GitFileTree repository creation crashes Pharo

by Jan BlizniÄenko

Hello I decided to give another try to GitFileTree. My last try was 2 years ago, but I had to revert to simple filetree because of frequent crashes while saving to gitfiletree repository on Windows. Today my attempt ended much more quickly. What I did and what was the result? 1) Downloaded Pharo 5 for Windows from http://pharo.org/download and opened it 2) Found GitFileTree, selected Install stable version and confirmed I want to install although it was not tested for Pharo 5 -> it loaded without visible problem 3) Opened Monticello, +Repository, selected empty directory I just created, clicked Ok -> image closed (like if I killed Pharo process - no error, no question, just closed) So, I am not even sure how to even debug it. Is this any common problem or did I miss something? I tried it also in latest Pharo 6, I tried also loading using code from github://dalehenrich/filetree:pharo6.0_dev/repository , I tried also latest VM, but no luck so far. I have Windows 10 64bit.

Spec way to embed something into Scrollable Wrapper

by Peter Uhnak

Hi, is there a Spec way to take something and embed it into scrollable pane? I haven't seen anything like that in Spec itself (List/Tree that has scrollbar has it on Morphic side); but maybe there is a way to embed Spec inside some Morph and then embed the Morph back into Spec? Obviously that's awful, but if someone can point me to a Morphic solution I could try to make a Spec adapter for it. Thanks, Peter

You can find it in the VMMaker package (not VMMaker.oscog) at http://source.squeak.org/VMMaker, see class JSCodeGenerator. Dave

Re: [Pharo-users] Easy question about syntax.

Also, youâre not setting the instance variable - just returning an OrderedCollection - is that what you want to do? e.g. setting the trees instance variable: trees ^ trees ifNil: [ trees := OrderedCollection new ] like Bernardo said, when you call #trees from within the #trees method (with self trees) - like in your first example, you created an infinite loop. > On 11 Mar 2017, at 3:36 pm, Bernardo Ezequiel Contreras <vonbecmann(a)gmail.com> wrote: > > i think that in the first case you access an instance variable trees while in the second case you send a message trees to self that cause an infinite recursion. > am i right? > > > On Sat, Mar 11, 2017 at 12:57 AM, sergio ruiz <sergio.rrd(a)gmail.com <mailto:sergio.rrd@gmail.com>> wrote: > I have a simple one, but i need to understand what is going on.. > > i have something like > > Tree > > with a class method > > trees > ^ trees ifNil: [OrderedCollection new] > > i initially ran into trouble with it locking my image up because i wrote it as: > > trees > ^ self trees ifNil: [OrderedCollection new] > > what is the semantic difference between these two calls? > > THanks! > > > > ---- > peace, > sergio > photographer, journalist, visionary > > Public Key: http://bit.ly/29z9fG0 <http://bit.ly/29z9fG0> > #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV > http://www.Village-Buzz.com <http://www.village-buzz.com/> > http://www.ThoseOptimizeGuys.com <http://www.thoseoptimizeguys.com/> > http://www.coffee-black.com <http://www.coffee-black.com/> > http://www.painlessfrugality.com <http://www.painlessfrugality.com/> > http://www.twitter.com/sergio_101 <http://www.twitter.com/sergio_101> > http://www.facebook.com/sergio101 <http://www.facebook.com/sergio101> > > > -- > Bernardo E.C. > > Sent from a cheap desktop computer in South America.

Re: [Pharo-users] Easy question about syntax.

by Bernardo Ezequiel Contreras

i think that in the first case you access an instance variable trees while in the second case you send a message trees to self that cause an infinite recursion. am i right?

Easy question about syntax.

by sergio ruiz

I have a simple one, but i need to understand what is going on.. i have something like Tree with a class method trees ^ trees ifNil: [OrderedCollection new] i initially ran into trouble with it locking my image up because i wrote it as: trees ^ self trees ifNil: [OrderedCollection new] what is the semantic difference between these two calls?

Mini Pharo -> JavaScript translator?

by Alexandre Bergel

Hi! Is there a simple way to translate Pharo code into Javascript? There is Pharo JS, but I cannot load it in Pharo 6. There is the amber compiler, but I cannot find a version for Pharo. Amber takes the approach of translating everything into JavaScript, including the Smalltalk object model. While this is great for fan of bootstrapping images, it produces large javascript code. Is there a kind of Slang for JavaScript? I am looking for something minimal.

Very nice, much needed, much appreciated. PS: Why no html (yet) ? HTML chapters make it easy to show people where to look. > On 10 Mar 2017, at 20:54, stepharong <stepharong(a)free.fr> wrote: > > Hi > > After several iterations and some month of efforts, the new version of Pharo by Example is finally available in print form and pdf. > > http://books.pharo.org > > > Tx all the contributors. > > -- >
