@99percentpeople/pi-pwsh-adapter

PowerShell shell adapter for the Pi coding agent on Windows.

Make Pi speak PowerShell instead of bash: !/!! commands and the built-in shell tool run through PowerShell 7 (or Windows PowerShell 5.1), with UTF-8 input/output configured automatically.

It replaces Pi's bash compatibility tool and user !/!! commands with PowerShell, configures UTF-8 input/output, and adapts @99percentpeople/pi-background-tasks to use the same runtime when both packages are installed. The compatibility tool reuses Pi's built-in bash tool definition, preserving its optional timeout, streaming updates, output truncation, full-output files, elapsed-time display, and error formatting.

At startup it selects PowerShell once for the whole session:

1. PowerShell 7 or newer through pwsh.exe when available.
2. Otherwise Windows PowerShell 5.1 through powershell.exe.

The selected executable is explicit, so both pipe and PTY background tasks work without relying on Windows PATHEXT expansion.

Requirements

• Windows
• PowerShell 7 in PATH, or Windows PowerShell 5.1

Install

pi install npm:@99percentpeople/pi-pwsh-adapter

To use PowerShell with background tasks, install both independent packages:

pi install npm:@99percentpeople/pi-background-tasks
pi install npm:@99percentpeople/pi-pwsh-adapter

The extension is a no-op when loaded directly on a non-Windows platform.
