Just like V2, oh-my-posh is available in the PowerShell gallery.
V2's problem statement
Oh My Posh is the offspring of Oh My Posh 2, a prompt theme engine for PowerShell. It started out by being inspired by tools like Oh my ZSH when nothing was available specifically for PowerShell.
Over the years, I switched operating system/main shell quite a lot, even on Windows via the WSL. This made it so that my prompt wasn't portable enough, I wanted the same visual/functional experience regardless of the shell I was working in.
Additionally, V2 has Powershell module files as themes. That way of working was inspired by oh-my-zsh and other prompt rendering tools, but that approach has a few important downsides.
- hard to extend/adjust when you're not proficient
- the need to expose a lot of functions/settings to allow ease of personalization
- limited to Powershell
A brave new world
This brings us to the first change, to allow a cross-platform experience, Oh My Posh is written entirely in Go. That way, cross-platform binaries can be shipped which render the same prompt using the same config anywhere.
The configuration is changed from $ThemeSettings towards a .json file that only contains the configuration for the
blocks and segments you want to render. See concept for more context on that part.
Let's have a look at the V2 commands and how to move towards V3.
Import
Stays the same! Alright. All you need to do is update oh-my-posh.
Update-Module -Name oh-my-posh -Scope CurrentUser
Configuration
Here we have a few options. If you're using an out-of-the-box theme, you can simply change the current command to the new one, provided your V2 theme has already been added to oh-my-posh.
I use an out-of-the-box theme
Change the current prompt setting function to the new one.
# Set-Theme Agnoster
Set-PoshPrompt -Theme agnoster
I use a custom theme/settings
The first thing to do is to look for the theme you based your theme on. If you don't remember which one, preview them all and take the one closest to yours.
Get-PoshThemes
If you see one you like, set it, then export its config so you can customize/extend the blocks and segments.
Set-PoshPrompt -Theme jandedobbeleer
Export-PoshTheme -FilePath ~/.oh-my-posh.omp.json
Adjust the config (~/.oh-my-posh.omp.json) to your liking by going through the configuration guide.
Set your custom theme and enjoy.
Set-PoshPrompt -Theme ~/.oh-my-posh.omp.json
I have no idea just yet
Great! There's an option for that too. You can easily list all available themes and pick the one you like best.
Get-PoshThemes
Choose and set the one you like.
Set-PoshPrompt -Theme jandedobbeleer
All set, now what
You can either tweak the theme to your liking, add segments or submit an issue for new functionality. Do not hesitate to ask for assistance when you notice an issue or unexpected behavior.
