Function Documentation

def setuptools.depends._iter_code (   code )

private

Yield '(op,arg)' pair for each operation in code object 'code'

def setuptools.depends.extract_constant	(		code,
			symbol,
			default = -1
	)

Extract the constant value of 'symbol' from 'code'

If the name 'symbol' is bound to a constant value by the Python code
object 'code', return that value.  If 'symbol' is bound to an expression,
return 'default'.  Otherwise, return 'None'.

Return value is based on the first assignment to 'symbol'.  'symbol' must
be a global, or at least a non-"fast" local in the code block.  That is,
only 'STORE_NAME' and 'STORE_GLOBAL' opcodes are checked, and 'symbol'
must be present in 'code.co_names'.

def setuptools.depends.find_module	(		module,
			paths = None
	)

Just like 'imp.find_module()', but with package support

def setuptools.depends.get_module_constant	(		module,
			symbol,
			default = -1,
			paths = None
	)

Find 'module' by searching 'paths', and extract 'symbol'

Return 'None' if 'module' does not exist on 'paths', or it does not define
'symbol'.  If the module defines 'symbol' as a constant, return the
constant.  Otherwise, return 'default'.
