Since version 2.5 python-qrcode allows the direct access of the
PIL-functions. (We require version 4 and above).
Thus, we can simply call qr_img.convert() without accessing the private
member.
This refactoring is identical in functionality.
The file-printer did not automatically flush and thus behaved
differently to the other printer-classes.
Now the default behaviour is to flush after every call of _raw(). This
can be disabled by calling the file-printer with auto_flush=False.
fixes#106
The version string is in the module as __version__ available.
In the doc the version will be automatically parsed. The version comes
from the installed module if on read the docs or directly from
setuptools_scm if you are working locally.
The CLI will issue the version string if you call it with the option
'version'. The CLI does not accept commands like '--version', since this
would not be conform with the rest of the interface (and argparse).
The configuration for loading the version-string is adapted from
pimutils/vdirsyncer. It autogenerates a version string setuptools_scm at
install-time and then adds it to the __version__ member in __init__.py
I adapted the GitHub-template with a fitting comment and bumped the
changelog.
