Swiki in Squeak 4.5

Swiki was and still is one of the best (and most easy to use/maintain) implementations of a wiki. It is written in Squeak Smalltalk and I usually use the Winterlong release back from 2005. With it a Swiki server is easy to setup (just unzip and run) and as it stores the files in XML they are easy to backup, repair or query.

Now Chris got Swiki working in a recent Squeak 4.5. image also. Nice!

DataTables jQuery plugin for Seaside

If you build a web application using Seaside and Pharo, maybe using my Bootstrap wrapper project you might be interested in a good data table plugin to display tabular data.

Pharo Seaside : Looking at HTTP Traffic

If you want to easily look at the HTTP traffic in your Pharo based Seaside application then just evaluate:

       ZnLogEvent open

This will open an spy on the Zinc announcements. Then start your server using:

     ZnZinServerAdaptor startOn: 8080.

and use the webbrowser to browse your Seaside application. You will now see any HTTP exchange between the client and the server.

The video demonstrates this:

Teapot - another way for Pharo to serve the web

There are various options to write web applications in Pharo. You can use Seaside or Aida web framework or play with the new Tide framework connecting Amber with Pharo.

If you want to quickly write something you can use the plain Zn framework as this nice tutorial from Sven describes.

And now there is something inbetween that allow you to quickly write an application that serves static or dynamic content from Pharo. It is called Teapot and with a few lines of code you can provide JSON to the outside world or other REST based functionality. It also includes support for the Pharo port of Mustache (the templating engine).

The basic concept of Teapot is to define one or many URL Route(s) - either direct or as pattern (for instance with a Regexpression) and return an appropriate response from the Smalltalk side. Simple, lightweight and easy to use.

If you want to try it yourself just open this page in your webbrowser: http://lively-web.org/users/bert/Smalltalk-78.html

Really interesting are also the details (for instance on GarbageCollection and on how to run one high level language on another high language.

Here are the videos from ESUG 2014 on that:

Fun with Pharo (when writing books)

Beside the Pharo by Example, Deep into Pharo and the Pharo Enterprise book (available on CI, GitHub and as PDF) there is now also the idea of a book about "funny" things like implementing games in Pharo.

Therefore a new clone of the Pharo by Example book was created with the name "Fun with Pharo". The book is built on CI, the books source is hosted on GitHub and currently it includes already infos on how to build a digital Tamagotchi with Smalltalk or how the PhlappyBird game works.

The PDF for "Fun with Pharo" is already available.

If you want to contribute you should have a look and learn about Pillar and I would recommend to use either Online PillarHub or the new one-click image for PillarHub that you can run locally to write an own chapter.

Pharo and GoogleMaps

By accident I found http://smalltalkhub.com/#!/~smaass/GMaps a small project to access google maps from Pharo. Allows you to easily work with Google maps by querying for an address:

|g|
g := GoogleMaps geocode: 'Rue du Bel air, Paris'.
^ g address inspect

or visiting a location in the browser:

|g url|
g := GoogleMaps geocode: 'Rue du Bel air, Paris'.
url := String streamContents: [:s |
 s nextPutAll: 'https://www.google.de/maps/@';
    nextPutAll: g location x asString;
    nextPut: $,;
    nextPutAll: g location y asString;
    nextPutAll: ',16z' 
].
NBWin32Shell shellBrowse: url

Requires NeoJSON, so load this first from configuration browser.
