Created PetitParserExtension project
by Guillaume Larcheveque March 24, 2014

March 24, 2014

Hi everybody, I am using PetitParser a lot and had implemented some little tools that help me for writing or generating grammars. I put two of the most useful in the project PetitParserExtension ( http://smalltalkhub.com/#!/~Moose/PetitParserExtensions) the first one is useful when you generate grammars with lots of rules: A PPExtendedCompositeParser offers you a new way to create rules. Just define your rule as a method in the #rules protocol and it will be managed exactly like rules in PPCompositeParser. You will not have the limitation of 256 rules due to the instance variables limit but you will need to refer to your rule with the method #rule: in any other rule using it. You can mix PPCompositeParser and PPExtendedCompositeParser way to define rules. the second one is cool for token identification because it creates a parser that will parse in a time depending on token length and not the number of different tokens. A PPMultiStringParser is a tool able to create a really effective parser on a huge collection of Strings. This parser will match any string in this collection, and the longest one if two are matchable (( PPMultiStringParser on: #('tin' 'tintin')) parse: 'tintin' will match 'tintin' and not just 'tin') If someone else has implemented some tools around PetitParser, it will be great to put those all together so feel free to commit your tools in this project and to improve mines. -- *Guillaume Larcheveque*

Debugger acting up
by Diego Lont March 24, 2014

March 24, 2014

Hi all, I do not have a proper test case yet, but as I have seen it twice now I want to ask you guys if you have any problems with it. In a recent moose 5.0 image with seaside and some other suff loaded, the page would not load. Interrupting the image showed that the debugger was lost in the following loop: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: Originally it was a halt that caused the signal, and that should pop up the debugger, but instead of that it went into an infinite loop. Now I see that building Pier3 development on a pharo2 image also seems to causes this loop. The root cause is also in the mail, so maybe this is just the size of the stack ...: Startup Error: An attempt to use interactive tools detected, while in non-interactive mode Interactive Request: You are about to load new versions of the following packages that have unsaved changes in the image: Grease-Tests-Pharo20-Core If you continue, you will lose these changes: [0mNonInteractiveUIManager>>nonInteractiveWarning: NonInteractiveUIManager>>nonInteractiveRequest:title: NonInteractiveUIManager>>nonInteractiveRequest: NonInteractiveUIManager>>confirm:trueChoice:falseChoice:cancelChoice:default: MCMergeOrLoadWarning>>defaultAction UndefinedObject>>handleSignal: If anyone knows where this problem might come from, please put a mail on the mailing list. Cheers, Diego

Re: [Pharo-dev] FileSystemGit and Fuel final report

Great! I have a different (and lower priority) use case for the libgit2 bindings: Michael Feathers has done some history analysis on github repositories which weâve used at the SPA2011 egg race. Basically, commit info on method level for 4 ruby projects. I guess Iâd have to use the low level bindings to do similar things? Stephan

March 24, 2014

Can someone please help Philippe Marschall who is having trouble saving to StHub ? His account is http://www.smalltalkhub.com/#!/~marschall He seems to be able to log in to the website part, but can't save anything. Not in the Seaside repositories, nor in a new Test repository that he just created. He was able to work normally until very recently (february). TIA, Sven

Pre-resolved issues lacking information in tracker
by Ben Coman March 23, 2014

March 23, 2014

I have a minor gripe about placeholder issues logged when a developer already has a fix ready - which lack any useful information regarding the problem that was solved. As an example, for Case 13112 [1] I found the problem was introduced in build 30205 by Case 10961, which is shown in the attached snapshot. First I'll say there was value that the issue was logged even as bare as that. I did manage to isolate a problem introduced by that slice, which was only observed 500 builds later. However providing limited information creates costs later on. The consequence in this case is relatively minor - the work-around is easy and probably all that is wanted during Pharo 3 beta anyhow. The background information will probably turn up. However having to stop and ask slows down the investigation. If I knew more upfront about the original problem of Case 10961, I could consider alternative solutions for that rather than just work-around the current issue. As I said, its only a minor thing, and hopefully this is useful feedback. Keep up the good work. cheers -ben [1] https://pharo.fogbugz.com/f/cases/13112/Broken-Vistary-theme

Nautilus keyboard behavior
by Stephan Eggermont March 22, 2014

March 22, 2014

13100 triggered me to take a look at keyboard based navigation in Nautilus. These should probably be a number of different issues. There seems to be no way to get from the text pane back to methods-categories-classes-packages , both tab and right-arrow are captured. How do I open the menu on one of the top panes in Nautilus? How do I open the History navigator? Iâd expect groups and hierarchy to be selectable with a key combination when the packages pane is selected. Menu behaves interesting when use with tab key - if you are in a submenu you can tab back to the higher level menu and back down with shift-tab - if you go too far up it only reacts to shift-tab - if there is no submenu, the menu is deselected and it only reacts to shift-tab If I select a class, open the menu, select with keyboard Refactoring, right arrow to select Code rewriting, left arrow to go back and again right arrow, I get a MNU receiver of âboundsâ is nil The world menu behaves slightly different, it has no MNU but just doesnât open the submenu a second time. Moving down and up again restores the submenu. The removeEmtyCategoriesFrom menu item can be selected when there is no class selected. This gives a MNU Stephan
