##### context
The `context` segment (user@host string) is conditional. This lets you enable
it, but only display it if you are not your normal user or on a remote host
(basically, only print it when it's likely you need it).
The `context` segment (user@host string) is conditional. By default, it will
only print if you are not your 'normal' user (including if you are root), or if
you are SSH'd to a remote host.
To use this feature, make sure the `context` segment is enabled in your prompt
elements (it is by default), and define a `DEFAULT_USER` in your `~/.zshrc`:
You can set the `POWERLEVEL9K_CONTEXT_HOST_DEPTH` variable to change how the
hostname is displayed. See (ZSH Manual)[http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information]
for details. Default is set to %m which will show the hostname up to the first ‘.’
for details. The default is set to %m which will show the hostname up to the first ‘.’
You can set it to %{N}m where N is an integer to show that many segments of system
hostname. Setting N to a negative integer will show that many segments from the
end of the hostname.
| Variable | Default Value | Description |
|----------|---------------|-------------|
|`DEFAULT_USER`|None|Username to consider a "default context" (you can also use `$USER`)|
|`POWERLEVEL9K_CONTEXT_HOST_DEPTH`|%m|Customizable host depth on prompt|
You can use POWERLEVEL9K_HIDE_HOST for hiding the hostname in the prompt
when you are not in a ssh session. For example:
POWERLEVEL9K_HIDE_HOST="yes"
|`DEFAULT_USER`|None|Username to consider a "default context".|
|`POWERLEVEL9K_CONTEXT_HOST_DEPTH`|%m|Customizable host depth on prompt.|
|`POWERLEVEL9K_ALWAYS_SHOW_CONTEXT`|false|Always show this segment.|
