Kconfiglib.git, branch v8.0.0Fork of https://github.com/zephyrproject-rtos/Kconfiglib.githttps://git.mcdonnell.dev/Kconfiglib.git/atom?h=v8.0.02018-07-10T07:13:54ZMake 8.0.0 release2018-07-10T07:13:54ZUlf Magnussonulfalizer@gmail.com2018-07-10T07:13:07Zurn:sha1:8ff1be9dcf7d7d30fce553b0ed21b40bbc26cae7
New features:
- 2433deb ("Add Kconfig preprocessor") implements a new Kconfig
preprocessor, documented in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/kconfig-macro-language.txt.
It is required to parse the linux-next Kconfigs now, and will appear
in Linux 4.18.
'option env=...' symbols and the $FOO syntax for expanding
environment variables will be supported for backwards compatibility
for a while. Consider switching to $(FOO) though, which is the new
syntax (and removing 'option env=...' symbols).
Changed behavior:
- c19fc11 ("Drop some compatibility and tighten up lexing") makes
Kconfiglib flag invalid characters in Kconfig files as a syntax
error in all context. They were previously ignored in some places
for compatibility with old sloppy versions of the C tools.
The C tools fixed it with commit c2264564 ("kconfig: warn of
unhandled characters in Kconfig commands") in July 2015. Older
kernels might require fixing up the Kconfig files a bit now.
New warnings:
- 4200e25 ("Generalize select-with-unsatisfied-deps warning") makes
the select-with-unsatisfied-dependencies warning trigger when a
symbol with m-valued direct dependencies is y-selected.

Add Kconfig preprocessor2018-07-10T05:56:37ZUlf Magnussonulfalizer@gmail.com2018-07-03T16:30:06Zurn:sha1:2433deba7889931c4bae679f116887fe49a2ce04
Implement the Kconfig preprocessor described in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/kconfig-macro-language.txt
(which is now in linux-next and will appear in Linux 4.18).
A new Kconfig.variables property holds all the preprocessor variables so
that they can be inspected programmatically. Preprocessor variables are
represented by a new Variable class.
With the preprocessor, environment variables are referenced with $(FOO)
instead of $FOO. For backwards compatibility, $FOO is accepted as well
for now (and leaves "$FOO" as-is if FOO doesn't exist). The $FOO syntax
might be dropped at some point in the future (together with a major
version increase). It should be supported for a few months at least.
Some internals were cleaned up too, mostly related to parsing. Some
outdated documentation was fixed as well.
Generalize select-with-unsatisfied-deps warning2018-07-10T05:55:56ZUlf Magnussonulfalizer@gmail.com2018-07-10T05:46:47Zurn:sha1:4200e25c24a4441b36d6ac2d3d30987d88515eb2
y-selecting a symbol with direct dependencies m should be flagged as
well. Mirrors a change to the C tools.
Refactor tokenization a bit2018-07-02T02:36:17ZUlf Magnussonulfalizer@gmail.com2018-07-02T02:23:50Zurn:sha1:86a3c2da10491f7cec96a9c2720a5cd92b8aad67
Have _tokenize() take the string to tokenize and return a list of
tokens, and handle all the token list management outside.
Simplifies the internal logic a bit. Likely faster too.
Simplify some dict.get() calls by passing defaults2018-07-02T01:25:58ZUlf Magnussonulfalizer@gmail.com2018-07-02T01:25:58Zurn:sha1:db90cb85094a2cab19a524ad30b603e26cbb76feSimplify some _warn() calls2018-07-02T00:05:13ZUlf Magnussonulfalizer@gmail.com2018-07-02T00:05:13Zurn:sha1:b487258624b26eef061938827a9e1e700ce04858Tighten up named choice parsing2018-07-01T23:46:52ZUlf Magnussonulfalizer@gmail.com2018-07-01T22:48:45Zurn:sha1:b5c719b72320b655b448cfd91feb5eee5eadebd7
Things like 'choice NAMED_CHOICE oops extra tokens' and 'choice &&' are
now detected as syntax errors.
Bit faster too, though it doesn't matter here.
Number tokens from 1 to simplify some checks2018-07-01T22:31:20ZUlf Magnussonulfalizer@gmail.com2018-07-01T21:40:15Zurn:sha1:0c28974bedd21e5c992ae9667e75f800dc04fe32
This makes all tokens except empty strings truthy, getting rid of some
'is (not) None' checks.
Drop some compatibility and tighten up lexing2018-07-01T21:14:14ZUlf Magnussonulfalizer@gmail.com2018-07-01T20:38:13Zurn:sha1:c19fc11355b13d75d97286402c7a933fb23d3b70
Old versions of the C tools used to ignore unhandled characters in some
contexts due to sloppy lexing, which Kconfiglib emulated for
compatibility (things like "---help---" used to depend on it).
This was improved in the C tools by commit c2264564 ("kconfig: warn of
unhandled characters in Kconfig commands"), committed in July 2015.
Remove the compatibility hack and tighten up the lexing in Kconfiglib as
well. It will make implementing the new preprocessor stuff smoother.
The major version will be bumped.
