binary_reader v1.3

Changelog:

• Added an encoding parameter in the constructer which defaults to 'utf-8'.
• Added context managers for with statement. See examples below.

The BinaryReader's buffer will get cleared after returning to the original context.

with BinaryReader() as br:
    br.write_uint32(0)

The BinaryReader will seek_to the given offset, and will return to the original position before the method was called after exiting the context.

# Position is pos
with br.seek_to(offset):
    # Position is offset
    br.read_uint32()
    # Position is offset + 4
# Position is pos

You can also use as to get a reference to the BinaryReader, if you prefer to use a different variable name inside the new context.

# Works the same way as in the previous example
with br.seek_to(offset, whence) as section:
    section.read_uint32()
