New issue 10 by rich...@bucker.net: Value error while parsing a bitmap with
\x20
http://code.google.com/p/iso8583py/issues/detail?id=10

Here is the 0820 message that I generated. Notice that I omitted the length
and that the first 4 bytes are the MTI. (this string wear produced with
pprint().

'0820\x82
\x00\x00\x00\x00\x00\x00\x04\x00\x00\x00\x10\x00\x00\x0002171704580315633010825000344'

It's not interesting to note that the 6th-byte of the message or the
2nd-byte of the bitmap field resolved to a \x20 or a space.

when __getBitmapFromStr() attempted to parse the first byte in this code:

if (int(bitmap[0:2],16) & self._BIT_POSITION_1) .....

I receive a value error because int() does not like the space in the
string. For example try these:

int("\x82\x20")
int("\x82 ")

They are the same value and they both generate the error. I think you
should consider using the struct.unpack() instead of int().

btw: don't panic but the message will not parse completely in ISO8583. The
message spec is 8583-like but that's it.

Hi, Did you generate this ISO8583 whith the ISO8583py library?

Or are trying to parse a 8583-like with the library?

Seems that this project expects the bitmap in binary coded hexidecimal?

The spec I'm coding to is strict binary.

Thank for the information.
This library expects 100% ASCII values, So you cannot parse this kind of
ISO8583-like package without change the source code.
Work with Binary Data (Bitmap and bits) are in the TODO list.
I'll close this issue because isn't a Bug, but a request for feature.
Best regards,
