Pharo 6.1 debugger - suggestions break once, does funny things?

by Tim Mackinnon

While Iâm on a debugger tripâ¦ anyone else also notice that the Suggestions, Break once debug option acts weirdly? I seem to get a debugger but it halts several lines after where I have said, and if I start stepping the debugger seems to jump to funny places and show values that donât line up with what I know is happening? If I use Suggestions, Break it seems to work correctly (apart from the Step Through I mentioned in another thread). Tim

PlotMorph on Pharo 6.1

by st＠bestley.co.uk

I downloaded 64bit Pharo from <http://files.pharo.org/platform/Pharo6.1-64-mac.zip> Started it and first thing opend Catalog Browser. I searched for plot Chose pLotMorph and chose Install Stable Version I got an Information window saying There was an error trying to install PlotMorph. Installation was cancelled. So 1) Does PlotMorph work as it is in the SystemCatalog I assume so. So how shoulkd I load it? 2) How can I see what the error actuially was 3) How can I actually capure the popup window to cut and paste the error. -- Mark

Pharo 6.1 debugger - doesn't always step/step through reliably?

by Tim Mackinnon

Has anyone else noticed that if you are stepping through code - the into and through operations donât always step into or step through? Iâve been debugging some RBParser code to understand how it works and I notice that when I try to step through #intersectsInterval: anInterval in the chains of nodes it alway skips going into methods when its looping through a collection (and its not the first loop through, but the second one where the debugger just stops over and not into). I canât find a very specific example - but thought I would see if this is a known issue or whether possibly I am doing something wrong? Iâm assuming that when faced with looping through a collection of children, its normal to use âthroughâ to get into the iteration block, and then once inside I can use âintoâ to then step into a method that each child is calling. As I said, it works the first time, but the second time (when I find I have to click âthroughâagain to get into the block for the next child, its then when âintoâ just doesnât seem to cooperate? One possibility - are getter methods optimised - as in for a method #size, if it simply returns an iVar - does the debugger not step into those? Tim P.s. while taking about the debugger - does anyone else find the current keyboard shortcuts for over, into, through a real nuisance? They arenât consistent between all 3, or easily pressable e.g. Into = cmd+e, over = cmd+shift+o, cmd+shift+t I donât mind holding cmd-shift with my left hand, but then my right hand should have keys close to each other for these operations (like I, o, p - and yes p doesnât quite match âthrough", but its conveniently in order to let you quickly step through lots of code.

Good luck because this is heavy after a while. I'm finishing a first full version of the book for the prague lecture as well as all the slides (done) now working on exercises.... tedious because also a long term effort.

Thanks Stef for your support. I have already added you in the private repository "GCI-2017-with-Pharo", as we need to keep prospective students away from the task list before the program begins ð Looking forward to more ideas on the task list. Thanks a lot. Best Jigyasa Grover -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Following migrations like this is never easy/elegant.
