Slow World Menu opening
by Alexandre Bergel 26 Aug '15

26 Aug '15

Hi! When I open the world menu, the mouse cursor is intensively blinking, and opening the menu is _very slow_. This bugs has been around for a couple of weeks already. Am I the only one to see it? I have checked the cause, and apparently the problem disappear by removing the use of “Cursor read showWhile:”. The following method: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. Cursor read showWhile: [ form := reader nextImage. reader close ]. ^ form -=-=-=-=-=-=-=-=-= May be rewritten as: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. form := reader nextImage. reader close. ^ form -=-=-=-=-=-=-=-=-= However, changing the cursor has been around for quite a long time. It is strange that the slow menu is surfacing only now. Any idea why?

New features on MooseQuery
by Anne Etien 24 Aug '15

24 Aug '15

Hi, Yesterday we developed two new features in MooseQuery: - the toScope: method to go down in the containment tree. It is the opposite of atScope: that goes up. Both methods work the same way: ((classA queryIncoming: FAMIXInvocation) atScope: FAMIXClass) toScope: FAMIXMethod. This query uses the new API and returns the methods of the classes containing the methods sources of the incoming FAMIXInvocation of classA. - the ability to query the MooseGroups. Thanks to this new feature, it is possible to query directly the model or any MooseGroup resulting from a selection or an operation (union, intersection, difference…) of several MooseGroups. A full documentation’s coming, but certainly not before the end of the summer. Cheers, Jean-Christophe and Anne

Re: [Pharo-dev] Re: Object new foo
by Vincent BLONDEAU 23 Aug '15

Hi Eliot, Thanks for your help. The problem has been resolved! In fact a class was removed or renamed in Pharo, and the Moose debugger calls it just before the opening. So it created an infinite loop, because the class wasn’t understood by the system, so it opened another debugger, etc…. Do you think something can be made to not break the image and so to break this infinite loop? A solution may to open either another registered debugger, or the emergency debugger? I can create an image with the problem if needed.

The two functions you see looping are part of the implementation of primitives 195 & 196, findNextUnwindContextUpTo: (primitiveFindNextUnwindContext) & terminateTo: (primitiveTerminateTo). So if the image locks up the question is, is what is creating a circular structure of contexts, the VM or the image? I am willing to take a look at an image that contains the case. If you can create an image which enters the lop on start-up without my having to do anything I'm happy to take a look.

When you open the debugger you need to make sure the process on which it is opened is suspended and can get terminated with no problem. A different way to redo the example would be: context := Context sender: nil receiver: {1 . 2 . 2} method: (OrderedCollection>>#add:) arguments: #(10). process := Process forContext: context priority: Processor userInterruptPriority. GTGenericStackDebugger openOn: (DebugSession process: process context: context). There is a basic test for opening the debugger in GTGenericStackDebuggerSmokeTest but more could help.

[Request]: Feedback for Issue #1130: Hook for Customized Presentation Constructors (e.g. Magritte)
by Sean P. DeNigris 23 Aug '15

23 Aug '15

>From https://github.com/moosetechnology/Moose/issues/1130 : Right now, by default, a presentation constructor must be an annotated method which takes a composite (and optional context) as arguments, and configures a presentation. For example: gtInspectorStepsIn: composite <gtInspectorPresentationOrder: 10> composite list title: 'Steps'; display: [ self children ] While this serves the basic purpose, I found myself continuously duplicating info which I had already described with Magritte, as in the description mirroring the above: descriptionChildren <magritteDescription> ^ MAToManyRelationDescription new accessor: #children; label: 'Steps'; "..." yourself So, playing around, I created the following general purpose hook to give more latitude in constructing presentations: gtInspectorPresentationsIn: composite inContext: aGTInspector "..." eachPragma selector numArgs = 0 ifTrue: [ | configurationProvider | configurationProvider := self perform: eachPragma selector. configurationProvider gtPresentation cull: composite cull: aGTInspector cull: self ]. "..." This enables you to get presentations almost for free by leaning on (in this case) Magritte. The Magritte description gets a slight upgrade: descriptionChildren <magritteDescription> <gtInspectorPresentationOrder: 10> ^ MAToManyRelationDescription new accessor: #children; label: 'Steps'; "..." gtPresentation: [ :a | a list ]; yourself #gtPresentation: sets default mappings, eliminating the original duplication: gtPresentation: aBlock | wrapper | wrapper := [ :composite :context :subject | | presentation | presentation := aBlock cull: composite cull: context. presentation hasTitle ifFalse: [ presentation title: self label ]. presentation hasTransformation ifFalse: [ presentation display: (self accessor read: subject) ] ]. self propertyAt: #gtPresentation put: wrapper ----- Cheers, Sean -- View this message in context: http://forum.world.st/Request-Feedback-for-Issue-1130-Hook-for-Customized-P… Sent from the Moose mailing list archive at Nabble.com.

Updating Configurations for Pharo 4.0
by Sean P. DeNigris 22 Aug '15

22 Aug '15

Is the Moose version loadable in Pharo4.0 now fixed? That is, how would one back port a Moose feature into Pharo 4.0? The configurations already have new versions which seem to have integrated Pharo 5.0-only features, but none of these are in #pharo50 blocks. I'm asking because Camp Smalltalkers are wanting to see a demo of the GT Magritte extensions, but my projects are only loading in Pharo 4.0. Maybe I'll just do a quick jdemo project in Pharo 5.0, but a lesser problem still stands, which is that currently, I don't even know how to load my own projects with these extensions without manually declaring specific Moose package versions in my own configs, which is a hassle. Maybe I should make a ConfigurationOfGlamourMagritteForPharo40?! Any suggestions are welcome. Thanks :) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Updating-Configurations-for-Pharo-4-0-tp4845070.html Sent from the Moose mailing list archive at Nabble.com.

SmaCC 2.0.5 released
by Thierry Goubier 20 Aug '15

20 Aug '15

Hi All, I have released SmaCC 2.0.5, aligned on the main SmaCC[1] with a small fix on the Java parser, a few additional parsers (Cucumber), the addition of the Javascript parser, and continuous improvements on the performance and source code coverage of SmaCC generated parsers (with many thanks to John Brant and Don Roberts). The project is available on github[2] [1] http://www.refactoryworkers.com/SmaCC.html [2] https://github.com/ThierryGoubier/SmaCC This release is targeted at Pharo4. All parsers should work on Pharo 5, but the GUI doesn't work. Most parsers come with full AST generation and a dedicated visitor for each, and support for native language refactoring. To retrieve a specific parser, please use Metacello with the following script: Metacello new baseline: 'SmaCC'; repository: 'github://ThierryGoubier/SmaCC:v2.0.5'; load: 'SmaCC-Javascript' (SmaCC-Python, SmaCC-Java, SmaCC-Cucumber, etc...) On Pharo4 only, to retrieve the full set (gui and tests), please use Metacello with the following expressions: Metacello new baseline: 'SmaCC'; repository: 'github://ThierryGoubier/SmaCC:v2.0.5'; load Regards, Thierry

Roassal callbacks as events
by Peter Uhnák 19 Aug '15

19 Aug '15

Hi, this is just an idea that's been bugging me for some time... what if callbacks could be attached just like regular events? e.g. aBox when: TRExtentChanged do: [ :event | (self parentFor: aBox) rebuild ] Is there benefit in having some events as events and some as callbacks? Isn't event more versatile? What do you think? I should probably check how this is done in Bloc... Peter

Re: [Pharo-dev] Getting some tag in an HTML file
by Floyd May 19 Aug '15

19 Aug '15

If your scripts contain string literals with '<script>' or '</script>' in them (I've seen this before), then your mileage may vary with Tudor's approach. Also consider that script tags may have attributes, and those attributes may have single or double quotes. Also, script tags may or may not refer to javascript. Many javascript libraries use script tags for HTML template sources, for instance. These tags you'd probably want to keep (and perhaps follow the reference for the third): <script type='text/javascript'> [code here] </script> <script type='text/javascript'> document.write('<script src="somewhere.js"></script>");</script>  <script type='text/javascript' src="path/to/javascript/source.js"></script> However, something like this you might want to ignore: <script type='text/html' id='someTemplate'> <span>{{some template syntax}}</span> </script> If you can make some assumptions about what you're parsing you might be able to adapt Tudor's solution to be more robust. However, if you're trying for a general-purpose solution, I'd highly recommend using an existing HTML parsing library, not an XML parser. In general, parsing HTML as XML is the wrong approach. HTML is technically not a subset of XML (closing tags aren't required), so most true XML parsers are going to barf on it. Some further reading: https://en.wikipedia.org/wiki/Tag_soup https://en.wikipedia.org/wiki/HTML5#XHTML5_.28XML-serialized_HTML5.29 I'm new to smalltalk so I can't recommend a library, but in Java I've used Tag Soup and I've used Beautiful Soup in Python.
