# Windows Build Configuration for AppVeyor
# http://www.appveyor.com/docs/appveyor-yml
#

# This version starts a separte job for each platform config
# in order to get around the AppVeyor limit of 60 mins per job.

# build version format
version: "{build}"

# Probably not useful for free accounts, but ask anyway.
max_jobs: 4

  - Visual Studio 2013

# If the appveyor config file changes, invalidate the cache.

before_build:
# These steps are a replacement for
# - update_external_sources.bat --all
# Instead of using the above script to build glslang/spirv-tools
# for all platform configs, build only the job's selected platform config.
# Since the script doesn't support building a single platform config,
# use parts of the script to build only the selected platform config.
#
# Also always build the x64 Release platform config in order to
# get the shader compiler binary which is used to build the repo.
#
# For a 4 platform config setup:
# All this results in 7 builds of glslang per commit, which isn't
# as good as building 4 when building all 4 platform configs in
# a single job, but is necessary when splitting the build into 4 jobs.
# It is still better than 16 glslang builds.
