    Turbo Vision based IDE for Turbo C++

    Turbo Vision is a character-mode text user interface framework included with Borland Pascal, Turbo Pascal, and Borland C++ circa 1990. It was used by Borland itself to write the integrated development environments (IDE) for these programming languages. By default, Turbo Vision applications replicate the look and feel of these IDEs, including edit controls, list boxes, check boxes, radio buttons and menus, all of which have built-in mouse support. Later it was deprecated in favor of Object Windows Library, the Win16 API, and the GUI tools of Borland Delphi.

    Around 1997, the C++ version, including source code, was released by Borland into the public domain[1][2]. Several developers and developer teams have worked on their own versions of the framework afterwards. Some of them have been listed in the table below.

    The Pascal version, which was distributed alongside Borland Pascal 7 on a "bonus" disk, was never released under a free software license, so the Free Pascal project recreated its own version by backporting a clone made by Leon de Boer that ran in graphical mode back to textmode. The result is called Free Vision.[3] Over the years this codebase has grown stable on nearly all operating systems and architectures that FPC supports. The textmode IDE is very close to the original TP environment, with built-in compiler and IDE much closer than e.g. RHIDE, and supporting functionality like code folding.

    Unicode support

    [edit | edit source]

    One of the factors limiting Turbo Vision's popularity was the absence of Unicode support in the original Borland version. As of October 2020, there are Unicode versions for C++[4] and Free Pascal.[5]

[...] According to a FAQ entry in the Borland's site (was in http://www.inprise.com/devsupport/bcppbuilder/faq/QNA906.html[permanent dead link] when I saw it) the code is public domain. I also asked in the Borland's newsgroup and the TeamB people (not official people but they are who give technical support in the net) said me the FAQ was right."
