Wallaroo library has been used in real-world projects since its early releases, some years ago. Of course, I was the first to use wallaroo to develop industrial projects (i.e., telecommunication software currently running in a large number of devices). But then, I had a lot of feedback from other developers, and I know for sure that wallaroo is running in many embedded devices and custom servers.
Lately, a nice guy from Samsung has been so kind to inform me that a family of their products is using Wallaroo. The Samsung refrigerator Samsung Family Hub has its "Fridge Manager Application" powered by an internal library that uses Wallaroo to manage the dependencies among internal components.
The email exchange with this guy has been extremely valuable: in addition to making myself clear that Wallaroo needs to keep on supporting older C++ standard (let's say pre C++11), it turned out that Wallaroo is not powerful enough when it comes to managing multiple catalogs through wiring files. Indeed, a file can be used to fill a catalog, but wiring files are not aware of catalogs altogether.
I'm gonna discuss the catalog problem in a future post. For now, I'd just like to say thanks to everyone who's using Wallaroo in whatever project: feel free to send me an email or add a comment to this post so that I can learn what features would you like to see on Wallaroo.
