In Operation
wallust is command-line software. Running the command wallust on its own shows the various commands and options that are available.
The first thing to try is to run wallust pointing it at either a directory or a specific image, such as:
Running the following command sets the terminal colors based on the image. In the example below, we’re using the hyper terminal emulator.
$ wallust run relax-woman-jumping-sea-beach.jpg
The theme is only applied to the currently open terminals, but its easy to modify your shell startup file so that the theme is applied to new terminal windows. wallust stores the sequences in the cache directory as a file called ‘sequences‘.
We can also apply a custom built-in theme. There’s a wide range to choose. 3024-dark, dkeg-escen, dkeg-paints, base16-github, dkeg-sprout, sexy-kasugano, base16-harmonic-dark, base16-atelier-seaside-dark, monokai, base16-unikitty-light, and many many others. See the full list with the command: $ wallust theme list, Or let’s choose a random theme.
$ wallust theme random
What else does the software offer?
- Rich templating – you can use a subset of Jinja2 or pywal syntax.
- Cache scheme palettes.
- Read pywal/terminal-sexy colorschemes.
Summary
wallust is a handy utility. As pywal is not under active development and wallust is a drop-in replacement, it makes sense to switch over.
You can use wallust generated colors in a program by templating the colors in its config file.
wallust is slow generating colors compared to alternatives mainly because it generates a scheme palette multiple times to find an attractive palette. Rather than use HSV (like pywal) wallust uses lch or other colorspaces to avoid generating similar colors in the palette.
wallust is inspired by pywal. The software is also a drop-in replacement for pywal.
There’s good documentation courtesy of man pages for the software and its commands. That’s refreshing.
