Help me find the bug in my terminal-based editor

[Amirouche Boubekki]

Hello,


I have a strange bug in my terminal-based editor.
The code can be found at https://framagit.org/a-guile-mind/zk

To install you will need guile-bytestructures and guile-pfds.

Then:

  git clone https://framagit.org/a-guile-mind/zk
  cd zk
  make dev

You will also need to change the following line:

  https://framagit.org/a-guile-mind/zk/blob/master/zk/termbox.scm#L174

Then you can type:

  make run

This will clear the terminal and display the content of 'zk.scm'.

If you type 'enter' key, it should add a newline at the start
of the buffer. It does, but rendering has glitches. If you resize
the window it will remove the glitches.

FWIW, here is the previous iteration that works but doesn't support
multiple buffers and frames: https://github.com/a-guile-mind/azul.scm


Can someone help?
