So many YouTube videos start out Before we begin click the like button click subscribe and click notifications. In other words just assume this video is great before you find out what a steaming pile of crap it really is. Maybe you’ll forget to undo everything once you figure it out.

I’ve been looking for a good example of doing this non GUI in Free Pascal. Read some tips but nothing came together. So I found this example that works. So full credit to Mr Bee pakLebah. It does use the Lazarus IDE, I think because it uses some Lazarus components…but not objects but it creates …

sudo zypper install python38-jupyter-core. Tried pip3 install first but afterwords it couldn’t find Jupyter.

Decided to look into this, so I joined Julia Computing. They recommend I install JuliaPro. Of course now I need to join JuliaPro. I’m already a member of Julia Discourse. Anyway Julia Pro is about 3 times bigger than the latest version of Julia. OK have to abandon install on OpenSuse because not in prerequisites. …

I can’t quite nail it down but weird things happen to your Lazarus files. I open a project and don’t save. Then I create or open another project and it pulls in stuff from the last place I was at. Same with saving, things aren’t necessarily saved in the project directory you think you’re in.

Success!

Anywho I successfully compiled and ran a simple SQLite program. Returning values in a data grid, Visually it looks like this Behind the scenes Lazarus creates …

Still seeing the controls on the form and basically recreating them got me somewhere

Double clicking on a new Lazarus .lpi file, does open the code and form. As noted it wasn’t working on older .lpi projects. Something strange is happening though. After getting things working, I’m unaware of making any other changes. But perhaps look at another project…once again not making any changes or saving that I’m aware …

I remember learning Pascal (Free Pascal) and Lazarus soon after. First attempts was in 2003. I remember writing a decent name parsing (Prefix, First, Middle, Last, Suffix) routine in Free Pascal.
