Hi Pavel, thanks for giving this a try.

The only way for me to get that error is to set the NO_STREAMABLE macro definition at compile time. Could it be that you enabled it? For any particular reason? Or did you manipulate the nm*.cpp or s*.cpp files in source/tvision/?

Unfortunately, Turbo Vision does not support being built completely without streaming support. The library code is missing #if !defined(NO_STREAMABLE) guards in some places, but last time I tried to add them I got compilation errors.

The only reliable way to use NO_STREAMABLE at the moment is to define it only when compiling the applications. But since the CMakeLists.txt of this project is very badly written, you get the same compilation flags both when building the library and when building the applications.

I have fresh git repository. I didn't touch (or modify any file).

Just

cmake . make

/usr/bin/ar: CMakeFiles/tvision.dir/source/linux/ansidisp.cpp.o: plugin needed to handle lto object

Okay, it seems that the issue is LTO. Try removing -flto from CMakeLists.txt.

[okbob]

Now, it is working well. Thank you. Unfortunately UTF8 doesn't work, I tried display file with utf8 content, but any other is perfect

[okbob]

I remember I had to install libgpm-devel - it was not optional (it is maybe wrong in readme).

Missing UTF8 support is not related to this issue, so I close this issue. It is pretty fast and looks pretty well. Good work. Thank you for support.

[magiblot]

Thanks. What error did you get before installing libgpm-devel? It is intended to be optional. Maybe it found the library but the headers were not installed. I'll have to change the CMakeLists.txt.

Regarding UTF-8, there are two separate issues: 1) The Turbo Vision API doesn't allow multibyte I/O, although it would not be difficult to extend. 2) Turbo Vision widgets do not support multibyte or wide char encodings, e.g. pressing the Left key in an input form or editor moves the cursor one byte, not one character.

For simplicity, I left things as they were. The most difficult to fix is point 2. With unicode-aware widgets, it would be pretty easy to display and write unicode text with minimal API changes.

I am sorry, I was messy due to the last problem. I recheck compilation without libgpm-devel and it is working. I am sorry again.

1. The Turbo Vision API doesn't allow multibyte I/O, although it would not be difficult to extend.
2. Turbo Vision widgets do not support multibyte or wide char encodings, e.g. pressing the Left key in an input form or editor moves the cursor one byte, not one character.

yes, it can be lot of work.

Hi Pavel. In case you may be interested, I implemented Unicode support in Turbo Vision. It's documented in the project's Readme. I also wrote a small text editor which makes use of the Unicode capabilities of Turbo Vision.

Cheers.

[magiblot]

I checked tvedit and tvdemo - it shows unicode well, but it doesn't allow unicode chars

That's right. I am not sure adding Unicode support to TEditor is worth the effort. Tvedit should not be taken as a serious editor anyway--it has a single-step undo buffer (and no redo action) and lacks a lot of functionality. The only reason why anybody would use it is because of its vintage look-and-feel. In order to support Unicode in TEditor without severing performance, special data structures are necessary ("position caches" as named in Scintilla).

However, TEditor also provides functionality to TMemo, so its use cases go beyond Tvedit. That's the only reason I would add Unicode support eventually. But I do not intend to do that anytime soon.

On the other hand Tvdemo is very easy to fix. Unicode support there would be actually useful as example for other developers.

you can try to port new vim or emacs to tvision :) - it can be a super bomb to have these editors with user friendly and nice UI.

More seriously - probably integration of neovim should not be too hard.

I have also thought of that -- in addition, by making a clone of vim, I would probably learn the vim commands at last.

But I am not sure about the usability part: there already exist GUI applications for these editors--how could a TUI be any more user friendly than that?

Other people have talked about making a clone of VS Code--all these are good ideas. But it takes a lot of time. Personally I feel like I have already spent enough time on Turbo Vision and the Turbo editor. The tools are out there in case anybody wants to undertake these tasks.

The TUI for emacs is pretty ugly - there is no TUI with a good look.

I understand it well. It was a little bit of a joke from me, but if you design editor based on scintilla, then maybe you can use neovim - it is similar to the editor framework, but it is much more popular I think. On second hand, I understand very well how much time it takes, and how much time needs a change of some basic component.
