[Pharo-project] Merlin: a library to build Wizards
by Cyrille Delaunay Nov. 23, 2009

Nov. 23, 2009

Hi everybody, Just send this email to inform you that I have developed a small library ( called 'Merlin' ) that provide a simple structure to build Wizards. It is available on squeaksource at: http://www.squeaksource.com/Merlin. You will find a small example in the class side of 'WizardControl'. I have been making this library to build a Moose wizard that enable to select packages and some importations informations. Therefore, you can see this other example by loading Moose with: 'ConfigurationOfMoose loadDefault '. It will load all required classes. The Moose Wizard will be in the package Moose-Wizard. So, feel free to test it or use it if needed :)

[Pharo-project] RB doesn't preserve code formatting even in the simplest cases.
by George Herolyants Nov. 23, 2009

Nov. 23, 2009

Just an example: given there is a method without arguments which has several statements separated by empty lines. If you then try to rename this method you lose all the empty lines. I've checked it in the latest pharo-dev and in pharo-core 10491 with the latest AST-Core-lr.30, Refactoring-Core-lr.77 and OB-Refactory-lr.170. I've opened an issue: http://code.google.com/p/pharo/issues/detail?id=1493

[Pharo-project] DateAndTime/TimeStamp can't handle times with nanoseconds - although Time does
by Udo Schneider Nov. 23, 2009

Nov. 23, 2009

All, while writing a log file parser which parses log entries with nano-second timestamps I hit the following issue: Time instances can handle times down to nanosecond level. So something like this t := Time hour: 12 minute: 34 second: 56 nanoSecond: 1. is valid and works w/o problems. However DateAndTime and subclasses are not able to deal with Time instances whose nanoCount is ~= 0. E.g. the following fails: dt := DateAndTime date: Date today time: t. ts := TimeStamp date: Date today time: t. I've opened an issue for this: http://code.google.com/p/pharo/issues/detail?id=1487 CU, Udo

[Pharo-project] Safe and Quit can be dangerous
by Lukas Renggli Nov. 22, 2009

Nov. 22, 2009

I clicked on 'safe and quit' in the latest Pharo 1.0rc1 image. Just before the window closed I saw a debugger popping up and now my image is broken. The VM crashes shortly after being able to interact with it. This is not the first time that happened to me. Below the stack trace of the debugger.

[Pharo-project] Interval>>basicAt: fails
by Simon Denier Nov. 22, 2009

Nov. 22, 2009

Try the following (1) (1 to: 10) at: 2 returns 2 then (2) (1 to: 10) basicAt: 2 raises an exception It is surprising. Problem is that Interval redefines at: but in (2), the lookup retrieves Object>>basicAt: which only works for indexable objects (which an interval is not). So Interval should also redefine basicAt: ? -- Simon

[Pharo-project] Returning an Error Code from a Headless Script
by Rob Rothwell Nov. 21, 2009

Nov. 21, 2009

Can the current Pharo and VM return an error code from a headless script in the same way similar to a VBScript: WScript.Quit(999) Or...will this take some VM hacking? Thanks! Rob

[Pharo-project] Managing images: new files vs. new folder
by Schwab,Wilhelm K Nov. 21, 2009

Nov. 21, 2009

Hello all, How do you handle a new version of Pharo? Obvious choices are to unzip in the same directory with the previous image, and to create an image-specific directory. I have succesfully put various images in one folder in the past, but I worry about MC stepping on itself in the then common package cache. There are some advantages to that approach, but if MC gets into trouble, it's a bad idea. Bill
