Custom prompt element for OpenFOAM environment

the definition of prompt element function has to be made at the end of ~/.p10k.zsh file, which is as follows

custom prompt element for OpenFOAM environment

function prompt_OpenFOAM(){ if ( ! $OpenFOAM_STATE ) then return fi p10k segment -b 13 -f 0 -i '▽' -t 'OF' }

and its entry has to be given in the lists of Right prompt elements, as given in the line 52 of file p10k.zsh

this function requires a custom environment variable, called OpenFOAM_STATE which is to be defined in the zshrc file as below

custom Prompt variables definition

export OpenFOAM_STATE=false # used for prompt element

and the command that activates the OpenFOAM environment will trigger this "switch" variable that activates the function prompt element as given below.

alias of="source /opt/OpenFOAM-v2012/OpenFOAM-v2012/etc/bashrc; echo "OpenFOAM initiated"; export OpenFOAM_STATE=true"

make sure that the variable definition is before the alias command
