For example, http://zn.stfx.eu serves static content and serves all Zinc demos, with the following config (part of the startup script): | id logFile staticFileServerDelegate | id := 1. logFile := 'transcript.{1}.log' format: { id }. (NonInteractiveTranscript onFileNamed: logFile) install. (ZnServer defaultOn: 8080 + id) logToTranscript; route: 'r', id printString; start. (staticFileServerDelegate := ZnStaticFileServerDelegate new) prefixFromString: 'zn'; directory: '/home/ubuntu/zn' asFileReference. ZnServer default delegate prefixMap at: 'zn' put: [ :request | staticFileServerDelegate handleRequest: request ]; at: 'redirect-to-zn' put: [ :request | ZnResponse redirect: '/zn/index.html' ]; at: '/' put: 'redirect-to-zn'.

DoubleLinkedList vs LinkedList vs Collection
by Peter UhnÃ¡k April 14, 2015

April 14, 2015

I was surprised to learn that DoubleLinkedList is descendant of Object, while LinkedList is descendant of SequencableCollection. Is there a particular reason behind this? Are they really so conceptually different that DLL is not even considered a collection? Thanks, Peter

Gitfiletree unstable on Windows
by Jan B. April 14, 2015

April 14, 2015

Hello This is me again with problems with gitfiletree. In general it works just fine, but in about 50 % cases it crashes VM. It happens to me when loading via Gofer new url: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo40/main'; configurationOf: 'GitFileTree'; loadDevelopment. Metacello new baseline:...; repository:'gitfiletree:///...'; load. or when opening repository in Monticello. Sometimes the crash is handled and dmp file is generated, but sometimes just Pharo.exe stops. Using Windows 7 64-bit, VM tried 420 (latest) from 2015-03-26 and stable from 2014-05-15, images tried multiple between 40546 to 40588 and also 30864. Here are links for dmp files: http://www.mediafire.com/download/txbxi77a4nthyxg/Pharo_dmp.zip crash1 and 2 are from stable VM and 3 and 4 from latest VM, all from image 40588. Using git from http://git-scm.com/ . Would be glad to help any further if you need.

Hi, how does one add an internal link? I have chapter 'Framework' (and file 'Framework/Framework.pillar') and 'Palette' (and file 'Palette/Palette.pillar') Can I in Framework.pillar write something like *Palette/Palette* to create a link? Currently it fails at *** Warning: PRReferenceNotFound: Can't find anchor named 'Palette/Palette' Thanks, Peter

[ANN] MorphicDoc : A project to document Morphic
by kilon alios April 12, 2015

April 12, 2015

One of the frequent questions we get asked is how to use Morphic. Unfortunately there is very little documentation for Morphic around and barely touches the most interesting concepts. I decided to start my own project called MorphicDoc . MorphicDoc is very easy to install with Configuration Browser and it works in 2 ways. a) open the Help tool (World Menu => Help => Help Browser ) and there you will find a new section called "Morphic Doc by Kilon" b) open System Browser go to MorphicDoc package and look at the class side of MorphicDocExamples class , each method is an example taken from the tutorial in help tool and you can easily execute by clicking the green arrow next to its name. Right now only 3 pages have been added but slowly and steadily more will be added. To get new pages and even new chapters make sure you reinstall the same very simple way like installing just open Configuration Browser and click "Install Stable Version" after you selected MorphicDoc. I will try to add 1 page per day and at least 1 page per week depending on my free time. So make sure you update at least once per week to get the latest version of MorphicDoc. You can report issues , advice and requests at the project page in https://github.com/kilon/MorphicDoc. Of course pull requests are more than welcomed.

Dictionary and sorting
by Hilaire April 11, 2015

April 11, 2015

Dear all, >From a dictionary, I want the keys sorted according to the values (string). I came with this method: keysSortedByValue ^ (self associations sort: [ :assoc1 :assoc2 | assoc1 value < assoc2 value ]) collect: [ :assoc | assoc key ] Is there better way to deal with it, in term of efficiency? Thanks Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

How to silently generate and remove code
by Johan Fabry April 10, 2015

April 10, 2015

Hi all, for LRP I am auto generating classes and methods, and removing them when I no longer need them. This however produces a lot of entries in the change file that are not needed at all. So I am looking into generating and removing them silently, however with not much success. Can anybody help me out in how to do the following without having entries in the changes file? - add a class (The standard subclass:instanceVariableNames:classVariableNames:category: message does not seem to have a âsilentâ equivalent) - remove a class ( aClass removeFromSystem: false. still logs to changes, apparently) - compile a method (aClass compileSilently: methodstring classified: #generated. still logs to changes, apparently) - remove a method (removeSelector: does not seem to have a âsilentâ option) - add / remove class variables (again, no âsilentâ option) - run a RBCreateAccessorsForVariableRefactoring Thanks in advance! ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
