Yes, the print-it now is much better than the classic ST behavior! I appreciate the latest feature of being able to get the response as commented text. I have needed that in the past, sporadically.

It should yes Roassal2 now depends on NeoJSON by the way.

Wow, wow, wow, this is really nice. It was on my todo list to look at but I did not yet find the time, now you made it super easy and accessible.

OpenStreetMap integration

by Alexandre Bergel

Dear All, This week end I have integrated the excellent work of Onil Goubier and Thierry Goubier. They have worked on a bridge between OpenStreetMap and Roassal. As a result, you can easily decorate a map with element describing metrics and properties of geolocation. Consider the following: I think the following screenshot should be self-explanatory: Below are some results of 10lines-long scripts. Seisms during the last 30 days: Refugies monitored by the United Nations High Commissioner for Refugees: We started to write a chapter for Agile Visualization. Here it is: https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/OpenStreetM… Again, thanks Onil and Thierry. This is a very valuable contribution for the whole community!

That should be even smaller than 1K. By my count, you need fifteen objects.

The value of making it is showing that you can account for each and every bit in the result, and that's just easiest to do if you go for the least amount of code. > As Chris says, what the minimal kernel should ensure is that you can > grow it.

One explanation is that the tailoring process I use is generic and cannot anticipate whether the VM uses an object or not. That is, I start the tailoring process from an almost empty special objects array and an expression to execute. But that expression is arbitrary, it may contain a simple addition or start a seaside server. Then I ensure some objects that the VM uses directly in any execution, making ~10K of common denominator for almost any application (then 11k is ~10k of common denominator + ~1k of integer addition code ;) ). For example, I have to add the character table in the special objects array just in case a string is used in the starting-point-expression. The character table is 256 long: character table slots = 256 * 4 bytes = 1k characters = (8bytes headers + 4 bytes slot) * 256 = 3k that makes already 4k. Of course, for a simple addition you just need - a special objects array - a processor - a process - a context - the method for the context doing the addition - some SmallInteger class for the VM to check And voilÃ¡. That should be even smaller than 1K. But I lack support to detect whether the VM access directly an object or not. And adding that in the VM for a couple of kilobytes... I don't know, I have enough writing my thesis just now :). Then I have some other implementation details that make my images a bit bigger. I use for example a block to handle exceptions. I could remove that and make my object memories smaller at the cost of being less robust... In any case, the image just doing an addition is just the example that pushes the limits of *my* particular tailoring framework... But afterwards it has no other real usage :). > > Of course this is done in Pharo so it will not really be exciting for > > you. > > The minimal kernel isn't the exciting part, it's just a > prerequisite.

As Chris says, what the minimal kernel should ensure is that you can grow it. That may be through a distributed module system or another way to install code inside it. As we don't have such a module system, in our first steps we are generating a small image that contains only a compiler and a class builder. Cheers, Guille

For me, you nailed it. It makes Playgrounds even more useful.

Hi, I worked with Andrei to find a solution for improving the print-it support.
