New to Pharo: Some questions
Hello, I hope everyone is doing well. I am new to Pharo but not to programming. I have a background in Python, and Javascript mostly. I mostly use Python due to the data, plotting, and math libraries. But after toying a little with Pharo, the language I came to appreciate its beauty of it and how expressive the language is. I was wondering if there are libraries equivalent to Matplotlib, Pandas, Numpy, etc. I mostly apply Python to finance -in particular to quantitative finance. I read somewhere that top investment banks use Smalltalk as their secret weapon, so I'm sure that there are some users that have some insights to share on this subject. Thanks to all and all the best for this 2023. Greetings Juan P. Cruz
This may seem a little over simplistic, but the basics of what NumPy and Pandas offer can be achieved with the standard Smalltalk collection hierarchy. If your data fits in memory, then Pharo will handle the job. If not, then GemStone may do the trick. That said, thereâs a bunch of quite specialised stuff in those libraries, some of which is not trivial to implement. Or you may have gigantic existing datasets that you want to leverage. So you can always call the python libraries directly from Smalltalk using the PythonBridge [1]. Itâs been a long time since Iâve used it, so hopefully someone else can let you know if itâs still well maintained. There are a bunch of options for plotting. Maybe start by checking out Roassal [2]. You may even want to check out Glamorous Toolkit [3]. It may change your life ;) [1] https://objectprofile.github.io/PythonBridge/ [2] http://agilevisualization.com <http://agilevisualization.com/> [3] https://gtoolkit.com <https://gtoolkit.com/>

Hi, Thanks for your response. The size of datasets is not an issue, but my intention is not to bridge to Python. The reason behind the question is that (and sorry for those who love it) I think Python is an ugly language. It's very powerful due to its libraries: Yes. But as a language, I find it ugly and not very expressive. Besides, the fact that indentation has syntax meaning is really annoying. I tried Haskell, beautiful. Also Closure and Ruby. Love those. But Smalltalk caught my attention as I read in different sources that it was actively used in the financial industry, so I figure out that there were some advanced libraries out there...Probably they exist and are proprietary or secret haha. Thanks so much I will keep toying with Pharo, these days have been really fun. It is really fun to code in Pharo...and easy!! No need to set up environments, select editors, plugins, or debuggers..it´s all there! Have a great Sunday Juan P.

Hi Juan, you might have a look to PolyMath: https://github.com/PolyMathOrg/PolyMath We are trying to build something equivalent to pandas et other scientific libraries in Python. Arms to help us are welcome ;-) Regards, On Mon, 16 Jan 2023 at 04:10, Juan Cruz <juan.crux@outlook.com> wrote:

Hola Juan, Good to hear that you are interested in Pharo. The equivalent of Matplotlib is Roassal. You can check this video that we did (7min) of using Roassal for making visualizations for football data: [ https://www.youtube.com/watch?v=LOn9jVGa83c | https://www.youtube.com/watch?v=LOn9jVGa83c ] :) For data mining we have some algorithms in pharo-ai [ https://github.com/pharo-ai/wiki | https://github.com/pharo-ai/wiki ] (wiki not updated at 100%) we also have some other machine learning stuffs. And we also have PolyMath : [ https://github.com/PolyMathOrg/PolyMath | https://github.com/PolyMathOrg/PolyMath ] for scientific computations :) Regards, Sebastian Jordan

Thanks, Sebastian for pointing to these libraries. For sure I will take a look at them! Best, Juan P.
