Oh My Posh Validator
jandedobbeleer/oh-my-posh
If you're customizing your Oh My Posh prompt, this server validates your config files and segment snippets against the official schema before you apply them. It connects to ohmyposh.dev's API and exposes validation operations that catch configuration errors early, so you're not debugging theme syntax when you should be working. Reach for this when you're building custom segments or testing new prompt layouts and want immediate feedback on whether your JSON is going to work. Since Oh My Posh runs across shells and platforms, having schema validation in your editor workflow saves you from the trial and error cycle of edit, save, reload, check terminal, repeat.

What started as the offspring of oh-my-posh2 for PowerShell resulted in a cross platform, highly customizable and extensible prompt theme engine. After 4 years of working on oh-my-posh, a modern and more efficient tool was needed to suit my personal needs.
