Parsing/Dividing GPU module memory parameter

[Kiruyuto]

Hi there,
this has been bugging me for quite a while.
Ive been trying to set up my own config and I just can't get it to work the way I want it to.

Basically, when using "gpu" module, with specific format, we can use {7} to get total memory:

$ fastfetch --help gpu-format
--gpu-format:
Sets the format string for GPU output.
To see how a format string is constructed, take a look at "fastfetch --help format".
The following values are passed:
        {1}: GPU vendor - vendor
        {2}: GPU name - name
        {3}: GPU driver - driver
        {4}: GPU temperature - temperature
        {5}: GPU core count - core-count
        {6}: GPU type - type
        {7}: GPU total dedicated memory - dedicated-total
[...]

While it works fine, it doesn't respect the "maxPrefix" and "ndigits" settings as it always returns values in bytes (Not sure if thats a bug or not).
My first idea right away was to divide it by 1024 to get MiB (eg. "format": "{7/1024/1024}") but that doesn't work

Here's sample config with hardcoded example of what Im trying to achieve:

{
  "$schema": "https://github.com/fastfetch-cli/fastfetch/raw/dev/doc/json_schema.json",
  "logo": {
    "source": "none"
  },
  "display": {
    "size": {
      "maxPrefix": "MB",
      "ndigits": 0
    },
    "temp": {
      "unit": "CELSIUS",
      "ndigits": 0
    },
    "stat": true
  },
  "modules": [
    {
      // This one is missing "temp"
      "type": "gpu",
      "key": "GPU - Default"
    },
    {
      // This one has unwanted mem clock(?)
      "type": "gpu",
      "key": "GPU - Default+temp",
      "temp": true
    },
    {
      // Displayed in bytes instead MiB
      "type": "gpu",
      "key": "GPU - Actual",
      "temp": true,
      "driverSpecific": true,
      "format": "{2} ({7}){?4} - {4}{?} [{6}]"
    },
    {
      // Expected result
      "type": "gpu",
      "key": "GPU - Expected",
      "temp": true,
      "driverSpecific": true,
      "format": "NVIDIA GeForce RTX 4090 (24142 MiB) - {#green}49°C {#}[Discrete]"
    }
  ]
}

Im using latest 2.16 version installed from winget, if that matters.

$ fastfetch -v
fastfetch 2.16.0 (x86_64)

Fixed in the dev branch.

This one has unwanted mem clock(?)

It's GPU core clock
