* Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER All feature guards of jerry-core are deciding about the inclusion or exclusion of a feature based on the state (defined or undefined) of a macro -- except for the JS parser guard, which requires `JERRY_JS_PARSER` to be defined with a value of either 0 or 1. This has some issues: - The engine cannot be built with a "clean" compiler invocation, i.e., without any `-D` command line macro definitions. This is painful for targets that must use a different build system from the project's own python/cmake-based one. - Some build systems in targets and even some code in jerry-code are already confused about the different semantics of `JERRY_JS_PARSER`, and simply define it without a value and make decisions based on the macro being simply defined or not. This patch renames the guard to `JERRY_DISABLE_JS_PARSER` and makes use of it in jerry-core based on its state, not based on its value. As obvious from the guard name, the default for the JS parser is that it is included in the build. The patch also touches those targets in the repository that explicitly defined the original macro (correctly or incorrectly). * Make cppcheck verbose Cppcheck can be quite slow sometimes, especially on Travis CI, which has a "10 mins without output means failure" rule. As the code base of the project grows, we start to undeterministically fall over that limit. Thus, this PR makes cppcheck verbose to ensure that it keeps Travis CI continuously fed with output.

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 |
