=== Object of this HowTo ===

This HowTo explains how to update the data files in the wikipedia activities or how to create new activities with other languages or different selections of articles.

The procedure is not very difficult if you already have a Sugar environment setup. If you have doubts or the information provided is not adequate, please contact me at ''gonzalo at laptop dot org'' or in the sugar-devel mailing list and I will try to help and improve this page.

If you want to create a wikipedia activity in your language, and do not have the technical resources, but can help translating a few files and doing quality control, contact me and I will help you to create the activity.

=== How to Create a new wikipedia activity or update an existing activity ===

This page describes how to generate the data files needed to create a wikipedia activity like

[http://activities.sugarlabs.org/es-ES/sugar/addon/4401 Wikipedia es] or [http://activities.sugarlabs.org/es-ES/sugar/addon/4411 Wikipedia en]

[http://activities.sugarlabs.org/es-ES/sugar/addon/4401 Wikipedia es] or [http://activities.sugarlabs.org/es-ES/sugar/addon/4411 Wikipedia en].

The general idea is to download an XML dump-file (backup) containing the current Wikipedia pages for a given language, ~~this will be processed to~~ select certain pages and compress them into a self-contained Sugar activity. Whether or not to include the images from the wiki articles will have a large impact on the size of the activity.

The general idea is to download an XML dump-file (backup) containing the current Wikipedia pages for a given language, then process the dump and select certain pages and compress them into a self-contained Sugar activity. Whether or not to include the images from the wiki articles will have a large impact on the size of the activity.

Generating a Wikipedia activity requires a computer with a lot of available disk space, ideally lots of RAM and a working Sugar environment. It is probably best to use packages provided by your favorite Linux distribution or in a virtual machine. The wikipedia xml file is very large (almost 6 GB for the Spanish wikipedia, and it is even bigger in English), and you will need lots of space to generate temporary files. The process ~~has~~ a ~~long run-~~time, but it is mostly automated, although you will need to confirm success at each stage of the process before moving on to the next.

== Download the wikipedia base activity ==

You will need to download the wikipedia base from http://dev.laptop.org/~gonzalo/wikiserver/WikipediaBase-33.xo. This package includes the activity and the tools to create the data files.

You will need to download the wikipedia base from http://dev.laptop.org/~gonzalo/wikiserver/WikipediaBase-35.xo. This package includes the activity and the tools to create the data files.

You need unzip it in your Activities directory, or install it, if you do not have ~~other~~ wikipedia activity already installed.

../tools2/create_index.py --~~delete_all~~

../tools2/create_index.py --delete_old

The option --~~delete_all~~ is used to remove the old index

The option --delete_old is used to remove the old index

If you want to include images in your wikipedia activity, you can go again to your data directory and do:

Line 157:

in the header and replace the entities for stroke_color and fill_color, after that.

* activity_''lang''.py: is the startup class, sets the configuration values and starts the server.

* '''DEPRECATED, SEE BELOW:''' activity_''lang''.py: is the startup class, sets the configuration values and starts the server.

You can copy the class from another language and set the parameters. You need set the name of the class,

equal than the value in the exec value in the activity/activity.info.lang file.

Line 160:

Line 167:

If you create your favorite list based in a translation of the home page from other language, would be a good idea translate the home page too.

Now, you can test your changes, starting the wikipedia server:

'''DEPRECATED, SEE BELOW:''' Now, you can test your changes, starting the wikipedia server:

./activity_''lang''.py es_lat/eswiki-20111112-pages-articles.xml 8000

Line 177:

Line 185:

Now, in the directory dist, a new .xo file will be created and you can distribute it.

=== Notes on updates in the process ===

After version 38, with the intention of make more standard the process to allow package the activity

in distributions, we added a standard setup.py. To use it, is needed add the wikipedia initialization

parameters to the activity.info file, as is displayed in the file activity.info.en_simple

https://github.com/godiard/wikipedia-activity/blob/master/activity/activity.info.en_simple

[Wikipedia]

path = en_simple/simplewiki-20130724-pages-articles.xml

port = 8011

home_page = /static/index_en_simple.html

templateprefix = Template:

wpheader = From Wikipedia, The Free Encyclopedia

wpfooter = Content available under the

<a href="/static/es-gfdl.html">GNU Free Documentation License</a>.

<br/> Wikipedia is a registered trademark of the non-profit

Wikimedia Foundation, Inc.<br/><a href="/static/about_en.html">

About Wikipedia</a>

resultstitle = Search results for '%s'.

Another change important is that now is not needed create a activity_<lang>.py file,

because the activity starts and read the config from the activity.info file, the "exec" line need be:

exec = sugar-activity activity.WikipediaActivity

Then to create the .xo you can do:

./setup.py dist_xo es_lat/eswiki-20111112-pages-articles.xml

or to create the sources tar.bz2 file:

./setup.py dist_source es_lat/eswiki-20111112-pages-articles.xml

With this new version, testing the wiki can be done on the command line doing:

./test_server.py es_lat/eswiki-20111112-pages-articles.xml 8000

The two parameters are optional, if are not provided, the parameters in activity.info file will be used.

== Other changes needed ==

Line 183:

Line 231:

If after finish the process of the files, the images are not displayed in the pages, check if the image identifier is included in the set imageKeywords in the file mwlib/parser.py. For example, in the Quechua wikipedia, the image identifier is "rikcha" and we needed add it because was not included.

== More tools ==

=== Big image files ===

There are cases where a small group of images are very big, if you want remove them to have a smaller activity, can do:

mkdir big-images

find images -size +100k -exec mv {} big-images \;

(in this example, moving images with more than 100k to another directory)
