`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 colors to the new colorscheme on the fly. `wal` then caches each generated colorscheme so that cycling through wallpapers while changing colorschemes is instantaneous.
`wal` also merges the new colorscheme into the Xresources database so that programs on your system such as `Rofi` or `i3` use the new colors automatically. `wal` finally exports the colors into various formats so that you can use the colors in webpages, scripts, other programs etc.
For more info, check out the [Wiki](https://github.com/dylanaraps/pywal/wiki).
**NOTE:** `wal` is not perfect and won't work well with some images.
To use `wal` your terminal emulator must support a special type of escape sequence. 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?
**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.)
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.
