I added a bit more Dropbox API and a little demo accessing files. There is now #manipulateDemoFile: which will try to access a file called 'demo.txt' and read an id out of it. If found the file is written again, with the id increased and some other fields updated as well. If the file did not exist, it is created with id 1. All this happens automatically if you access /sso-dropbox and log in. You'll get the updated id in the web page and you'll see your Dropbox client doing a local update immediately!

Re: [Pharo-project] Future "Modules system"

by Lawson English

Well, the tools available are still relatively primitive, but bugs aside, the current version of Spoon has the capability of creating and editing methods in a "remote" spoon image using a class browser living in the main image which looks and behaves exactly like a normal Pharo/Squeak image except that it has support for Spoon and all the saving is done on the remote image. In principle, that remote image could live in your local computer or anywhere on the internet. The kind of use-cases that Craig and I have discussed include things like taking a Pharo-compatible Spoon image and "imprinting" (importing live versions of) the classes and objects from a Squeak-compatible Spoon image onto the Pharo image so that two programmers running Squeak and Pharo on their machines can collaborate on editing a specific running application in their own favorite environment. The tools and capabilities for this already exist, although there are no doubt still bugs to be squashed. A more sophisticated use-case would be to create a remote Spoon image running somewhere in the cloud that two or more programmers could manipulate at the same time. This is also doable using the current Spoon image and tools, but the traditional database issues concerning simultaneous access to the same resource apply and I don't think solving them in the Spoon Class Browser is a top priority for Craig right now.
