GI - convert extracted wishes to wish tally format

convert-to-tally.js

const fs = require('fs');
const GACHA_TYPES = [
    "STANDARD",
    "NOVICE",
    "WEAPON",
    "CHARACTER",
]
const GACHA_TYPE = process.argv[2];
if (!GACHA_TYPES.includes(GACHA_TYPE)) {
    console.log("Invalid gacha type. Available types are:\n" + (GACHA_TYPES).map(e => "\t- " + e).join("\n"))
    process.exit(0);
}

fs.readFile(`${GACHA_TYPE}.json`, (err, data) => {
    if (err) {
        return console.log(err);
    }
    const wishList = JSON.parse(data).map((wish) => ({
        item_type: wish.item_type,
        name: wish.name,
        time: wish.time
    })).reverse();

    const h = {}
    for (const wish of wishList) {
        if (!h[wish.time]) {
            h[wish.time] = [wish];
        } else {
            h[wish.time].push(wish);
        }
    }

    const res = [];
    for (const date in h) {
        if (h[date].length < 10 && h[date].length > 1) {
            throw `Inaccurate length of ${h[date].length}, ${JSON.stringify(h[date])}`;
        }
        const type = h[date].length == 10 ? "MULTI" : "SINGLE"
        let i = 1;
        for (wish of h[date]) {
            res.push(`${wish.item_type}${wish.name}${wish.time}\t${i++}`)
        }
    }
    fs.writeFile(`${new Date().toISOString()}-${GACHA_TYPE}-wishtally.txt`, res.join("\n"), (err) => {
        // console.log(err);
    })
});

Usage:

node convert-to-tally.js [STANDARD/NOVICE/WEAPON/CHARACTER]

This will create a txt file for selected banner, ready to paste into wish tally
