A simple hexdump module for Python
Requires Python: >=2.6

# Simple Hexdump

A simple hexdump module for Python.

## Installation

The preferred installation method is:

```
pip install simple-hexdump
```

But you can also simply copy-paste the `hexdump` class.

## Usage

```python
# Python 2
data = "".join([chr(x) for x in range(256)])
# Python 3
data = bytes(range(256))

from hexdump import hexdump
print(hexdump(data))
```

```

## Examples

`hexdump()` accepts `str` for Python 2, and `bytes` / `bytearray` for Python 3.

```python
# Python 2
data = "hello world"
print(hexdump(data))
```

```
00000000  68 65 6c 6c 6f 20 77 6f  72 6c 64                 |hello world     |
0000000b
```

```python
# Python 3
data = b"hello world"
print(hexdump(data))
```

```
00000000  68 65 6c 6c 6f 20 77 6f  72 6c 64                 |hello world     |
0000000b
```

```python
# Python 3
data = bytearray(16)
print(hexdump(data))
```

```
00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000010
```

Other types like `array.array` need to be converted beforehand.

```python
import array
data = array.array("I", range(8))

# Python 2
print(hexdump(data.tostring()))
# Python 3
print(hexdump(data.tobytes()))
```

```
00000000  00 00 00 00 01 00 00 00  02 00 00 00 03 00 00 00  |................|
00000010  04 00 00 00 05 00 00 00  06 00 00 00 07 00 00 00  |................|
00000020
```

Calling `str()` or `repr()` will return a `str` with new lines included.

```python
# Python 3
import sys
data = b"Hello world"
print(hexdump(data), file=sys.stderr)
```

```
00000000  48 65 6c 6c 6f 20 77 6f  72 6c 64                 |Hello world     |
0000000b
```

If the lines need to be printed separately, `hexdump()` can also be iterated.

```python
# Python 3
import logging
logging.basicConfig(level=logging.DEBUG)
for line in hexdump(data):
    logging.debug(line)
```

```
DEBUG:root:00000000  48 65 6c 6c 6f 20 77 6f  72 6c 64                 |Hello world     |
DEBUG:root:0000000b
```

Repeating lines are replaced by a single asterisk to shorten the output.

```python
# Python 3
data = b"".join([bytes([x] * 0x1000) for x in range(8)])
hexdump(data)
```

```
00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

```

Finally, if data comes from a memory dump, you can specify the start address.

```python
# Python 3
data = bytes(range(256))
hexdump(data, 0xdeadb000)
```

```
