Raven

A theme manager for linux, currently focusing on i3. Supports multiple different configuration files, and is fast and portable.

Example

ThemeHub

Raven supports installing themes from and publishing themes to ThemeHub, or your own instance of ravenserver. I encourage everyone to share their themes and rices there!

Installation

All you technically require is cargo to be installed. You can install from crates.io by running cargo install raventhemer, or by building manually:

Run:

git clone https://github.com/nicohman/raven.git && cd raven

cargo install --path . --force

The following packages are required for their relevant options:

• Polybar: poly

• i3: i3

• Pywal : pywal

• Feh: wall

• Ncmpcpp : ncmpcpp

• Termite: termite

• Bspwm : bspwm

• Rofi is used in the default config and is recommended. You can also add a custom rofi theme with the rofi option.

• Ranger : ranger

• Lemonbar : lemonbar

• Openbox : openbox

• Dunst : dunst

• Sublime Text 3 : st_tmtheme, st_scs and st_subltheme

• VSCode : vscode

• New option suggestions are very welcome!

You can also download a prebuilt binary from here

Configuration

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:

• poly (Polybar)
• i3 [base_i3] (i3 config)
• xres (Xresources)
• xres_m ( Xresources, to be merged)
• pywal (an image file that will be used as the pywal base)
• wall (Feh wallpaper)
• ncmpcpp (ncmpcpp config file)
• termite (Termite config)
• script (An arbitrary executable file that will be run when this theme is loaded)
• bspwm [base_bspwm] (bspwm config)
• rofi (A rofi theme that will be copied to ~/.config/rofi/theme.rasi)
• ranger (rc.conf)
• lemonbar (A shell script that should spawn your lemonbar)
• openbox [base_rc.xml] (rc.xml)
• dunst [base_dunst] (dunstrc)
• st_tmtheme
• st_scs
• st_subltheme
• vscode (Plain text containing the name of an already installed VSCode theme.)

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.

Polybar bar names

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.

Cycle themes

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.

Sublime Text 3

Plain text containing sublt/<filename>.<extension> (which you must create on your theme folder) or the name of an already installed theme (e.g DA.sublime-theme)

Extensions: st_tmtheme (.tmTheme), st_scs (.sublime-color-scheme) and st_subltheme (.sublime-theme)
