meta_unpack [function]

meta_unpack( string bytecode_buffer )

parse a bytecode buffer

• returns a dict containing root function or false/warning on failure

The structure of a function:

• array consts -- contains a list of parsed constants for the function
• array code -- contains a list of parsed instructions for the function
• array lines -- contains a list of line numbers for the instructions, array size should be equal to that of instruction array
• bool gotthis -- whether this is required (should be false for root function)
• int numargs -- number of input arguments (should be 0 for root function)
• int numtmp -- number of temporary variables in function
• int numclsr -- number of closures required in function
• int inclsr -- number of incoming closures (not generated by the function)
• string name -- name of the function ("<main>" for root function)
• int line -- first line number of function definition (0 for root function)

The structure of a constant:

• int type -- base type ID of constant, should be one of SVT_[NULL|BOOL|INT|REAL|STRING|FUNC]
• var data -- variable in the previously specified type or a parsed function in the case of SVT_FUNC

The structure of an instruction:

• int op -- operation code (ID), one of SI_ constants, name can be retrieved with meta_opname
• int a -- the "A" argument, 0 - 255
• int b -- the "B" argument, -256 - 255
• int c -- the "C" argument, -256 - 255
• int e -- the "E" (extended) argument, -65536 - 65535 (occupies same memory space as A/B)
