Glamorous Toolkit offers Python interoperability functionality. It allows mixing Python and Smalltalk more-or-less seamlessly in a Lepiter playground. How does that work? Brace yourselves, it’s boutta get ugly.
The main entry point, from the Smalltalk side, into the integration is PBApplication
. There are multiple references to PBApplication start
as the way to get it going. PBApplication
is a part of PythonBridge, forked by Feenk. PythonBridge is based on the general “LanguageLink” abstraction from PharoLink. In any case, through various abstractions, it uses pipenv to create a virtual environment in the PythonBridgeRuntime
subdirectory of the Glamorous Toolkit installation directory. Into this virtual environment, the gtoolkit_bridge
package is installed (source in PyPI
directory of Feenk’s PythonBridge
fork).
The LanguageLink abstraction and gtoolkit_bridge
have a protocol for exchanging messages. It can go over one of two transports:
