. So now i believe i'm supposed to check for both, instead of checking only for channel permission overwrites alright tysm okay tysm Okay it's a bit late, but i've now edited the code, to check for permissionsOverwrites. When i allow the Create Posts permissions on the channel, both CreatePrivateThreads and CreatePublicThreads return as missing and the permission SendMessages (not SendMessagesInThreads) passes (doesn't return as missing) even though when that permission in the channel was denied, it was returned missing This is the function:

function returnMissingPermissions(permissions: PermissionsBitField) {
    const $ = permissions
        .missing([
            PermissionsBitField.Flags.CreatePublicThreads,
            PermissionsBitField.Flags.CreatePrivateThreads,
            PermissionsBitField.Flags.SendMessagesInThreads,
            PermissionsBitField.Flags.SendMessages,
        ])
        .toString()
        .replace(/[A-Z]/g, ' $&')
        .slice(1)
        .split(', ')
        .map(string => string.replace(string, `* **${string}**`))
        .join('\n');

    console.log($);
    return $;
}

function returnMissingPermissions(permissions: PermissionsBitField) {
    const $ = permissions
        .missing([
            PermissionsBitField.Flags.CreatePublicThreads,
            PermissionsBitField.Flags.CreatePrivateThreads,
            PermissionsBitField.Flags.SendMessagesInThreads,
            PermissionsBitField.Flags.SendMessages,
        ])
        .toString()
        .replace(/[A-Z]/g, ' $&')
        .slice(1)
        .split(', ')
        .map(string => string.replace(string, `* **${string}**`))
        .join('\n');

    console.log($);
    return $;
}

and this is how i call it:

const botPermissions = channel.permissionsFor(
                    (await interaction.guild?.members.fetchMe()) as GuildMember,
                );
returnMissingPermissions(botPermissions)

const botPermissions = channel.permissionsFor(
                    (await interaction.guild?.members.fetchMe()) as GuildMember,
                );
returnMissingPermissions(botPermissions)

what about Send messages in posts permission?
