• GoLang (http://golang.org) go version

In the process of running make, the compile scripts will set the $GOPATH envvar. If you use Go on a regular basis, this means it will temporarily override your's. Assuming you have an export GOPATH= in your .bashrc/.zshrc, this override will only last for as long as you keep this shell open.

This won't cause any problems with compilation, its just something to keep in mind.

make

./parser will parse from stdin

./parser [input file] to provide a file to parse

make clean

The parser can be provided an additional flag ./parser -extensions {input file} to enable the optional parser extensions. With these enabled, additional functionality is enabled which could cause it to fail the official test cases, but which is overall very handy for debugging and general usage. An outline of these additional features is provided below:

• Enables printing of arrays and objects inside document.write() instead of throwing an error and printing undefined.

Example: document.write([1,2,3,4]) Prints [1,2,3,4]

• Enables use of function len(v) -> int

This function provides the length of both strings and arrays. Attempting to use any other types on it will throw a type violation and return undefined. Attempting to redefine this function will succeed.
