Re: [Pharo-users] Pharo and fileout folder

Under P7, from the class browser, when I fileout, it does not ask me!

Pharo and fileout folder

by Pablo Frias

Hi everyone, I noted that Pharo resets the location of output when doing fileout to the default Pharo folder, even after several times I changed it to another folder. Is that an expected behaviour? Thanks, Pablo

Re: [Pharo-users] TextEditor

by Hilaire

Hi Peter, Thanks to point Spec and TextPresenter (TextModel was deprecated) which I did not know until now. Is it related somehow to TextEditor? Or Rubric which I learn about recently? Can it contain arbitrary Morph with some layout? In the image, I did not find clue about that, and get lost exploring the classes. Thanks for any enlightenments Hilaire Le 21/09/2018 Ã 18:01, Peter Uhnak a Ã©critÂ : > depending on your use-case you might also consider Spec or > PlaygroundÂ http://forum.world.st/Using-Playgrounds-as-a-notepad-tp4869129p4869227.html > -- Dr. Geo http://drgeo.eu

Why? I found your take excelent. :) I was thinking of implementing it and put on a lib if it was not implemented anywhere yet.

Re: [Pharo-users] A mentoring course ComplexCondition implementation

For a different take, check out the '::' chain syntax in Cuis. It's not exactly the same as complex conditions, but it accomplishes some of the same goals. For example, [a], [b], [c] ifAllTrue: [z] becomes [a] :: and: [b] :: and: [c] ifTrue: [z] Some of the other features of complex conditions are more difficult to replicate with the chain syntax.

What are the biggest myths about Smalltalk?

by horrido

I published What are the biggest myths about Smalltalk? <https://hackernoon.com/what-are-the-biggest-myths-about-smalltalk-832a1c29f…> earlier this week. FYI, this person gave an account of his experience with Pharo <https://medium.com/@norman_kraft/i-guess-im-also-one-of-the-1-10-who-didn-t…> . Here it is, verbatim: I guess Iâm also one of the 1/10 who didnât like or âgetâ Smalltalk. I read through the same books Mortimer did, and spent a good six months trying to get even small projects in Smalltalk (Pharo) off the ground, and tried to get several of my developer friends to try out Smalltalk with me. I (and they) found little more than frustration as the reward. Packages and package management is a problem that canât simply be dismissed. Monticello is not a good package system, half the time it failed when I tried to install libraries. And the failures gave error messages that were less helpful than a Java stackdump. The IDE is a bit mysterious. I know you find it simple to work with, but many donât. There is a lot of clicking and window hopping, and I often found myself in the wrong window for what I wanted to do. There is simply too many windows in a small space and no clear tools to navigate the IDE as efficiently as other IDEs. Of course, I may be biased here: I do almost all my development in Emacs, but my friends were using IDEs like VisualStudio and NetBeans in their work and they also found the Pharo IDE clunky. Deployment is another serious issue. Deploying a Smalltalk image means installing the full image on a server and getting rights to run it. This reminds me of Common Lisp, which is a wonderful and much-loved language but is a pain to deploy in todayâs security-conscious server world. Performance was another issue. My friends and I put together a web application in Seaside with Roassal, which was kind of fun to start but a pain to finish. We wrote another one in Java to do the same task, with the D3 JS library for data visualization. The Java web application was several times faster than the Pharo app in rendering visualizations and processing data throughput. When one of the applications crashed, the difference in error and crash handling between Java and Smalltalk was vast. Smalltalk is fun to play with, but I canât think of a single secured production environment where I would use it. Maybe one day it will grow up to have bullet-proof libraries, a professional IDE and better performance but for now, itâs just a hobby language for me. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
