Prerequisites

Before diving into theme customization, ensure you have Oh My Posh installed on your system. If you haven't installed it yet, follow the installation guide appropriate for your operating system.

Finding and Selecting a Theme

1. Browse Online: Visit the official themes page to preview available themes.
2. List Themes Locally: If Oh My Posh is installed, you can list all available themes using the following command in your terminal:

This command will display a list of themes along with their file paths.

Applying a Theme

To apply a theme, you'll need to modify your configuration file to initialize Oh My Posh with your chosen theme.

notepad $PROFILE

If the profile doesn't exist, create one with:

New-Item -Path $PROFILE -Type File -Force

2. Initialize Oh My Posh: Add the following line to your profile script, replacing paradox with your chosen theme's name:

oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\paradox.omp.json" | Invoke-Expression

3. Save and Reload: Save the profile script and reload it:

. $PROFILE
