Re: [Pharo-users] Behold Pharo: The Modern Smalltalk

by Dimitris Chloupis

for me it is a yes and no situation, yes its very coold to have your entire system in your fingertips but Pharo has serious issues with code organisation and I find the lack of namespaces quite inconvenient. You have to be careful how to name your classes which does not sound to me very OOP friendly. Also the IDE does not handle spaggetification very well, sure you can find implementors , senders etc but if the execution chain is complex , welcome to spaggeti hell. But that is a problem with most other IDEs if not all as well. Problem is in this case that we have the very good rule of using sort methods which multiplies this problem and makes navigation even harder. Code becomes much easier to read per method and messages but much harder to understand in a bird eye view. Some of that pain has been aleviated with the introduction of GTSpotter which I have praised quite a lot and I will continue to do so. But yeah there are more needed to be done in the department to make Pharo code navigation a more comfortable task.

I dunno, maybe Iâm weird, but I find the System Browser a fantastic way to explore the class library. If you find a class or method that isnât well documented, write a comment and send a change request. Stef told me this ages ago. I might add, if you find a bug you should write a test that exercises the bug and submit it on fogbugz (the bug tracking system). I will reference of response of mine to a similar opinion made by Richard: https://medium.com/@vitormcruz/i-disagree-it-is-much-harder-to-find-anythin… My 2 cents.

Re: [Pharo-users] [Ann] PharoLauncher v1.0.1 released!

Hi Christophe, Yes, but: 1- I canât execute it if I donât have administrative rights â I have tried with the provided link. Before I get to the installation directory choice, windows prompt me an error telling me I must be an admin. It is probably some windows policy for all exe files, I know it is possible to bypass this as some applications do (Intellij for example), but it is usually easier to provide a zip; [image: Inline image 1] 2- 7-Zip can open this executable as it were a zip file, thatâs how I manage to install Pharo Launcher.
