gitwho – Git Author Manager

gitwho.ps1 is a tiny, self‑contained PowerShell script that lets you switch the global Git author (user.name / user.email) on any Windows box that multiple developers share.

---

✨ Features

• Simple interactive menu with colour highlighting.
• Marks the currently active author with *.
• Add new profiles from within the tool – no manual JSON edits.
• Zero install: copy the script into your repo and run ./gitwho.ps1.
• Profiles stored system‑wide in C:\ProgramData\git-who\profiles.json so every repo & shell sees the same list.

---

Quick start

# inside your project folder
curl -o gitwho.ps1 https://raw.githubusercontent.com/<you>/gitwho/main/gitwho.ps1

./gitwho.ps1      # launch the menu

On first run the tool creates an empty profile store. Use A (Add) to create your first profile; the author is immediately switched.

Note: if PowerShell blocks the script, set your execution policy once:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

Command reference

Command	What it does
gitwho	Interactive menu (Select / Add / Quit)
gitwho alice	Fast‑switch to profile alice
gitwho -List	List all profiles and highlight the active one

Selecting a profile runs:

git config --global user.name  "<Name>"
git config --global user.email "<Email>"

so every subsequent commit uses that identity until you switch again.

Profile file format

{
  "alice": { "name": "Alice Smith", "email": "alice@example.com" },
  "bob"  : { "name": "Bob Chen",   "email": "bob@example.com"   }
}

The file is created and maintained automatically by the script. You can edit it manually if you like, just keep the structure.
