Re: [Pharo-users] Traveling to PharoDays

by Joachim Tuchel

Interesting. A EU citizen flying from Munich to Brussels on transit to Paris has to be checked at the Belgian/French Border? But I absolutely buy into your connection argument for Brussels Airport... Unfortunately, I will not have time to come to Pharo Days 2015. I hope some sessions willbe recorded. Not a replacement for the networking...

(the train to london). For Thalys, the Cologne->Brussels->Paris line does *not* stop in Lille, but there is a new Amsterdam->Brussels->Lille Thalys that does. Marcus

Re: [Pharo-users] Question on temporal variables in Workspace

by kilon alios

I am not familiar with that part of Pharo because I never use temporary variables in Workspace but I did a little experiment and this is what I found . I followed these 3 steps 1) I created 2 Workspaces 2) In first Workspace I put the code |a| a:= Morph new. a openInWindow . 3) In the second Workspace I put the code a:= Morph new. a openInWindow . Now executing both examples give the result you would expect , a morph inside a window BUT if I inspect variable a in both cases , the workspace variable example returns me a Morph as to be expected on the other hand the workspace temporary variable returns me an undefined object. So that leads me to assume here that the temporary variable works as expect by destroying its reference as soon as the code is executed, hence why its called "temporary ;) On Sat, Dec 27, 2014 at 9:28 PM, nacho <0800nacho(a)gmail.com> wrote: > Hi pharoers, > In killion video tutorials I see that he uses variables not declaring them > as temporal (that is | aVariable | ). > If one does not declare variables as temporal in a workspace what kind of > variables are them? > Also why in the tutorial they appear in blue and in my workspace they > appear > in red as if there was something wrong?

I am a bit new to Pharo, anyone please correct me if I am wrong. The Workspace has a #mustDeclareVariables: method. I am assuming it is set to false by default. The colour changes once you DoIt on the code, as the variable is automatically created and bound to the workspace, so after running once, it exists. You can see this as the first time when you try inspect a variable, an error occurs. After DoIt, it changes colour, and you can inspect it.

Question on temporal variables in Workspace

by nacho

Hi pharoers, In killion video tutorials I see that he uses variables not declaring them as temporal (that is | aVariable | ). If one does not declare variables as temporal in a workspace what kind of variables are them? Also why in the tutorial they appear in blue and in my workspace they appear in red as if there was something wrong? (actually if I declare all variables as temporal using | | then all turn tu blue). Thanks in advance and best regards Nacho ----- Nacho Smalltalker apprentice.
