# 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" 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.
