Can I also mention https://bugs.freepascal.org/view.php?id=18248 please and the VHDL and Verilog highlighters in the final note?
1) Download and compile.2) Run some test data.- I wouldn't worry about registering them in the component palette. Create them from code.- Set colors, if needed- Put text in the editor, and see if the HL does something at all.2a) Edit the text data. Undo/Redo....3) Debugging, if needed...Depends on each HL, but to know what SynEdit might call: https://wiki.lazarus.freepascal.org/SynEdit_HighlighterIf they are that old, they probably need at least be changed to the correct base class
Are you saying they can be compiled in isolation, without being installed as packages?I've really done /very/ little with packages, even as a user.
