Embarcadero insane pricing of Delphi is the reason I haven't continued beyond my old version Xe2. I guess they are making hay while the sun shines with the locked-in customers.
In these days, Lazarus and FPC are a valid choice instead of Delphi, except when you are doing some heavy component based codes, like organization oriented projects. Plus side is Lazarus can produce a project and UI for almost any OS.
Do they have the yellow-on-blue syntax highlighting trademarked or something? I've looked for vim and vscode color schemes to match the original turbo c++ but to no avail. I remember borland builder had a setting to switch back to it.
That's a nice color scheme, but what really made those text-mode IDE's intuitive was the TUI widgets and support for multiple views. Probably easier to do in neovim than plain old vi/vim of course. With modern devtooling support as found in neovim you could also have inline help, which was also very useful in those older environments.
