This allows some symbol values to be forced while running
all{def,no,yes,mod}config.py. See Documentation/kbuild/kconfig.txt in
the Linux kernel.
Add a helper function load_allconfig() to Kconfiglib to avoid code
duplication in the tools.
Also add functions for enabling/disabling the warning that's generated
when a symbol is assigned multiple times in a (set of) .config files and
the values differ. It should be disabled when merging the
KCONFIG_ALLCONFIG configuration file. Previously, only the warning
generated when the assigned values are identical could be disabled.
Disable all warnings related to assigning a symbol multiple times in
examples/merge_config.py as well.

|
Consistently indent with tabs, like in the actual output.
|
|
Do the PEP 8 ordering thingy with standard library imports first.
|
|
Style nits.
|
|
Simplifies the code. Should promote new APIs.
Also fix list_undefined.py for recent kernels. More environment
variables are referenced now.
|
|
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.

Suggested by Mitja Horvat (pinkfluid) in
https://github.com/ulfalizer/Kconfiglib/pull/50.
Kconfig.node_iter() iterates through all menu nodes in the menu tree in
Kconfig order. This saves scripts the trouble of implementing their own
tree walking code.
Have node_iter() take a 'unique_syms' flag that can be enabled to only
include symbols defined in multiple locations once. This is often what
you want when generating output (and is used by write_config()). Order
is still preserved.
Piggyback a fix to a syntax error test comment. Parsing has been
tightened up now.
|
|
These are the same as Kconfig.defined_syms and Kconfig.choices, except
duplicates are removed. Kconfig order is still preserved.
This is almost always what you want when iterating through symbols and
choices, as it potentially saves work, avoids generating duplicates when
writing output, and still preserves Kconfig order for readability.
The old attributes will be kept for backwards compatibility (maybe
there's some rare cases where they could be useful too). They're created
internally anyway.
|
|
Much of the functionality is available in Kconfiglib itself now. Use the
new APIs to implement the examples in a much simpler way.
|
|
Handy e.g. when searching.
|
|
Move to the root, simplify a bit, provide an entry point function (for
setuptools's entry_points).
|
|
Could do something similar to allnoconfig.py for the packaged version.
|
|
Put to-be-packaged stuff in the root.
Use allnoconfig_simpler.py, and rename allnoconfig.py to
allnoconfig_walk.py and keep it as an example.
|
|
All the packaged code will appear in the root.
|
|
setuptools' 'entry_points' gives nice behavior on Windows. It requires
that the module has an entry point function. Create one and move the
command line argument handling to it.
Piggyback KCONFIG_CONFIG support, and make the script executable
(oversight).
|
|
This matches the C tools. Hadn't noticed they had the same feature.
|
|
Had missed sys.exit(msg).
|
|
To avoid confusing it with the new terminal menuconfig implementation.
Clean up the README a bit at the same time, removing some stuff that's
less essential now (e.g. the menuconfig_example.py "screenshot").
|
|
- Rename to name_and_loc(), to be consistent with the kconfiglib.py
version
- Use a comment instead of a docstring. Shorten the description a bit
too.
- Piggyback a missing # in conf3 in the module docstring. Typo.
|
|
Works like menuconfig.py, but just dumps the tree, with a specified
.config file as base. Handy for diffing.
|
|
- Use generator expression rather than list comprehension
- Fix dubious English
|
|
|
|
Piggyback a small note to clarify that symbols defined without a type
are pretty obscure.
|
|
|
|
|
|
|
|
|
|
It makes sense to prompt for a choice during oldconfig if it contains
new visible symbols, even if there is already an old visible user
selection.
|
|
Helpful for debugging.
Piggyback some small fixes:
- Don't imply that merge_config.py is an executable file or that it
only runs under Python 3. Remove the hashbang line and fix the
example in the overview.
- Add some #'s to the overview .config files that had accidentally been
left out.
- Fix a questionable sentence in oldconfig.py's name_and_loc_str()
docstring.
|
|
More experience working with the API convinced me that it's worth it.
Gets rid of ugly conversions in the menuconfig.py and oldconfig.py
examples, and streamlines some things internally as well.
Include two other small fixes as well:
- Make warnings generated by Choice.set_value() match those generated
by Symbol.set_value().
- Get rid of the input stripping in menuconfig.py. It's not like the
interface is usable as-is anyway, and it just complicates the
example.

Typing '??' displays the help text of the current item.
|
|
Not sure why anyone would want to oldconfig just a part of the
configuration tree, especially as there might be dependencies pointing
outside of it. Take a Kconfig object instead of a node.
|
|
The oldnoconfig operation needs to be rerun if the value of any symbol
changes, to catch cases where symbols depend on symbols defined after
them. Otherwise the earlier symbols will just get their default value
instead of being prompted for.
|
|
The examples had some leftovers from Kconfiglib 1.
|
|
Implements the standard 'make oldconfig' functionality, prompting the
user for the values of new symbols to update an old .config file.
This came up in
https://github.com/zephyrproject-rtos/zephyr/issues/5426.
|
|
Does a global search over all architectures in the kernel, which should
avoid false positives.
Referencing an undefined symbol in a particular architecture can be fine
in a Kconfig file that's shared by multiple architectures, but if the
symbol isn't defined by any architecture, it's likely to be an error (or
a potential cleanup).
|
|
Functions similarly to scripts/kconfig/merge_config.sh from the kernel.
Came up in https://github.com/zephyrproject-rtos/zephyr/pull/5417.
|
|
Copy-paste error.
Piggyback error message consistency nit for help_grep.py.
|
|
|
|
- Remove redundant parentheses in indent_print().
- Use unnumbered replacement fields with format().
|
|
Leftovers
|
|
No need to use a dictionary.
|
|
Preferred method, should 'option modules' be properly supported later.
|
|
Clean up some formatting a bit too.
|
|
Pointless as an optimization here. Should restrict obfuscating
micro-optimization to the library code too even where it helps.
|
|
Confirms that all the examples that aren't tested in the test suite at
least run. Easy to miss brokenness there. Output can be inspected
manually (it'll vary depending on the kernel version).
Fix defconfig_oldconfig.py, which hadn't been properly updated for the
new API.
|
|
|
|
Turns out to be kinda awkward to implement print_tree.py iteratively,
because the indent.
|
|
conf -> kconf, for consistency, plus various nits.
|
|
Can be implemented in a simpler/better way with Choice.assignable.
Also rename 'conf' to 'kconf' in allnoconfig.py for consistency.
