Adds fixes for two obscure crashes, related to consecutive empty if's
and toggling symbols without a type in the menuconfig:
- Commit 0e6cd82 ("Fix removal of multiple consecutive 'if' nodes")
- Commit db60270 ("menuconfig: Fix crash when toggling symbols without
a type")
|
|
Adds commit 8be38f2 ("Don't show backtraces for expected exceptions in
tools"), which hides backtraces for expected errors from tools (like
Kconfig syntax errors and missing files).
|
|
Commit 14603c0 ("Make errno/strerror/filename available on IOError")
makes IOError/OSError.errno/strerror/filename available to scripts, when
it is raised from e.g. Kconfig.load_config().
Previously, some implementation trickery related to custom exception
messages meant that they weren't available.
|
|
Adds commit 699fd81 ("Support enabling the assignment-to-undef. symbol
warning via the environment"). This makes it possible to enable the
warning for assigning an undefined symbol within a .config file, while
using the bundled tools.
Previously, enabling the warning required modifying the tools to call
Kconfig.enable_undef_warnings().
|
|
- Commit 85ba6b2 ("menuconfig: Mention jump-to in info dialog help")
makes it a bit easier to discover that jump-to can be entered from
the info dialog.
- Commit d920dbe ("Use standard_sc_expr_str() in _name_and_loc()")
makes named choices show up as '<choice NAME>' in warnings, instead
of just as 'NAME'.
Some small parsing optimizations are included as well.
|
|
- Commit 9a4127a ("Allow programmatically expanding preprocessor
functions with args") adds a Variable.expanded_value_w_args()
function for calling preprocessor functions programmatically.
Not being able to pass arguments to Variable.expanded_value was an
oversight.
- Commit 516deb4 ("menuconfig: Show the selected symbol for promptless
choices") makes menuconfig show the selected symbol next to
promptless choices in show-all mode. This is relevant for named
choices defined in multiple locations.
Some minor parsing optimizations are included as well.
|
|
Adds commit 98af94d ("Make Kconfig.choices match its description").
Previously, Kconfig.choices was accidentally identical to
Kconfig.unique_choices. It's now crappy as advertised, and keeps
duplicates.
Removing duplicates (while preserving order) was the original reason for
adding Kconfig.unique_defined_syms and Kconfig.unique_choices. It'd be
rare to need Kconfig.choices.
|
|
Adds two small menuconfig improvements/fixes:
- Commit 9a7b374 ("menuconfig: Fix some minor resizing jumpiness on
gnome-terminal")
- Commit 3d0dc9f ("menuconfig: Switch back to "very visible" cursor
after Ctrl-F")
|
|
Adds commit 63bbecb ("menuconfig: Fix crash when pressing Ctrl-F with no
matches in jump-to dialog").
Ctrl-F is the view-help shortcut in the jump-to dialog.
|
|
Adds two menuconfig improvements and a documentation improvement:
- Commit 96682d7 ("menuconfig: Add jump-to for choices, menus, and
comments") generalizes the jump-to feature so that choices, menus,
and comments can be jumped to in addition to symbols (or into, in the
case of choices and menus).
- Commit fae2e70 ("menuconfig: Do not show range hint for symbols
without ranges") despams the menuconfig interface and could
potentially avoid some confusion.
- Commit bde4cc7 ("Add some hints re. generating custom configuration
output") adds some documentation hints re. using the
Symbol.config_string field when generating custom output. It can be
useful for pruning symbols even when the output format isn't
.config-like.
|
|
Adds commit a247f3f ("menuconfig: Improve/fix promptless choice
handling"), which fixes an obscure menuconfig crash involving symbols in
promptless choices, and improves how choices are displayed in
show-all/show-name mode a bit ('<choice (name, if any)>' instead of
either nothing or '<name>').
|
|
Adds commit f1e4d04 ("menuconfig: Remove "Value for " prefix from input
dialog titles"), which de-spams the menuconfig interface a bit.
Some documentation fixes and improvements are included as well:
- Commit 631c51f ("Point to IS_ENABLED() is README")
- Commit f594975 ("Add hints on incremental building to 'getting
started'")
- Commit d044ee9 ("Clarify --config-out description a bit")
- Commit 358b77a ("Hint that load_config() with replace=False is for
merging")
- Commit 5d15df9 ("Update genconfig usage description")
The naming in some internal evaluation functions was cleaned up too.
|
|
Adds commit 4602028 ("genconfig: Allow writing a full .config without
incremental build info"), which adds a flag to genconfig that might be
handy in projects that include .config files in Makefiles but that don't
use incremental build information.
|
|
Just adds commit 4af2ac3 ("Actually fix README RST display on PyPI").
|
|
Just adds commit fe28703 ("Fix README RST display on PyPI").
|
|
Gets the README updated from commit 534e3e7 ("Add a 'getting started'
section to the README") up on PyPI.
|
|
Adds commit 21e47ce ("Fix parse error message on the line after help
texts"), which fixes incorrect line contents being reported for parse
errors on the line after a help text.
|
|
Adds some documentation nits:
- 08abf44 ("Mention that pydoc works after installing with pip")
- 6aaf01c ("Clean up documentation a bit re. named choice")
- 6fe5198 ("menuconfig: Mark quit_dialog() as internal")
|
|
Adds commit 43e7711 ("setup: Use a list instead of a tuple for
'classifiers'"), which fixes a setup.py issue on Python 3.7.
|
|
Fixes a warning on Python 3.7:
Warning: 'classifiers' should be a list, got type 'tuple'
Maybe it could prevent other issues too:
https://github.com/pypa/pypi-legacy/issues/670
|
|
Adds commit 3b692df ("olddefconfig: Add script"), which bundles a new
script that mimics 'make olddefconfig'. This could also be accomplished
by entering the menuconfig interface and saving, but its more awkward.
Some minor internal documentation clarifications and cleanups are
included as well:
- Commit 53db3ee ("Clarify node_iter() documentation re. iteration order")
- Commit c1dcaa3 ("Refactor parsing to get rid of _saved_line")
- Commit 6aab113 ("Don't set filename and linenr on 'if' menu nodes")
|
|
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
|
|
Adds commit c91e17c ("Give clearer errors for bad
endchoice/endif/endmenu nesting"). Previously, an
endchoice/endif/endmenu without a corresponding choice/if/menu generated
a cryptic "unrecognized construct" error.
|
|
Adds support for user-defined preprocessor functions in Python, which
can be used to get information from existing Python tools into Kconfig,
e.g. to have Kconfig symbols depend on hardware information stored in
some other format.
See commit b6827ca ("Add support for user-defined Python preprocessor
functions").
|
|
Adds commit b9b2ebb ("menuconfig: Add RGB color support to styles."),
which makes it possible to specify colors in MENUCONFIG_STYLE
using #RRGGBB notation.
The rendered colors may be more or less exact depending on terminal
capabilities. In the best case, we can redefine colors. Otherwise, we
fall back on the closest available color.
Contributed by Mitja Horvat (punkfluid).
|
|
Adds commit af6c8dc ("menuconfig: Fix some glitching on small
terminals"), which fixes some minor graphical glitching in the
menuconfig interface when the terminal is too small for things to fit.
Commit 374f488 ("Clean up kernel Makefile patch and add new targets")
adds some new targets to the Linux makefile patch as well, though the
makefile patch isn't bundled on PyPI.
|
|
New features:
- Commit ac8d152 ("menuconfig: Add support for custom color schemes
(aka styles)"), contributed by Mitja Horvat (pinkfluid), adds support
for configuring the style (colors and attributes) of menuconfig
interface elements by setting a new MENUCONFIG_STYLE environment
variable.
The format of MENUCONFIG_STYLE is documented in the menuconfig.py
module docstring. This format is now used internally as well to
define the predefined styles.
- Commit a092257 ("Allow macro expansion within symbol names") adds
support for expanding macros within symbol names. This could be used
e.g. to define template Kconfig files that get instantiated by
setting preprocessor variables before including them.
Other changes:
- Commit 6683213 ("Allow user values on 'option env' symbols") makes it
possible to give 'option env' symbols user values. There's no good
reason to disallow it (it's a leftover from an older way of
implementing them), and it simplifies the code a bit.
Note that 'option env' symbols are only supported for backwards
compatibility at this point. Environment variables can be expanded
directly.
|
|
Adds a small menuconfig tweak that could avoid some user confusion:
Commit 66a2bf5 ("menuconfig: Do not use red for invisible symbols
outside of show-all mode")
|
|
New features:
- Commit 84bd863 ("menuconfig: Add a more 'make menuconfig'-like color
scheme") adds an alternative menuconfig color scheme contributed by
contributed by Mitja Horvat (pinkfluid).
The new color scheme can be enabled by setting the environment
variable MENUCONFIG_THEME to 'aquatic'.
The default color scheme now also uses bold text for the selected
entry, like the 'aquatic' theme.
Fixes:
- Commit d1e2a65 ("menuconfig: Always show implicit submenus with
visible nodes") fixes a display issue involving prompt-only
conditions where visible child nodes could disappear outside of
show-all mode.
Other changes:
- Commit 0ed2ba0 ("Improve the running-without-Makefile-patch
documentation") updates the documentation on how to run Kconfiglib on
the Linux kernel without using the Makefile patch.
- Misc. internal menuconfig refactoring.
|
|
New features:
- Commit 20de53b ("Add a Kconfig.kconfig_filenames attribute") and
commit 932d0f7 ("Add a Kconfig.env_vars attribute that lists env.
variables") make lists of all Kconfig files and referenced
environment variables available.
This could be used e.g. to implement alternative incremental build
schemes. Note that the sync_deps() mechanism already indirectly
catches any relevant changes to files and environment variables
though (anything that changes the configuration output).
- Commit 17d7c1e ("menuconfig: Show all symbols at each menu location
for multi.def. choices") makes it so that if a named choice is
defined in multiple locations, each of which adds options, you can
select any of the options regardless of via menu entry you enter the
choice.
Previously, you could only select the options defined at that menu
entry's location.
Named choices with symbols in more than one location are completely
broken in the C tools, so there's no reference for the behavior
there. This seems less confusing at least.
Suggested by Mitja Horvat (pinkfluid).
Fixes:
- Commit 0b46af4 ("menuconfig: Don't return when selecting a choice
symbol with children") improves menuconfig behavior in an extremely
obscure case.
- Commit 1c2c4ae ("oldconfig: Fix help display command for choices")
makes '?' print the help for choices in oldconfig. The command was
accidentally set to '??' there.
- Commit ddfd5df ("Improve menu structure for promptless choices")
fixes a menuconfig display issue for promptless choices (which
can appear "legitimately" if a named choice is defined in multiple
locations to add extra options).
Cleanup:
- Commit 2320b7a ("oldconfig: Use Kconfig.node_iter() and clean up")
- Some manual tree walking in other places has also been rewritten to
use Kconfig.node_iter().
|
|
Some general cleanup:
- Handle the iteration with the new Kconfig.node_iter() helper.
This makes some function so short that they become pointless. Have
just main() + oldconfig(node) + small helper functions.
- Use _name_and_loc_str(sc) for choices too, so that all locations get
reported for named choices defined in multiple locations
- Rewrite the intro to be less wordy and remove the sample session
(leftover from when oldconfig.py was in examples/, and not that
exciting)
- Print "Updated configuration written to..." instead of
"Configuration saved to..."
- Various other nits

Fixes broken-looking menuconfig include path information for items in
the top-level Kconfig file, via commit 64600b3 ("menuconfig: Hide the
include path for top-level items").
|
|
Adds commit 13884e9 ("Show include paths in menuconfig symbol
information"), which adds a MenuNode.include_path attribute to
Kconfiglib.
MenuNode.include_path holds the Kconfig include path of the menu node,
which shows how its Kconfig file got 'source'd, starting from the
top-level Kconfig file.
MenuNode.include_path is used to show include paths in the menuconfig
symbol information. It will also be used in genrest.py in Zephyr, which
generates an RST Kconfig reference.
|
|
Includes two small bug fixes:
- Commit 9b77511 ("Fix file descriptor leak for the top-level Kconfig
file")
- Commit d158fed ("Fix recursive 'source' error reporting")
|
|
New features:
- Commit 7dae988 ("Add a generic node iterator") adds a
Kconfig.node_iter() helper generator for iterating through all menu
nodes in the menu tree, in definition order. Optionally, symbols
defined in multiple locations are only generated once. This generator
is now used internally by write_config() as well.
Suggested by Mitja Horvat (pinkfluid).
- Commit d2c1430 ("Introduce Kconfig.unique_defined_syms and
Kconfig.unique_choices") adds versions of
Kconfig.defined_syms/choices that only include symbols and choices
defined in multiple locations once, while still preserving definition
order.
This is almost always what you want when iterating through (just)
symbols and choices. It removes set() hackery (where it's easy to
accidentally mess up the order) and the like.
Fixes:
- Commit 4ebc2aa ("Flag extra tokens after 'if'/'depends on'/'visible
if' expressions") tightens up syntax checking so that extra trailing
tokens after 'if', 'depends on', and 'visible if' expressions raise a
syntax error, instead of being silently ignored. Oversight.
|
|
Adds commit 7f3844f ("Make symbol order match between headers and
.config files"), which fixes a bug introduced by commit 71872a8
("Massively speed up U-Boot parsing").
The ordering of symbols in header files now matches the order in .config
files again, which was always the intent. It makes things more readable,
and is nice for version control too.
|
|
Adds commit 8a3999b ("Fix $srctree logic for the top-level Kconfig
file"), which fixes an old braino: The top-level Kconfig file passed to
Kconfig.__init__() wasn't looked up relative to $srctree, breaking
out-of-tree operation for scripts unless ugly manual $srctree hacks were
added.
All Kconfig files are now consistently looked up relative to $srctree.
This is a backwards-incompatible change (though with a simple fix), so
the major version is bumped. A note is printed on errors that might be
due to the changed behavior.
|
|
This just reverts commit 8a3999f ("Fix $srctree logic for the top-level
Kconfig file"), so that it can go in a major release instead.
I realized it has enough breakage potential for existing scripts to
warrant a major version bump.
|
|
- Commit 8a3999b ("Fix $srctree logic for the top-level Kconfig file")
fixes a major braino where the top-level Kconfig file passed to
Kconfig.__init__() wasn't looked up relative to $srctree, breaking
out-of-tree operation for e.g. menuconfig.
All Kconfig files are now consistently looked up relative to
$srctree.
- Misc. internal code cleanup
|
|
Kconfiglib changes:
- Commit 1f864b1 ("Support custom printing of symbols/choices in
expressions") adds support for printing symbols and choices with a
custom format in expressions.
This makes it simpler to implement things like like turning all
symbols/choices into links when generating documentation, and
printing symbol values after symbols.
- Commit 6aea8d0 ("Don't pass encoding= to Popen()") fixes an
accidental Python 3.6+ requirement when using the $(shell)
preprocessor function with Python 3.
menuconfig changes:
- Commit 8efc358 ("menuconfig: Omit tristate value hint for
int/string/hex defaults") removes the boolean value hints to the
right of defaults in the symbol information for string/int/hex
symbols. Stuff like '- 74 (value: "n")' isn't helpful, and looks
confusing.
- Commit 3511f24 ("menuconfig: Make symbol information less spammy")
makes the symbol information more compact in general, e.g. by
skipping value hints where they aren't helpful ('FOO(=y)' instead of
'FOO(=y) (=y)'), and by shortening stuff like '(value: "y")' to just
'(=y)'.
|
|
- b650ccd ("Use universal newlines mode in $(shell) implementation")
improves the behavior of $(shell) on Windows. A trailing \r\n-style
newline sequence is now stripped in full, instead of leaving \r in
there.
- 6899f91 ("Restore compatibility with old kernels") restores some
compatibility with old kernels originally dropped by c19fc11 ("Drop
some compatibility and tighten up lexing").
It turns out that people are still running Kconfiglib on kernels from
at least 2013 (see https://github.com/ulfalizer/Kconfiglib/pull/48).
|
|
Just adds commit 5452ad3 ("Fix detection of hex literals"). Braino.
Include some int and hex literals in the Kstrict testcase too.
|
|
Adds support for automatically warning for references to undefined
Kconfig symbols. See commit ca89d02 ("Add KCONFIG_STRICT flag for
flagging refs. to undefined syms").
(There was an outdated docstring in that comment. KCONFIG_STRICT needs
to be set to "y".)
|
|
Adds e08b695 ("Add def_int, def_hex, and def_string keywords"), getting
rid of some Kconfig inconsistency.
|
|
https://github.com/clearlinux-pkgs/python-kconfiglib adds a patch for
this.
It avoids issues on systems that use the C locale, which implies ASCII
encoding and raises UnicodeDecodeError when reading README.rst.
Piggyback adding 'menuconfig' as another keyword.
|
|
This release revamps the globbing design to make 'source' globbing,
requiring at least at least one matching file. A new o(r)source
statement can be used when it's okay for a pattern to not match any
files.
Relevant commit, with motivations: 7a428aa ("Switch to more sensible
globbing statements (w/ backwards compatibility)").
Backwards compatibility is maintained by having g(r)source be an alias
for o(r)source.
A small API change was introduced too: Kconfig.srctree is now set to the
empty string instead of None when $srctree is unset. This gives nice
behavior for e.g. os.path.join().
|
|
This release adds commit ac692af ("Fix absolute $srctree prefixes
showing up on gsource'd files"), which fixes a bug that could cause
$srctree to be included in some paths for e.g. generated documentation.
|
|
This release improves performance for projects that make heavy use of
multiple definition locations for symbols, via commit 747e455
("Massively speed up U-Boot parsing").
Two new warnings are included as well:
- 652d991 ("Warn if int/hex/string symbols are evaluated logically")
- 21b5351 ("Warn if int/hex 'default' is outside active 'range'")
|
|
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.
|
|
New features:
- db92bb7 ("Add dependency loop detection") adds long-overdue
dependency loop detection.
Previously, dependency loops would trigger hard-to-debug Python
RecursionError exceptions during evaluation. They now generate a
KconfigError instead, with a helpful message that shows the items in
the loop.
Backwards-incompatible changes (major version bumped to 7):
- eb6c21a ("Turn MenuNode/Symbol/Choice.referenced() into a
@property") fixes some inconsistency in the recently-added
referenced-symbols APIs. Oversight.
Other changes:
- f6eb4f4 ("Add Symbol/Choice.referenced() convenience methods")
makes it easier to get all the symbols/choices referenced by a
symbol or choice. Previously, you'd have to loop through all the
menu nodes (definition locations) yourself, which might not be
obvious.
- ca89ca0 ("Rename KconfigSyntaxError to KconfigError") changes to
a better exception name, as KconfigSyntaxError was raised for some
things that aren't syntax errors.
The old name is kept as an alias for now for backwards
compatibility.
