@tuba89 you if statement probably needs some work, it's a question that's not related to oh-my-posh but PowerShell. I'll happily have a look after my holidays. |

Thanks @JanDeDobbeleer for the reply! You were right, the problem was in my PowerShell function, not in oh-my-posh itself. I fixed it by:
Now all themes load fine This can be closed, appreciate your help! Here’s the full working function (update $themesPath to your own themes folder):
This will print the correct path for your system. On Windows it’s usually: C:\Users<your-username>\AppData\Local\Programs\oh-my-posh\themes function Choose-PoshTheme {
$themesPath = "C:\Users\assia\AppData\Local\Programs\oh-my-posh\themes"
$themes = Get-ChildItem $themesPath -File -Filter "*.omp.json" | Sort-Object Name
if ($themes.Count -eq 0) {
Write-Host "No themes found in $themesPath" -ForegroundColor Red
return
}
Write-Host "Available Themes:" -ForegroundColor Cyan
for ($i = 0; $i -lt $themes.Count; $i++) {
Write-Host "$($i+1). $($themes[$i].BaseName -replace '\.omp$', '')"
}
Write-Host "0. Reset to no theme" -ForegroundColor Yellow
$choice = Read-Host "Enter number (0-$($themes.Count))"
if ($choice -match '^\d+$') {
$choiceNum = [int]$choice
if ($choiceNum -eq 0) {
Write-Host "Reset to default (no theme)" -ForegroundColor Green
}
elseif ($choiceNum -ge 1 -and $choiceNum -le $themes.Count) {
$selectedTheme = $themes[$choiceNum-1]
$themePath = $selectedTheme.FullName
$themeName = $selectedTheme.BaseName -replace '\.omp$', ''
try {
& oh-my-posh init pwsh --config $themePath | Invoke-Expression
Write-Host "Theme switched to $themeName" -ForegroundColor Green
$save = Read-Host "Do you want to save this theme as default? (y/n)"
if ($save -eq "y" -or $save -eq "Y") {
$profilePath = $PROFILE
if (!(Test-Path $profilePath)) {
New-Item -ItemType File -Path $profilePath -Force | Out-Null
}
$profileContent = ""
if (Test-Path $profilePath) {
$profileContent = Get-Content $profilePath -Raw
}
$profileLines = $profileContent -split "`n" | Where-Object {
$_ -notmatch "oh-my-posh init pwsh"
}
$newInitLine = "oh-my-posh init pwsh --config `"$themePath`" | Invoke-Expression"
$profileLines += $newInitLine
$profileLines -join "`n" | Set-Content $profilePath -Encoding UTF8
Write-Host "Saved $themeName as your default theme!" -ForegroundColor Green
Write-Host "Theme will be active in new PowerShell sessions." -ForegroundColor Yellow
}
}
catch {
Write-Host "Error applying theme: $($_.Exception.Message)" -ForegroundColor Red
}
}
else {
Write-Host "Invalid choice" -ForegroundColor Red
}
}
else {
Write-Host "Please enter a number only" -ForegroundColor Red
}
}

What happened?
Many themes do not load with my custom
Choose-PoshThemefunctionEnvironment
Description
I created a PowerShell helper function to quickly switch themes interactively:
Steps to Reproduce
Run the
Choose-PoshThemefunction above.Observe the list of 124 available themes.
Try selecting a theme by number.
1, 10, 11, 12.100 → 124.Invalid choice.Problem
Most themes cannot be loaded — even though they are listed — and return
Invalid choice.Themes that work
Working themes:
Screenshots
Invalid choice example:
Working theme applied:
Expected behavior
All listed themes should be selectable without returning
Invalid choice.Theme
This affects any theme selected through my function, but only some apply correctly.
For example:
Works: darkplus, slim, tokyo-night
Fails: agnoster, paradox, ys (and many others)
What OS are you seeing the problem on?
Windows
Which shell are you using?
powershell
