Slightly rearranging my previous example... Object >> myTest "Object new myTest" self inform: 'test'. self halt. evaluating the comment pops up 'test' but doesn't open a debugger at the "self halt". It was working earlier today, but since then I had an episode which opened a large number of debug windows. I guess it could somehow be related. Actually its worse, Spotter doesn't show any contents, and "1 inspect" from Playground does nothing, although that does work from the old Workspace. All a bit strange. I'll move to fresh Image. I can upload this Image if someone cared to give it a once over. btw, version info...

Re: [Pharo-users] Breakpoints in Pharo
Works for me too (on windows). But sometimes, a change and accept of the current method, does not removes the "Breakpoint"-Icon. So, it looks like there is a breakpoint, but isn't anymore and the code of course does not trigger the debugger. The icon vanishes, if I unselect and select the current method. 2017-12-27 10:27 GMT+01:00 kmo: > Just tried it in Pharo 6.1 on Linux 32 bit. Breakpoints work.

Re: [Pharo-users] Breakpoints in Pharo
Just tried it in Pharo 6.1 on Linux 32 bit. Breakpoints work. So presumably this is a Pharo on Windows issue. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
Re: [Pharo-users] Breakpoints in Pharo
Ben, I don't think you can compare #halt with Breakpoints. Breakpoints have two main advantages over halts: * They do not change source code, so there is no diff between a method version with and without this debugging aid. Helps a lot, especially in times when you urgenztly need to fix a bug in production code. There's no time to read diffs that baiscally have zero meaning saturday nights at 2:00 AM... * They cannot easily be packaged into the production/runtime image, because they are not part of the source code. Thus it cannot be "forgotten" when you deploy. This is not relevant in Pharo, where there is no packaging step as in VW or VAST, but there it really is. A halt in production code makes for a great monday morning when the new version was just shipped ;-) So when you work on code to actually ship into users' hands, there are quite some good arguments for Breakpoints. There's more to them, like conditional Breakpoints that make debugging a bug so much easier and Watchpoints, but these would make my message way too long. Of course all of the above-mentioned things can be achieved using appropriate handlers for #halt and add stuff to them or make #halts just ignored at deployment time, but these are also steps that can be forgotten...

[Pharo-users] Breakpoints in Pharo
Can I expect that break points in Pharo work in the same way as in Visual Works? When I set a break point in Pharo (6.1 on Windows), it displays a red dot with an exclamation mark and when I send this message to an object, the debugger doesn't get invoked.
