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.
|
|
It's not obvious that Symbol.config_string can be useful even when
generating other output formats, as it provides a hook for
_write_to_conf. Mention it in the 'config_string' documentation and in
relevant parts of the README.
|
|
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.

Might be tricky to discover.

The link accidentally went to kconfig-macro-language.txt.
|
|
|
|
Remove some parentheses.
|
|
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.
|
|
For projects that don't use incremental build information, it's a bit
wasteful to generate it just to get an updated .config file to include
in Makefiles. Add a '--config-out <filename>' option that just writes
the updated .config file, for those cases.
Also remove a redundant default=None argument for --sync-deps. None is
the default value.

Just adds commit 4af2ac3 ("Actually fix README RST display on PyPI").
|
|
Use anonymous hyperlinks to avoid having two links named 'Kconfig', like
in commit fe28703 ("Fix README RST display on PyPI").

Just adds commit fe28703 ("Fix README RST display on PyPI").
|
|
Use anonymous hyperlinks to avoid having two links named 'here', which
RST apparently doesn't like.

Gets the README updated from commit 534e3e7 ("Add a 'getting started'
section to the README") up on PyPI.
|
|
|
|
|
|
Might make it clearer how the different parts fit together.
Also mention that deps/auto.conf can be used as Make input, and that it's
preferable to using .config. This is hard to discover on your own.

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")
|
|
Also mention that menuconfig.py has documentation.
|
|
Adds commit 43e7711 ("setup: Use a list instead of a tuple for
'classifiers'"), which fixes a setup.py issue on Python 3.7.
|
|
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")
|
|
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").
|
|
Allow preprocessor functions to be defined in Python by putting a module
called 'kconfigfunctions' into sys.path. Internally, this simply adds
the functions to the predefined functions in Kconfig._functions.
User-defined Python functions make it simple to integrate information
from existing Python tools into Kconfig, e.g. to have Kconfig symbols
depend on hardware information stored in some other format. This might
be used to get device tree information into Kconfig in Zephyr.
Piggyback module docstring documentation for some extensions that were
previously only mentioned in the README.

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.
|
|
|
|
Makes the README much less spammy.
|
|
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.

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().

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.
