2017-09-24Pass 'license' param to setuptools.setup()v1.0.2Ulf Magnusson
Shows up when you do 'pip show kconfiglib', which previously showed UNKNOWN for the license. I was hoping it'd be inferred from the trove classifiers. Make this a 1.0.2 release.
2017-09-24Use --user with pip in the example commandUlf Magnusson
Will make it work for most people out of the box, plus it's good default practice anyway.
2017-09-24Make 1.0.1 releasev1.0.1Ulf Magnusson
Gets the get_defconfig_filename() fixes out.
2017-09-24Use os.access() in get_defconfig_filename()Ulf Magnusson
...instead of os.path.exists(). This more closely mimics the test in the C implementation, which boils down to fopen(file, "r") == NULL. Could open(filename) and catch exceptions too, but it might be overkilling things.
2017-09-24Fix defconfig srctree absolute/relative mixup bugUlf Magnusson
This code in zconf.l says !=, not ==. Thought the behavior seemed weird. if (!f && name != NULL && name[0] != '/') { env = getenv(SRCTREE); if (env) { sprintf(fullname, "%s/%s", env, name); f = fopen(fullname, "r"); } } return f; Thankfully only broken for a short while. Also gives much simpler code.
2017-09-24Handle path cleanups in a cleaner wayUlf Magnusson
_clean_up_path() was only ever passed filenames, so stripping trailing slashes was redundant. Better to strike at the root of the problem too, which is the os.path.join() with 'base_dir' defaulting to ".". The old hack gave incorrect results in obscure cases: Turning .//oops into /oops is wrong. The new version should be Windows-friendly as well.
2017-09-24Remove defaulted open() "r" argumentUlf Magnusson
2017-09-24Fix get_defconfig_filename() $srctree search orderUlf Magnusson
Previously, $srctree/path/to/defconfig would be looked up before /path/to/defconfig, and the code wouldn't check if /path/to/defconfig was an absolute path ($srctree is ignored otherwise). Sloppy old oversights. The behavior now fully matches the C implementation. Also fix some related things: - An 'if m' suffices to select a defconfig. We previously required 'y'. - Make the code less hacky and possibly more Windows-friendly by using os.path.relpath() to de-absolutize paths, and stop using os.path.normpath() as it could change the meaning of paths that contain symbolic links. - Explain what happens if 'option defconfig_list' is set on multiple symbols and print a warning in that case. - Fix get_srctree(). It would previously return "." instead of None if $srctree was unset at parse time. Somehow forgot to to test this. The code is now much more straightforward.
2017-09-24Add _parse_cond() helper for some 'if <y>' casesUlf Magnusson
There's already parse_val_and_cond(), which handles '<x> if <y>' where both <x> and <y> need to be parsed. Add a corresponding _parse_cond() helper which can be used in cases where only <y> should be parsed (for 'select', 'imply', and 'range'). Also move both _parse_val_and_cond() and _parse_cond() outside _parse_properties(). More explicit, and shows a small performance improvement during parsing.
2017-09-23Make the PyPI link point to the Kconfiglib pageUlf Magnusson
Bit more specific than https://pypi.python.org.
2017-09-23Fix README typoUlf Magnusson
2017-09-23Linkify another kconfiglib.py in the READMEUlf Magnusson
2017-09-23Add installation instructions for PyPIv1.0.0Ulf Magnusson
Along with the v1.0.0 tag. First version has been pushed to PyPI.
2017-09-23Modernize and update installation filesUlf Magnusson
Preparation for adding to PyPI. Switch to setuptools and add a bunch more metadata. Use semantic versioning (http://semver.org).
2017-09-23Use a separate LICENSE.txt for the ISC licenseUlf Magnusson
Packaging preparation. Unspams the README a bit (but spams the tree...). Should make GitHub display the license automatically.
2017-09-23README formatting nitUlf Magnusson
2017-09-23Switch README format to reStructuredTextUlf Magnusson
In preparation for creating a PyPI package. This is the documentation format PyPI expects. Some automatic conversion workarounds can be found on Google, but keep it simple and eliminate a step. Add a fancy table of contents using ::contents too.
2017-09-22Fix README typoUlf Magnusson
2017-09-22Explain why _make_and() can return NoneUlf Magnusson
Makes ANDs between nonexistent expressions yield a nonexistent expression.
2017-09-22Explain the expression structure clearerUlf Magnusson
2017-09-22Simplify _expr_to_str()Ulf Magnusson
- Get rid of _sym_str_string(), which was only used here. - Remove 'if expr is None' case that could never trigger - Add a test for printing string symbols, as they are a bit tricky: Default values should not be evaluated to tristate values.
2017-09-21Simplify expression representationUlf Magnusson
Store simple (<operator>, <operand 1>, <operand 2>) tuples instead of (<operator>, [list of operands]) tuples. The thought process behind the original representation was to avoid creating lots of nodes for long X && Y && Z && ... chains that sometimes appear, and possibly speed up evaluation. In retrospect, it's pretty bad, for the following reasons: 1) _make_and() and _make_or() created lots of new merged lists instead of simply reusing the tuples already allocated for the subexpressions. This is slow and memory hungry. 2) Any gain in evaluating long expressions would barely offset slower evaluation of short expressions. 3) The code became more complex. Most importantly, this change makes expressions more straightforward to work with for people peeking into internals.

2017-09-21Fix minor README nitsUlf Magnusson
2017-09-21Touch up the README a bitUlf Magnusson
- Reorder some things by relevance. - Kinda-sorta officially sanction digging into internals (for expressions anyway). - Be a bit less rambling. - Fix dead link to gen-manual-lists.py. It was removed after the listing was removed from the Buildroot manual.
2017-09-21Massively reduce test suite memory usageUlf Magnusson
Previously we would load all arches once in the beginning and reuse them throughout the test suite. With 36 arches with all symbols evaluated and cached, this used many gigabytes of memory (unless the test suite was run with pypy). Restructure things so that we only keep one arch loaded at a time. This adds some reparsing, but it's not a big deal. Do an ugly piggy-backing of some code cleanup in the test suite (mostly using un-numbered {} with format()).
2017-09-21Use non-numbered {} with format()Ulf Magnusson
Supported since Python 2.7, which is seven years old, plus it was already used in a few spots. Do some minor cleanup in the printing routines at the same time. Also remove dubious string append performance note, where it's more about wanting to pass something mutable anyway.
2017-09-20_parse_properties() nitUlf Magnusson
2017-09-20Simplify 'end_line' handlingUlf Magnusson
No need to set 'end_line_tokens' to None if we use 'end_line' as a flag. Also clarify the comments to make it clear that end_line* is only used for the first line after a block of properties. Also fix comment typo: s/nested functions/nested menus/
2017-09-20Merge T_DEF_BOOL and T_DEF_TRISTATE casesUlf Magnusson
Extend TOKEN_TO_TYPE to map T_DEF_BOOL and T_DEF_TRISTATE to BOOL and TRISTATE as a convenience.
2017-09-20Use tri_greater() where applicableUlf Magnusson
2017-09-20Add support for less/greater than comparisonsUlf Magnusson
Was added upstream in 31847b67 (kconfig: allow use of relations other than (in)equality). Completely unused (and undocumented) in the kernel except for in DEBUG_UART_8250_WORD in arch/arm/Kconfig.debug: depends on DEBUG_UART_8250_SHIFT >= 2 (That line was added before lt/gt support by the way, and assumed a feature that wasn't there.) This change (and the upstream one) also slightly changes how (in)equality comparisons work, making e.g. MY_HEX = 0x00037 evaluate to 'y' if MY_HEX is 0x37. Prior to this change, the strings needed to match exactly.
2017-09-19Add note on tokenization unhandled character hackUlf Magnusson
Isn't needed to be compatible with the latest upstream, but is kept around for compatibility.
2017-09-19File writing nitUlf Magnusson
2017-09-19Simplify dependency propagation for promptsUlf Magnusson
Old version was a bit roundabout.
2017-09-19Include 'if' deps. in _determine_actual_symbols()Ulf Magnusson
Previously, only WEIRD_1 and not WEIRD_2 would be considered not a choice symbol in the following fragment. This lead to a weird warning in U-Boot. choice config FOO config WEIRD_1 depends on FOO if FOO config WEIRD_2 endif endchoice Also add some testcases for weird choice symbols.
2017-09-19Clean up _parse_block() casesUlf Magnusson
Do the block.append() after parsing the complete item. More obvious.
2017-09-19Simplify block parsing logicUlf Magnusson
Require callers to always pass the list to append items to and remove the return values from _parse_file() and _parse_block(). Initialize menu.block and choice.block to [] rather than None.
2017-09-19testsuite: Use platform.uname() instead of os.uname()Ulf Magnusson

2017-09-18Add 'imply' supportUlf Magnusson
This is like a 'select' that only changes the default value of a symbol, not limiting what values the user can set it to (with one exception: A symbol implied to 'y' can't be set to 'm'). Symbol.get_implied_symbols() was added, corresponding to Symbol.get_selected_symbols(), and Symbol.__str__() was extended to print implied symbols and weak reverse dependencies. Weak reverse dependencies are the 'imply' version of 'select's reverse dependencies.
2017-09-18Force M visibility to N in choices with mode YUlf Magnusson
This mirrors the following kconfig commit. Triggered a few test suite failures for ARM and SH. commit fa64e5f6a35efd5e77d639125d973077ca506074 Author: Dirk Gouders <dirk@gouders.net> Date: Fri Apr 29 10:24:52 2016 +0200 kconfig/symbol.c: handle choice_values that depend on 'm' symbols If choices consist of choice_values of type tristate that depend on symbols set to 'm', those choice_values are not set to 'n' if the choice is changed from 'm' to 'y' (in which case only one active choice_value is allowed). Those values are also written to the config file causing modules to be built when they should not. The following config can be used to reproduce and examine the problem; with the frontend of your choice set "Choice 0" and "Choice 1" to 'm', then set "Tristate Choice" to 'y' and save the configuration: config modules boolean modules default y option modules config dependency tristate "Dependency" default m choice prompt "Tristate Choice" default choice0 config choice0 tristate "Choice 0" config choice1 tristate "Choice 1" depends on dependency endchoice This patch sets tristate choice_values' visibility that depend on symbols set to 'm' to 'n' if the corresponding choice is set to 'y'. This makes them disappear from the choice list and will also cause the choice_values' value set to 'n' in sym_calc_value() and as a result they are written as "not set" to the resulting .config file.
