Usage

Adding a userchrome

nyoom specifies sources for userchromes in a special format.

• GitHub: github:<owner>/<repo>[#ref]
• Codeberg: codeberg:<owner>/<repo>[#ref]
• GitLab: gitlab:<owner>/<repo>[#ref]
• Path to a directory: path:<path>
• URL (to a known archive format of .zip, .tar, .tgz, .tar.gz, .tar.xz, .tar.bz2 or .tar.zst): url:<url> or just <url>

You can add a new userchrome by using the nyoom add command:

$ nyoom add <name> <source>

Then, to specify config options specific to a userchrome, use the nyoom config commands:

$ nyoom config set <name> <key> <value>        # value is treated as string
$ nyoom config set --raw <name> <key> <value>  # value is treated as a value
$ nyoom config unset <name> <key>
$ nyoom config list

These config options will be automatically added to and removed from your user-overrides.js (preferred) or user.js upon switching.

Switching

First, you need to configure the full path to where your Firefox profile is.

$ nyoom profile <directory>

Then, run nyoom switch <name> to switch to a userchrome you previously added. nyoom will retrieve the source, install the contents of the userchrome in the chrome directory, inject settings into user-overrides.js or user.js, and update arkenfox (thereby syncing user-overrides.js with user.js) if arkenfox is detected.

You can run nyoom update on subsequent runs to reapply the userchrome using the latest data from remote, and use nyoom switch out to uninstall the userchrome.
