String to number conversion issues
by Larry White Sept. 18, 2011

Sept. 18, 2011

Hi, I need to convert web input (Strings) to decimal numbers. I have a regex that will recognize numeric strings, but not all of them can be converted to a number with asNumber. For example, anything with a leading $+ fails, as does anything beginning with '.' (even though .3 isNumber answers true.) or '-.' Is there any code for dealing with this kind of thing (ie a method to be called before calling asNumber or a more robust library for string conversions? Given that all web input is strings and a lot of it is decimal numbers, i have to believe there is code somewhere that does this safely, maybe even with tests. :) Thanks.

New version of Little Number Chapter
by StÃ©phane Ducasse Sept. 16, 2011

Sept. 16, 2011

Hi guys I took into account the remarks of mariano and I imagine that the chapter improved. It can be obvious for some people but I like to make sure that we all find this obvious. Because it is not difficult once you spend a little time on it. Now if somebody wants to extend and improve, he/she welcome. I will continue to work on the others chapters.

Clarify VM download info on the website
by Simon Denier Sept. 16, 2011

Sept. 16, 2011

I was looking for a Cog VM with plugins and the information on the website is not very clear about the best way to get one. First, on the download page there is still a link to the old CI server (or is it still used?) http://www.pharo-project.org/pharo-download Second, the link for the Cog VMs points to http://www.mirandabanda.org/files/Cog/VM/ Unfortunately, these VMs come with no plugin. Why not advertizing the Cog VMs on https://ci.lille.inria.fr/pharo/view/Cog/ ? (at least the blessed ones) -- Simon Denier

State of art for testing tools in Pharo?
by Simon Denier Sept. 15, 2011

Sept. 15, 2011

I would like to know what's the state of the art when it comes to tests in Pharo. What are the habits? The best practices? Is there any ongoing development? I stumble upon that this morning (through twitter) http://www.lshift.net/blog/2011/09/13/checking-squeak-quickly Especially, I am interested in the following topics: - any framework to perform BDD? What's the status of SSpec? I also saw that Sean was starting to play with Cucumber, I would be very interested to see that - developing a Seaside app in TDD/BDD mode? Is there a tutorial out there about that? I stumbled upon Seaside Testing, which looks like an interesting layer http://www.shaffer-consulting.com/david/Seaside/TestingComponents/TestingCo… -- Simon Denier

CSS queries on an HTML Document
by jasiek Sept. 12, 2011

Sept. 12, 2011

Hey, I've looked at a couple of packages that are available on squeaksource, but I couldn't find exactly what I was looking for. Is there a package for Pharo that would let me query a document through CSS selectors and return a matching collection of nodes?

Simple math editor/typesetter
by Nick Chen Sept. 12, 2011

Sept. 12, 2011

Hi I'm working with some simple math equations and am looking for a nicer way to display them. Is there any existing work that I might be able to re-use/build upon? For instance, given this equation, (1+2/3)*4 I would like to see it displayed like the Equation Editor in Microsoft Word or the equations in a Mathematica notebook. See attached screenshots: http://forum.world.st/file/n3805250/word.png http://forum.world.st/file/n3805250/mathematica.png I'm not looking for anything fancy. Something simple to get me started would be helpful as well. I looked briefly at Dr. Geo but I don't think it support displaying equations in that manner.
