I agree with brnt, while Delphi/Object Pascal seem to be quite popular according to the Tiobe Index, https://www.tiobe.com/tiobe-index/delphi-object-pascal/, I find it hard to find open-source projects when comparing it with other programming langs. Example:
* Delphi Programmers do not like to showcase or open-source their projects?
* Delphi/Pascal is used to create mainly proprietary software?
Either way, I think that for Free Pascal to prosper in the long term, something should change. Perhaps more open source projects published on Github/Gitlab.
FreePascal/Delphi are used by large number of developers. I do not think there is a need for them to prosper in a sense of high Tiobe index. There are way more obscure languages some pretty big companies are using for their internal stuff without much ado about popularity.
You are confusing "hard to find" with "less". There is way less projects on github (the original question specifically mentioned github). However 9,000 is still a big number and one can find virtually anything needed from a practical standpoint. On top of that both delphi and lazarus come with huge system libraries.
C++ for example dwarfs delphi on github. However when I am doing C++ I am looking for very few projects in very specific areas (network, file management, db connectivity etc). Suddenly your choice becomes not that big when you separate all the noise.
Also whole bunch of delphi projects are located elsewhere due to various reasons. Hence my advice to ask Google.
Finally delphi projects tend to be rather large and high quality, check this one for example: https://github.com/BeRo1985/pasvulkan or other repos from the same guy.
