9.4 API for Installing ".plt" Archives

The setup/plt-single-installer module provides a function for installing a single ".plt" file, and setup/plt-installer wraps it with a GUI interface.

9.4.1 Non-GUI Installer

 (require setup/plt-single-installer)

procedure

(run-single-installer file get-dir-proc)  void?

  file : path-string?
  get-dir-proc : (-> (or/c path-string? false/c))
Creates a separate thread and namespace, runs the installer in that thread with the new namespace, and returns when the thread completes or dies. It also creates a custodian (see Custodians) to manage the created thread, sets the exit handler for the thread to shut down the custodian, and explicitly shuts down the custodian when the created thread terminates or dies.

The get-dir-proc procedure is called if the installer needs a target directory for installation, and a #f result means that the user canceled the installation. Typically, get-dir-proc is current-directory. v

procedure

(install-planet-package file directory spec)  void?

  file : path-string?
  directory : path-string?
  spec : 
(list/c string? string?
        (listof string?)
        exact-nonnegative-integer?
        exact-nonnegative-integer?)
Similar to run-single-installer, but runs the setup process to install the archive file into directory as the PLaneT package described by spec. The user-specific documentation index is not rebuilt, so reindex-user-documentation should be run after a set of PLaneT packages are installed.

Similar to run-single-installer, but runs only the part of the setup process that rebuilds the user-specific documentation start page, search page, and master index.

procedure

(clean-planet-package directory spec)  void?

  directory : path-string?
  spec : 
(list/c string? string?
        (listof string?)
        exact-nonnegative-integer?
        exact-nonnegative-integer?)
Undoes the work of install-planet-package. The user-specific documentation index is not rebuilt, so reindex-user-documentation should be run after a set of PLaneT packages are removed.

9.4.2 GUI 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)
Creates a frame, sets up the current error and output ports, and turns on the busy cursor before calling do-install in a separate thread.

Returns before the installation process is complete; cleanup-thunk is called on a queued callback to the eventspace active when with-installer-window is invoked.

procedure

(run-single-installer file get-dir-proc)  void?

  file : path-string?
  get-dir-proc : (-> (or/c path-string? false/c))
The same as the export from setup/plt-single-installer, but with a GUI.

9.4.3 GUI Unpacking Signature

signature

setup:plt-installer^ : signature

Provides two names: run-installer and on-installer-run.

9.4.4 GUI Unpacking Unit

Imports mred^ and exports setup:plt-installer^.
