The problem with xxxUser is that right now I manage two "User" concepts: what NickServ understands as a user, and what Chromia understands as a User, both of them different from an "IRC User" understood as someone or something who is connected to IRC.

I was thinking about how less classes make a system simpler and that I should remove it because the functionality is identical to that of a Dictionary.

I built the parser for it by translating parts of the BNF grammar into PetitParser. The other one is parsing the message that a user types in the client as a command to to the bot, for example "!sayto #pharo Hello, my name is Chromia".

IÂ´m rather partial to them :D Glamour is really great to write interfaces and I really like it. Now, if you develop a browser on top of glamour, you also need the moldable glamour debugger. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

That way I can first explain how the framework is built, so I can transmit the benefits of building it this way instead of mashing it up all together (which is how I began :D). Then I can explain how to use that framework to write your own bot, which again makes the benefits stand out. At the moment IÂ´m going over some decisions that I feel can be improved. >From the top of my head: - Class names are awfully chosen. Besides almost every one of them having IRC as a "namespace" prefix, some like IRCUser donÂ´t convey enough meaning. - IRCConfiguration could be replaced by a dictionary since itÂ´s nothing more than a bunch of data.

If you do it with Chromia, many details (such as network stuffs I guess) won't be shown. But this gives you the possibility to implement a great bot. If you do it without Chromia, you can show all the details so that the reader learns a lot of Pharo. Both are fine I would say.

gtinspector deconstructed

by Tudor Girba

Hi, I took a bit of time to describe how the GTInspector works, what makes it different, and to provide hints for several usage scenarios. http://www.humane-assessment.com/blog/the-moldable-gtinspector-deconstructed It's a long post, I know :), but please take a look. As you might know, this is the default inspector in the Moose image, but it can also be loaded in a fresh Pharo image. I am particularly interested in the following: - if you never used it, and tried it now, what don't you like? - if you used it, was there anything that you did not know? - and of course, what do you like about it? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

what would be fun is to see if we can build a little tutorial that show to newbies how to write a simple IRC bot. Would you be interested to work on that? Because I would love that my son is able to build one with Pharo.

Hi sergi publish you code! It sound exciting.
