Pharo Sprint in Lviv

by Oleksandr Zaytsev

Hello! Today in Lviv (Ukraine) we had our first local Pharo Sprint. There were three participants - students of different universities. The whole event lasted for about 4 hours. In that time we have resolved one simple fix case and three review cases and reported one issue with Monticello. It's not much, but this was our first time contributing to Pharo. And the experience was very educating. Big thanks to everyone who helped us! We will be holding Pharo Sprint in Lviv every two weeks (so the next time will be on May 21). We also have a monthly event called "Beer & Smalltalk" where we talk about our projects and discuss some cool ideas. If you live nearby and have an interest in Pharo - join us.

Re: [Pharo-users] Pharo Audio?

it tried the latest VM for Pharo6 and it works. you need to install "osspd". anyway, any code snippets around, that shows me how to load and play mp3, ogg or wav?

Editor with syntax highlighting awareness

by phil＠highoctane.be

I want to do such an editor. Preferrably something fast. And in the current Pharo. There have been several text models, Rubric etc. What is the quickest way to get such a thing? Features: Load/Save content Highlight keywords based on syntax parsing Act on the element under the cursor Act on the element when (modifier)clicking on it (or hovering). Fast (or at least, not sluggish on a "normal" (ie Core i5 1.8Ghz) laptop) This is really something I miss being able to do in Pharo. Lots of code is using "STHStyler" things but there seems to be no easy way to extend that (as it seems to be using the AST or something like that). I am okay with a first easy approach to highlighting, like in Vim where one puts a syntax file with not that many things. Phil

Yes, you need to install PharoSound from the Catalog Browser (World Menu -> Tools -> Catalog Browser).
