rackedit

rackedit opens a simple Racket editor window for a file. It can be used from DrRacket, from a Racket program, or from the Racket command line.

The package exports one procedure:

(require rackedit)

(rkdt "notes.rkt")

By default rkdt shows the editor and returns immediately. Use #:wait? #t when execution should continue only after the editor is closed:

(rkdt "notes.rkt" #:wait? #t)

The initial window geometry can be specified with #:width, #:height, #:x, and #:y. Window positions and sizes are remembered per internal editor number and per screen configuration.

The frame can be observed or customized with #:frame-cb. The callback receives an event symbol and the editor frame. It is called at the lifecycle points 'before-show, 'after-show, 'wait-for-close, and 'on-close. 'wait-for-close is emitted only when #:wait? #t is used.

For example, the window title can be changed before the frame becomes visible:

(require racket/class
         rackedit)

(rkdt "notes.rkt"
      #:frame-cb
      (λ (event frame)
        (when (eq? event 'before-show)
          (send frame set-label "Notes"))))

The standard File menu does not contain the Exit/Quit command, so closing one editor window does not imply exiting the application that opened it.
