Good. Really nice to see more bridges between Pharo and the external world and playing well with other programming languages, frameworks and documentation systems.

Hello,

My new year main resolution: stop keeping my side-projects for me.

It��s been like 1 year that I created these two projects, one coming from a refactoring of the other.

Now it is time to take time to announce them.

I initially come from Python world and during my bachelor & master, I really liked to use matplotlib to plot data using Python.

So I wanted to be able to use this Python module from Pharo. I did it by generating Python 3 code from Pharo and making Python 3 executing it. So, first I implemented everything in MatplotLibBridge package and then I split it in two package in order to be able to eventually create bridges to other Python 3 modules.

So, Python3Generator [1] is made for generating programatically Python 3 code from Pharo. Basically, it allows you to easily build a Python 3 AST, ��to serialize it in Python 3 source code and eventually to execute it. For now you can transfer data from Pharo to Python (e.g. providing arguments to functions that are Pharo��s objects) but you can not retrieve data stored in Python variable from Pharo (but it should be possible, just I don��t need to do that for my bridge to matplotlib). Some examples are provided on the github��s README.

MatplotLibBridge [2] is made for creating plots using matplotlib [3] from Pharo. There is a bunch of examples of what you can do on the README. The two features from matplotlib I like the most are: 1. You can generate your plot in a lot of file formats (png, pdf, svg, ps, etc��) 2. It allows to embed LaTeX mathematical formulae everywhere in the plot (which can be really cool). All the possible plots in matplotlib are not available in Pharo��s side because I build parts of the bridge when I need them but it is not hard to do. I someone is interested in a plot type not available yet, please tell me.

So, it is announced, if someone want to do something with those, please do it!

Happy new year.

Regards,

Julien
