Re: And it goes on - How do I fix a missing repository

by Russ Whaley

Well, good news, bad news. I AM able to set breakpoints wherever I want in Pharo (repo) code... and in many cases the breakpoint works and the debugger pops up. However, I must have stumbled across (perhaps the only) one that blows up when I run my app. See screenshot. To be clear, I've had no issue extending Pharo repo classes (into my own packages). Besides the bold red text stating the repos are missing in Iceberg :) this is the only error I've come across. I have not spent a lot of time poking around to see which classes allow breakpoints and which don't. Initially I feared none of the breakpoints would work, but when I removed the breakpoint on SpSingleSelectionMode - the next breakpoint (in Pharo repo) did fire and brought up the debugger. I've since worked around my problem (thanks Esteban!) and the breakpoint on SpSingleSelectionMode is no longer required :) Thanks!

David, I donât think the question is whether you need breakpoints or not. You should be able to set breakpoints without these repositories.

Interesting. However, when I attempt to set a breakpoint on any code in those repos, I get a debugger failure when attempting to run my app. Iâll see if I can get a screenshot of the error message.

Re: And it goes on - How do I fix a missing repository

by Tim Mackinnon

Following this from the sidelines - I think sometimes the confusion comes from the Iceberg window showing red/detached repos that are only important if you are actively working on Pharo itself - however they âlookâ important. Iâm not sure if we have this feature request - but Iâve often thought it would be handy to have an option/checkbox to hide these âsystemâ Repos so you can focus on your own work. It should be a trivial things to add - and if it defaulted to hidden, it might reduce these kinds of questions.

I still do not understand why you need to repository at all. you should not need it to do anything of what you are trying to do (adding extensions and setting breakpoints).

hi, you can start by voyage which is an Object-Document mapper or directly with the mongo driver if you do not want to use it :) in any case, installing voyage will install also the driver and you can start there to see how it works ;) Esteban On Jun 3 2021, at 12:25 am, Russ Whaley <whaley.russ(a)gmail.com> wrote: > I am very interested in getting started with MongoDB.
