Fork of https://github.com/zephyrproject-rtos/Kconfiglib.git https://git.mcdonnell.dev/Kconfiglib.git/atom?h=v10.7.0 2018-09-08T17:33:47Z 2018-09-08T17:33:47Z Ulf Magnusson ulfalizer@gmail.com 2018-09-08T15:25:51Z urn:sha1:374f48873424f9167f508a53a80f3ea1c2d41c46 Add two new targets: - 'make kmenuconfig' runs the menuconfig interface - 'make dumpvarsconfig' lists all referenced environment variables together with their values (assuming they used the preprocessor syntax) Remove the 'kconfiglibtestconfig' target, which is no longer used. Also clean up the target definitions. The joys of ancient code. 2018-09-05T10:19:39Z Ulf Magnusson ulfalizer@gmail.com 2018-09-05T10:18:26Z urn:sha1:2be02fac785272e3bcea2cef619954535dc9abe0 Some grammar, some copy-paste errors ('string' should be 'name'). 2018-09-04T19:35:16Z Ulf Magnusson ulfalizer@gmail.com 2018-09-04T19:35:16Z urn:sha1:0591946c28107001f4c5ca725405b8c2270be0dd This is handled earlier in _tokenize() now. 2018-09-04T18:49:21Z Ulf Magnusson ulfalizer@gmail.com 2018-09-04T16:05:28Z urn:sha1:a092257a49ed7850913cf53e474f4c8dd175c94b The C implementation supports this (though it's undocumented, and unused to far). This can be used e.g. to dynamically instatiate symbols from template files: Kconfig.template: config $(subsys)_LOG bool "Enable logging for $(subsys)" depends on $(subsys)_HAS_LOG ... other stuff dependent on $(subsys) Elsewhere: subsys = FOO source "Kconfig.template" subsys = BAR source "Kconfig.template" Pretty sure this can easily be abused, but it should be supported at least. 2018-09-03T10:32:20Z Ulf Magnusson ulfalizer@gmail.com 2018-09-03T08:51:04Z urn:sha1:ef5358e8b8174716470b00691fba9946b7d307ce Saves a few % of total parsing time, and probably some evaluation time too. Microbenchmarking on Python 3 shows that 'is' is about 30% faster than '==' for comparing integers on my machine. This is safe even without assuming Python's small-integer optimization (which caches objects for small integers, guaranteeing that small integer literals always refer to the same object): We always refer to symbolic constants using their symbolic names (_T_*, etc.), so they're guaranteed to always refer to the same integer objects anyway. This optimization is safe for client code too, unless you get some unlikely situation where (1) there is no small-integer optimization, (2) expressions get pickled and unpickled or the like, which would be unsafe across Kconfiglib versions anyway, and (3) the client code tests symbolic constants with 'is' instead of '==' (which isn't advertised as safe, and a bad idea in general when pickling is involved). That's probably too obscure to worry about. 2018-08-30T07:13:22Z Ulf Magnusson ulfalizer@gmail.com 2018-08-30T06:37:59Z urn:sha1:66832138bfb0e82190b55fb410104d969cbc829b Gets rid of a check, doesn't hurt. The check was added before 'option env' was changed to just add a 'default' under the hood. Note: New Kconfig code doesn't need 'option env'. Environment variables are now expanded directly, including in the C tools. 'option env' is only maintained for backwards compatibility. 2018-08-29T02:40:18Z Ulf Magnusson ulfalizer@gmail.com 2018-08-29T02:40:18Z urn:sha1:0ed2ba06ce4b8f22420ecf15dc36476382b8fa02 - Include an updated list of environment variables, with sample values - Give a method for listing all referenced environment variables, via Kconfig.env_vars - Remove the note that says that Kconfiglib will warn if an unset environment variable is referenced. It's not true anymore with the preprocessor, which silently expands unset variables to the empty string. Not setting essential environment variables causes obvious errors at least. 2018-08-29T00:18:32Z Ulf Magnusson ulfalizer@gmail.com 2018-08-29T00:18:32Z urn:sha1:98416f6b65152d6bbc107c625c65b7239cff20f7 Factor out the call to the iterator. 2018-08-26T01:04:30Z Ulf Magnusson ulfalizer@gmail.com 2018-08-26T00:34:23Z urn:sha1:ddfd5df84b4b7871ea16d76e233c11c8b45738d9 Promptless choices can appear "legitimately" if you define a named choice in multiple locations to add on some symbols (which is broken in the C tools though). Prior to this fix, the promptless choice would get flattened, with the choice symbols appearing in the same menu as the (invisible) choice. This looks confusing. Skip flattening promptless choices to fix it. 2018-08-25T18:32:34Z Ulf Magnusson ulfalizer@gmail.com 2018-08-25T18:07:05Z urn:sha1:932d0f7b8a69bdcac5d945de600ce6be807aeff7 Kconfig.env_vars is a set() with the names of all environment variables referenced in the configuration. Can be used e.g. for custom incremental build implementations, though sync_deps() already indirectly catches any relevant changes to environment variables.
