Shell Enhancement

Shell Enhancement

The shell group turns PowerShell 7+ into a modern terminal. Full reference: docs/SHELL.md.

sudo .\setup.ps1 -Group shell

What it sets up

• Oh My Posh with the half-life theme (game-inspired prompt with git status)
• Fira Code font (programming ligatures), auto-configured in Windows Terminal
• PSReadLine — history-based prediction, tab-completion menu, reverse search
• Bash-like aliases — ll, la, grep

PowerShell profile

The group writes (or appends to) your $PROFILE. It is idempotent: if the winforge block is already present, it is left untouched. Key bindings added:

• Ctrl+R / Ctrl+S — reverse / forward history search
• Ctrl+A / Ctrl+E — beginning / end of line
• Ctrl+← / Ctrl+→ — jump word

Changing the theme

Oh My Posh ships 100+ themes (dracula, nord, catppuccin, tokyo, …). Download one and point the config at it:

oh-my-posh init pwsh --config "$env:APPDATA\oh-my-posh\config.json" | Invoke-Expression

Requirements

• PowerShell 7+ (the profile guards features behind $PSVersionTable.PSVersion.Major -ge 7)
• A Nerd Font (Fira Code NF) for prompt glyphs — installed by this group
