Method Detail

run

public static VaporProgram run(Reader input,
                               int line,
                               int col,
                               Iterable<VBuiltIn.Op> ops,
                               boolean allowLocals,
                               String[] registers,
                               boolean allowStack)
                        throws IOException,
                               ProblemException

Run the parser on the given input. Returns an AST of the program.

Parameters:

input - The input source.

line - The line number the input starts at (typically 1)

col - The column number the input starts at (typically 1)

ops - The list of built-in operations the program is allowed to use. For example: VBuiltIn.Op.Add.

allowLocals - Whether the program is allowed to use local variables.

registers - The set of global registers the program is allowed to use. Setting this to 'null' means registers are not allowed.

allowStack - Whether the program is allowed to use the stack explicitly.

Throws:

IOException - If there's an I/O error when reading from the input source.

ProblemException - If there's a syntax error in the input.
