For core addons (those downloadable directly from Jsoftware) and the base library, there is a Jqt GUI interface called Package Manager and a console interface using the jpkg verb.

Other addons can be installed from github using the install verb.

In each case you need internet access as well as write access to the ~addons folder. No personal data is sent to Jsoftware or github.

Package Manager

In Jqt, select menu Tools|Package Manager. This lists the installed and available packages for selection and installation.

jpkg Verb

This is a console interface for Package Manager. First load the package manager:

load 'pacman'

Then the jpkg verb is available with syntax:

<option> jpkg <addon name(s)>

where <option> is one of the following :

  • 'help' - display list of valid options for jpkg
  • 'history' - display the changelog for specified installed addon if present
  • 'install' - install specified addons if not installed locally, upgrades them to latest version if already installed
  • 'manifest - show manifest for specified installed addon
  • 'reinstall- shortcut for using the remove then install options
  • 'remove' - remove specified installed addon(s)
  • 'search' - display list of addons that contain the any of the "words" specified as the right argument
  • 'show' - display summary of addon(s) specified in the right argument
  • 'showinstalled' - display list of all installed addons
  • 'shownotinstalled' - display list of all addons not yet installed
  • 'showupgrade' - display list of all installed addons with later versions available
  • 'status' - display addon and base library status.
  • 'update' - update local copy of addon information from the server
  • 'upgrade' - upgrade specified installed addon(s) if later version is available

<addon name(s)> is one of the following:

  • the keyword 'all' which represents all packages.
  • space-delimited list of addon names
  • list of boxed addon names
  • zero length literal list - if specified with 'upgrade', all installed addons with later versions available will be upgraded.

For example:

   'update' jpkg ''         NB. updates local version of catalog
Updating server catalog...

install Verb

This facility was first available in J807, base library 8.7.15, and applies to github addons and commits whose manifest.ijs contains a FOLDER definition.

This will install an addon directly from github, and is primarily intended for non-core addons. The syntax is:

install 'github:owner/repo[@commit]'

The commit defaults to master.

For example:

installed: jsoftware/games_2048 master into folder: games/2048
installed: jsoftware/games_2048 9708e8a into folder: games/2048
   install 'github:cdburke/convert_pjson'
installed: cdburke/convert_pjson master into folder: convert/pjson
