#!/usr/bin/tclsh
#
# This script is used to generate a VSIX (Visual Studio Extension) file for
# SQLite usable by Visual Studio.
#
# PREREQUISITES
#
# 1. Tcl 8.4 and later are supported, earlier versions have not been tested.
#
# 2. The "sqlite3.h" file is assumed to exist in the parent directory of the
#    directory containing this script.  The [optional] second command line
#    argument to this script may be used to specify an alternate location.
#    This script also assumes that the "sqlite3.h" file corresponds with the
#    version of the binaries to be packaged.  This assumption is not verified
#    by this script.
#
# 3. The temporary directory specified in the TEMP or TMP environment variables
#    must refer to an existing directory writable by the current user.
#
# 4. The "zip" and "unzip" command line tools must be located either in a
#    directory contained in the PATH environment variable or specified as the
#    exact file names to execute in the "ZipTool" and "UnZipTool" environment
#    variables, respectively.
#
# 5. The template VSIX file (which is basically a zip file) must be located in
#    a "win" directory inside the directory containing this script.  It should
#    not contain any executable binaries.  It should only contain dynamic
#    textual content files to be processed using [subst] and/or static content
#    files to be copied verbatim.
#
# 6. The executable and other compiled binary files to be packaged into the
#    final VSIX file (e.g. DLLs, LIBs, and PDBs) must be located in a single
#    directory tree.  The top-level directory of the tree must be specified as
#    the first command line argument to this script.  The second level
#    sub-directory names must match those of the build configuration (e.g.
#    "Debug" or "Retail").  The third level sub-directory names must match
#    those of the platform (e.g. "x86", "x64", and "ARM").  For example, the
#    binary files to be packaged would need to be organized as follows when
#    packaging the "Debug" and "Retail" build configurations for the "x86" and
#    "x64" platforms (in this example, "C:\temp" is the top-level directory as
#    specified in the first command line argument):
#
#                         C:\Temp\Debug\x86\sqlite3.lib
#                         C:\Temp\Debug\x86\sqlite3.dll
#                         C:\Temp\Debug\x86\sqlite3.pdb
#                         C:\Temp\Debug\x64\sqlite3.lib
#                         C:\Temp\Debug\x64\sqlite3.dll
#                         C:\Temp\Debug\x64\sqlite3.pdb
#                         C:\Temp\Retail\x86\sqlite3.lib
#                         C:\Temp\Retail\x86\sqlite3.dll
#                         C:\Temp\Retail\x86\sqlite3.pdb
#                         C:\Temp\Retail\x64\sqlite3.lib
#                         C:\Temp\Retail\x64\sqlite3.dll
#                         C:\Temp\Retail\x64\sqlite3.pdb
#
#    The above directory tree organization is performed automatically if the
#    "tool\build-all-msvc.bat" batch script is used to build the binary files
#    to be packaged.
#
# USAGE
#
# The first argument to this script is required and must be the name of the
# top-level directory containing the directories and files organized into a
# tree as described in item 6 of the PREREQUISITES section, above.  The second
# argument is optional and if present must contain the name of the directory
# containing the root of the source tree for SQLite.  The third argument is
# optional and if present must contain the flavor the VSIX package to build.
# Currently, the only supported package flavors are "WinRT", "WinRT81", and
# "WP80".  The fourth argument is optional and if present must be a string
# containing a list of platforms to include in the VSIX package.  The format
# of the platform list string is "platform1,platform2,platform3".  Typically,
# when on Windows, this script is executed using commands similar to the
# following from a normal Windows command prompt:
#
#                         CD /D C:\dev\sqlite\core
#                         tclsh85 tool\mkvsix.tcl C:\Temp
#
# In the example above, "C:\dev\sqlite\core" represents the root of the source
# tree for SQLite and "C:\Temp" represents the top-level directory containing
# the executable and other compiled binary files, organized into a directory
# tree as described in item 6 of the PREREQUISITES section, above.
#
# This script should work on non-Windows platforms as well, provided that all
# the requirements listed in the PREREQUISITES section are met.
#
# NOTES
#
# The temporary directory is used as a staging area for the final VSIX file.
# The template VSIX file is extracted, its contents processed, and then the
# resulting files are packaged into the final VSIX file.
