PettitParser approach help
by Juan Ignacio Vaccarezza May 28, 2013

May 28, 2013

Hi all, First of all thanks for the amazing work and aswers to all. Having said that, the problem: I need to parse a log, a model that represents the lo is the following: ' AAA AAA BBB Line I don't care which can contain anything that is not AAA BBB or CCC CCC AAA CCC BBB Line I don't care which can contain anything that is not AAA BBB or CCC ' I manage to write the grammar which parses this, but then I would lilke to have all the log info digested on a result object which behaves something like this: resutlObject as size --> 3 resultObject bs size --> 2 restulIbject cs size -->2 The option that im using now is that individual parsers (meaning the parser for AAA,BBB,CCC,etc) actually retunrs an object that knows how to add themselves to the result and then, I iterate over the parser's array result asking to each object to add itself to the result. Is there a better solution? Thanks to all, Juan.

Class naming guide
by Bahman Movaqar May 28, 2013

May 28, 2013

Hi all, I noticed that since there is no `import' statement in Pharo, class names can easily conflict. What is the common naming strategy that you people use to avoid that? TIA, -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation, Deployment Consultant

Fwd: Gettext package for 2.0 - information not updated
by Usman Bhatti May 28, 2013

May 28, 2013

Hello, I am looking to see how localization works in Pharo. There is a pharo book chapter that explains how to make it work but the chapter explains the working on Pharo 1.4. http://book.pharo-project.org/book/LanguageAndLibraries/Localisation Recent changes in STHub allow to load the package in Pharo 2.0 but I see a lot of references to FileDirectory (deprecated in 2.0) and hence the tutorial in the book does not work. The other package: System-Localization does not have much documentation so that does not help either. Can someone point to a working tutorial for Pharo localization for 2.0? tx, Usman

String replacement
by Thomas Worthington May 28, 2013

May 28, 2013

I've got a string which is the header section of an email. I have a regex which will split a header field name from its data (ie, "From: jim(a)null.com" becomes "From" and "jim(a)null.com") but some header lines are long and have been continued by inserting a newline and one or more spaces. Before splitting the fields I need to undo these continuations by deleting these combinations of a newline followed by some whitespace. This would certainly be trivial in Perl or any of the normal Linux regex engines but I've spent hours on this today, equipped with the PBE2 chapter, and got nowhere. How do I do this in Pharo? Thanks, Thomas

ORM with PostgreSQL support
by Bahman Movaqar May 27, 2013

May 27, 2013

Hi all, I'm completely new to Smalltalk world so please bear with me. Coming from the Java world, I'm used to using an ORM when developing a database-backed application. What are the options in the Smalltalk world? I'm specially looking for something that supports PostgreSQL as that's what I 99.99% of the time use :-) Would you please give me some pointers along with links to the documentations?

May 27, 2013

What is the correct way to install `SandstoneDb' in Pharo 2.0? With the approach Pharo book takes[1], Pharo complains about two other packages to be installed as well: `DataStream' and `SmartRefStream'.

history graph widget
by Martin Dias May 22, 2013

May 22, 2013

Hi I would like to have a Morphic widget like this. Does anyone know if there is something already done that I could reuse? [image: Inline image 1] Maybe do it with Roassal in this way: Use the list morph, where each row knows an image morph with its corresponding slice of the graph. Each time the graph changes (for example, if a node is appended), render using Roassal the part of the graph has to be updated, and cut the rendered surface in the new slices for each updated row. Any opinion? Maybe I should think more in vectors (i.e. Athens) instead of pixels/images? Cheers, Martin
