## GUI ".plt" Installer🔗ℹ

(require setup/plt-installer) | package: drracket

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.
