This guide describes how to use Sugar Labs' Packaging Management System.

Installation

Required packages

At first, install PackageKit related packages. The following command will install two Polkit authentication agents, one for Gnome session (if you start sugar emulator from Gnome Desktop Environment) and LXPolkit that will be used from Sugar session.

Fedora specific instructions: 

sudo yum install gnome-packagekit lxpolkit

Debian and Ubuntu specific instructons (there is no official package for LXPolkit?): 

sudo apt-get install packagekit-gnome

Relogin from X session to let Gnome or Sugar start Polkit authentication agent.

Bundle install

wget http://download.sugarlabs.org/sweets/sweets/installer.sh
sh installer.sh

Relogin from X session to take into account new PATH environment variable value.

Sources install

This will be useful for people who prefer using sources.

  • Clone sweets sources and install it (after the first run, you need to relogin to take into account the new PATH value, then just run sweets command):
git clone --recursive git://git.sugarlabs.org/sdk/sweets.git
sweets/sweets upgrade

Note, it is important to use --recursive because git repository contains one submodule.

Upgrade

If sweets was installed from a bundle: 

sweets upgrade

If sweets is being used from sources, pull new commits from cloned directory: 

git --recurse-submodules pull origin master

Note, it is important to use --recurse-submodules because git repository contains one submodule.

Launch sugar

To launch sugar session: 

sweets sdk/sugar

or to run from Xephyr: 

sweets sdk/sugar:emulator

It is possible to run different glucose versions via sweets (for now, testing 0.92+ and stable 0.88 based on Dextrose-2), e.g.: 

sweets sdk/sugar:emulator=0.88

To get the full list of available versions: 

sweets show sdk/sugar -v

For launch command, all arguments passed after sweet name are treated as launched sweet's arguments. For example, it is possible to run sugar by bassing -f argument: 

sweets sdk/sugar:emulator=0.88 -f

If sweets can't find proper implementation, see the E lines in output of: 

sweets show sdk/sugar -vdd

Development workflow with sweets

During the first launch, sources will be auto-built and kept in internal storage. To make sweets useful for development, checkout developing project sources in sweets: 

sweets checkout [path-to-sources]

The only thing that is required from sources is having a sweets.recipe spec file for non-activity projects or activity/activity.info (that conforms to the same spec) for activities. All sweets for Glucose components are located in the http://git.sugarlabs.org/sdk project.

After being checked out, these sources might be launched using http://sweets.sugarlabs.org/sweet-value-from-sweets.recipe or just mentioning a sweet value: 

sweets sweet

For glucose projects, you can find ready-to-use and always-rebased-to-upstream projects in the SDK http://git.sugarlabs.org project. For now, there are two branches: master for recent trunk, and master-0.88 for 0.88 code based on Dextrose-2 patches.

Checked out projects will be built according to the [Build] section commands in the sweets.recipe files. In general, for autotools-based projects, there is no further need for the sweets command, just run make install to build current sources and make install them them to the directory that was specified by sweets in the configure stage. For glucose projects, there is no need even in calling the make command (python code will be reused from its original place, see binding options in sweets.recipe files), just change the code and restart sugar.

Run sweets from X session

Place sweets invocation into your ~/.xsession file: 

PATH=$HOME/.local/bin:$PATH
sweets sdk/sugar

and create a /usr/share/xsessions/sweets.desktop desktop file: 

[Desktop Entry]
Encoding=UTF-8
Name=Sweets
GenericName=Sweets
Exec=/etc/X11/Xsession
Type=Application

Current limitations

  • For now, sweets knowns only about the glucose dependencies to install them from native packages in Debian, Ubuntu, Fedora, Mandriva, openSUSE, and Gentoo.
  • Activities can't reuse sweets benefits.
