Re: [Pharo-users] Iceberg for files other than code?

Hi Christopher and Tim, Thanks for your comments! I agree that managing the README from Pharo is not the most important use case, I just mentioned it because everyone know what a README is. A better example of what I want to do is Pharo's Help system. It stores the individual pages as methods th

Re: [Pharo-users] Iceberg for files other than code?

Hi Konrad - I think you can do what you describe - I think the ICeRepository entry for your project will have the path you want. And yes, its the committing back non source files where iceberg doesn’t try to do anything (and so needs help from elsewhere). Tim > On 7 Apr 2019, at 16:40, Konrad

[Pharo-users] How to catch and handle multiple exceptions

Hi - I’m wondering what the best way for handling multiple exceptions is in Pharo? It seems like we just have on:do: (where on is a single exception?). However, I think I’ve noticed that you can concatenate exceptions - so DomainError, ZnHttpUnsuccessful - and then pass that to on: However, I’

Re: [Pharo-users] How to catch and handle multiple exceptions

Thanks, I guess that makes sense, although it somehow looks a bit ugly with the nested brackets.. but nothing else springs to mind so maybe I’ll get used to it (and In my case I think it’s likely 2 or 3 different exceptions) Tim Sent from my iPhone > On 7 Apr 2019, at 20:43, Richard Sargent

Re: [Pharo-users] How to catch and handle multiple exceptions

VisualAge Smalltalk has, in addition to the standard #on:do:, #when:do:, ..., #when:do:#when:do:#when:do:#when:do:#when:do:, with the last four mapping to #whenOneOf:doMatching:, taking two arrays. It's easy enough to add your own methods like on: exn1 do: act1 on: exn2 do: act2 "An imperfect

It would really REALLY **REALLY** help if we knew what the heck you were trying to do. There is an excellent chance that it is MUCH simpler than you think. If you cannot show us the Smalltalk version of the problem, can you show us the version for some other language? On Sun, 7 Apr 2019 at 20:1

Re: [Pharo-users] difference between double dispatch and the method explains here

I can try to explain what I trying to solve. I have a Robot which can turn left,  turn right or moveForward. now I have a string like 'LAR' that means the robot needs to turn left (l) , move forward one place (A) and turn left.
