Recommended way to move a package

by David Pennington

I have Pharo 8.0 on my MacBookAir and Pharo 9.0 on my server. I have having lost of trouble doing what I thought would be a simple process - File out a package on one and file it in on the other but I having lo=ts of trouble - to many issues to document to be honest. So, tell me, how do I do this so that my package is in the new image along with the code extensions to other classes listed as being in the package. I can get the basic package in but the extensions never appear and I have too many to import individually. Help! David

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

esteban I would like to have a success story for the Pharo web site Could you come up with two paragraphs? And if you have a visual it would be perfect.

Re: Problem installing Seaside on Windows

by Sven Van Caekenberghe

I normally build on the server where I deploy (linux of course), but you do not have to. Pharo is cross platform. So it is perfectly possible to build your deployment image on your mac, copy it over and run it on the server. I would always advise to not save the image with running servers inside, but to use a start up script to start your server explicitly. > On 2 Apr 2021, at 19:32, David Pennington <david(a)totallyobjects.com> wrote: > > Thank you to everyone for your help.

Thank you to everyone for your help. I sorted out the public and private keys and shortened the path but it kept up with an authentication issue. I deleted everything and installed V 9.0. I shortened its name and ran the GitHub code and I now have Seaside installed and running. I now need to install STON and I can get my code working. What a great community this is!

Re: Problem installing Seaside on Windows

According to my experiences this happens if Pharo images are located deeply in the directory path. It helps if you move the image in question to some higher level. In any case, C:\Pharo should work no matter what. Seaside has lots of dependencies which are then located under its repository.

Re: Problem installing Seaside on Windows

Yes you hit the window filename length problem. Retry by creating one more pharo 8 image. Only don't take the default image name as you have taken. Change it to very short like p8-1 to keep image file name and consequently the folder name length to a minimum Then install seaside. If that doesn't work repost and we will try still another option Regards Sanjay On Fri, 2 Apr, 2021, 9:36 pm David Pennington, <david(a)totallyobjects.com> wrote: > OK, I got my software working fine on the Mac but I really need it on Windows now so I have had another go.

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

by Esteban Maringolo

I've been running a Pharo application since August last year, initially setup with everything inside a Docker swarm (database, reverse proxy and Pharo workers for the UI and REST API). I wanted to give Docker a try because I thought it was going to be "better". After having some issues with the Swarm networking affecting PostgreSQL connections [1], I ended up having a hybrid that is not the best of both worlds (I wouldn't say it's the worst either). So my summary is that unless you have several host machines, having a "swarm" is completely overkill and brings more friction than anything else. The plus of docker is that from Gitlab everytime I push a commit to master, a new docker image is created and I can update things smoothly on the server by pulling the image and upgrading the stack service. "Whenever I have time" I plan to make the reverse proxy external to docker (I currently use traefik as a container), and just keep the database and Pharo workers as docker containers. As for the stability, I only shut it down for upgrades, but in February I tried with a single VM+image serving everything (just to measure real use) and albeit it was a little slower, it handled everything perfectly [2] without a single hiccup.

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

Thanks for chipping in James - its reassuring that Iâm not overcomplicating things - however now I need to practice doing this for real - Iâve been doing individual branches for contributions reasonably fine (Iceberg does seem to trip me up from time to time - but canât quite put my finger on it) - but the next step is to practice that âcombinationâ branch and also how to keep it up to dateâ¦ thatâs the real art in all of thisâ¦ and will Iceberg help or hinder me in this activity (not to blame Iceberg - its quite a tricky concept in fairness - its just interpreting what its showing that is often the trick).

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

by Tim Mackinnon

Thanks Sanjay - you have reminded me that I have some similar notes somewhere (now located) that did the command line foo to get things running - looking at mine there was quite a big of dance to provide a way to gracefully stop and start the image so that you can easily and automatically redeploy your changes (read: use Github actions or Gitlab CI). So Iâm curious on whether Docker is now sufficiently stable stable/easy/cheap to make it a viable alternative - and whether that is also cost efficient.

With Docker options, I notice that dockerize.io <http://dockerize.io/> (not used, just a quick search) - has a micro plan for $2/m - but is 500mb ram enough (there is a $5 one for 1gm ram). Or - I stick with DigitalOcean and roll my own like before - and perhaps that has got a bit simpler. Iâm still curious what the wider community is doing.

Tim, This is a common open-source situation and what you described seems to me to be the best practice: (1) changes should be proposed as small, self-contained branches; (2) you should keep your main/master branch up-to-date with the upstream repository so that you can create new branches for new pull/merge requests; and (3) you should create your own branch with the combination of things you want to include. I donât know of a way around this.

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

by Tim Mackinnon

Hi Gabriel - appreciate your input. I too think that branches for separate features /contributions makes sense. However when you say âmerge all branches on your forkâ - is that merge them on main (master) ? But I think that would make it difficult to create your next branch for a clean feature (or am I misunderstanding?) OR perhaps you are confirming my thought that you need a combination branch in your fork that you keep merging too? Interesting that you merge on GitHub - I have submitted PRs that way (the iceberg option never seems to work for me against non Pharo remotes), but not tried merging non trivial st code in GitHub - maybe I should.

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.

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

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

by Alexandre Bergel

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? (e.g., Color red) Cheers, Alexandre > On 31 Mar 2021, at 22:01, Buenos Aires Smalltalk <github(a)fast.org.ar> wrote: > > Mole, a model for graphs, both directed and undirected. reached it's v3.2.0 version. > > Changelog > > â¢ Updated dependencies > â¢ Add Pharo 9 as a supported platform > â¢ Use GitHub actions for the build > Regards, > > The Buenos Aires Smalltalk team >
