Fun Facts Splashscreens

[meleu]

@hiulit if generating the image at boot the overhead would be perfectly bearable!

The fun facts could be in a txt file and the script gets the text there...

Great work! These would be cool for a screen saver as well.

@hiulit

Yes, I did use them as an initial splashscreen. But that is an awesome idea! All of you are wizards.

Please feel free to take this in any direction you want (not like you needed my permission lol). But I am really happy with all the new ideas! Sorry that I am totally useless when it comes to coding.

I also think this is really cool.

the images would be amazing, but even if it is only used on the command line through forture | cowsay it would still be cool

I just wanted to let you know that I've started working on this project.

I'll keep you updated ;)

P.S. Looking good!

P.P.S. @meleu When using convert, it takes a lot of time. I'm working on a Virtual Machine. Maybe it's that. I don't know. Here's a snippet of what I'm doing:

convert splash4-3.png \
    -size 1000x100 \
    -interline-spacing 5 \
    -background transparent \
    -fill white \
    -caption:"${fun_facts[$random_number]}" \
    -gravity south \
    -geometry +0+25 \
    -composite \
    result.png

And here's what time outputs:

real 0m7.172s
user 0m6.300s
sys  0m0.656s

BTW, if anyone wants to tinker, here's the GitHub's repo https://github.com/hiulit/es-fun-facts-splashscreens

@hiulit hey man! Well done!! ;-)

[hiulit]

@meleu Thanks! :D It's super basic now, but it seems to be working. Now it's time to take a look at your generate-launching-imagesscript and improve mine ;)

[meleu]

@hiulit I'm glad to know it can inspire you. I usually spend sometime making my code readable just to help others to understand it (including @meleu in the future). Knowing that you're reading it and getting some inspiration makes me feel like the work was worth it. :D

Let me know if you have any doubt!

[meleu]

@hiulit a small tip: if you want to store fun facts in a text file, one fun fact per line, you can get a random line from the file using the shuf command. This way:

shuf -n 1 fun_facts.txt

EDIT: This aproach would be useful if the users want to customize their fun facts. They wouldn't need to edit the script's code.

;-)

[hiulit]

@meleu Thanks for the tip! I'll try it! :)

[hiulit]

@meleu Done! It works beautifully :D

[Zigurana]

If it takes too long, maybe run the image-generation-script on system shutdown, to be used at next boot-time?

[meleu]

@zigurana good idea! ;-)

@hiulit I have more comments, maybe it's better to move the nerdy conversation to the nerdy topic... :)

[hiulit]

@zigurana Yeah, good idea! Although I really don't have any idea of where I should put my script to do that... (⊙_☉) hehe! Noob at scripting here :P

[hiulit]

More progress! :D
Now the splashscreen is created using the font of the active theme in EmulationStation, and if it has none it takes the Carbon theme font as default.

A little video demo of the script working https://streamable.com/s/bbzzd/fecqc

And here's the the splashscreen of the Pixel theme with a Fun Fact!™ using Pixel's own font.

@hiulit you're doing a good job bro!!

I've submitted a PR to your repo. But, as I'm away from my RetroPie currently, please test it before merging. ;-)

[hiulit]

WOW, thanks man! I will take a look at it and I'll get back to you :)

[hiulit]

@meleu Hey, I've merged your pull request but I had to make a little change because it didn't seem to work properly.

The change I made was adding a ! before -f "$splashscreen" when checking for the splashscreen.

if [[ ! -f "$splash" ]]; then
    splash="$DEFAULT_SPLASH"
fi

Besides that, everything was alright! Thanks! :)

[hiulit]

@meleu When I encountered the problem with Pixel theme and xmlstarlet I tried a different approach for finding the font.

function get_theme_font() {
    get_current_theme
    if [[ -n "$(find "$ES_DIR/themes/$current_theme/art" -type f -name '*.ttf')" ]]; then
        font="$(find "$ES_DIR/themes/$current_theme/art" -type f -name '*.ttf')"
    else
        font=$DEFAULT_FONT
    fi
}

I did the job, but I wasn't happy about repeating the find function , but I don't know any better :P

Do you think that could be a workaround for finding theme fonts?

I know that some themes can have multiple fonts but I think it's ok to use the first one found.
