Hide battery segment when no information.

Hide battery segment when no information.

You could achieve that with a custom command segment. That one accepts a shell command (and the shell to run it in, here being powershell) . If the command outputs a value, it will show that value.

[JanDeDobbeleer]

I could add a switch to the properties which would allow this. For example:

"hide_error": true

Not sure if I want to make a general switch, I do get where you're coming from but it can get confusing.

What's also an option is to remove the segment from the theme altogether. A quick copy-paste, adjust and setting that as the theme will also hide it forever. Although that might take away its portability.

hide_error works.

I get your point about the general switch as it may open a can of worms. I like the idea of being able to dynamically determine visibility of a segment based on condition but embedding PowerShell code in JSON is quite ugly and no point in creating your own DSL for this 😀

@JanDeDobbeleer, one use case for a general switch or config setting for segment visibility is the following:

Say I want to add an 💾 indicator in my prompt to show that (Get-PSReadLineOption).HistorySaveStyle is set to SaveIncrementally or SaveAtExit and remove it if it's not set?

[AjayKMehta]

I created a theme (cool.json) with a command segment as suggested:

https://gist.github.com/AjayKMehta/1b5324a485a9db6e7d326276ab5786cf

The command is specified as "if ((Get-PSReadLineOption).HistorySaveStyle -ne 'SaveNothing'){'💾'} else {''}"

It seems to run the command the first time and not work subsequently. Even if I disable saving via Set-PSReadLineOption -HistorySaveStyle SaveNothing, I still see 💾 in the prompt.

Any help would be appreciated. Thanks.

It should not save state but run the command every time. I'll check!

I can reproduce this. As this is ran on a new instance of pwsh, it will only work IF this is set globally via for example your $PROFILE. Let me see if I can make it so it runs directly in your shell (which could break if you don't know what you're doing).

[AjayKMehta]

Thanks. That's what I figured as I tried changing the command to Get-Date and it worked fine.
