RegEx for matching any char except numbers and defined words

Question

I'm trying to batch rename my files using Advanced Renamer, that support regex.

I want to match all characters to exclude those and create a new filename, but maintain numbers of episodes and specifics words to differentiate regular episodes that OVAs, for example.

I tried \D[^OVA] and others similar but nothing works:

Hunter x Hunter 02 = 02

Hunter x Hunter OVA 08 = OVA 08

Hunter x Hunter OVA Greed Island Final 01 = OVA Island 01

Answer 1

I'm guessing that you wish to exclude OVA and all your numbers. Then, this expression may help you to do so or design one:

([^OVA0-9]+)*

This graph shows how the expression would work and you can visualize other expressions in this link:

If you wish to add a list of word to exclude, this expression may do so:

([\S\s]*?)([0-9]+|OVA|Any|Thing|Else|That|You|Like)

You can add any other word that you might want using an | to exclude.

JavaScript Test

const regex = /([\S\s]*?)([0-9]+|OVA|Any|Thing|Else|That|Like)/gm;
const str = `Hunter x Hunter VOA Greed Island Final 01 = OVA Island 01`;
let m;

while ((m = regex.exec(str)) !== null) {
    // This is necessary to avoid infinite loops with zero-width matches
    if (m.index === regex.lastIndex) {
        regex.lastIndex++;
    }
    
    // The result can be accessed through the `m`-variable.
    m.forEach((match, groupIndex) => {
        console.log(`Found match, group ${groupIndex}: ${match}`);
    });
}
