Trait exclusions
by Frank Shearar June 4, 2013

June 4, 2013

I have a Trait TGroup that requires #*, #identity and #inverse. I want to construct a TField by composing TGroup with itself. One TGroup will form the operations #*, #one, and #reciprocal while the other will form #+, #zero and #negated. I don't want #identity or #inverse, because these apply to one operation, and it makes TField's API ambiguous. That's what TraitExclusion is for. I had thought I could say (TGroup @ {#identity->#zero. #* -> #+. #inverse->#negated} + TGroup @ {#identity->#one. #inverse->#reciprocal}) - {#identity. #inverse} but TraitComposition >> #- says that exclusion binds tighter than +. So in effect the above composition is the same as TGroup @ {#identity->#zero. #* -> #+. #inverse->#negated} + (TGroup @ {#identity->#one. #inverse->#reciprocal} - {#identity. #inverse}) In short, to remove the undesirable #identity and #inverse I have to exclude from both sides of the composition: TGroup @ {#identity->#zero. #* -> #+. #inverse->#negated} - {#identity. #inverse} + TGroup @ {#identity->#one. #inverse->#reciprocal} - {#identity. #inverse} My question is this: what is the reason for - binding more tightly than +? Why is it _not_ desirable to have - distribute over +? frank

MetacelloRepository
by Hilaire Fernandes June 4, 2013

June 4, 2013

Hello, To build DrGeo I use the squeaksource MetacelloRepository (example bellow). I can not find it in SmalltalkHub? I can see in PahroExtra/XMLParser ConfigurationOfXMLParser, is it the same as ConfigurationOfXMLSupport. Can I find equivalent of ConfigurationOfXMLSupport matching the exact same XML source version? Unhelpful, I did not find how to browse the source form Smalltalkhub to explore online the ConfigurationOf... code. Thanks Hilaire baseline1012: spec <version: '10.12-baseline'> spec for: #pharo do: [ spec blessing: #baseline. spec project: 'XML Parser' with: [ spec className: 'ConfigurationOfXMLSupport'; version: '1.0.1'; loads: #('default'); file: 'ConfigurationOfXMLSupport'; repository: 'http://www.squeaksource.com/MetacelloRepository']. spec package: 'DrGeoII-Core' with: [ spec requires: 'XML Parser']] -- Dr. Geo - http://drgeo.eu

I'm not sure such a thing can be done automatically from another image.

Hi, Andrei joined Camillo and extended a bit the ZeroConf infrastructure to make it easy for other projects to generate install scripts. As a consequence, we now have: http://get.moosetechnology.org The Moose-specific customization code can be found in the Moose-Development-Tools package from: http://www.smalltalkhub.com/mc/Moose/Moose/main The scripts are generated via the Pharo command line like: Pharo/pharo-ui moose-latest-dev-4.8.image moosezeroconf Cheers, Doru -- www.tudorgirba.com "No matter how many recipes we know, we still value a chef."

Bug in SmalltalkHub "delete package"
by Mariano Martinez Peck June 3, 2013

June 3, 2013

Hi guys. I tried to remove a package from the "remove package" button in the website. The package is indeed removed from the website, but if you take a fresh image, add the repository and add it to monticello, you still can see and browse the removed package.... any idea how to solve it? I need to remove packages for real... thanks! -- Mariano http://marianopeck.wordpress.com
