Bridge that allows executing arbitrary pieces of Python code directly from Pharo.

The official webpage and documentation is https://objectprofile.github.io/PythonBridge/.

This project depends on Python3.6 (or Python3.7) and Pipenv.

To install Python3.6 follow the instructions on the Python webpage https://www.python.org/downloads/release/python-368/. To verify if you have Python3.6 just run in a terminal python3.6 --version, it should print something like Python 3.6.4.

To install Pipenv just use the following Pip instruction pip install pipenv, though depending on your python installation you may need to call it with sudo. If the command pip is not found, use pip3 instead. To verify if you have pipenv just run in a terminal pipenv --version, it should print something like pipenv, version 2018.11.26. We strongly suggest you to upgrade your pipenv version if it is older that 2018.11.26, because it has important bugfixes and performance improvements. To upgrade it just run sudo pip install pipenv --upgrade.

To install PythonBridge on Pharo just run the following script in a Pharo Playground:

Metacello new
    baseline: 'PythonBridge';
    repository: 'github://ObjectProfile/PythonBridge/src';
    load.
(Smalltalk at: #PBApplication) installPipenvEnvironment

The first part of the script is responsible of downloading the PythonBridge code and loading it in the image. The second part of the script is responsible of creating a pipenv environment for isolating the python libraries used by the bridge.

Depending on the internet connection, the script could take a couple of minutes to run.

Evaluating the following code in a playground should return 3:

PBApplication do: [ 
	PBCF << (P3GBinaryOperator new
						left: 1;
						right: 2;
						operator: $+;
						yourself).
	PBCF send waitForValue
	 ]

• You cannot have two images running at the same time with an open connection to Python. In the future, we will be able to manually set the port.
