:art: A smart theme generator

art

Caution

You will most likely have to edit the EDITME file since this script is at this moment only adapted for my dotfiles.

What is it ?

art is a theme generator that takes an image, generates colors from it and creates a theme with two variations from those colors, a dark and a light one. It then updates some configuration files and any open terminal with desired colors. Each generated theme is saved in a special folder, that can be accessed at any time.

How does it work ?

1. Load an image
2. Generate a certain number of colors
3. Choose 5 colors
   • The darkest
   • The redest
   • The greenest
   • The blueest
   • The lightest
4. Tweak those colors and create a grey color from the darkest one
5. Check the colors
   • If some colors are too similar, adjust them
6. Generate files

How to install ?

Dependencies

imagemagick: Used to generate the first array of colors

Instructions

art's Issues

Permission denied

Hi! I wanted to try out this on macOS. I know it's not supported, so feel free to tell me to figure this out myself.

I'm only concerned with the part of the script that figures out the values for the colors, not the actual updating, so I see no issue in this working correctly. All I did so far is changing line 69 in args to path=$(${args[$i]}) because there's no realpath in macOS. The way I did you have to specify the full path of the file, but that looks like a minor inconvenience.

However, I'm getting this in response:

xrandr: Failed to get size of gamma for output default
args: line 69: /Users/[my name]/Pictures/Wallpapers/hills.jpg: Permission denied
ERROR: The provided file doesn't exist

I feel like I can safely ignore both the first and last line, but naturally I can't get past the permission denied. The file in question is:

-rw-r--r--@ 1 [my name] staff 600903 17 Mar 22:38 hills.jpg

So I can't really figure out the issue. Any ideas?

EDIT: yeahhhh, it should have been path=${args[$i]}. I'm sorry, it works now.

Missing shebang

Small error at the top of art script prevents it from running where bash is not default system shell. Shebang at top should read #! not #.
