asm.js parser in C++

#cashew

Cashew is an asm.js parser written in C++.

• Cashew has a parser which does not mandate any particular AST. You can plug in your AST builder methods.
• Cashew comes with a simple AST that is similar to Uglify's AST. You can either use that, or consider it an example.
• Cashew parses ASCII input.
• Cashew is built for speed.
• Cashew does not do much in terms of error checking.

The main use case for Cashew is to quickly parse known-valid asm.js, in order to then process it.

##usage

istring.h and cpp implement an always-interned string class. This makes parsing much more efficient.

parser.h and cpp implement the parser. It is templated on the AST pointer type, and a class that provides methods to build the various things necessary.

simple_ast.h and cpp implement an AST using Cashew, and provide a builder, see ValueBuilder in the header.

test.cpp is a simple example of using Cashew and the simple AST. It is used by test.py, which runs the test suite.

##Building

Uses cmake.

mkdir build
cd build
cmake ..
make

##Testing

cd build
../test.py
