Re: Understanding how to best structure branches to contribute to a 3rd party project

by Gabriel Cotelli

Hi Tim. I prefer to have individual branches for each feature or bug because it eases the review process for the original project. You can merge all this branches in your fork if you need it together before they are merged upstream. Unless one feature depend on other one. I usually do the merge using PRs on GitHub via the web interface or using the git command line client and didn't find too much problems so far.

Re: [ANN] Mole v3.2.0 [v3.2.0] released!

by Gabriel Cotelli

If I understand your question properly, without creating the graph that model the relationship between the objects involved the answer is no. I have to review the traversal algorithms to see if it is feasible to avoid creating the graph.

Whats the easiest/cheapest way to run a Pharo web app in 2021?

by Tim Mackinnon

Hi everyone - its been a few year since I last hosted a little Pharo web app - and the last time I did, Sven pointed me to DigitalOcean and creating a tiny instance and configuring an Ubuntu server and then copying a pharo image on to that. It recall it wasnât too bad, albeit a bit fiddlyâ¦ Now several years later - I canât recall the exact steps, and vaguely recall there was something about 32bit vs 64bit setup etc - but am wondering if things have advanced a bit and whether its much simpler these days? Iâve seen references to Docker images for Pharo, and am wondering if now that is a prime time way to easily get a small demo application up and running with minimal fuss. Does anyone have advice - or something to point me to? Ideally I want to hook something up in Gitlab CI do deploy to this thing automatically (this is where I got to a few years ago - but in picking things back up I am hoping this has all got much simpler).

Re: Roassal3 Popups

by Alexandre Bergel

Dear Evan, Welcome back! Yes, we moved to Roassal3, and as you may have experienced, not all the features of Roassal2 have been migrated to Roassal3. Currently, popup in charts are still work in progress. However, you can have something that should do what you expect using: -=-=-=-=-=-=-=-= chart := RSChart new. classes := Collection withAllSubclasses. dataX := classes collect: #numberOfMethods. dataY := classes collect: #numberOfLinesOfCode. plot := RSScatterPlot new x: dataX y: dataY. plot processBlock: [ :shapes | shapes doWithIndex: [ :shape :index | shape model: (classes at: index). shape @ (RSPopup text: 'My data: ', (classes at: index) asString) ] ]. chart addPlot: plot. chart xlabel: 'number of methods'. chart ylabel: 'number of lines of code'. chart -=-=-=-=-=-=-=-= However, be aware that this code may soon not work anymore. In particular, we plan to remove the processBlock: method and replace by something else. Let us know how it goes Cheers, Alexandre > On 31 Mar 2021, at 05:37, Evan Donahue <emdonahu(a)gmail.com> wrote: > > Hello, > > Just returning to Pharo after 1000 years and have discovered that Roassal has upgraded to Roassal3.

How to get top level menu item shortcuts to work?

by Tim Mackinnon

Hi - I tried asking this on Discord, but it got lost in the day to day stuff - so trying here. I am a bit confused how Keyboard shortcuts work in P8 for World menus. I have a method with the <worldMenu> pragma, and I get aBuilder, and I create a top level menu item. Then to add a child, it seems that I just create a new #item: and set its #parent: to the new id I've created (all good), and then I set #keyText: 'r, o' and while it shows a menu item with CMD-RO in its text, the keystroke doesn't seem to work. I've tried different options even, 'o, x' but none of them trigger - so I must be missing something? Anyone know? My code looks like this (menuId = #Paradise - the top level menu item I have created) | menuId | (aBuilder item: (menuId := #Paradise)) order: 4.0; target: self; help: 'Tools to support Code Paradise projects'. (aBuilder item: #'Reload...') parent: menuId; help: 'Clear the session for a web application, and reload its''s page'; order: 15; keyText: 'r, r'; icon: (self iconNamed: #smallUpdate); action: [ self resetSession ].

Understanding how to best structure branches to contribute to a 3rd party project

by Tim Mackinnon

Hi Everyone - I tried asking this on Discord, but I think it got a bit lost - and perhaps for more philosophical questions, here is better. So - Iâm wondering what is the recommended way to work with another project you want to contribute to (in my case CodeParasides). So I know I can fork it and put the fork in my baseline. But Iâm assuming contributions are best done discretely on a branch per proposal (this seems to be the Pharo way - and it makes sense for ease of understanding), but if you have a few of these contributions in play (while the maintainer is evaluating them) would you then have your own âcombinationâ branch to consolidate all those fixes until they get merged in? Iâve started to try this, but merging between branches gets a bit tricky - a few times now it seems that Iceberg shows me misleading info on what is being added/removed (it always looks like my changes are going to be removed, when if fact they get added - so its a bit of a leap of faith on this). So Iâm wondering if Iâm overcomplicating things - or whether this is the suggested way to work with another project? Tim

Hello, That is awesome! I looked at the documentation, but I am left with one question: - is there a way to run a graph traversal algorithm on any arbitrary object?
