Raven is a rust-based theme manager for linux desktops. It works by defining multiple different 'options', like a polybar configuration, or a wallpaper, and then loads them into sequence when asked to. Even if you're not using a full-on DE, and instead opting for the more minimal WM like i3 or bspwm, you can still get a coherent theme that affects pretty much everything you do. There's a complete list of options available in the README of raven.
Raven has a few different moving parts.
Ravenserver is an online server that people can upload themes to using the command-line tool and later download them. The main instance is hosted here, so go check it out! More themes are always appreciated.
Raven is the command-line tool that you use to manage and load the themes, but it is just an interface to
Ravenlib, which handles all of the heavy-lifting with themes
Graven is an alpha-stage GUI version of raven, which I am very open to feedback on.
git clone https://git.sr.ht/~nicohman/raven && cd raven
cargo install --path . --force
You can also download a binary built from the latest git commit at my website.
The following packages are required for their relevant options:
Rofi is used in the default config and is recommended. You can also add a custom rofi theme with the
Sublime Text 3 :
raven help for a list of available commands:

A main config file is placed in ~/.config/raven/config.json, which has the following options:
polybar: Array of strings, which decideds what bars are run with polybar. The size of the array should be the same as your monitor number monitors : The number of monitors currently in use menu_command: A command that, when raven menu is run, will be piped a list of theme names through STDIN and expects a theme name from STDOUT last: The last theme raven loaded editing: The theme you are currently editing host: The URL of the ravenserver host to use. By default, [https://demenses.net](https://demenses.net)
To configure a theme, start off by creating it with
raven new [theme]. You'll automatically start editing that theme. Run
raven add [option] [file] to add a specific option. This will copy the indicated file to raven's registry, and run/reload/copy it when the edited theme is loaded or refreshed. Run
raven rm [option] to remove an option from a theme. Available options are:
base_ files allow splitting the config from the cosmetics on the options with [base_] For example if you place an i3 config named base_i3 in ~/.config/raven, the contents of i3 for a theme will be appended to it instead of being run on their own. This allows you to have a central config for keyboard shortcuts, and have cosmetics only be stored in the theme.
The lemonbar option should be a shell script that runs lemonbar(s). They will automatically be killed just like polybars when the theme is changed or reloaded.
As many polybars as you have monitors will be started. The names of the bars themselves should be configured in
config.json. The default is ["main", "other"]. If you're sharing your themes with others, it is recommended that you leave the polybar monitor name blank, so that it automatically adapts to other monitor names.
With the cycle command you can control a daemon that will automatically cycle through all of your configured themes. You need to edit
~/.config/raven/time and place the number of seconds there should be between each cycle into that file in order to use it.

Ravenserver has specific API docs available here, if you want to develop your own client for it or something similar.
Docs.rs has documentation for ravenlib, which is useful for either your own projects or contributing.
