Periodic Slic3r Settings Backup (in windows)

I’ve been using Slic3r with my 3d printer, but wanted to be able to easily restore old configuration values, compare changes and so forth.

Slic3r helpfully stores it’s configuration in INI files in the %appdata% directory, so the below batch script launches slic3r, and periodically git commits the configuration directory.

While the batch is running, launching the batch again will start a new instance of Slic3r and then exit.

Prerequisites

• Git must be installed, and available in the path.

slic3r.bat

echo off

set "slic3rpath=C:\path\to\Slic3r.exe"
set "configpath=%appdata%\Slic3r"
set "batchpath=%~dp0"
set "lockpath=%batchpath%slic3r.lock"

start "" "%slic3rpath%"

if exist "%lockpath%" (
  exit /b 1
)

copy NUL "%lockpath%"

:loop
timeout /t 120 /nobreak

tasklist /FI "IMAGENAME eq slic3r.exe" 2>NUL | find /I /N "slic3r.exe">NUL
if "%ERRORLEVEL%"=="0" (
  git -C "%configpath%" commit -a -m "Scheduled update"
  goto loop
)

DEL "%lockpath%"

I run this minimized (not completely hidden) by creating a shortcut to it, and setting the “Run” value to “Minimized” in the shortcut’s properties.
