Espruino Compiler

See the Espruino Compilation Page

This project does the following:

• Turns JavaScript code into C++ (that calls into Espruino library functions for more complicated operations)
• Compiles the code with GCC
• Links and Extracts a relocatable blob of Thumb code
• Formats it into JS that can be run in Espruino

Files

• src/utils.js - general utilities
• src/infer.js - Type inferral on parse tree
• src/compile.js - Parse tree -> C++, and calling of GCC
• server.js - server that performs compilation for the Web IDE
• test.js - simple command-line test
• test_espruino.js - test in such a way that the C code is compiled into Espruino - allowing nice easy GDB debug

Setup

You need:

• A new node.js
• gcc-arm-embedded in your path
