GUI ".plt" Installer

The setup/plt-installer library in the setup collection defines procedures for installing a ".plt" archive with a GUI (using the facilities of racket/gui/base).

procedure

(run-installer filename)  void?

  filename : path-string?
Run the installer on the ".plt" file in filename and show the output in a window. This is a composition of with-installer-window and run-single-installer with a get-dir-proc that prompts the user for a directory (turning off the busy cursor while the dialog is active).

parameter

(on-installer-run)  (-> any)

(on-installer-run thunk)  void?
  thunk : (-> any)
A thunk that is run after a ".plt" file is installed.

procedure

(with-installer-window do-install    
  cleanup-thunk)  void?
  do-install : 
(-> (or/c (is-a?/c dialog%) (is-a?/c frame%))
    void?)
  cleanup-thunk : (-> any)
Equivalent to
(define installer-run (on-installer-run))
(parameterize ([on-terminal-run
                (λ ()
                  (printf "\nInstallation complete.\n")
                  (installer-run))])
  (in-terminal
   (λ (custodian tlw) (do-install tlw))
   #:title (string-constant plt-installer-progress-window-title)
   #:cleanup-thunk cleanup-thunk))

procedure

(run-single-installer 
  file 
  get-dir-proc 
  [#:show-beginning-of-file? show-beginning-of-file?]) 
  void?
  file : path-string?
  get-dir-proc : (-> (or/c path-string? #f))
  show-beginning-of-file? : any/c = #f
The same as the export from setup/plt-single-installer, but with a GUI.
