Russ, Here's a link; I created a GitHub gist in your honor: https://gist.github.com/tbrunz/4209026fabc44c5baf0a502f677b708c Please provide comments, improvements, corrections, or anything that will make it clearer for others who are in the same boat.

Hi Russ, Here's how to submit a bug report. Fortunately, GitHub makes it easy and straightforward. Surf to https://github.com/pharo-project and find the particular project that's affected. I think in your case, you want "pharo": https://github.com/pharo-project/pharo Underneath "pharo-project/pharo" you'll see 7 links in a toolbar. Click on "Issues", which brings you here: https://github.com/pharo-project/pharo/issues On the right is a big green button, "New issue". Click that to get a bug entry form. You have a bug, so click the "Get started" button for "Bug report". Choose a good title, nicely worded, to be nice to the devs so they can get a good idea from just a glance. Short & sweet. (They prefer 50 characters or less, because your title becomes an email "Subject:" line.) There's a template bug report that tells you what they need from you. You can edit it or replace it with your bug report. Markdown is supported (and can help with readability). A "cheat sheet" is here: https://guides.github.com/pdfs/markdown-cheatsheet-online.pdf and a more detailed explanation is here: https://guides.github.com/features/mastering-markdown/ The toolbar above the text area will apply the most-commonly-used markdown for you, with just a button click. Select text, click the associated button. You can click the "Preview" button to see how your markdown will be rendered in the submitted report; click on "Write" to return to the editable version you started with. Note that you can attached code, files, images, etc. to help explain. Just drag files into the text area of your report and they'll automagically be attached for you. Similarly, you can click where it says, "Attach files by dragging & dropping, selecting or pasting them" and it will open a file browser for you to point-and-click. When you're done, click "Submit new issue". That it! -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I found the same problem only yesterday when I tried "Extract method" in Pharo 8 (for the first time). Comprehensive UI tests would be a great thing. But complicated to create. Like writing tutorials for GUI-based applications. ;^) Is there a way to emulate a GUI user and the actions of mouse moves & clicks (as well as keypresses)? And to capture the results of pointing, clicking, right-click menu selections, etc? Is there a UI testing framework for Pharo that includes this? If not, should we start building one? How much of the above is tied directly to Spec2 and how much is part of the core elements of Pharo? -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Intermediate-Level Tutorials for Pharo

by Russ Whaley

EXACTLY!, StÃ©phane, thank you! I will go through this tutorial today. Has anyone written any documentation or maybe a tool that would help understand what each âwidgetâ is capable of? I review all example code, read all class comments and peruse the class hierarchy, but when a widget capability doesnât work for me, I donât know whether Iâm using it incorrectly, in the wrong place, or if itâs a bug.. I.e filter/sort, TransmitTo:, drag and drop, double-click, right-click, presenter management (modal, etc), and how to force the display to refresh, etc. Your thoughts? I appreciate (and admire) all the work you and everyone put into the documentation and tutorials - and I am voracious in consuming them. I hope to build my skills to be able to contribute for the community. Thanks!
