RFC Minecraft Server

by Ben Coman

I'm not ready to do this yet, but just surveying interest. I'm thinking of creating a Minecraft server using Pharo. My kids are enthusiastic about playing Minecraft and I think its a great platform to grow their creativity and cognitive skills per [1]. Much better than passively watching TV!

Could I just clarify if this was a "crash" where the Image exited, or a "lockup" where the Image froze. Since the code you develop and execute runs in the same thread as the IDE, an error in you code that (for example) loops forever will block the UI from operating. Do you know about the system escape keypress [Alt .] "alt-period" for breaking out of such a situation? > I can't copy/paste from Google Chrome (on ubuntu 14.04) while I could > copy/paste from other software like Gedit or Firefox. I'm on Debian 8 Jessie which uses MATE Desktop Environment 1.8.1. Its similar vintage to 14.04 but I don't know what desktop it uses? I just downloaded the latest build 50636 and tested against Chrome. I had no problem copying text from a random web page into a playground in Pharo. But I may have a different VM.

Problems/Suggestions with Pharo IDE

by ClÃ©ment Dumazy

Hello, I'm a French student who have learned Pharo for 2 months during a university course. As this was the first time I use Pharo IDE and the first time I program in Pharo, my teacher suggested me to send a mail on the mailing list if I encounter problems. I encountered some problems/suggestions with using the IDE : - As I crashed the IDE several times, is there a way to automatically save the image every 5 minutes (or every other frequency) to avoid the loss of my work ? - I can't copy/paste from Google Chrome (on ubuntu 14.04) while I could copy/paste from other software like Gedit or Firefox. - Last problem that I have seen, is that I couldn't use Pharo on my windows 10 Computer. I have downloaded the last version (windows version) on pharo.org and when I try to execute it (without and with administrator mode), I have a pop-up who appear. I made a screenshot of this pop-up and put it in attachment to this mail. I hope that I have posted this mail in the good mailing list. Thanks for reading, Clement

Re: [Pharo-users] How to access XML tag name?

by HernÃ¡n Morales Durand

Hi Stephane, Do you want to extract subtree from a XML? Or just extract the text in specific nodes? I think StAX parser is more friendly for selecting nodes (you don't have to subclass), i.e.: | parser doc | doc := '<?xml version="1.0" encoding="iso-8859-1"?> <FILMS> <FILM annee="1958"> <TITRE>Vertigo</TITRE> <GENRE>Drame</GENRE> <PAYS>USA</PAYS> <MES idref="3"/> <ROLES> <ROLE> <PRENOM>James</PRENOM> <NOM>Stewart</NOM> <INTITULE>John Ferguson</INTITULE> </ROLE> <ROLE> <PRENOM>Kim</PRENOM> <NOM>Novak</NOM> <INTITULE>Madeleine Elster</INTITULE> </ROLE> </ROLES> <RESUME>Scottie Ferguson, ancien inspecteur de police, est sujet au vertige depuis qu''il a vu mourir son collegue.

Amoureux de la jeune femme Scottie ne remarque pas le piege qui se trame autour de lui et dont il va etre la victime... </RESUME> </FILM> <FILMS>'. parser := XMLPullParser parse: doc. [ parser isEndDocument ] whileFalse: [ parser if: 'FILM' peek: [ : found | Transcript show: found name , ' -> ' , found attributes asString; cr. parser next. Transcript show: parser tagName ]. parser next ] Anyway if you want to try with SAX, have a look at #test01ParsingNodes and add some halts in BioNCBIBlastSAXParser to see it in action (that's in BioSmalltalk).

Re: [Pharo-users] How to access XML tag name?

by stepharo

This is more complex than that. Because I would like to have a visitor generated from the token I give. And this start character end does not really help me. Because in SAXHandler I have start where I should store the properties same in characters: to store the name end where I should invoke the visitor Now it means that I should only store the information for the tag I want. Does anybody already did that and publish it? I know doru did that in the past. I will try.
