Need help with Spec2
by Russ Whaley May 14, 2020

May 14, 2020

I've been using the Spec2-wip.pdf - dated Feb 24, 2020. Is there a newer version? I see something updated about TinyChat - but I don't know how to get that as a pdf, and I doubt TinyChat will address my issues below. I am using SpPresenter - with SpBoxLayouts for labels and buttons. (Pharo 8 stable 64bit) I've been able to figure out (in a very heavy-handed way) how to update the widgets from my model object, and when the UI refreshes (on its own) my data appears. Very good. What I can't seem to understand is, when model updates, there are times I want it to redisplay NOW - for instance, I want to display a 'saved' or 'correct' in a text field, for just a second or two, then allow the normal model update and display. In my example, I have a button with a label (SpPresenter>>newButton) label: 'ABC'. Once my model updates (with the button press action: ), the model is updated and the button label with then be 'DEF' and displays just fine. However, what I'd like to be able to do is to update the button label (or any other widget label) and have it display *immediately*... something like, the button says 'ABC', I press the button, then it says 'Correct!' (pause for a second) and then proceeds with the normal update/redisplay process where the button label then displays 'DEF'. This example is changing a label, but I'd like to also change icons, colors, etc. Clear? So I think my questions are: 1. How do I tell a particular widget to redisplay? 2. And if I can't, how can I tell the window to redisplay. 3. how can I pause (very short - just to let the temporary change be visible for a short time) and then allow the normal processing continue - resetting labels, icons, colors, etc. (I'm using '1 seconds asDelay wait.') 4. and since I've been talking about buttons - SpButtonPresenter - I don't see how to control width and height - all the way up through the hierarchy. If buttons share a layout (SpBoxLayout) row or column, those are all the same size (although I can't seem to control that sizing). Buttons in the next layout>row - are huge. I'd like to be able to set their size specifically (then I can work on making them relative to the extent later). Thanks for listening. -- Russ Whaley whaley.russ(a)gmail.com

Uptime
by Sven Van Caekenberghe May 14, 2020

Hi, So here is a little anecdote from the real world. I was planning to update the OS on my Linux server, from Ubuntu 18.04 LTS to 20.04 LTS (Long Term Support). This small (Digital Ocean, 1GB RAM, 1 Core) cloud server runs 3 Pharo images with public facing web sites. The machine itself reports: $ uptime 12:37:50 up 530 days, 21:46, 1 user, load average: 0.02, 0.04, 0.01 which means it hasn't been powered down or didn't restart in 530 days. I was surprised to discover that 2 of the Pharo images on that machine did just as well: $ ./repl.sh Connecting to Telnet REPL at locahost:41011 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo-7.0+alpha.build.660.sha.2eb9bd2f41e7b0bd8f9f4190906910f83c178ab1 (32 Bit) pharo> get system.uptime 405 days 20 hours 29 minutes pharo> quit Bye! $ ./repl.sh Connecting to Telnet REPL at locahost:41001 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo4.0 of 18 March 2013 update 40620 > get system.uptime 530 days 21 hours 44 minutes > quit Bye! So both Pharo 7 and Pharo 4 kept on doing their jobs for a very long time. I think this is a testament to the stability of Pharo and to what is possible.

Well, you can capture the stack to the clipboard, and you can save it as a 'Fuel' file. That allows examination (including by others, within a different image). If you look at the image you posted, of the debugger window, on the far right of "Proceed Restart Into Over Through" there's a small drop-down menu (with an icon of horizontal bars). Click on that and you should see options for 'Fuel out Stack' and 'Copy Stack to Clipboard'. As far as how to make the best use of this... That's over my head! (But others on this forum know.) -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

git and Pharo new book...

ï»¿ ï»¿I think we just jumped threads. Iâm still getting familiar with using this list. CÃ©drick just posted this I think in response to my exception report: http://forum.world.st/file/t372658/Screen_Shot_2020-05-12_at_2.png > I just had a quick look. This is cool. > I might be missing a use case where I dit a previous fork and I want to use it later in time. I think thatâs nice to cover this use case. Do you sync your fork on github ? From iceberg ? Or maybe no sync is possible ? > > Cheers, > Cedrick > Assuming that is true here is my response: I have not done any syncing yet. I created an empty github repository and was trying to add that to Iceberg when this exception. There is virtually nothing in my github repo: Https://github.com/MichaelKentBurns/FredsLunch-Pharo-iceberg âtrying to use iceberg to coordinate with GitHub repositoryâ

Hi, Your document is definitely out of date! The current version of PBE for version 5, 6, and 7 can be found here: https://github.com/SquareBracketAssociates/UpdatedPharoByExample/releases If you're using Pharo 8 or 9, you'll want the updated version, PBE8, which can be found here: https://github.com/SquareBracketAssociates/PharoByExample80/releases Yes, you can FileOut and FileIn. If you right-click on an item in the System Browser (which was 'Nautilus' until version 7, when it was replaced with 'Calypso'), the last fly-out menu has 'FileOut' listed. (I think you need to send a message in the Playground to use 'FileIn'; I'm not sure, as, like most, I don't use it.) Note that you can no longer (or "shouldn't") use SmalltalkHub; it's deprecated, and if it's not already locked for modifications, it will be shortly. (Then it becomes read-only until late in the year, when the site will be shut down.) So you *should* use GitHub. Since version 7, it's the default repository for Pharo code. There is now a native Git client in Pharo called "Iceberg". It works with GitHub, GitLab, BitBucket, local git repos, and remote git repos. You can create git repos, commit/push/pull, submit PRs, etc. from Iceberg while remaining in the Pharo IDE. You can read more about Iceberg and managing code here: https://github.com/SquareBracketAssociates/Booklet-ManagingCode/releases Have fun! -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Sorry about that... You should end up on a GitHub "Releases" page for each document. In the section for the top-most release, you should see an "> Assets (3)" control. Click the arrow to open it. It should then list a PDF, a ZIP, and a '.tar.gz' document. You probably want the PDF, which you can read on the screen and/or print out. Download the document to your system by clicking on its link. -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Also, regarding keeping your images under control, if you haven't downloaded and started using Pharo Launcher, you should! It's a fabulous tool... http://pharo.org/download -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Need help putting my Pharo package under source control
by Michael Burns May 11, 2020

May 11, 2020

I read the section in 2018-09-29-UPDATEDPHAROBYEXAMPLE: "Monticello packagesâ just after Figure 3-27 I have a smalltalkhub account and created a repository: MCHttpRepository location: 'http://smalltalkhub.com/mc/MichaelKentBurns/FredsLunch/main' user: '' password: â' In Pharo I registered this as a new smalltalkhub repository: 'http://smalltalkhub.com/mc/MichaelKentBurns/FredsLunch/mainâ And it shows up in the repository list for my package. Then I think Iâm supposed to poke âSaveâ. It was kind of sketchy and popped up exception dialogs while I was typing my comment, but eventually it worked. I was able to download the resultant .mcz file and unzip it, then change the ^M to newlines to get a readable source. Iâm not really happy about this process. I would like to actually save this into my GitHub repository. The document mentioned at the top mentions using git, but just says: There is a chapter in preparation on how to use Git with Pharo. Request it on the Pharo mailing list. Question 1: Is there such a document? If so, can you point me to it? Question 2: Is there a way to fileOut a class, or a package?

ZincStaticServerAdaptor starts with different port
by Esteban Maringolo May 10, 2020

May 10, 2020

Hi, I have a ZnZincStaticServerAdaptor, that after quitting the image and starting it again starts in a different port. So I did: WAServerManager default adaptors do: [ :each | WAServerManager default unregister: each ]. (ZnZincStaticServerAdaptor startOn: 8000 andServeFilesFrom: (FileLocator imageDirectory / 'static' ) asFileReference). And get the server running in the port 8000. [see zn8000.png] But after restarting the image, it is running in the port 80. [see zn80.png] Why is it so? Regards,
