The sense of nostalgia this evokes is so strong, thank you for sharing this!

It's awesome. Free Pascal IDE is based on this I think. It certainly something to aspire to :) thanks for sharing

  It isn't, Free Vision (Free Pascal's own Turbo Vision library) has a much more weird history though it is indirectly based on the C++ code Borland released back in the 90s, like the version linked here (see my other comment). They have a common ancestor but they are different "branches".

    I see, thanks for the clarification. Btw, I really enjoyed YT "Making a game in Free Pascal" back in the day. I did learn a lot from your video :) Pascal is one of my top languages to code in! Nice to see you around here

      You just made me realize it has been 10 years since that video :-P. It has been a while since i made a similar video (last one was 'Making a game in Linux using Lazarus' from 6 years ago, most of my more recent videos are random clips from random stuff i work on). Perhaps i'll try making a new one at some point. [0] https://www.youtube.com/watch?v=s_01Xhd2EJM https://www.youtube.com/watch?v=s_01Xhd2EJM

that's cool! so this is the turbo-* vision part, but the *-pascal part is not included? is there one of those anybody knows about? I have the source to a turbo pascal BRIDGE.PAS card game player I used to enjoy playing. (it's not a good bridge player and it has a scoring bug, but I know how to fix it, and I can run it in dosbox if I want so I'm not desperate in that sense, but I'd rather run native)

  Free Pascal comes with Free Vision. FV has some weird history in that Borland released their C++ conversion of Turbo Vision to public domain, then someone converted that to Turbo Pascal and converted it to use graphics instead of textmode (with coordinates in pixels, etc) and then it was ported to Free Pascal and converted back to text mode and to use Free Pascal's cross platform text mode units. The Free Pascal IDE that comes with the compiler is made using Free Vision and Free Vision works on pretty much any platform Free Pascal itself supports (as long as it has some form of text mode). Regardless of the history, the API is basically the same, you can even read a tutorial written for Turbo Vision and apply it to Free Pascal with minimal changes. Recently there has been a UTF-8 version (original TP -and FV- was made for 8bit DOS character codes) though it is a big buggy and slower than the non-UTF-8 version. I tried to use to make an Info viewer[0] some months ago but i had to switch to the non-UTF-8 version due to the bugs. [0] https://i.imgur.com/Qvkt3W0.png https://i.imgur.com/Qvkt3W0.png
