Overview

This release introduces real-time syntax highlighting for command validation, inspired by the fish shell.

Key Improvements:

• Invalid Command Highlighting: Commands that do not exist in the current session or $env:PATH are highlighted in Red by default.
• Asynchronous Validation: Logic is offloaded to a background thread (ThreadPool) to prevent UI lag or typing latency.
• Smart Caching: Includes a ConcurrentDictionary cache to store validation results, which is automatically cleared upon AcceptLine to handle new environment changes.
• Thread Safety: Implemented via AutoResetEvent signaling to trigger re-renders only when background validation completes.

How to use:

You can customize the color in your $PROFILE using:

Set-PSReadLineOption -Colors @{ InvalidCommand = 'Red' }

Overview

This release further enhances the PSReadLine experience by introducing a fully interactive, paged completion menu inspired by the fish shell. This replaces the disruptive y/n prompt with a seamless, navigable UI.

Key Features

The New Completion Menu

The menu automatically adapts its layout based on the content:

• Grid Mode: Compact multi-column view for file paths and simple lists.
• Description Mode: Single-column view with inline parameter descriptions (requires Set-PSReadLineOption -ShowToolTips).
• Smart Paging: If the results exceed your terminal height, the menu pages automatically. Use arrow keys or Page Up/Down to navigate.
