Hi werner to load a slice: - select it and press load. to create a slice - + slice - then select the package that will compose the slice - save the slice in the inbox Can you retry and let me know what did not work?

Re: [Pharo-dev] Mocks are missing in Pharo (from thread OSProcess is missing)

by stepharo

Denis We are working since 4 years now to get - have a small kernel + tests - be able to load nicely configurations We should not add something else than Sunit for tests of the small kernels tests. Now people can use whatever they want to test their system but for the core we are really picky because loading on single package may add far too many dependencies. and it means - more time to load - more time to debug - more time to just understand what did not work during the bootstrap. So our goal is to shrink the minimal core and not to extend it. So we will add mock by hand if we need them. I agree with Guillermo. Far too much pain.

Re: [Pharo-dev] Odd literal in metaclasses methods

by Nicolas Cellier

Because CompiledMethod>>methodClass expects a classical literal binding className->class methodClass "answer the class that I am installed in" ^(self literalAt: self numLiterals) value. But there ain't no binding for the metaclass which is accessible only indirectly thru the class (you write Object class, not ObjectClass). So it is a kind of hack to unify class and metaclass behavior... Note that the hack is necessary and used by the VM for resolving super send, so think twice if you want to come with a better hack, it's possible but also and advanced topic. 2016-10-29 18:23 GMT+02:00 Henrik Nergaard <henrik.nergaard(a)uia.no>: > Every method implemented in the class side includes a literal: > ânil->theMetaClassâ. > Object class methods collect: [ :cm | cm literals last ]. > > What is it used for? > > Best regards, > Henrik > >

Odd literal in metaclasses methods

by Henrik Nergaard

Every method implemented in the class side includes a literal: "nil->theMetaClass". Object class methods collect: [ :cm | cm literals last ]. What is it used for? Best regards, Henrik
