It’s been quite a while since I’ve posted any bitmath updates (bitmath is a Python module I wrote which simplifies many facets of interacting with file sizes in various units as python objects) . In fact, it seems that the last time I wrote about bitmath here was back in 2014 when 1.0.8 was released! So here is an update covering everything post 1.0.8 up to 1.3.0.
- A command line tool,
bitmath, you can use to do simple conversions right in your shell [docs]!
- New utility function bitmath.parse_string for parsing a human-readable string into a bitmath object
- New utility: argparse integration: bitmath.BitmathType. Allows you to specify arguments as bitmath types
- New utility: progressbar integration: bitmath.integrations.BitmathFileTransferSpeed. A more functional file transfer speed widget
- New bitmath module function: bitmath.query_device_capacity(). Create bitmath.Byte instances representing the capacity of a block device
- This my favorite enhancement
- In an upcoming blog post I’ll talk about just how cool I thought it was learning how to code this feature
- Conceptual and practical implementation topics included
- The bitmath.parse_string() function now can parse ‘octet’ based units
- New utility function: bitmath.best_prefix()
- Return an equivalent instance which uses the best human-readable prefix-unit to represent it
- This is way cooler than it may sound at the surface, I promise you
- #49 – Fix handling unicode input in the bitmath.parse_string function. Thanks drewbrew!
- #50 – Update the setup.py script to be python3.x compat. Thanks ssut!
- #55 “best_prefix for negative values”. Now bitmath.best_prefix() returns correct prefix units for negative values. Thanks mbdm!
To help with the Fedora Python3 Porting project, bitmath now comes in two variants in Fedora/EPEL repositories (BZ1282560). The Fedora and EPEL updates are now in the repos. TIP:
python2-bitmath will obsolete the
python-bitmath package. Do a
update‘ operation just to make sure you catch it.
The PyPi release has already been pushed to stable.
Back in bitmath-1.0.8 we had 150 unit tests. The latest release has almost 200! Go testing!
