# pywal (A `wal` rewrite in Python 3)
|
|
|
|
[](./LICENSE.md) [](https://travis-ci.org/dylanaraps/pywal)
|
|
|
|
`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 [WIKI](https://github.com/dylanaraps/pywal/wiki).
|
|
|
|
**NOTE:** `wal` is not perfect and won't work with some images.

## Requirements
|
|
|
|
|
|
### Dependencies
|
|
|
|
- `linux`
|
|
- `python 3.6`
|
|
- `imagemagick`
|
|
- Colorscheme generation.
|
|
- `xfce`, `gnome`, `cinnamon`, `mate`
|
|
- Desktop wallpaper setting.
|
|
- `feh`, `nitrogen`, `bgs`, `hsetroot`, `habak`
|
|
- Universal wallpaper setting.
|
|
|
|
|
|
### Terminal Emulator
|
|
|
|
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?
|
|
|
|
```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]
|
|
|
|

|
|
-t Fix artifacts in VTE Terminals. (Termite,
