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.

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.

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' 
].

Beta Test Scratch on the Pi

The Pi version of Scratch (based on Squeak Smalltalk) is available for beta testing. Feel free to help moving it forward.

It is not the only implementation: Phratch (based on Pharo Smaltalk) is basically running on the Pi too.

You may ask what are the differences between Scratch and Phratch: if I understood correctly from the discussion on the lists I think the Squeak version now has a paid maintainer (Tim Rowledge) and follows the original Scratch for kids. Phratch from Jannik Laval is more oriented towards a "Scratch for grown ups" and tries to profit from the cleaned up Pharo system and infrastructure.

Nice if you like to write books or documentation. The project also includes mods/bundles/packages for text editors, that provide improvements for pillar files editing.
