Dear Julia users, I am using an optimization model which is written in Delphi/Pascal and is called from a Python-Skript. However, Delphi (in my opinion) is not a very user friendly language and I would like to switch to a more modern open-source language. Python is too slow for my use case, but as …

I am as usual going to say something stupid here. It looks like this code has been given to you, or you have taken over a project? Maybe take a step back and ask what this optimization model is supposed to do. Maybe there is a clean and easy way to write a model like that in Julia, with an existin…

Well, probably you won’t need more then 2000 LOC in Julia for the same task, but that requires to rethink what the model is supposed to do…

thank you already for you’re replies! The code is part of a project that I joined. So on the one hand, it was given to me, on the other hand it is still used by other people in my group. The model is an energy system model - so basically the function that get’s optimized. For the optimizer itself I…

I was thinking about something like that. But do you know if there is something similar like PyCall to call Delphi from Julia? Can you do something like that with CCall?

We had an old reactor model in Delphi. Rewrote into Julia. Speed-up 100x and much more maintainable. The only downside is not being able to easily compile to a DLL, but there are workarounds.

You can create dlls with delphi that can be called from C, and if they can be called from C then they can also be called from Julia. Not much documentation on how to do it available. Example for calling Delphi dlls from R: https://snoweye.github.io/R_note/inc_menu/reference/dfu/delphi_dlls_for_R.h…

@ufechner7 Delphi is one of the most productive languages. According to a study performed in 2017 by Namcook Analytics LLC, Delphi is in position 5 in the Function Point index, seriously outperforming its main competitor (C and C++). Julia is two positions under Delphi. But that considering that t…

Why do you think Delphi is not modern? In the last 5 years, Delphi had 7 major releases. Compare that with Julia’s releases. Also, why would you call Delphi “not modern” when it can do GUIs nativelly since 1994? Isn’t Julia the one that cannot do natively GUIs? (Never empty words, without citation…

This thread just popped at in my account again so I wanted to use that opportunity to thank the community for your remarks and advises :slight_smile: We finally switched our model from Delphi to julia and it fulfilled our expectations. I indeed ended up translating the code and using the old model t…
