Lua Scripting Language |
 |
|
 Lua is an advanced programming language, offered to Open AT® developers as a complement to the standard C-based ADL interface. This is the first public alpha release of the Open AT® -Lua plug-in.
Provided as a regular Open AT® plug-in, the Lua compiler, virtual machine, library and interactive shell simplifies the development by taking care of many tasks usually left to the developer in C-based development environments, including memory, data flow, and control flow management.
More specifically, it provides:
- All the features you should expect from a high level language:
Unlimited multithreading and synchronization, advanced data structures, proper string handling (including regular expressions), automatic memory management (continuous M&S garbage collector), first-class functions, modular and object-oriented programming...
- Streamlined development environment:
You control the WCPU through a standard telnet client, and it automatically uploads and runs your program files from any standard FTP server: no compilation time, no explicit download process, no mandatory reboot between code modifications; only standard, interchangeable tools and protocols.
- Interaction through the telnet shell:
You can inspect, control and update any module's state, anywhere in the world, as soon as it's connected to the web: switch tasks between foreground and background, create, alter or kill resources (sockets, bearers, tasks, RAM data, flash objects...). This dramatically eases prototyping, development and maintenance of your applications.
- Live code update:
You can change function implementations, live, without rebooting nor even stopping the WCPU. Whenever a new implementation suits you, you can instantly save it to flash.
- Remote debugging over TCP/IP:
What you used to do with a module sitting on your desk, you can do with a module anywhere in the world.
- Every API that ought to be blocking is blocking:
Thanks to dynamic multithreading and synchronization, you keep full access to the event-driven model whenever it suits you best, and can mix the two approaches as you wish.
- Complete mapping of ADL, WIP and AT features.
- Easy binding with C:
Because C is here to stay, especially in embedded software: you write the realtime parts of your application in C, while the remaining 90% stay in a high-level, maintainable language.
- The language is very easy to learn:
Provided with proper docs, a proficient developer will master most "normal" Lua programming technics and idioms in about an hour. Advanced features remain available for those who need to go further.
