Permit hiding status (exit) code when zero

[Bilge]

Feature Request

Is your feature request related to a problem? Please describe.

There seems to be no way to hide the zero exit code from the status module. There is the maybe_int variable, but this poorly-documented feature hides more than just the zero (0) exit status; at the least it also hides statuses 1 and 2 also. I only want to hide the exit status when it is zero and nothing else.

Describe the solution you'd like

Probably a new variable that is simply not set when the exit status is zero.

Describe alternatives you've considered

Hey could you share you status config? I think it you set the success_symbol="" it should be hidden when the exit code is zero.

This works for me:

[status]
format='-\[[$int]($style)\]'
success_symbol=''
style="red"
disabled=false

[Bilge]

That's a curious quirk, but I want a success symbol.

[status]
disabled = false
success_symbol = '[](fg:color_green bg:color_bg1 bold)'
style = 'bg:color_bg1'
format = '[$symbol$maybe_int]($style red)'

I am using $maybe_int for now, to hide the zero exit code, but it also hides other (non-zero) codes (which is bad).

Okay, I don't quite understand what you are trying to achieve

Could you perhaps share a screenshot of the part you want to remove and the part you want displayed?

Brotherman, this is not a particularly difficult concept, so let me break it down one last time:

1. When non-zero show code.
2. When zero hide code.
3. Always show a symbol (tick or cross).

It's just that easy. Except it isn't, because it's unsupported.

@Bilge
Ok I think I got it now. I will create a PR that fixes this.

@Bilge Is this the effect you are going for?

(screenshot from my Nov '22 commit of my .toml file)
And here is how I've been doing it.

[($status)](bg:#86BBD8)\
[$character](bg:#86BBD8)\
...
[character] # The name of the module we are configuring is "character"
success_symbol = "[](fg:green bg:#86BBD8)" 
error_symbol = "[✘](fg:red bg:#86BBD8)"
...
[status]
disabled = false
format = '[\[$status:$common_meaning\] ](fg:red bg:#86BBD8)'

If I'm misunderstanding, I apologize.

@HenningCode will this PR affect existing code?
