Notes 🗒️ :

• Duplicate theme names will not be loaded

1. Singe conversion

  gowall convert path/to/img.png -t <theme-name>

• Replace a single color with another

   gowall convert /path/to/img.png -r #312424,#1D1C2D

Notes 🗒️ :

• path/to/img.png does not have to be an absolute path. You can use a relative path with the ~ ex. ~/Pictures/img.png
• you can find the list of all the themes via gowall list check number 6. as well

2. Batch conversion

     gowall convert -b path/img.png,path/im2.png -t <theme-name-lowercase>

   ⚠️ Do not leave any white spaces between the comma , , do it like this : path/img.png,path/im2.png

3. Invert colors

    gowall invert path/to/img.png

   You can also batch invert colors with :

    gowall invert -b path/img.png,path/img2.png

   
   

4. Convert a whole Directory

   Use the # delimiter to convert every image file under that directory

    gowall convert ~/Pictures/# -t catppuccin
   
    gowall invert ~/Pictures/test/# 

   Notes 🗒️ : Only png jpeg jpg webp images will be converted any other directory or other file will be ignored

   
   

5. List all theme names

    gowall list

   Notes 🗒️: You can view the colors of a theme by using the -t flag Example:

    gowall list -t catppuccin

   You can also open up a hex preview app in your default browser via the -p flag Example : gowall list -pt catppuccin

7. Image previewing

   Image previewing is available for single image processing and is ON by default

   Examples : gowall convert ~/Pictures/img.png and gowall invert ~/Pictures/img.png

   You can disable it by adding the following inside your ~/.config/gowall/config.yml

   EnableImagePreviewing: false

   
   
   
   

8. Pallete extraction ( Like pywal )

   You can extract the color pallete of an image as shown below :

   gowall extract /path/to/img.png -c 6

   The -c flag specifies how many hex color codes to return ( Personally i recommend between 6-16 with 6-7 being my go to). This will print the color codes to the terminal. In order for you to view all the colors of the hex codes at once you can use the -p flag.

   gowall extract /path/to/img.png -pc 6

   That will open a hex code previwer in your default web browser

9. Wallpaper of the Day

   View beautiful wallpapers that reset daily

   gowall -w

   You can see an example here

   
   

10. Changing formats

    Change the format of an image, the available formats are png jpeg jpg webp

     gowall convert ~/Pictures/img.webp -f png

11. Adding a border

    Using the draw command you can draw a border and specify the color, thickness etc... The below draws a border 5px thick with the color #5D3FD3

      gowall draw ~/Pictures/img.png -c #5D3FD3 -b 5

    

yay -S gowall

More installation options : here

Assuming you have void-packages

cd void-templates/ && cp -r gowall/ void-packages/srcpkgs/
cd void-packages/
./xbps-src pkg gowall
sudo xbps-install -R hostdir/binpkgs gowall

🔨 Clone the repo, build the project and move it inside your $PATH

git clone https://github.com/Achno/gowall
cd gowall
go build
sudo cp gowall /usr/local/bin/
gowall

Notes 🗒️ : You dont have to use sudo cp gowall /usr/local/bin/ if you have $GOPATH setup correctly Eg. you have the following in your .zshrc / .bashrc

export GOPATH=$(go env GOPATH)
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

And simply use go install

go install github.com/Achno/gowall@latest

If you wish to contribute by adding a new theme please open an issue I would also be very happy if you can provide the rgb values of your theme as well :) but not required if it's popular
