Ask AL: pprint + vim
1 point by antiismist 5862 days ago | 8 comments
Anyone figure out how to use pprint.arc from within VIM? I'm trying to highlight some text in VIM, and execute a command to get it replaced with pretty printed code. Haven't quite got it figured out yet. Thanks!

It should be possible, in theory, to create a wrapper script that executes the arc code, but the problems are:

1. Arc-on-mzscheme startup time is slow

2. Arc-on-mzscheme doesn't support properly launching from any directory other than the installation directory.

If the above problems are fixed (or if problem 2 is fixed and you don't find problem 1 too much of a problem) we could simply use shift-V, select range, then shift-1 and type the script name.

Is there any way to shoot the text over to an already running interpreter and capture the output (to delay startup times..)?

Possibly some mkfifo hackery in Linux?

Possibly do something stupid like:

  mkfifo to_arc
  mkfifo from_arc
  ./ < to_arc > from_arc
Then just pipe commands through the to_arc and from_arc FIFO's? (this is untested)

Edit: Alternatively, you might want to do this in a thread on an existing arc session, again still using mkfifo hackery:

  (w/infile i "to_arc"
    (w/outfile o "from_arc"
      (w/uniq invalid
        (def foo ()
          (let ip (read i invalid)
            (if (isnt ip invalid)
                (write (eval ip) o)))
  (thread (foo))

ESC :q


Oh so entertaining to see AL get questions directed to him in the same style as PG.

PG must be getting married. He's been gone long enough for someone to take over leadership of these forums.

AL was supposed to be Arc Language, but good point on almkglor too.

Not the first time:

Congrats to him on becoming mini-leader of Arc!
