:prompt [pattern] What is syntax for variables in prompt?

I'm a bit late but I hope it could still help.

You can retrieve the help of any plugin by typing :h [plugin]. So to get help for the prompt command, you'll need to type :h prompt.

Here's the output:

The command customizes prompt.
Format can contain following specials:
%d      current time
%e      evaluation time
%h      host name
%l      line number
%m      maximum memory
%t      total memory
%u      user name

The default value (to this date) is [%l].
