2015-06-05Revert "_parse_block() style nit."Ulf Magnusson
Ops... this breaks menu ordering.
2015-06-05_parse_block() style nit.Ulf Magnusson
2015-06-05_internal_error() nit.Ulf Magnusson
2015-06-05Format some stuff consistently.Ulf Magnusson
2015-06-05Use the 'get' method of 'keyword' directly.Ulf Magnusson
Small tokenizer optimization, similar to the regex optimizations.
2015-06-05Improve tokenization performance by removing a single character.Ulf Magnusson
strip() instead of lstrip() makes the loop terminate earlier, saving lots of calls. Shaves a few % of parsing the x86 Kconfigs.
2015-06-05Restructure and simplify parts of the tokenizer.Ulf Magnusson
Pre-bump 'i' and let it be the index of the "next" character instead.
2015-06-05Fix hang when tokenizing some invalid expressions.Ulf Magnusson
c.eval("&") would cause a hang before for example.
2015-06-04Clean up parse error handling.Ulf Magnusson
strip() the faulty line (seeing that whitespace probably isn't helpful), remove an assert that probably isn't useful in practice, and simplify the code.
2015-06-04Clean up tokenization error handling.Ulf Magnusson
- The caret was always set to the end of the string in the current version, which is pointless. - Part of the error string was output manually, and part of it was part of the exception message. Ugly oversight.
2015-06-04Documentation nit.Ulf Magnusson
2015-06-04Refactor and optimize _indentation().Ulf Magnusson
I must have missed that expandtabs() already takes the context of tabs into account the first time around. Also remove error check that probably won't be useful.
2015-06-04Refactor and optimize _strip_quotes().Ulf Magnusson
Use the fact that startswith() can check multiple prefixes.
2015-06-04Replace _strip_trailing_slash() with rstrip().Ulf Magnusson
Will also strip many '/'s, which makes sense here.
2015-06-04Refactor _get_lines().Ulf Magnusson
Also improves performance. A yield-based implementation would be interesting to experiment with, to see if I/O + computation interleaving helps here.
2015-06-04Note that _FileFeed joins lines ending in \.Ulf Magnusson
2015-06-04Let _FileFeed fetch the lines from the file.Ulf Magnusson
This is how it's always used in practice.
2015-06-04Order _parse_block() cases by frequency.Ulf Magnusson
Probably not a noticeable win here, but might as well. The new ordering isn't any worse than the old one in other respects. Also remove a pointless assert. The condition would trigger an obvious error immediately when false anyway.
2015-06-04Order _parse_properties() cases by frequency.Ulf Magnusson
Shaves a few % off parsing the x86 Kconfigs.
2015-06-04Check for AND before OR in _eval_expr_2().Ulf Magnusson
Much more common, so make it the fast case.
2015-06-04Small regex-related optimization.Ulf Magnusson
Prefetch the SRE_Pattern.match() methods. Shaves a few % off Config._tokenize(). Do the same elsewhere for consistency, though I'm not sure if it's a meaningful win.
2015-06-04Warning formatting nit.Ulf Magnusson
2015-06-04Consistently use new-style classes.Ulf Magnusson
Ugly oversight. Gives a nice ~13% parsing performance increase with both CPython and PyPy on my system.
2015-06-02Remove Psyco support.Ulf Magnusson
Psyco is dead, and there's PyPy now.
2015-06-02Obfuscate email inside kconfiglib.py.Ulf Magnusson
2015-06-01Use ulfalizer@gmail.com for feedback.Ulf Magnusson
Harder to miss stuff that way.
2015-05-31Do a small documentation cleanup pass.Ulf Magnusson
- Clean up introduction a bit. - Explain that "# CONFIG_FOO is not set" is treated specially. - Remove some silly "otherwise False" comments where it's obvious. - Reformulate a few things slightly.
2015-05-29Fix typo in warning.Ulf Magnusson
2015-05-29Only warn for 'option modules' on non-MODULES symbols.Ulf Magnusson
2015-05-25Allow digits in $-references to symbols.Ulf Magnusson
Omission which didn't matter for the Linux kernel. sym_expand_string_value() in scripts/kconfig/symbol.c is the relevant part of the C implementation. Seems the Buildroot guys ran into it.
2015-05-25Fix typo in docs.Ulf Magnusson
2015-05-24Add warning related to get_defconfig_filename().Ulf Magnusson
Might not match 'make defconfig' if the --defconfig override is used. Should probably be improved.
2015-03-13Hint that modules are still supported despite warnings.Ulf Magnusson
2015-03-12Add Symbol.is_allnoconfig_y()Philip Craig
2015-03-12Statements in choices inherit menu/if depsPhilip Craig
This fixes the deps for the comment in drivers/usb/dwc2/Kconfig.
2015-02-16Warn about and ignore the "allnoconfig_y" Kconfig optionJakub Sitnicki
A new option has appeared in Linux 3.15-rc1. Ignore it for now.
2013-08-07Add Symbol and Choice interfaces for getting prompt strings.Ulf Magnusson
2012-12-19Use regexes instead of frozensets to lex ids/keywords.Ulf Magnusson
Faster and a bit more readable.
2012-12-18Flesh out Symbol docstring.Ulf Magnusson
2012-12-18Flesh out Config docstring.Ulf Magnusson
2012-12-18Remove redundant invalidation from load_config().Ulf Magnusson
unset_user_values() will indirectly invalidate everything, so we don't need to do it ourselves.
2012-12-18Properly unescape .config string assignments.Ulf Magnusson
2012-12-18Simplify load_config() a bit.Ulf Magnusson
2012-12-18Escape \ and " when writing .config entries for strings.Ulf Magnusson
2012-12-17Tighten up string literal parsing a bit more.Ulf Magnusson
2012-12-17Fix comment re. fast path.Ulf Magnusson
2012-12-17Small simplification.Ulf Magnusson
2012-12-17Add a fast path for string literal lexing.Ulf Magnusson
Speeds up _tokenize() by ~20%.
2012-12-16Use 'while 1' instead of 'while True'.Ulf Magnusson
Bit faster (http://wiki.python.org/moin/PythonSpeed).
2012-12-16Use | and |= instead of set.union() and set.update().Ulf Magnusson
