Great, thanks for putting it on github so we can read through the code! Are there instructions for building and running in VirtualBox? Edit: found the instructions

  Can you add a link to the instructions?

  Yeah it is the same project, it was renamed to avoid clash with another unrelated project.

I just tried it under VirtualBox. You rock! :-) The file browser, editor, repl combination seems to work nicely. If I had one wish for an improvement: auto-indent, etc. in the editor. Amazing effort!! edit: one minor problem: the " and @ characters are reversed on my MacBook Air keyboard using VirtualBox 4.3.20.

  That's because it's expecting a UK keyboard layout. Press Alt-F12 to toggle to US, then it should work.

    That fixed it - thanks.

  A hint from how the Lisp Machine did quick auto-indent etc: it used doubly linked lines (each line had a link to the one above and below), and each included in its metadata a number for how much it changed the indentation. Maybe not necessary as fast as machines are today, but I found it pretty neat when I used the idea to make Goldhill Common Lisp's Emacs (an interpreter that ran on original formula IBM-PCs at the time) flash the opening paren that matched the one at the cursor (I think auto-indent was already there, but slow).

I tried to remember my username and password here for a good ten minutes so that I can congratulate you. This is amazing!

This is really really impressive! The code seems exceptionally well written at a first glance. Thank you! How much of ANSI Common Lisp does it implement?

Is anyone else able to move windows? I can open things by clicking, but windows won't drag. Still, very very cool little example.
- asynchrony 12y ago
  The readme mentions that windows are draggable by holding alt.
