UpdatedPharoByExample

by john pfersich

I found a couple of errors in SharingCode.pillar. I couldn't upload a branch. Sorry, I'm a a very infrequent github user, and I just don't get it. Anyways, lines 359 and 360 probably should be changed to this: This excludes Playground snippets, those are stored inside ''/pharo-local/play-cache'' and they can be searched using Spotter (the results https://www.dropbox.com/s/5ddtdyuq1ob6tfr/Screenshot%202018-02-25%2001.23.4…

Re: [Pharo-users] custom pre-debug window?

by Stephane Ducasse

Hi peter "hardcoded" was a motto long time ago. We have scars and stories for our grand children due to our battle against it (like SyntaxError being a Morph subclass and Scrollbar depending of Compiler.... ) ok this is less hardcoding per se. We did not the time to revisit everything yet. So if you provide a more flexible way please push it to us :).

That is not necessarily a problem, I want to add new or modified methods in remote iot applications, while Pharo is running. I'm experimenting different ways to find which one suits me best. It works with TelePharo for example, but the method has to be recompiled on the iot application side. I was just wondering if Pharo provided a way to upload an already compiled method. I will try fuel. But is fuel part of "standard" Pharo distribution? >> - dynamically change a method that is on the stack? > > have a look at on:fork: to see how igor cut some stack elements Thanks.

Tonel filetree

by Stephane Ducasse

Hi Question1: I would like to develop a new library in tonel format. Can I load and write in tonel from Pharo 60? Question2: I have chrysal in tonel and it uses property environment in filetree (I should convert but I'm scared). Is my baseline correct? Because it does not load in Pharo 60 (not tested yet in Pharo 70). baseline: spec <baseline> spec baseline: 'Containers-PropertyEnvironment' with: [ spec repository: 'github://Ducasse/Containers-PropertyEnvironment' ]. spec for: #pharo do: [ spec package: 'Containers-PropertyEnvironment'; package: 'Chrysal' with: [ spec requires: #('Containers-PropertyEnvironment') ] ]
