Macros?
by Debiller 777 June 12, 2018

June 12, 2018

Well, I've already asked about adding new literals to pharo or Smalltalk in general, however this time I have a better idea: macros. Can they be added? Because if I understand correctly they may be the only way to do that.

Hi Paul, I moved the discussion to pharo-users because this has nothing to do with Pharo developement and people could get upset. 2018-06-09 13:10 GMT-03:00 Paul DeBruicker <pdebruic(a)gmail.com>: > Hi > > I think we're doing OK and that its a "discoverability" problem not a "does > not exist or work" problem.

If we don't have the resources of Facebook/Twitter/Google then why we are integrating their solutions? The real value of a framework is evolving to enable new refined instantiations. This is not a problem of being covered by fashioned tools, the problem is we are "buying" solutions from other ecosystems where they don't care at all about Pharo, Seaside, Iliad, etc. We stop building systems to integrate modules. Standard solutions like Bootstrap don't came for free, it has a cost, for example if you have to customize a component, you automatically loose the value of the Smalltalk environment. But this cost is usually hidden behind promotion and noise, the tools survive more than developer investment, and usually after a few years the developer has to invest more time and energy learning and using a newer external library... losing again the chance to gain experience cycles with tools built for its own niche. > > For static-site generators you'd probably want to use Teapot > (http://smalltalkhub.com/#!/~zeroflag/Teapot) and just write the generated > HTML to a file.

Pharo 6, bad debugger behaviour
by Tim Mackinnon June 8, 2018

June 8, 2018

Hi, Iâve noticed lately when using a reasonably recent Pharo 6.1 setup that if I restart a method in the debugger - particularly from a breakpoint or correcting a dnu issue the environment frequently locks up. Fearing the worst (after a few seconds), if I repeatedly press cmd . (Say 5 times) after 10 seconds more it comes back with 30 debugger Windows typically with something like Instance of Xxxx dnu: #someMethod (which is legit as I might have a now corrupt inst bar). I understand the error, but why does it lockup and require the cmd . Dance? I dont recall earlier Pharos doing this (and not other smalltalks). Should I report this? Tim Sent from my iPhone

by Marcus Denker June 8, 2018

Hi, If you -> submitted an issue in the past -> have been involved in some discussion about an issue ===> please check the issue tracker. There are many cases where e.g. - some issue has been fixed but the issue tracker entry is not closed - where a discussion came to a conclusion but no action happened. - you reported issue has been fixed in the meantime but the issue tracker entry is still open. https://pharo.fogbugz.com/f/filters/57/All-newest-first We have right now 471 open issues, I am sure we can get that number down!

Why do #select:thenXxx methods not return their result
by Tim Mackinnon June 8, 2018

June 8, 2018

Hi - are the methods like #select:thenCollect: frowned upon? They seem quite readable , however in using them Iâve noticed that unlike the core methods they done return the result of evaluation (they are missing a ^). This is a shame, but possibly an oversight? Tim Sent from my iPhone

Understanding ZnJSONReader mapping?
by Tim Mackinnon June 7, 2018

June 7, 2018

Hi - is there something I can read/study to get a bit more familiar with Json mapping? I have read the Pharo enterprise book (chapter 8). Iâve been using NeoJSONObject but then it occurred to me that maybe I could map better domain objects directly and simplify things. However it seems that the intent of mapping is just for simple things like an array of points - whereas if I have 15 different domain objects (albeit with a type key), then Iâm wondering if I should just wrap json nodes on usage? In fact Iâm wondering what the point of mapping is if itâs so simple - or maybe Iâm missing an important concept? Tim Sent from my iPhone

Re: [Pharo-users] more on "can't get keyboard shortcuts to work on Mac"
by Gregg Williams June 7, 2018

June 7, 2018

Tim and Ben, Thanks for your help. Sorry for not being clear. When I said "I just can't get keyboard shortcuts to work on Mac," what I should have said is "I just can't get Pharo-specific shortcuts to work on the Macintosh implementation of Pharo" (6.1 is what I'm using BTW). Maybe I should have said "keymap shortcuts"? I'm talking about things like Meta+Shift+f for 'find class', and Meta+x, Meta+m for 'remove method'. I've looked for what the definition of Meta is for Mac OS. All I can find is meta-click is Shift+Option+click, but that doesn't seem to work. Option + <many keys> gives "special characters" like â, Ã, and Å. I hope that now you can simply say, "Oh, of course, what you need to do isâ¦". Thanks! > I just can't get keyboard shortcuts to work on Mac. I?ve tried a lot of stuff, more than I can list here. Here are some things I?ve tried: > > * searching the Pharo by Example book > * turning off all Mac keyboard-macro programs > * switching from extended to standard US keyboard > * looking at options in System Preferences > Keyboard > > > If you?re on the Mac, do you have this problem? If so, what?s your solution? Thanks! >

Morph & MVC tutorials
by Matias Maretto June 7, 2018

June 7, 2018

Hi guys, I have been doing some things with Dolphin, actually feel very confortable with it, but now I am trying to learn Pharo. I have noticed that many things are quite similars, but others are very differents, one of this things is the Visual Part, can someone point me out some good tutorial for Morph and MVC, I trying to understand the use of these two "worlds" and I want to "play" a little with them. Thanks. MatÃas.
