Kconfiglib.git/oldconfig.py, branch v12.9.0

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).

Remove some comments re. setup.py entry points

Only appeared in two of the scripts, and main() is such a common convention anyway.

Make .config.old easier to discover

2019-05-19T01:07:47Z

Mention that the old version of an overwritten configuration file is saved to .old in a few different places, to make it easier to discover.

Whitespace consistency nit

Convert some comments to module docstrings in utilities

2019-03-22T16:29:12Z

This makes running pydoc(3) on the utilities helpful. Reuse the module docstring for the --help text for utilities that use argparse. Also fix some copy-paste errors in the all*config.py descriptions and clean up the language a bit. Piggyback removal of an optimization in allmodconfig.py that's pretty irrelevant now.

oldconfig: Style nit

Use a consistent style in small utilities

2019-03-06T01:03:41Z

Also remove some no longer used imports.

Make {load,write}_config(filename=None) implement the standard behavior

2018-12-08T02:28:52Z

Make the previously obligatory 'filename' argument to load_config() and write_config() default to None, and have that implement the behavior you'd usually want: read/write either KCONFIG_CONFIG or ".config" if unset, and read the 'option defconfig_list' configuration file if KCONFIG_CONFIG/".config" doesn't exist. For load_config(), filename=None also allows the configuration file to be missing without raising an error. load_config() returns True if a local configuration file was loaded, which is useful to check in the menuconfig (if no local configuration file exists, we always want to prompt for saving the configuration when exiting). Also add a 'verbose' argument (default True) to load_config() and read_config() that makes them print which files were read/written in filename=None mode. Also generalize olddefconfig.py and oldconfig.py to not require there to already be a local configuration file. This was a bit silly for olddefconfig.py in particular. Remove the examples/defconfig.py script. It's a duplicate of olddefconfig.py.

olddefconfig: Add script

2018-10-01T02:17:13Z

Works like 'make olddefconfig', updating a configuration by filling in default values for all new symbols. This could also be accomplished by entering the 'menuconfig' interface and saving the configuration, but it's more awkward and less obvious. Piggyback two oldconfig changes: - Mention KCONFIG_CONFIG - Check if the .config file exists before parsing the Kconfig files, instead of after
