Adds commit 3aea9f7 ("Add '# end of <menu>' after menus in .config"),
which mirrors a change in the C tools. The compatibility tests now pass
again for the latest kernel.
|
|
|
|
Mirrors commit aff11cd983ec ("kconfig: Terminate menu blocks with a
comment in the generated config") in the kernel.
This makes the compatibility tests pass again, and is handy.
|
|
Flatten, and unscrunch the bool/tristate case.
|
|
Consistent with the other ones.
|
|
Not just for syntax errors when raised from Kconfig.__init__().
|
|
|

Brings the format returned by Symbol/Choice/MenuNode.__str__()/custom_str()
closer to how things would usually be written by hand, and removes
spammy propagated dependencies from property conditions.
Propagated dependencies are still included in the 'depends on ...' line,
so no information is lost.
Properties without parent deps. propagated to their conditions are now
also available as MenuNode.orig_{prompt,defaults,selects,implies,ranges}.
- Commit bb33eed ("Strip direct deps. from property conditions in
Symbol/Choice/MenuNode.__str__()")
- Commit e1da7aa ("Display n/m/y without quotes")
- Commit 9f57bf9 ("Use the '<type> "prompt"' shorthand in __str__()")
Also clarifies what KconfigSyntaxError is doing:
- Commit 95515d4 ("Clarify that KconfigSyntaxError = KconfigError in
the docs").
|
|
Pro: Looks cleaner and matches how definitions are usually written.
Con: Makes it harder to discover that 'bool "foo"' is just shorthand for
'bool' + 'prompt "foo"' (though it's documented).
The pros probably win.
|
|
These are constant symbols, which is why the quotes showed up.
Special-case them to remove the quotes, to match what people expect.
Internally, n/m/y without quotes is taken as a shorthand for
"n"/"m"/"y".

Commit e81a77b ("Consistently put direct deps. last when propagating")
makes the position of the direct deps. in property conditions
predictable after dependency propagation, making it easy to strip them
as needed.
Use this to implement MenuNode.orig_{prompt,defaults,selects,implies,ranges},
which work like the non-orig_* versions but omit the direct deps. Use
those in turn to omit the direct deps in Symbol/Choice.__str__().
The direct deps. (with propagated parent deps.) can still be seen after
'depends on ...', so there is no loss of information.
This unclutters Kconfig definitions shown in menuconfig/guiconfig and in
any generated documentation. The old output also had duplicated
dependencies, though it doesn't matter for evaluation.
Before:
config A
bool
prompt "A" if DEP
default y if FOO && DEP
depends on DEP
After:
config A
bool
prompt "A"
default y if FOO
depends on DEP
|
|
Preparation for some later additions. Previously, the 'visible if' deps
appeared to the right of the 'depends on' deps. Now, the direct deps
always appear last.
With this change, the prompt tuple is only updated once for any given
menu node too, which should be a tiny bit faster.
|
|
Ye olde code.
|
|
KconfigSyntaxError is just an older (bad) name. pydoc generates
confusing documentation due to the "KconfigSyntaxError = KconfigError"
assignment, so mention it in the docstring.
|
|
Fixes a minor menuconfig interface bug in commit f962269 ("menuconfig:
Fix inconsistent top/bottom scroll offset due to off-by-one").
Some doc tweaks are included as well:
- Commit 841ab04 ("Mention that .config can be brought up-to-date via
menuconfig/guiconfig")
- Commit f8978b0 ("Say "removes" instead of "resets" in the
unset_value(s)() docstring")
|
|
Good to know.
|
|
Clearer.
|
|
The scroll offset when scrolling up was one more than when scrolling
down, due to an off-by-one.
|
|
Interpolate $(Kconfig) directly into the Python code and get rid of the
separate argument. This also gets rid of the old ipython workaround, and
might prevent similar gotchas in general.

- Commit aed7b40 ("Add guiconfig to PHONY in Makefile patch")
- Commit 50ded1d ("Make .config.old easier to discover")
|
|
Only appeared in two of the scripts, and main() is such a common
convention anyway.
|
|
Mention that the old version of an overwritten configuration file is
saved to <filename>.old in a few different places, to make it easier to
discover.
|
|
Oversight.

Not installed by default on many Linux systems, despite being part of
the Python standard library.

|
Improves dependency-related documentation a bit, in commit 95b80e1
("Clarify direct_dep and dep documentation").
|
|
- Mention that having no direct dependencies corresponds to having y
direct dependencies
- Remove the note about how direct_dep is used internally. It's also
used for the select-with-unsatisfied-deps warning.
- Remove the note about how checking direct_dep might be "redundant"
since it's propagated. direct_dep can be useful in scripts still, and
maybe it could scare people away from it.
- Say 'surrounding menus and ifs' instead of of 'parent' in the 'dep'
docstring
- Fix two s/config/kconfig/ typos
|
|
Improves documentation for the Symbol/Choice.referenced attribute, in
commit 814e2de ("Improve the 'referenced' docstring").
|
|
- Point out why dependencies from surrounding if's and menus are
included
- Clarify that .referenced isn't transitive. Only "direct" references
are included.
- Give a hint about direct dependencies and expr_items()

It's undocumented and unguessable that Kconfig.top_node.filename/linenr
gets set to the location of the 'mainmenu' statement (if any).
Always set it to the first line of the top-level Kconfig instead, which
should be more expected.
|
|
|
|
Move the global variable descriptions earlier, remove some redundant
comments, and clarify that the Python 3-only comment in setup.py is
talking about the terminal menuconfig.
|
|
Mostly to get things consistent with _update_jump_to_display().
|
|
Adds a Python 2/3-compatible GUI menuconfig, in commit 9be6b7b
("guiconfig: Add a Tkinter-based menuconfig").
See that commit and the updated README for a longer description.
|

This is a graphical configuration interface written in Tkinter. Like
menuconfig.py, it supports showing all symbols (with invisible symbols
in red) and jumping directly to symbols. Symbol values can also be
changed directly from the jump-to dialog.
When single-menu mode is enabled, a single menu is shown at a time, like
in the terminal menuconfig. Only this mode distinguishes between symbols
defined with 'config' and symbols defined with 'menuconfig'.
Compatible with both Python 2 and Python 3. Has been tested on X11,
Windows, and macOS.
To avoid having to carry around a bunch of GIFs, the image data is
embedded in guiconfig.py. To use separate GIF files instead, change
_USE_EMBEDDED_IMAGES to False. The image files can be found in
https://github.com/ulfalizer/Kconfiglib/tree/screenshots/guiconfig.
A new `make guiconfig` target in the Makefile patch will run the GUI
configuration interface on the Linux kernel.

Simplifies the filename calculation for .old files, in commit 4fed39d
("Never prepend '.' to $KCONFIG_CONFIG.old"). This makes it reliable to
refer to the backup file as $KCONFIG_CONFIG.old in scripts.
This is a backwards-incompatible change when $KCONFIG_CONFIG is set to a
filename that does not start with a '.', so the major version is
increased. Note that $KCONFIG_CONFIG is usually set to
<some path>/.config, so few people should be affected.
|
|
In retrospect, trying to be "helpful" by saving the old version of a
$KCONFIG_CONFIG that does not start with a '.' as e.g. '.config.old'
instead of 'config.old' is a bad idea, because it means that scripts
can't rely on the backup file simply being called $KCONFIG_CONFIG.old.
I spotted this causing compatibility issues in
https://github.com/automate-lfs/jhalfs/commit/a645174fd43ba4eee84089965df85785878e7aa6.
I had Vim backup files and the like in mind originally, but .config.old
is much more likely to be processed by scripts.
This is a small backwards compatibility break, so the major version will
be increased to 11.

Makes sync_deps() safe to use in threaded scripts, in commit a664a6d
("Avoid chdir()ing in sync_deps()").
|
|
Temporarily changing the working directory is iffy if threads are
involved, since other code will see the change. Seems like a generally
rude thing for a random library function to do.
dir_fd (open() relative to directory) is another option, but it's Python
3 only, only available on the low-level os.open() interface, and might
not be universally supported.

Fixes an obscure menuconfig display issue, in commit 4b387e0
("menuconfig: Fix display issue for unsatisfied-deps selected symbol
with children").
|
|
Says the same thing the comment above it says.
|
|
A symbol with unsatisfied direct dependencies can end up with visible
children in an implicit submenu if it is selected (though that generates
a warning), so the optimization in _shown_nodes() isn't safe, and causes
the child nodes to not be shown outside show-all mode.
Just remove the optimization. Trying things out some more, everything's
plenty fast enough anyway.
Checking the direct dependencies of the parent instead would be safe.

Adds a simple utility for initializing the configuration from an
existing configuration, in commit 4f1674f ("defconfig: Add script").
