[FEAT] animated logos

[acxz]

Be sure to read FAQ before submitting a new issue.

Wanted features:

Right now we support static logos of various formats. It would be wonderful to support animated logos such as .gif files.

Motivation:

The motivation here is that I have a shell script, pokeshell, which supports the output of both static and animated images to the terminal via chafa. I can pipe the static output just fine with pokeshell pikachu | fastfetch --file-raw -, but pokeshell -a pikachu | fastfetch --file-raw - just clears the current terminal screen. (i.e. pikachu.gif | fastfetch --file-raw -)

pokeshell pikachu | fastfetch --file-raw -:

Here is the animated file that I would like to show in fastfetch:

How it looks by itself:

pokeshell_pikachu.mp4

And when trying to use the file with fastfetch:

gifs only work with iTerm image protocol. In WSL2, you may install Wezterm inside Linux and use

{
  "logo": {
    "padding": {
      "top": 2
    },
    "source": "/path/to/pikachu.gif",
    "type": "iterm",
    "width": 20
  }
}

How it looks by itself:

I assume the program supports the animation by drawing every frame manually. This method doesn't work with fastfetch because fastfetch exits immediately after all modules are printed.

[CarterLi]

I tested your script and confirmed your script keeps running if I enables animation mode. You may take a look at the iterm image protocol which provides much higher resolution and is much simpler to use.

[acxz]

I didn't think to check iterm... Thanks for that. Is there no plan to support other animation protocols, like kitty or with native chafa output (via redrawing fastfetch output, maybe)?

[acxz]

The script actually uses chafa or timg, both of which have support for iterm. I'm testing with a limited character set right now.

[CarterLi]

Is there no plan to support other animation protocols, like kitty or with native chafa output (via redrawing fastfetch output, maybe)?

No plan. Fastfetch is designed to exit as fast as possible. Redrawing is not an option here.

native chafa output

chafa is not an image protocol. It just print regular texts.

also side note, in the config file could I list an arbritary command that outputs a filename? i.e. say if I had a pokeshell --filename pikachu which outputs ~/.cache/pokeshell/pikachu.gif.
Could I do "source": "pokeshell --filename pikachu"?

[acxz]

Does kitty require redrawing? I thought it was more similar to iterm in that regards?

[CarterLi]

Could I do "source": "pokeshell --filename pikachu"?

You may use command substitution. For example "source": "$(pokeshell --filename pikachu)"

Kitty has its own animation protocol that I didn't investigate. I tested this command with 0.37.0 and it works for me

kitten icat -n --align left ~/pikachu.gif | fastfetch --raw -

Here's a better version of it that has a more reasonable scale. your welcome person in 5 years.

kitten icat -n --place 50x50@0x0 --align left (logo path here) | fastfetch --logo-width 50 --raw -

also apt's version of kitty is outdated so if you get an error relating to -n, uninstall kitty and reinstall it with
curl -L https://sw.kovidgoyal.net/kitty/installer.sh | sh /dev/stdin

It would also be nice to add this to the wiki
