While i do attempt to make this usable widely, don't rely on it. If you want to use this and have it work as you want it, it's expected that you can read manual pages and know at least a bit of shell scripting.
Because font support detection is a bit complicated, the `prompt` variable in this zstyle allows you to manually toggle on a specific prompt (now only p9k is available)
This should be the location of the mpv socket that is available via the `input-ipc-server`. It will check if the socket exists, and if it does it will use it.
NOTE: While this is fast, it has it's drawbacks. It currently relies on lots of assumptions and that should be understood. JSON parsing is done assuming that the title is a string and that the string has no special characters.
#### :custom:prompts:mail glob
This should be a glob pattern that would match any new mails. This works the best with the Mailbox format as every new mail is a file. mbox or spoolfiles may be supported in the distant future, but i don't plan to do that.
