REM Script for building the LLVM installer on Windows,
REM used for the the weekly snapshots at http://www.llvm.org/builds.
REM
REM Usage: build_llvm_package.bat <revision>

REM Prerequisites:
REM
REM   Visual Studio 2019, CMake, Ninja, GNUWin32, SWIG, Python 3,
REM   NSIS with the strlen_8192 patch,
REM   Visual Studio 2019 SDK and Nuget (for the clang-format plugin),
REM   Perl (for the OpenMP run-time), 7Zip.
REM
REM
REM   For LLDB, SWIG version <= 3.0.8 needs to be used to work around
REM   https://github.com/swig/swig/issues/769


REM You need to modify the paths below:
set vsdevcmd=C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\Tools\VsDevCmd.bat

set python32_dir=C:\Users\%USERNAME%\AppData\Local\Programs\Python\Python36-32
set python64_dir=C:\Users\%USERNAME%\AppData\Local\Programs\Python\Python36

for /f "usebackq" %%i in (`PowerShell ^(Get-Date^).ToString^('yyyyMMdd'^)`) do set datestamp=%%i

set revision=%1
set package_version=12.0.0-%revision:~0,8%
set clang_format_vs_version=12.0.0.%datestamp%
set build_dir=llvm_package_%revision:~0,8%

echo Revision: %revision%
echo Package version: %package_version%
echo Clang format plugin version: %clang_format_vs_version%
echo Build dir: %build_dir%
echo.
pause

mkdir %build_dir%
cd %build_dir%
