ModuleExplorer is a PowerShell module that provides an interactive, terminal-based user interface (TUI) to browse and explore PowerShell modules and their commands and parameters.

Install-Module -Name ModuleExplorer

Show-ModuleExplorer

Show-ModuleExplorer opens an interactive TUI to browse all installed modules, explore their commands, and read help documentation without leaving the terminal.

• Interactive Module Exploration: Navigate a list of all installed PowerShell modules with live filtering.
• Command Viewer: Select a module to browse its cmdlets, functions, and aliases with color-coded types.
• Detailed Help: View Examples, Detailed, Full, and Online help for any command directly in the TUI.
• Parameter Browser: Drill into a command's parameters and read per-parameter help.
• Rich TUI: Built on PwshSpectreConsole (Spectre.Console) for a polished terminal experience.

The viewer is a five-state machine (Description → HelpOptions → HelpContent / ParameterList → ParameterHelpContent). All input routing lives in Invoke-ViewerInputHandler; all rendering lives in Update-ViewerLayout. The data layer is abstracted behind a provider hashtable (New-ModuleDataProvider) so the TUI engine can be reused for other data sources.
