bytegapbuffer 0.9.4

Installation

Installation is via pip. To install the latest release version:

$ pip install bytegapbuffer

To install the current development version from git:

$ pip install git+https://github.com/rjw57/bytegapbuffer

Usage

The bytegapbuffer collection aims to behave just like a bytearray. For example:

from bytegapbuffer import bytegapbuffer

a = bytegapbuffer(b'hello')
a.insert(3, 65)
a.insert(4, 66)
assert a == b'helABlo'

Status

This project is used as part of a personal project of mine and, as such, implements just enough of the sequence, mutable sequence and bytearray interface for my needs. Pull requests adding missing functionality are welcome. Please also add a test for the functionality.

Current features:

• Retrieving element(s) via [i], [i:j] and [i:j:k] style slicing.

• Deletion of element(s) via [i], [i:j] style slicing.

• Insertion/replacement of element(s) via [i], [i:j] style slicing.

• Insertion of element via insert().

• Length query via len().

• Sub-sequence search via index() and find() methods.

• Equality (and inequality) testing.

• Iteration over contents.

• Efficient codedstring wrapper allowing bytegapbuffer to be used as underlying storage in a text editor.

All of the above should work exactly as the bytearray object does. (This is tested in the test suite.) Additional non-bytearray features:

• Deep copying via copy() method.

Test suite

The test suite may be run via the tox utility. The Travis builds are set up to run the test suite on the latest released Python 2 and Python 3 versions.
