In a previous post I described the basic principles of PetitParser and gave some introductory examples. In this blog post I am going to present a way to define more complicated grammars. We continue where we left off the last time, with the expression grammar.
In my recent post I've mentioned that the Filesystem library can work on different kinds of filesystems. In this post I am going to walk you through the supported filesystems one by one.
After the announcement in the Moose mailing list and after various people have asked me to provide some introduction to PetitParser I decided to write short tutorial.
A while ago Colin Putney announced the Filesystem framework, a nice and extensible replacement for the ugly FileDirectory class in Pharo. While all core classes are well commented, there is a quick start missing that explains how end users are supposed to adopt the framework. This blog post should fill that gap.
While most people prefer to run SmallLint (Smalltalk Code Critics) from within OmniBrowser, the question arises from time to time on how to do the same from within a workspace script:
Gofer, a person who runs errands. Origin 1960s: from go for, i.e. go and fetch.

Over the past years several people have asked for a simple solution to export and import a Pier site into a different image. Finally this is possible. The following screen-cast demonstrates the basic steps how I export my complete website and import it into a fresh Pier image.
Magritte for Seaside allows one to automatically build Seaside components from descriptive objects. There are several possibilities to customize this 3 step process:
Early versions of Pier included the syntax to embed Smalltalk code into a page. This was a nice feature for power users, but caused certain confusion among others. Moreover it also caused potential security issues, when the permissions weren't setup properly. Never the less, as there were some people complaining about the missing feature, I am going to show how to extend Pier and its pluggable parser to support this functionality.
