Re: libapl with fpc (free pascal)

[Dr . Jürgen Sauermann]

    Hi,
      
      good to hear that init_libapl
    solved most of your problems.
    Regarding ∇: it is the same story as for )COPY.
    
    You could think of the apl interpreter binary as being
    libapl with an interactive stdio fontend:
    
        ╔═══ apl interpreter ═══╗
          ║                       ║
          ║ ┌── stdio ──────────┐ ║
          ║ │                   │ ║
          ║ │ cin / cout / cerr │ ║
          ║ └───────────────────┘ ║
          ║                       ║
          ║ ┌── libapl ─────────┐ ║
          ║ │                   │ ║
          ║ └───────────────────┘ ║
          ╚═══════════════════════╝
    
    Using libapl with other languages like python or erlang
    simply
    replaces the stdio frontend with the other language. The
    interpreter
    reads line by line from the frontend and processes it (aka. REPL).
    
    The ∇-editor uses, in principle, the same interface to the frontend,
    but it may pull a line rather than a line being pushed into it. I
    dont
    quite remember the details since this works for a long time now. But
    I believe the ∇-editor may have its own REPL loop.
    
    I should also mention some callbacks that you may set. Elias
    Mårtenson has written a GNU emacs integration for GNU many
    years ago, maybe you want to have a look at it as well.
    
    Best Regards,
    Jürgen
