The DrRacket Plug-in

• Open DrRacket

• Change the language to Racket:

  • Open the Language menu

  • Select "The Racket Language"

  • Click the Run button

  • The Interactions area should display:

    Welcome to DrRacket ...

    Language: racket; ....

• Enter the following program in the Definition area, then press Run:

  #lang racket

  (require pkg)

  (require setup/setup)

  (define links (find-system-path 'links-file))

  (when (file-exists? links)

  (delete-file links))

  (define pkgs (build-path (find-system-path 'pref-dir) "5.3.6" "pkgs"))

  (when (directory-exists? pkgs)

  (delete-directory/files pkgs))

• Restart DrRacket. Then install the .plt file using the instructions in Online Management.

If that does not install the plug-in, SEE A TA ASAP.
