Not enough manpower, I asked about this before, but it's not a priority. It was "good" enough until now, and with move to git it probably won't matter for much longer. Also let's encrypt isn't just about getting a cert... you need to fully automate updating the certs (which occurs every three months)... so more work.

Is there a way to enable the arrow keys in the method list in Nautilus in Pharo5

by PAUL DEBRUICKER

I seem to remember that you used to be able to click on a method in the method pane of a browser and then use the arrow keys to navigate up and down in that list. Is there a setting I should flip to enable that now? If not how would one go about turning that on? Thanks Paul

Re: [Pharo-users] Cryptography packages

by Esteban A. Maringolo

Hi, I just adapted the latest version of the Cryptography package in SqueakSource (Cryptography-rww.49) and removed everything that was already in the Pharo 5.0 image and modified what was necessary to have all the tests passing. There is still a pending organization of the Cryptography classes and packages per se, but this should be the reference implementation in Pharo. http://smalltalkhub.com/#!/~Cryptography/Cryptography/ Name: Cryptography-EstebanMaringolo.50 Author: EstebanMaringolo Time: 15 September 2016, 2:17:35.340244 pm UUID: 903f4f9d-166d-49c6-bf2e-31ebfcfe3c26 Ancestors: Cryptography-rww.49 It's weird (to say it softly) to upload a Cryptography package using plain text user credentials over an insecure HTTP connection. #TheIrony Regards, Esteban A.

Re: [Pharo-users] pillar questions

by Damien Pollet

I've been cleaning the book archetype's makefile this afternoon. I suspect there is no list of chapters because the example is quite minimal. Enterprise Pharo was the one Thibault and Yann worked with, so I need to compare with it. The recent work on pillar was about removing superfluous responsabilities and moving it towards a simpler markup renderer. Chapter numbering is a global information, which is OK in LaTeX because it can be computed by TeX during its compilation pass; however HTML chapters are just generated one for one following the pillar files.

letsencrypt smalltalkhub ?

by PAUL DEBRUICKER

Hi - Has anyone looked into adding https://letsencrypt.org/ to the servers/vms Smalltalkhub runs on so we can have https access by default?

Re: [Pharo-users] double dispatch example

> I was thinking about the code in Pharo. > > Plenty of examples: >> - Converting money > > can you tell me more about this one? I mean summing and converting different money. Here is the whole idea: 1 EUR = 662 CLP (Chilean pesos) You have a class Money to which you can sum other money. Object subclass: #Money instVarNames: âvalueâ âI omit here the accessors of value. Note that generating the accessors of value produces a method value1, you have to rename it" Money>>+ anotherMoney self subclassResponsibility Money>>sumWithEUR: money self subclassResponsibility Money>>sumWithCLP: money self subclassResponsibility Money>>= anotherMoney ^ self class == anotherMoney class and: [ self value = anotherMoney value ] Money >>printOn: str "Useful for debugging" super printOn: str. str nextPut: $<. str nextPutAll: self value asString. str nextPut: $>. You have two subclasses: Money subclass: #EUR Money subclass: #CLP EUR>>+ anotherMoney ^ anotherMoney sumWithEUR: self EUR>>sumWithEUR: money ^ EUR new value: self value + money value EUR>>sumWithCLP: money ^ CLP new value: (self value * 662) + money value CLP>>+ anotherMoney ^ anotherMoney sumWithCLP: self CLP>>sumWithEUR: money ^ EUR new value: (self value / 662) + money value CLP>>sumWithCLP: money ^ CLP new value: self value + money value Here is a test: TestCase subclass: #MoneyTest MoneyTest>>testSum | clp1 eur1 clp2 eur2 | clp1 := CLP new value: 3500. eur1 := EUR new value: 10. clp2 := CLP new value: 5000. eur2 := EUR new value: 20. self assert: clp1 + clp2 equals: (CLP new value: 8500). self assert: clp1 + eur1 equals: (CLP new value: 3500 + 6620). self assert: eur1 + eur2 equals: (EUR new value: 30). self assert: eur1 + clp2 equals: (EUR new value: 5000 / 662 + 10). To be really complete, the example also needs to implement hash and the test should also test equality. I hope it helps!

Maybe you should have a look to Enterprise Pharo book pillar template ? https://github.com/SquareBracketAssociates/EnterprisePharo But apparently I'm not able to compile last version ... make book fails On Thu, Sep 15, 2016 at 2:06 PM, Tudor Girba <tudor(a)tudorgirba.com> wrote: > Hi, > > I see that in the new book template, we have both a book.pillar that includes the chapter files, and a pillar.conf that is mostly empty.

pillar questions

by Tudor Girba

Hi, I see that in the new book template, we have both a book.pillar that includes the chapter files, and a pillar.conf that is mostly empty. Is pillar.conf still used? If yes, what should it contain? If I embed the chapters in a book.pillar and I render the whole book, the numbering of the second chapter starts from 1 (instead of 2) when I render in html. Any idea how to do it differently? Cheers, Doru -- www.tudorgirba.com www.feenk.com "Yesterday is a fact. Tomorrow is a possibility. Today is a challenge."

Re: [Pharo-users] What are the best practices for an open source project with Pharo?

by julius

Thank you very much Stepharo and Ben, your answers are very helpful. I also realised that I should read the Monticello chapter in the book again. It's amazing how much functionality Pharo provides out of the box, sometimes almost too much :) -- View this message in context: http://forum.world.st/What-are-the-best-practices-for-an-open-source-projec… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
