Pharo-Sound

by Russ Whaley

I'm using Pharo 8 stable (64bit) version. I pulled PharoSound from the Catalog and installed. Installed fine, no errors. I went to the comments on the abstract class. Copied the examples to the Playground, ran them - worked fine (although I don't know how to stop the dang PluckedString example!!)... I digress :) I created my own subclass to play specific sounds at certain events in my application. Worked well. A day later - I have no sound in my image at all now. Nothing works. I reinstalled from the Catalog. Ran the code listed in the AbstractSound comments - nothing. I installed a new Pharo 8 stable 64-bit image - pulled PharoSound in, copied the sampe code from AbstractSound comments... and it worked just fine. Any ideas how I can get sound to work again on my original image? For me, it is a real pain to try and migrate all my code over to a new image. It is apparently a character flaw on my part, but it takes me hours to get Git/Iceberg working properly on a new image. (yes, I'm ashamed). I see a new book on the topic, but I had been following that book while it was wip, and Git/Iceberg just whips my butt. But if going to a new image is the solution, I'll try, try again. What do you think? Thanks, Russ -- Russ Whaley whaley.russ(a)gmail.com

Need help with Spec2

by Russ Whaley

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

I created an empty github repository and was trying to add that to Iceberg when this exception.

by Offray Vladimir Luna CÃ¡rdenas

Hi, This is perfect timing, as I have started to slowly migrate my own repos from SmalltalkHub to aÂ simple, self hosted and self contained Gitea[1] instance, as I don't "commit" to the dangerous logic of hyper centralization that being mainly where everybody is (GitHub, Facebook, Gmail, etc).Â Knowing Iceberg and its rationale is an important step to use improved DVCS for the community and maybe at some point, add support for things like Fossil (and, hopefully be able to help with that). [1] https://gitea.io/ Thanks a lot, Guille, Steph, Allex, and all the community that makes this possible.

Hi, I couldn't resist: https://github.com/svenvc/zinc/commit/264cbd3160f665f776232c02d013ce533df18… This is based on your core idea, but adds an html/page/form to shorten URLs which can also be used programmatically. There are also some functional tests.

Basically, here is the full playground I did with them (so in 10 minutes), doing a manipulation each line (the script was done gradually from halt) : I doing it a server delegate lie the ZnImageExampleDelegate with a new dict each time the server is started.

Re: [Pharo-users] Code completion in blocks (Pharo8)

Hi Davide, Iâm not sure if that works on Pharo8. Could you try quickly Pharo9 to see if thatâs fixed there? Iâve made a pass on the code completion there..
