# 38.1. `gensuitemodule` — Generate OSA stub packages

The `gensuitemodule` module creates a Python package implementing stub code for the AppleScript suites that are implemented by a specific application, according to its AppleScript dictionary.

It is usually invoked by the user through the PythonIDE, but it can also be run as a script from the command line (pass `--help` for help on the options) or imported from Python code. For an example of its use see `Mac/scripts/genallsuites.py` in a source distribution, which generates the stub packages that are included in the standard library.

It defines the following public functions:

`gensuitemodule.``is_scriptable`(application)

  Returns true if `application`, which should be passed as a pathname, appears to be scriptable. Take the return value with a grain of salt: Internet Explorer appears not to be scriptable but definitely is.

`gensuitemodule.``processfile`(application[, output, basepkgname, edit_modnames, creatorsignature, dump, verbose])

  Create a stub package for `application`, which should be passed as a full pathname. For a `.app` bundle this is the pathname to the bundle, not to the executable inside the bundle; for an unbundled CFM application you pass the filename of the application binary.

  This function asks the application for its OSA terminology resources, decodes these resources and uses the resultant data to create the Python code for the package implementing the client stubs.

  `output` is the pathname where the resulting package is stored, if not specified a standard “save file as” dialog is presented to the user. `basepkgname` is the base package on which this package will build, and defaults to `StdSuites`. Only when generating `StdSuites` itself do you need to specify this. `edit_modnames` is a dictionary that can be used to change modulenames that are too ugly after name mangling. `creator_signature` can be used to override the 4-char creator code, which is normally obtained from the `PkgInfo` file in the package or from the CFM file creator signature. When `dump` is given it should refer to a file object, and `processfile` will stop after decoding the resources and dump the Python representation of the terminology resources to this file. `verbose` should also be a file object, and specifying it will cause `processfile` to tell you what it is doing.

`gensuitemodule.``processfile_fromresource`(application[, output, basepkgname, edit_modnames, creatorsignature, dump, verbose])

  This function does the same as `processfile`, except that it uses a different method to get the terminology resources. It opens `application` as a resource file and reads all `"aete"` and `"aeut"` resources from this file.
