drop support for Python 2.x as it is very much EOL

2026-02-02T07:22:15Z

A follow-up to b96a5ad562deffa697d966c29546650aae645f48 where we stopped having CI run tests on Python 2.x. This actually drops the few remaining Python 2.x compatibility bits as Python 2.x has EOL'd a long time ago. Signed-off-by: Benjamin Cabé Signed-off-by: Torsten Rasmussen

Use 'python3' instead of 'python' in hashbangs

2020-01-24T20:33:47Z

It's not obligatory for distributions to have a 'python' binary these days, but 'python3' is likely to be available: https://www.python.org/dev/peps/pep-0394/#for-python-runtime-distributors. Change all hashbangs to point to 'python3'. This will break running $ ./script.py on *nix systems that don't have a 'python3' executable. Changing it to $ python script.py is pretty painless at least. This change won't break Python 2 when installing via 'pip', because entry_points creates bounce scripts with their own hashbangs. The major version will be increased, in case someone looks at the major version but doesn't install via 'pip'. Fixes: #89

Catch EnvironmentError instead of OSError/IOError

2019-07-01T22:03:02Z

menuconfig.py tended to crash on I/O errors on Python 2, due to forgetting to update some 'except OSError's. Catch EnvironmentError instead. EnvironmentError is a common base class of IOError and OSError on Python 2, and an alias for OSError on Python 3. Use it elsewhere too, as it might help catch obscure I/O errors on Python 2.

Improve warning control API (with backwards compatibility)

2019-06-03T04:50:06Z

A wart of the warning control API (enable/disable_*_warnings()) is that the current warning settings can't be queried. Querying warning settings is useful in functions that want to temporarily enable/disable some warning and then put things back to how they were. kconfiglib.load_allconfig() ran into this, for example. Make the internal warning control variables public (improve the naming at the same time), and encourage just setting them directly. Keep the old API for backwards compatibility. Also remove _warn_redun_assign() and _warn_override(). They're trivial and were called in a single place.

Have load_config() and write_(min_)config() return messages

2019-06-03T04:50:06Z

Hardcoding load_config() and write_(min_)config() to write any message to stdout is awkward, because it means that the message can't be easily reused when stdout is the wrong place to write it to (e.g. in menuconfig/guiconfig). This gets extra bad now that there's also the "No change to ..." message. Modify load_config() and write_(min_)config() to return the message as a string instead, and have them always return a message, instead of just when 'filename' is None and verbose=True. This makes things flexible and straightforward. Use the new behavior in menuconfig.py and guiconfig.py. They now show "No change to ..." when saving a file doesn't modify it. Tools that want to write messages to stdout should now do print(kconf.load_config()) / print(kconf.write_config()). There's no clean way to preserve perfect backwards compatibility here, but keep accepting the 'verbose' argument and print a deprecation warning if a value is ever passed for it. That way, scripts will keep running, though possibly with less output on stdout. This changes the meaning of the load_config() return value as well, though I suspect it was only ever used by the menuconfig/guiconfig interfaces. The new behavior applies for kconfiglib.VERSION >= (12, 0, 0).

String repetition consistency nit

2019-05-19T00:26:13Z

Use a consistent style in examples

2019-03-06T01:15:29Z

Also remove some unused imports.

Use a consistent import style in the examples

2018-09-27T17:54:45Z

Do the PEP 8 ordering thingy with standard library imports first.

Rename examples/menuconfig.py to menuconfig_example.py

2018-04-30T23:28:44Z

To avoid confusing it with the new terminal menuconfig implementation. Clean up the README a bit at the same time, removing some stuff that's less essential now (e.g. the menuconfig_example.py "screenshot").
