This extension provides the following facilities: - registering modules, - module resolvers, and - an API for retrieving a module instance given its name. A module is defined as a global static structure containing a pointer to a string which is the name of the module, and a pointer to a function which will be called when an instance of the module is needed. A module resolver is a function that accepts a string holding the name of the module and returns a `jerry_value_t` in an out-parameter and `true` if the module was found, or `false` if it was not. If it returns `true` and the out-parameter has the error flag set then the API will pass it through without caching. This extension provides a built-in module resolver which attempts to load modules that follow the above module definition. The API provided by this extension invokes all module resolvers it receives in sequence to attempt to resolve the name of a single module. After one resolver returns `true` and a `jerry_value_t` that represents the module the API stops iterating over the remaining resolvers and caches the value if its error flag is not set. It then returns the `jerry_value_t`. The API will return a `jerry_value_t` containing an error indicating that the module was not found if it reaches the end of the list of resolvers. The error it returns has an extra property `"moduleName"` the value of which is a string containing the name of the module that the API was asked to resolve.

JerryScript: JavaScript engine for the Internet of Things
JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.
Key characteristics of JerryScript:
- Full ECMAScript 5.1 standard compliance
- 160K binary size when compiled for ARM Thumb-2
- Heavily optimized for low memory consumption
- Written in C99 for maximum portability
- Snapshot support for precompiling JavaScript source code to byte code
- Mature C API, easy to embed in applications
Additional information can be found on our project page and Wiki.
Memory usage and Binary footprint are measured at here with real target daily.
The following table shows the latest results on the devices:
| STM32F4-Discovery |  |
|---|---|
| Raspberry Pi 2 |  |
