# This Powershell script is used by the Vulkan Run Time Installer/Uninstaller to:
#   - Copy the most recent vulkan-<majorabi>-*.dll in C:\Windows\System32
#     to vulkan-<majorabi>.dll
#   - Copy the most recent version of vulkaninfo-<abimajor>-*.exe in
#     C:\Windows\System32 to vulkaninfo.exe
#   - Set the layer registry entries to point to the layer json files
#     in the Vulkan SDK associated with the most recent vulkan*dll.
#
# This script takes one parameter - a single number specifying the major abi version.
#

Param([string]$majorabi)

$vulkandll = "vulkan-"+$majorabi+".dll"

# The name of the versioned vulkan dll file is one of the following:
#
#   vulkan-<majorabi>-<major>-<minor>-<patch>-<buildno>-<prerelease>-<prebuildno>
#   vulkan-<majorabi>-<major>-<minor>-<patch>-<buildno>-<prerelease>
#   vulkan-<majorabi>-<major>-<minor>-<patch>-<buildno>-<prebuildno>
#   vulkan-<majorabi>-<major>-<minor>-<patch>-<buildno>.dll
#
# <major>, <minor>, <patch>, <buildno> and <prebuildno> are 1 to 10 numeric digits.
# <prerelease> is any combination of alpha and numeric characters.
# If <prerelease> and/or <prebuildno> are present, this identifies a prerelease,
# and the vulkan dll file will be considered less recent than one with the same
# <major>, <minor>, <patch>, <buildno> numbers without the <prerelease> and/or
# <prebuildno>.


# We first create an array, with one array element for each vulkan-*dll in
# C:\Windows\System32, with each element containing:
#    <major>=<minor>=<patch>=<buildno>=<prerelease>=<prebuildno>=
#     filename
#    @<major>@<minor>@<patch>@<buildno>@<prerelease>@<prebuildno>@
# [Note that the above three lines are one element in the array.]
# The build identifiers separated by "=" are suitable for sorting, i.e.
# expanded to 10 digits with leading 0s. If <prerelease> or <prebuildno> are
# not specified, "zzzzzzzzzz" is substituted for them, so that they sort
# to a position after those that do specify them.
# The build identifiers separated by "@" are the original values extracted
# from the file name. They are used later to find the path to the SDK
# install directory for the given filename.
