Overview

This page serves as roadmap for the Slicer Automatic Update and Installation framework.

Use cases:

  • New Slicer version installed locally should be updated with the list of extensions previously installed.
  • Self update of Slicer

Terminology

  • User Interface
    • Extensions Manager is a Slicer dialog allowing the user to Search, Install, Remove and disable extensions.
    • ExtensionWizard module: This is a Slicer module providing a graphical interface within Slicer to aid in the creation of Slicer extensions.



Convention

Tasks listed in this page can be associated with any of these state:

  • ToBeDone
  • Check.svg Completed
  • In progress

Use case: Keep track of the installed extensions across version

The goal here is to simplify the number of steps allowing people to reinstall extensions that were used in a previous installation.

Current Process

  • Dennis added a third tab in the extension manager, using Qt Designer
  • extensionsInstallPath() returns platform-specific path to "NA-MIC" folder which has "Extensions-2456" subfolders for all installed Slicer versions
    • on Linux, that's in ~/.config/NA-MIC
    • on Windows, in AppData/Roaming
    • on OS X, seems to be a subdirectory of the application bundle
  • Dennis' idea: look for all Extensions-* subfolders – how to do that on OS X properly?
    • just found [Extensions]/InstallPath setting in .ini files -> by parsing all ini files, that could work cross-platform
    • on OS X, the inis are in ~/.config//www.na-mic.org
  • Dennis' plan was to use Python scripting, but using C++/Qt would also be a good option

Proposed Changes

  • a new (third) tab in the extension manager, which should list all previously installed extensions
  • view should have columns:
    • extension name
    • Slicer revisions / last revision in which the extension was installed
    • checkbox for batch installation, pre-checked from latest previous Slicer revision
    • rows with installed extensions could be grayed out
  • below that, a button for installing the checked extensions

Progress

  • Extract list of extensions installed. Look at npm for the format. ToBeDone
  • Extension manager:
    • Update ExtensionManageModel API so that "list" can be processed ToBeDone
    • Update entry "Install Extension from file" to "Install Extensions from file" and support "tar.gz", ".json" ToBeDone

Meta issue:

  • 2779: Mechanism to keep track of the installed extensions across version ToBeDone

Completed

NA

Use case: Self update of Slicer

Proposed Changes

  • Display list of nightly builds in a web view
  • Selecting a new version should automate:
    • download
    • auto-start installer, with extra information for the next steps
    • auto-start new Slicer
    • possibly, directly going to the above extensions-reinstallation tab (maybe not even showing the main window before)
  • stuff that is there, or might be useful
    • cross-platform re-start functionality is there (as part of extension installation)
    • probably, at least on Win/Linux, "start Slicer after installation" is possible
    • unattended installation on any platform(s)?
