Securely downloading Pharo

by Wilfred Hughes

Is there any way of downloading Pharo securely? I'm trying to download Pharo itself over HTTPS, so I know I can trust the data: $ wget https://files.pharo.org/platform/Pharo4.0-linux.zip --2016-05-02 22:44:34-- https://files.pharo.org/platform/Pharo4.0-linux.zip Resolving files.pharo.org (files.pharo.org) 128.93.162.72 Connecting to files.pharo.org (files.pharo.org)|128.93.162.72|:443... connected. OpenSSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol Unable to establish SSL connection. The excellent pharo zeroconf script doesn't seem available over HTTPS either: $ curl https://get.pharo.org/vm50 curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol Looking at the script itself, it's downloading files over HTTP from files.pharo.org and executing them without verifying. I've explored files.pharo.org, but I can't see any signatures or hashes (e.g. sha256sum) of any of the files. The pharo homepage is largely available at https://pharo.org/ (although some of the styling is missing due to being served over HTTP). Have I missed something? Would it be possible to provide HTTPS and/or sha256sums for downloads? Wilfred

Re: [Pharo-users] Can you help me find this info?

by Offray Vladimir Luna CÃ¡rdenas

On minimal images, you could take a look at Cuis: http://cuis-smalltalk.org/ Is not based on Pharo, but could give you some ideas/inspiration.

[ANN] Pharo Astares Distribution

by Torsten Bergmann

Hi, I summarized some of the goodies that I wrote like - DesktopManager - QuickAccess - HubCap - WebBrowser - MessageFlowBrowser - ... into an own kind of Pharo distribution that I call AstaresDistribution. So if you already use these goodies it is easier to load quickly into a fresh image. You can load directly from Catalog or by opening Spooter, enter "Astares" and hit ENTER to load. Alternatively you can download a prebuilt image using PharoLauncher from "Pharo Contributions Jenkins" -> "AstaresDistribution" or directly from [1]. Screenshot attached. Have fun T.

Re: [Pharo-users] Metaprogramming facilities

by Peter UhnÃ¡k

1) write them by hand annoying typing required 2) use Class refactorings (right click on class -> refactoring -> class refactoring -> generate accessors; or ctrl+h+a) this will ask you to choose for all attributesâ¦ good initially, but really stupid if you are providing e.g. just getters (because then you would need to cancel genreation for all the attributes) 3) use attribute refactorings (right click on class -> refactoring -> inst var refactoring -> accessors -> select attribute) good for individual attributes 4) write the code compilation (ideally as part of some tool) MyClass compile: 'attr ^ attr' classified: 'accessing'. MyClass compile: 'attr: anObject attr := anObject' classified: 'accessing'. Much more typing, but good if you have it as part of some tool (so you can quickly script a gui that would generate it just by clicking on a checkbox or something) 5) use refactoring (this is what the System Browser uses internally) (RBCreateAccessorsForVariableRefactoring variable: #attr class: MyClass classVariable: false) execute 6) use TDD (test driven development) the Debugger will offer you to create the method and you can modify it as you work through (I don't know if TDD is already part of the broadcasted MOOC courses) Typing by hand is annoying, but it's literally two words for getter and four for setter. This mail is probably more words than all the accessors I've created this yearâ¦ so typing it by hand is no big deal. More importantly the autogenerated code is a bit stupid TBPost >> title: anObject title := anObject this is stupid, so even for generated one I select the argument, press ctrl+t (or right click + suggestions) and select 'rename' ... and rename it into something meaningful like TBPost >> title: aString title := aString But otherwise I regularly use all 1, 2, 4, 5, 6â¦ I never use 3) it's too annoying and distracting because I have to read the labelsâ¦ I can type in the getter/setter without breaking focus on what I am doingâ¦ but it just gave me an idea... :) Peter On Tue, May 3, 2016 at 9:05 PM, stepharo <stepharo(a)free.fr> wrote: > Code not tested but .... > > > #('title' 'text') > > do: [:each | > > | body | > > body := String new streamContents: > > [ :s | > > s nextPutAll: each ; cr; tab; > > nextPutAll: '^ '; > > nextPutAll: each ; cr]. > > TBPost compile: body classified: 'accessing' > > ] > > Le 2/5/16 Ã 17:35, Victor RENE a Ã©crit : > > In the TinyBlog mini-project of the MOOC, we start by creating the model. > However, since I basically finished the exercises, I wanted to go one step > further and > ask you guys, what is the correct way _not_ to write all gettters / > setters for the fields. > > > TBPost >> title > ^ title > TBPost >> title: anObject > title := anObject > TBPost >> text > ^ text > TBPost >> text: anObject > text := anObject > etc... > > > Do you do it with macros / templates / something else ? > I am having a bit of fun (although I would love that they unlock weeks 2 > to 7 for me).

[ANN] EventRecorder updated (import/export)

by Torsten Bergmann

Hi, I forgot to mention that for "EventRecorder" there was another pass on the code together with Peter Uhnak. It is now possible to import/export the recordings again and also the UI was updated accordingly (see attached screenshot) Works in Pharo 5.0 - you can load the tool from Catalog or by opening Spotter and entering "EventRecorder". Have fun T.

No need for Python or what so ever. There is a tutorial in pharoInProgress on github (attached) a chapter in deepintoPharo book on voyage. Voyage provides a really nice way to handle mongo DB and punqlite for now.

Re: [Pharo-users] Documentation about Pharo Launcher?

by Peter UhnÃ¡k

> prepackaged version of Moose 6 for Windows, Linux y Mac Moose is just Pharo image + changes; you can use the same Moose image on all platforms. And moose is just installed on top of Pharo 5 image (it's just a bunch of commands executed on top of Pharo 5 image https://ci.inria.fr/moose/job/moose-6.0/lastSuccessfulBuild/console ) So you can do it by hand, which is easy, you can download the VMs and sources here http://files.pharo.org/get-files/50/ and just copy there the moose image. I have a bundler that can take a Pharo image and create distribution for each platform together with the correct vm and platform-specific launchers, but I don't really have time right now to clean it up and make it generic (it's for one of my projects)â¦ unless you can wait until after May 15. But you can probably write it yourselfâ¦ it's a bunch of bash, makefiles, C, cross-compilation, and AppleScript. :) Peter On Tue, May 3, 2016 at 7:57 PM, Offray Vladimir Luna CÃ¡rdenas < offray.luna(a)mutabit.com> wrote: > Yes, that would be nice and easier, but I don't know if we have a > prepackaged version of Moose 6 for Windows, Linux y Mac or where I can get > it.
