Adds a utility for setting configuration values from the command line,
in commit 22d3cc3 ("setconfig: Add script").
|
|
This is a simple script for updating configuration values from the
command line, with (optional) checking that the assigned value matches
the actual symbol value afterwards (which it might not if there are
unsatisfied dependencies).
Sample usage:
$ setconfig FOO_SUPPORT=y BAR_BITS=8
This is useful for patching the configuration in automated build
systems, in a way that's safer than directly patching configuration
files.
|
|
Adds commit c9c7f59 ("Package LICENSE.txt in source distributions and
wheels"), by request. Maybe some distros require this.
|
|
- Commit 3a3559f ("menuconfig: Prompt for save if a different .config
would be saved") improves the behavior of menuconfig.py when Kconfig
files are modified between sessions, fixing issue #63.
Modifying Kconfig files in a way that would affect the written
.config now always makes the menuconfig prompts for saving the
configuration on exit.
A new Kconfig.missing_syms attribute is added as well, which was
needed to implement the improved behavior with public APIs.
- Commit b64c961 ("Warn for '# CONFIG_FOO is not set' when FOO is
referenced but undefined") fixes a small oversight re. the
assignment-to-undefined-symbol warning.
|
|
Adds commit dcb6f12 ("menuconfig: Add show-help mode"), which adds a new
mode to the menuconfig that replaces the key listing at the bottom with
the help text of the selected item.
|
|
Adds an error reporting improvement and an example code fix:
- Commit 0266924 ("Improve error for missing endchoice/endif/endmenu")
- Commit a88302b ("Fix user-defined preprocessor function example
code")
Some minor performance improvements are included as well.
|
|
Adds commit be3c682 ("Clarify that load_config()'s filename argument
defaults to None"), which fixes a small documentation bug.
|
|
Adds commit e8f9751 ("genconfig: Do not generate *.old files for
--config-out"), which gets rid some probably redundant .config.old
files.
|
|
- Commit 3cc2f9f ("listnewconfig: Add script") adds
'make listnewconfig' functionality. The new script is bundled in the
pip install.
- Commit 78073d6 ("Preserve symlinks when writing .config.old files")
avoids stomping on symlinks when writing configuration files.
|
|
Mirrors 'make listnewconfig' in the C tools.
|
|
Adds two improvements related to configuration files:
- Commit 166be7d ("Save existing configuration to .<filename>.old in
write_config()")
- Commit 7b4f72f ("Make {load,write}_config(filename=None) implement
the standard behavior")
|
|
Adds a small incremental building improvement: commit a4751b5 ("Flag
removed symbols as changed in sync_deps()")
|
|
Adds commit 567cccf ("Tighten up help text parsing"), which improves
parsing performance slightly.
|
|
Adds commit b3f0061 ("menuconfig: Only list duplicated choice symbols
once"), which improves the behavior of the menuconfig interface for an
obscure situation involving named choices included multiple times.
|
|
Adds some small performance optimizations:
- Commit 120f551 ("Speed up more token membership tests")
- Commit bb7044c ("Reorder some tuples to put y first")
|
|
Adds commit 67ce4eb ("Use constants when _tokens_i is known"), which
adds more optimizations made possible by switching to more manual token
handling.
|
|
Adds a small missed optimization opportunity, in commit 74ce9d3
("Optimize fetching of initial token on line").
|
|
Tightens up syntax checking and improves a warning:
- Commit 13a7bae ("Flag extra trailing tokens in all contexts") adds
checking for extra trailing tokens in a few overlooked cases.
- Commit f356ba8 ("Clarify that select/imply is a no-op for choice
symbols") clarifies the warning when selecting/implying a choice
symbol.
Parsing performance was improved slightly as well.
|
|
- Commit ee25489 ("menuconfig: Print '----' instead of '---> (empty)'")
makes the menuconfig display empty menus (e.g. from disabled
'menuconfig' symbols) in a less spammy way, matching the C tools.
- Commit 6313925 ("Remove message re. Kconfiglib 10 backwards compat.
break") removes an old message printed when the top-level Kconfig
file can't be opened and $srctree is set. Hopefully it's been noticed
by now.
- Commit a1a4430 ("Use 'foo.__class__ is Bar' instead of
'isinstance(foo, Bar)'") improves parsing and evaluation performance a
bit.
|
|
Adds commit df61771 ("menuconfig: Never snap scroll back to
max_scroll"), which fixes a small menuconfig UI nit.
Add 'configuration-management' as a tag to setup.py as well.
|
|
Adds commit b65baa4 ("Add support for KCONFIG_ALLCONFIG"), which allows
particular symbol values to be forced during all{def,no,mod,yes}config.
|
|
Adds two small library/menuconfig improvements:
- Commit 7992519 ("Always strip trailing whitespace in 'MenuNode.help'
and __str__()") tightens up the format of strings a bit, and
documents it.
- Commit b810bda ("menuconfig: Support HOME and END in the jump-to
dialog") adds support for some keys that were missing from the
jump-to dialog.
|
|
Adds a small menuconfig improvement: Commit 35af004 ("menuconfig: Move
cursor to choice selection when entering choices").
|
|
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.

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.
