@echo off
REM Change your executable name here
set GAME_NAME=game.exe

REM Set your sources here (relative paths!)
REM Example with two source folders:
REM set SOURCES=src\*.c src\submodule\*.c
set SOURCES=core_basic_window.c

REM Set your raylib\src location here (relative path!)
set RAYLIB_SRC=..\..\src

REM Set the target platform for the compiler (Ex: x86 or x64)
set TARGET_PLATFORM=x86

REM About this build script: it does many things, but in essence, it's
REM very simple. It has 3 compiler invocations: building raylib (which
REM is not done always, see logic by searching "Build raylib"), building
REM src/*.c files, and linking together those two. Each invocation is
REM wrapped in an if statement to make the -qq flag work, it's pretty
REM verbose, sorry.

REM To skip to the actual building part of the script, search for ":BUILD"

REM Checks if cl is available and skips to the argument loop if it is
REM (Prevents calling vcvarsall every time you run this script)
WHERE cl >nul 2>nul
IF %ERRORLEVEL% == 0 goto READ_ARGS

echo Usage: build-windows.bat [-hdurcqqv]
echo  -h  Show this information
echo  -d  Faster builds that have debug symbols, and enable warnings
echo  -u  Run upx* on the executable after compilation (before -r)
echo  -r  Run the executable after compilation
echo  -c  Remove the temp\{debug,release} directory, ie. full recompile
echo  -q  Suppress this script's informational prints
echo  -qq Suppress all prints, complete silence
echo  -v  cl.exe normally prints out a lot of superficial information, as
echo      well as the MSVC build environment activation scripts, but these are
echo      mostly suppressed by default. If you do want to see everything, use
echo      this flag.
echo.
echo * This is mostly here to make building simple "shipping" versions
echo   easier, and it's a very small bit in the build scripts. The option
echo   requires that you have upx installed and on your path, of course.
echo.
echo Examples:
echo  Build a release build:                    build-windows.bat
echo  Build a release build, full recompile:    build-windows.bat -c
echo  Build a debug build and run:              build-windows.bat -d -r
echo  Build in debug, run, don't print at all:  build-windows.bat -drqq
