A great place to learn and have fun with computers. LazPlanet is a place for Lazarus and Freepascal sample source codes, articles and tutorials. To install a newer version of Free Pascal, I later followed the steps on the wiki and downloaded the laz and src. This put the source code under /usr/share/fpcsrc/3.0.4 and my lazbuild file under /usr/bin. Rewriting generate.py in Pascal would be a fool's errand. 2 Projects using the Lazarus Component Library (LCL) 3 Projects using the fpGUI graphical user interface. In this article, we are going to create a fun, simple video player. In my case, I installed Free Pascal with Lazarus by running apt-get install lazarus on my Ubuntu WSL. When you choose File | New | qooxdoo Javascript App, the Pascal package runs the qooxdoo generate.py script to create the app skeleton. That's easy to do and is already done in at least one package for Lazarus: the name of a structured variable, that could have named members, i.

For example, QGIS includes Python in its Windows installer since Python is required for its many plugins (and Python is not installed on Windows by default the way it is on Mac and Linux).ĭo you have Python skills such that you prefer to write most of the code in Python? If so, I wouldn't bother with Pascal.Īgain, what is _essential_ about what you've proposed (Pascal GUI calling Python code) that forces you down this route? What problem are you trying to solve? I don't have a clue as to what you're thinking of doing.ĭo you have a large existing Python codebase and you need to embed the Python interpreter into a GUI (Pascal) desktop app? See references above. If you are feeling brave enough you can try implementing the graphics part in fpgui, which doesn't have all the baggage of the LCL but has fewer controls implemented. You will also need some more info into the Lazarus RTTI and developments in the RTTI branch will help. Modern Pascal can do whatever every other languages out there are able to do. I've been making many apps for all platforms using (mainly) Free Pascal, with Lazarus IDE (for GUI apps) and VS Code (for non-GUI apps). Given that the developer of VCLua managed to wrap it all into a DLL and make the whole thing accessible directly from the command line without any hint of Lazarus involved, I think that is your best bet, or at least your guide to insight into the process. What I meant by Pascal is the modern object Pascal programming, not your daddy's Pascal. On the Python level there is which has had some FPC related updates at and It has an English like syntax making the language easy to learn. Pascal is an excellent teaching or learning language. The tutorials start with the basics and get more advanced. Free Pascal and Lazarus is a Delphi like language and IDE. You can do it, but it requires good knowledge of the language as well as Lazarus/FreePascal.Ī good example of what you are thinking of is VCL Lua.Īnother one is pLua - which has gone into developing which is a Delphi project.įor simpler starting libraries that give more insight into the process there is stuff like, which give some insight into how Lua links with Lazarus. The Free Pascal Compiler and Lazarus works on Windows, Mac and Linux. It is a combined Client Side Run Time Library and RAD IDE intended to allow Pascal (Pas2JS) and/or Python (Pyodide) development with the minimum of installation or learning curve while also. Warren Hill on How to create forms at run tim… XIDE is a simple, stand alone, open source IDE for Free Pascal which runs in the browser (and on other platforms supported by Lazarus).
