As someone who used to develop in Delphi for my day job, but has been mostly out of the loop for the last ~10 years, this really got me curious: do people actually use VSCode for Delphi? I mean, Delphi already comes with an IDE, including a GUI ("Forms") designer - that was its killer feature back in the nineties, that you could slap together a GUI app as quickly as in good ol' Visual Basic, but backed by a compiled language. Maybe the text editor is better in VSCode, but still I imagine it's pretty hard to deliver the same experience as with the "native" Delphi IDE? So I can understand that JetBrains doesn't see a huge market for that (unless they could become the official Delphi IDE, like they did with Android Studio).
I have current Delphi project with heavy GUI. I'd be out of my mind to use VS Code for it. I use VS code for scripting stuff where it more or less shines (JS, Bash scripts etc). Same for C++ - Visual Studio/QT Creator and CLion fill my needs way better than VS Code can ever do.
No clue, I just picked a random not super mainstream language as an example.
I'm sure vscode is terrible for Delphi, but I'm willing to bet that the experience (with whatever third party plugins exist) will be better than any jetbrains product.
