set ps1_style variable to available styles in your .nerdrc
You can test using ps1_style function:

Font rendering

If your terminal does not manage correctly nerd font symbols, you may switch to more commonly supported powerline font symbols, or even disable the segment separator symbols.
You can use : ps1_display function/var to switch prompt display symbol characters:

$ ps1_display -h
usage: ps1_display <option>
    <option>: nerdicons, nerd, powerline, nofont, ascii

Customizing prompt

You can add informations on the prompt using ps1_info variable:

• ps1_info="MYVAR MYVAR2..." : will display content of variables
• ps1_info="(myfunc) (myfunc2)" : will display output of functions myfunc myfunc2

You can add custom colorized segment defining ps1_addon() function:

• ps1_addon() { pgrep rsyslogd >/dev/null || echo 'red:syslog'; } output format of function: <bgcolor>[/<fgcolor>/<sepcolor>]:<message>[|message] empty output discards the segment.

Changing prompt powerline, ps1_powerline variable represents the prompt:

• segment setting : symbol/bgcolor/fgcolor/sepcolor:function
  • function called is ps1_function (ps1_ prefixed)
  • colors : black red green yellow blue magenta cyan white, prefix l for light color
  • symbols : < > ( )
  • when color is set to auto, the function output must be <color>:<text> else only <text>
• right alignment separator : |
• ps1_powerline="(/auto:exit_status (/blue:userhost )/auto:git_branch )/lblack:cwd > | (/lblue/black/blue:info (/auto:freemem (/blue:time )"
• ps1_powerline="auto:exit_status blue:userhost >/auto:git_branch >/lblack:cwd > | </lblue/black/blue:info </auto:freemem </blue:time"
