Force conversion unit in format_size

[sebastian-luna-valero]

Hi,

We are interested in adding an optional flag to format_size() so you can force the conversion unit.

Here is the desired behaviour:

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4))"
4 GB

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4, force_unit='bytes'))"
4000000000 bytes

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4, force_unit='KB'))"
4000000 KB

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4, force_unit='MB'))"
4000 MB

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4, force_unit='GB'))"
4 GB

python3 -c "import humanfriendly; print(humanfriendly.format_size(1000 ** 3 * 4, force_unit='TB'))"
0 TB

Best regards,
Sebastian

Hi @xolox

All tests are passing except for coveralls which I don't know how to fix.

Please have a look and let me know your thoughts.

Many thanks,
Sebastian

Hi again,

Alright so adding tests for the new code solves the coveralls issue.

Please have a look and let me know your thoughts.

Best regards,
Sebastian

any news on this?
its exactly what im looking for

Hi,

Probably my changes are a bit too much for this package and that's why it hasn't been merge.

I have just taken the relevant code out and copied it to my own script. @yodog I recommend you to do the same.

If you think it is interesting, I might upload it to my own git repo and share it with you.

Best regards,
Sebastian
