'''
for tests that need to test long values in python 2
python 3 does not differentiate between long and int
and does not supply a long keyword
instead of testing longs by using values such as 10L
test writters should do this:
from compathelper import _long
_long(10)
'''
_long = int
'''
for tests that need to test string values in python 2
python 3 does differentiate between str and bytes
and does not supply a basestring keyword
any tests that use basestring should do this:
from compathelper import _basestring
isinstance(_basestring, "hello")
'''
_basestring = str
'''
for tests that need to write to intefaces that take bytes in
python 3
python 3 has a seperate bytes type for low level functions like os.write
python 2 treats these as strings
any tests that need to write a string of bytes should do something like
this:
from compathelper import _bytes
os.write(_bytes("hello"))
'''
_bytes = lambda s: s.encode()
'''
for tests that need to write to intefaces that take unicode in
python 2
python 3 strings are unicode encoded as UTF-8 so the unicode object
doesn't exist
python 2 differs between a string an unicode string and you must specify
an encoding. This macro will specify UTF-8 in python 2
any tests that need to use unicode should do this
from compathelper import _unicode
unicode_string = _unicode('this is a unicode string')
'''
_unicode = lambda s: str(s)
_unichr = chr
else:
_long = long
_basestring = basestring
_bytes = str
_unicode = lambda s: unicode(s, 'UTF-8')
_unichr = unichr
