# wal (Python 3 version) [![MIT licensed](https://img.shields.io/badge/license-MIT-blue.svg)](./LICENSE.md) [![Build Status](https://travis-ci.org/dylanaraps/wal.py.svg?branch=master)](https://travis-ci.org/dylanaraps/wal.py) `wal` is a script that takes an image (or a directory of images), generates a colorscheme (using `imagemagick`) and then changes all of your open terminal's colorschemes to the new colors on the fly. `wal` then caches each generated colorscheme so that cycling through wallpapers while changing colorschemes is instantaneous. `wal` finally merges the new colorscheme into the Xresources db so that any new terminal emulators you open use the new colorscheme. `wal` can also change the colors in some other programs, check out the [Customization](#customization) section below. **NOTE:** `wal` is not perfect and won't work with some images.

The command below can be used as a test to see if `wal` will work with your setup. Run the command below, does the background color of your terminal become red? ```sh printf "%b" "\033]11;#ff0000\007" ``` If your terminal's background color is now red, your terminal will work with `wal`. ## Installation ### Pip install ```sh pip install pywal ``` ### Manual install Just grab the script (`wal`) and add it to your path. ## Setup **NOTE:** If you get junk in your terminal, add `-t` to all of the `wal` commands. ### Applying the theme to new terminals. `wal` only applies the new colors to the currently open terminals. Any new terminal windows you open won't be using the new theme unless you add a single line to your shell's start up file. (`.bashrc`, `.zshrc` etc.) The `-r` flags tells `wal` to find the current colorscheme inside the cache and then set it for the new terminal. Add this line to your shell startup file. (`.bashrc`, `.zshrc` or etc.) ```sh # Import colorscheme from 'wal' (wal -r &) ``` Here's how the extra syntax above works: ```sh & # Run the process in the background. ( ) # Hide shell job control messages. ``` ### Making the colorscheme persist on reboot. On reboot your new colorscheme won't be set or in use. To fix this you have to add a line to your `.xinitrc` or whatever file starts programs on your system. This `wal` command will set your wallpaper to the wallpaper that was set last boot and also apply the colorscheme again. Without this you'll be themeless until you run `wal` again on boot. ```sh # Add this to your .xinitrc or whatever file starts programs on startup. wal -i "$(< "${HOME}/.cache/wal/wal")" ``` ## Usage Run `wal` and point it to either a directory (`wal -i "path/to/dir"`) or an image (`wal -i "/path/to/img.jpg"`) and that's all. `wal` will change your wallpaper for you and also set your terminal colors. ```sh usage: wal [-h] [-c] [-i "/path/to/img.jpg"] [-n] [-o "script_name"] [-q] [-r] [-t] [-v] wal - Generate colorschemes on the fly optional arguments: -h, --help show this help message and exit -c Delete all cached colorschemes. -i "/path/to/img.jpg" Which image or directory to use. -n Skip setting the wallpaper. -o "script_name" External script to run after "wal". -q Quiet mode, don"t print anything. -r Reload current colorscheme. -t Fix artifacts in VTE Terminals. (Termite, xfce4-terminal) -v Print "wal" version. ``` ## Plugins Listed below are plugins for other programs that add support for `wal` colors. ### Hyper Terminal https://github.com/dneustadt/hyper-wal ## Customization I've written another script \[1\] for personal use only that updates my `lemonbar`, `dunst` and `startpage` colors with the new ones from `wal` when run. What I've done is bind both `wal` and my custom script to the same key so that after `wal` has done its thing my custom script applies the colors to the rest of my environment. ```sh # i3 config. # ... # Cycle wallpapers and apply new colorscheme. bindsym $mod+w exec "wal -i $HOME/Pictures/Wallpapers -o wal-set" ``` Now whenever I press `Win+w` a random wallpaper is chosen and all of the programs on my system start using the new colors immediately. I've also set `wal` and my custom script to start with X. This means that when I boot my PC a random wallpaper is chosen and colors are generated + applied to all of my programs. ```sh # .xinitrc wal -i "$HOME/Pictures/Wallpapers" -o wal-set exec i3 ``` Have a look at my script to see how `wal` is used and how the programs get reloaded with the new colors. \[1\] https://github.com/dylanaraps/bin/blob/master/wal-set **NOTE:** `wal` stores the exported files in `$HOME/.cache/wal/` ### i3 To use `wal` with i3 you have to make some modifications to your i3 config file. i3 can read colors from `Xresources` into config variables! This allows us to change i3's colors dynamically. On run `wal` will detect that you're running i3 and reload your config for you. If you've set it up correctly i3 will then use your new colorscheme. Example: ```sh # Set colors from Xresources # Change 'color7' and 'color2' to whatever colors you want i3 to use # from the generated scheme. # NOTE: The '#f0f0f0' in the lines below is the color i3 will use if # it fails to get colors from Xresources for some reason. set_from_resource $fg i3wm.color7 #f0f0f0 set_from_resource $bg i3wm.color2 #f0f0f0 # class border backgr. text indicator child_border client.focused $bg $bg $fg $bg $bg client.focused_inactive $bg $bg $fg $bg $bg client.unfocused $bg $bg $fg $bg $bg client.urgent $bg $bg $fg $bg $bg client.placeholder $bg $bg $fg $bg $bg client.background $bg # PROTIP: You can also dynamically set dmenu's colors this way: bindsym $mod+d exec dmenu_run -nb "$fg" -nf "$bg" -sb "$bg" -sf "$fg" ``` ### rofi `wal` updates rofi's colors for you out of the box, automatically. ### vim I've created a vim colorscheme for use with with the colors `wal` generates and you can install it using any vim package manager. The colorscheme uses your terminal colors so it'll adapt to the colorscheme changes automatically. Example: ```vim ! Using plug Plug 'dylanaraps/wal.vim' colorscheme wal ``` ### Emacs Install [this package](https://github.com/cqql/xresources-theme), which will make Emacs use your X environment's colors instead of its default colors. ### polybar Polybar can read colors from `Xresources` to set the bar's colors. Example: ```vim fg = ${xrdb:color7} bg = ${xrdb:color2} ``` ### iTerm2 There's a script called `wal2iterm` in `contrib/wal2iterm` which converts the generated colors to an importable iTerm2 colorscheme. The themes are stored in the `wal` cache directory. (`${HOME}/.cache/wal/itermcolors`). Example: ```sh wal -i "IMAGE" -o "/path/to/wal2iterm/wal2iterm" ``` ### Shell Variables `wal` also exports the colorscheme as a list of shell variables that you can source for use in scripts and the shell. Example: ```sh # Add this line to your .bashrc or a shell script. source "$HOME/.cache/wal/colors.sh" ``` In the shell: ```sh # Once the file is sourced you can use the colors like this: dylan ~ >echo "$color0" #282A23 dylan ~ >echo "$color0 $color5" #282A23 #BCC3CE # lemonbar example lemonbar -B "$color7" -F "$color0" ``` ### SCSS variables `wal` also exports the colorscheme as SCSS variables for use in webpages. I'm using this feature to update my startpage with the new colors dynamically. Example: ```scss // Example .scss file // Import Colors @import '/home/dylan/.cache/wal/colors.scss'; body { background: $color0; color: $color7; } ``` ### CSS variables `wal` also exports the colors as CSS variables for use with Stylish or userChrome.css. Example CSS: ```css /* Import the CSS file. NOTE: This must be at line 1 of your stylesheet. */ @import url('file:///home/dylan/.cache/wal/firefox.css') /* Use the variables */ #nav-bar { background-color: var(--color3) !important; color: var(--color7) !important; } ``` ### PuTTY `wal` also exports the colors so they can be used with PuTTY. After running `wal`, a file will be created (`$HOME/.cache/wal/colors-putty.reg`) that can be executed on a Windows machine to create a new PuTTY session with the generated colors. Once the file is executed, you can select `Wal` from the *Saved Sessions* list. ### Scripting `wal` also exports the colors in a plain text format. This is helpful when you want use the plain colors in another script. See the script in `contrib/wal2iterm` for an example. The file is called `colors` and just contains the hex values one per line in the order of 0-15. Example `colors` file: ``` #0C2B32 #9C7648 #B78742 #B4884D #AC8C64 #D19D62 #61828A #F0DEC0 #666666 #9C7648 #B78742 #B4884D #AC8C64 #D19D62 #61828A #F0DEC0 ``` Example usage in a script: ```sh # Create an array with the plain hex colors ordered 0-15. c=($(< "${cache_dir}/colors")) # Remove the leading '#' if needed. c=("${c[@]//\#}") ``` ### Terminal.sexy You can import `wal`'s colors into Terminal.sexy by copy-pasting the contents of the `xcolors` file located in the cache directory.
