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

Requirements

Install PackageKit and PackageKit authentication agent from native packages. On Debian-based systems, these packages are packagekit and packagekit-gnome (for Gnome Desktop Environment). For Fedora, PackageKit and gnome-packagekit.

PackageKit authentication agent should be launched to let the sweets command install dependencies. Usually it is started after being logged into a Desktop Environment session (it isn't for Sugar session).

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

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

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

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.

-== Installation ==
+== Requirements ==
-=== Required packages ===
+* Install PackageKit and PackageKit authentication agent from native packages. On Debian-based systems, these packages are {{Code|packagekit}} and {{Code|packagekit-gnome}} (for Gnome Desktop Environment). For Fedora, {{code|PackageKit}} and {{Code|gnome-packagekit}}.
-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.
+* PackageKit authentication agent should be launched to let the {{Code|sweets}} command install dependencies. Usually it is started after being logged into a Desktop Environment session (it isn't for 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 {{Code|sweets}} command):
-  git clone git://git.sugarlabs.org/sdk/sweets.git
+  git clone --recursive git://git.sugarlabs.org/sdk/sweets.git
-  cd sweets
+  sweets/sweets upgrade
- git submodule init
- git submodule update
- ./sweets upgrade
-=== Upgrade ===
-If sweets was installed from a bundle:
- sweets upgrade
-If sweets is being used from sources, pull new commits from cloned directory:
- git pull origin master
- git submodule update

   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 {{Code|-f}} argument:
   sweets sdk/sugar:emulator=0.88 -f
-If sweets can't find proper implementation, see the {{Code|E}} lines in output of:
- sweets show sdk/sugar -vdd
-== Search ==
-It is possible to search sweets among locally known ones and registered on http://sweets.sugarlabs.org (not yet implemented). The search is based on [http://xapian.org/ Xapian] search engine. Thus, it is possible to use Xapian's [http://xapian.org/docs/queryparser.html query language].
-For command format is:
- sweets search ''query''
-Notice that [http://xapian.org/docs/queryparser.html#partially-entered-query-matching partial] search is enabled. So, the query {{Code|tele}} will be treated as {{Code|tele*}} to search all words that start from {{Code|tele}}.
-Sweets supports following search [http://xapian.org/docs/queryparser.html#searching-within-a-probabilistic-field prefixes] basing of [[Platform_Team/Recipe_Specification|recipe options]]:
-* '''interface''' the first interface from implementations list, e.g., {{Code|http://sweets.sugarlabs.org/sdk/sugar}};
-* '''sweet''' the first interface from implementations list in short Sweets notations, e.g., {{Code|sdk/sugar}};
-* '''implement''' the list of implemented interfaces;
-* '''associate''' the list of associated interface;
-* '''name''' the short name of a sweet;
-* '''summary''' sweet's summary;
-* '''description''' long sweet's description;
-* '''category''' list of category names;
-* '''license''' list of licenses;
-* '''type''' sweet's type, might be {{Code|library}}, {{Code|application}} or {{Code|activity}};
-* '''keep''' if activity, that a sweet is representing, is favorited;
-* '''tags''' the list of sweet's tags;
-* '''mime_types''' the list of MIME types activity, that a sweet is representing, supports.
-So, it possible to search only among particular sweet attributes, like {{Code|name:telepathy}} to search only among sweet names.
-Sweets support additional notation for exact searching in form of {{Code|''prefix''<nowiki>:=</nowiki>''string''}}. For example the query {{Code|name<nowiki>:=</nowiki>sugar}} will find sweets only with exactly {{Code|sugar}} name and omit names like {{Code|sugar-base}}. If search string contains spaces, wrap it to double quotes, {{Code|name<nowiki>:=</nowiki>"Sugar Commander"}}. Note, wildcards does not work in exact search case and asterisks will be treated literally.
