KeyAxis.bat

@echo off
REM ===========================================================================
REM  KeyAxis.bat  -  double-click launcher for the KeyAxis desktop app
REM  Turns a Hall-effect keyboard into analog pedals + a live travel monitor.
REM
REM  What this does:
REM    1. Jumps to the folder this .bat lives in (so it works from anywhere).
REM    2. Confirms Python is installed and on PATH (friendly message if not).
REM    3. Checks that pywebview / hid / vgamepad import; installs them if not.
REM    4. Launches app.py with pythonw.exe so NO black console window lingers.
REM  Just double-click it. First run may take a minute while deps install.
REM ===========================================================================

REM --- 1. Work from this script's own directory -----------------------------
cd /d "%~dp0"

echo.
echo   ============================================
echo      KeyAxis - analog pedals from your keyboard
echo   ============================================
echo.

REM --- 2. Make sure Python exists -------------------------------------------
where python >nul 2>&1
if errorlevel 1 (
    echo   [X] Python was not found on this PC.
    echo.
    echo       KeyAxis needs Python 3.9 or newer ^(64-bit^).
    echo       Get it from:  https://www.python.org/downloads/
    echo       IMPORTANT: on the first install screen, tick
    echo       "Add python.exe to PATH", then re-run this launcher.
    echo.
    pause
    exit /b 1
)

REM --- 3. Ensure the runtime dependencies are present -----------------------
REM  We test-import them quietly. If any fail, we pip-install from requirements.
python -c "import webview, hid, vgamepad" >nul 2>&1
if errorlevel 1 (
    echo   [*] First-time setup: installing dependencies...
    echo       ^(pywebview, hidapi, vgamepad - this happens once^)
    echo.
    python -m pip install --upgrade pip
    python -m pip install -r "%~dp0requirements.txt"
    if errorlevel 1 (
        echo.
        echo   [X] Dependency install failed. Check your internet connection
        echo       and that pip works, then run this launcher again.
        echo.
        echo       NOTE: vgamepad needs the ViGEmBus driver for the pedals to
        echo       work. Grab it from:
        echo         https://github.com/nefarius/ViGEmBus/releases
        echo       ^(The MONITOR tab works without it; PEDALS need it.^)
        echo.
        pause
        exit /b 1
    )
    echo.
    echo   [OK] Dependencies installed.
    echo.
)

REM --- 4. Launch with pythonw so there's no console window -------------------
REM  pythonw.exe = the windowed Python interpreter (GUI, no terminal).
echo   [*] Launching KeyAxis...
start "" pythonw.exe "%~dp0app.py"

REM  Give it a moment; if pythonw is somehow missing, fall back to python.
if errorlevel 1 (
    echo   [!] pythonw not available - falling back to python.
    python "%~dp0app.py"
    pause
)

exit /b 0
