# Portable Caffeine Clone (PowerShell 5.1 + Embedded C#)
## Plan
- [x] Confirm feature parity target from https://www.zhornsoftware.co.uk/caffeine/ (current switches + tray behavior)
- [x] Define implementation architecture (single script, embedded C# helpers, tray UI, single-instance IPC)
- [x] Implement command-line parsing and normalized parameter model
- [x] Implement activity engine (F15/Shift/custom key, key up vs keypress, STES, allow screensaver)
- [x] Implement conditional activation rules (`-watchwindow`, `-activeperiods`/`-activehours`, `-onac`, `-cpu`)
- [x] Implement timers (`-exitafter`, `-activefor`, `-inactivefor`) and state transitions
- [x] Implement tray app UX (double-click toggle, active/inactive menu, timed menu, revert-to-parameters, about, exit)
- [x] Implement single-instance behavior and remote app commands (`-appexit`, `-appon`, `-appoff`, `-apptoggle`, `-apptoggleshowdlg`, `-replace`)
- [x] Implement notifications (`-notify`) and optional status dialog (`-showdlg`, `-ontaskbar`)
- [ ] Verify script loads/parses and document limitations from non-Windows validation environment
## Progress Notes
- Initial scope confirmed from Zhorn feature list (includes v1.98-era switches like `-activeperiods` and `-notify`).
- Implemented `caffeine.ps1` as a portable single-script app with embedded C# WinForms runtime.
- Added single-instance IPC via hidden window + `WM_COPYDATA` for `-app*` commands and `-replace`.
- Added conditional activation (`-watchwindow`, `-activeperiods`, `-activehours`, `-onac`, `-cpu`) and timers (`-activefor`, `-inactivefor`, `-exitafter`).
- Added activity methods (default F15 key pulse, Shift variants/custom keys, `-stes`, `-allowss`) and tray/status UX.
- Updated tray icons to custom coffee-cup active/inactive variants (with `-nohicon` preserving the same icon in both states).
- Added `build-caffeine-exe.ps1` to extract embedded C# from `caffeine.ps1` and compile `dist\PortableCaffeine.exe` with `csc.exe`.
- Added a `Main()` entry point to the embedded `PortableCaffeine.Program` class so the same source compiles directly as an EXE.
- Added `sign-caffeine-exe.ps1` (PowerShell + embedded C# helper) to create/reuse a self-signed code-signing cert, optionally trust it (`CurrentUser`/`LocalMachine`), and sign the compiled EXE.
- Static review patch: fixed ambiguous `Timer` type and prevented `-app*` switches from starting a new instance when no instance is running.
## Review
- Runtime verification is still pending because this environment is macOS and does not have `pwsh` installed, so I could not run a PowerShell parser check or Windows UI/API smoke test here.
- EXE build verification is also pending in this environment (no Windows `.NET Framework` `csc.exe` available here).
- Self-signed certificate creation/trust-store installation/signing verification is also pending in this environment (requires Windows cert stores and `Set-AuthenticodeSignature`).
- The implementation is intended for Windows PowerShell 5.1 (STA) and relies on `System.Windows.Forms`, `user32.dll`, and `kernel32.dll`.
