@echo off
@echo Salt Windows Build Script, which calls the other *.ps1 scripts.
@echo ---------------------------------------------------------------------
@echo.
:: This script builds salt on any machine. It uses the following scripts:
:: - build_env.ps1: Sets up a Python environment will all dependencies salt will
::                  will require
:: - build_pkg.bat: Bundles the contents of the Python directory into a
::                  nullsoft installer binary

:: The script first calls the `build_env.ps1` script to set up a python
:: environment. Then it installs Salt into that python environment using Salt's
:: `setup.py install` command. Finally, it runs the `build_pkg.bat` to create
:: a NullSoft installer in the `installer` directory (pkg\windows\installer)

:: This script accepts two parameters.
::   Version: The version of Salt being built. If not passed, the version will
::            determined using `git describe`. The leading `v` will be removed
::   Python: The version of Python to build Salt on (Default is 3)

:: These parameters can be passed positionally or as named parameters. Named
:: parameters must be wrapped in quotes.

:: Examples:
::   # To build Salt 3000.3 on Python 3
::   build.bat 3000.3
::   build.bat 3000.3 3

::   # Using named parameters
::   build.bat "Version=3000.3"
::   build.bat "Version=3000.3" "Python=3"

::  # Using a mix
::   build.bat 3000.3 "Python=3"

:: To activate caching, set environment variables
::   SALTREPO_LOCAL_CACHE  for resources from saltstack.com/...
::   SALT_REQ_LOCAL_CACHE  for pip resources specified in req.txt
::   SALT_PIP_LOCAL_CACHE  for pip resources specified in req_pip.txt

:: Make sure the script is run as Admin
