# Originally written by Curt Hagenlocher, and various bits
# and pieces by Mark Hammond (and now Greg Stein has had
# a go too :-)
# Note that the main worker code has been moved to genpy.py
# As this is normally run from the command line, it reparses the code each time.
# Now this is nothing more than the command line handler and public interface.
# XXX - TO DO
# XXX - Greg and Mark have some ideas for a revamp - just no
# time - if you want to help, contact us for details.
# Main idea is to drop the classes exported and move to a more
# traditional data driven model.
"""Generate a .py file from an OLE TypeLibrary file.
This module is concerned only with the actual writing of
a .py file. It draws on the @build@ module, which builds
the knowledge of a COM interface.
"""
usageHelp = """ \
Usage:
makepy.py [-i] [-v|q] [-h] [-u] [-o output_file] [-d] [typelib, ...]
-i -- Show information for the specified typelib.
-v -- Verbose output.
-q -- Quiet output.
-h -- Do not generate hidden methods.
-u -- Python 1.5 and earlier: Do NOT convert all Unicode objects to
strings.
Python 1.6 and later: Convert all Unicode objects to strings.
-o -- Create output in a specified output file. If the path leading
to the file does not exist, any missing directories will be
created.
NOTE: -o cannot be used with -d. This will generate an error.
-d -- Generate the base code now and the class code on demand.
Recommended for large type libraries.
typelib -- A TLB, DLL, OCX or anything containing COM type information.
If a typelib is not specified, a window containing a textbox
will open from which you can select a registered type
library.
Examples:
makepy.py -d
Presents a list of registered type libraries from which you can make
a selection.
makepy.py -d "Microsoft Excel 8.0 Object Library"
Generate support for the type library with the specified description
(in this case, the MS Excel object model).
