User aliases

You can use the above aliases as --user by using the prefix scu instead of sc.
For example: scu-list-units will be aliased to systemctl --user list-units.

Unit Status Prompt

You can add a token to your prompt in a similar way to the gitfast plugin. To add the token
to your prompt, drop $(systemd_prompt_info [unit]...) into your prompt (more than one unit
may be specified).

The plugin will add the following to your prompt for each $unit.

<prefix><unit>:<active|notactive><suffix>

You can control these parts with the following variables:

• <prefix>: Set $ZSH_THEME_SYSTEMD_PROMPT_PREFIX.

• <suffix>: Set $ZSH_THEME_SYSTEMD_PROMPT_SUFFIX.

• <unit>: name passed as parameter to the function. If you want it to be in ALL CAPS,
  you can set the variable $ZSH_THEME_SYSTEMD_PROMPT_CAPS to a non-empty string.

• <active>: shown if the systemd unit is active.
  Set $ZSH_THEME_SYSTEMD_PROMPT_ACTIVE.

• <notactive>: shown if the systemd unit is not active.
  Set $ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE.

For example, if your prompt contains PROMPT='$(systemd_prompt_info dhcpd httpd)' and you set the following variables:

ZSH_THEME_SYSTEMD_PROMPT_PREFIX="["
ZSH_THEME_SYSTEMD_PROMPT_SUFFIX="]"
ZSH_THEME_SYSTEMD_PROMPT_ACTIVE="+"
ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE="X"
ZSH_THEME_SYSTEMD_PROMPT_CAPS=1

If dhcpd is running, and httpd is not, then your prompt will look like this:

[DHCPD: +][HTTPD: X]
