I built out a tool for myself to manage my nvim configuration, and I wanted to quickly see which one I am running in my starship prompt. Here's the config I ended up with. It warns if the NVIM_APPNAME environment variable is not set, and it shows which nvim I am using if it is set.


[custom.nvim-manager-system]
when = '[[ ! -n "${NVIM_APPNAME}" ]]'
style = "bold yellow"
symbol = '[ ](fg:#15AABF)'
format = '$symbol[USING SYSTEM NVIM]($style)'

[env_var.NVIM_APPNAME]
style = "green"
symbol = '[ ](fg:#15AABF)'
format = '[$symbol${env_value}]($style)'
variable = "NVIM_APPNAME"
