V7: Embedded JavaScript engine

NOTE: this project is deprecated in favor of https://github.com/cesanta/mjs


V7 is the smallest JavaScript engine written in C. V7 features are:

  • Cross-platform: works on anything, starting from Arduino to MS Windows
  • Small size. Compiled static size is in 40k - 120k range, RAM footprint on initialization is about 800 bytes with freeze feature, 15k without freeze feature
  • Simple and intuitive C/C++ API. It is easy to export existing C/C++ functions into JavaScript environment
  • Standard: V7 implements JavaScript 5.1
  • Usable out-of-the-box: V7 provides an auxiliary library with Hardware (SPI, UART, etc), File, Crypto, Network API
  • Source code is both ISO C and ISO C++ compliant
  • Very easy to integrate: simply copy two files: [v7.h](v7.h) and [v7.c](v7.c) into your project

V7 makes it possible to program Internet of Things (IoT) embedded devices in JavaScript. V7 is a part of the full stack Mongoose OS Platform.
