This allows accurate documentation to be generated for symbols and
choices defined in multiple locations. There are now MenuNode.defaults,
MenuNode.selects, etc., lists that mirror the corresponding
Symbol/Choice lists.
Symbol/Choice.__str__() now correctly show property locations as well,
by simply concatenating the strings returned by MenuNode.__str__() for
each node.
_parse_properties() was modified to add all properties directly to the
menu node instead of adding them to the contained symbol or choice. The
properties are then copied up to symbols and choices in
_finalize_tree(). Dependency propagation is handled at the same time.
As a side effect, this cleans up the code a bit and de-bloats
_parse_properties().
Update the menuconfig implementation to use the new functionality. It
now lists the menu nodes for symbols and choices with the correct
properties for each node (previously, all defaults, selects, implies,
and ranges appeared on the first definition).

Was using an older name.

Works like in readline/Vim.

The cache was broken due to using an old variable name.
Piggyback a neat trick for storing globals in default arguments that I
had missed until now.

Search and display prompts for menu nodes that have them. They often
contain useful strings.
Add a pre-search pass that generates a string to search/display for each
menu node, to allow the search regex(es) to run over a single string.
That also makes 'foo bar' match for a symbol that has 'FOO' in its name
and 'bar' in its prompt, which is handy.
Remove the '(in menu X)' string that was added previously for symbols
defined in multiple locations. You'd usually be able to tell which menu
node is which from the (lack of) prompt.

A search like 'host usb' now finds all symbol names that match both
'host' and 'usb' (as regular expressions), including e.g. USB_MTU3_HOST.
This saves typing a bunch of '.*' and makes it easier to find symbols
when you aren't sure what order the components appear in.

Cleaner to do it in _menuconfig(), as it makes the fullscreen dialogs
fully independent. Saves some code too.
|
|
Might have made it sound like _parent_menu() returns a list.
|
|
Air some long conditionals out a bit. Be more consistent with format().
|
|
Can't get { } since {} implies n isn't assignable.

The horizontal scroll (hscroll) wasn't initialized properly when the
initial (prefilled) contents of an edit box was longer than the edit box
itself (e.g. when saving with a long path in KCONFIG_CONFIG). Things
snapped back into place once a key was pressed.
Initialize hscroll properly to fix the initial rendering.

If LC_CTYPE is set to the C locale, try to convert it to a UTF-8 locale.
Use a list of commonly available UTF-8 locales. Give up and use the C
locale if none of them are available.
This fixes curses Unicode I/O issues on systems with bad defaults:
ncurses configures itself from the locale settings, and the C locale
implies ASCII.
The logic mirrors https://www.python.org/dev/peps/pep-0538/. I took the
list of locales to try from the CPython code (in Python/pylifecycle.c).

Makes it easier to see the menu structure.
Make the indent configurable via a _SUBMENU_INDENT configuration
variable.

Pressing [/] brings up a dialog with an edit box where a regex can be
entered. The list of matching symbols is always shown below it.
Selecting a symbol and pressing [Enter] jumps directly to it in the menu
tree. If the symbol is invisible, show-all mode is turned on
automatically.
This commit also includes a bunch of more-or-less unrelated changes from
poking around with the code:
- Some redundant styles were merged. Probably wouldn't want to have a
different style for each separator line, for example...
- [ESC] in the top menu now works like [Q]
- Returning to a parent menu now makes sure that the selected row is
visible, even if the terminal was shrunk between entering the child
menu and leaving it.
- A _max_scroll() helper was factored out to reduce code duplication.
It takes a list of items and a window in which the list is
displayed, with one row per item, and returns the minimum scroll
value that will make the final item visible.
- The save dialog now pops up a message to confirm that the save was
successful.
- Lots of minor code nits all over (renamings, etc.)

Previously, the title of the current menu disappeared off the right edge
of the terminal for long menu paths. Scroll the menu path to the right
if needed to make sure it is always shown.

Don't bother to show the save-and-quit dialog.
Also quit immediately if the configuration hasn't been changed since the
last time it was explicitly saved with the save dialog.
Rename _set_node() to _set_node_tri_val(), as the old name gets
confusing with the new _set_val() function.

Works the same as in mconf.

When show-all mode is enabled, all items in the current menu are shown,
including promptless and invisible items. Promptless items are shown
with their name within <> brackets in place of the prompt.
This will make it possible to jump to invisible items once the jump-to
feature is added. It is also a handy feature on its own.
.config loading from within the interface will make use of it as well,
in case the current menu becomes complete invisible.
Piggyback various code cleanups. Rename _visible* to _shown*, as it now
includes invisible items in show-all mode.

Uses the 'curses' module, which is in the Python standard library. Only
Python 3 is supported, mostly due to Unicode support.
Windows support is provided through an external package which adds
support for the 'curses' module on Windows.
See the changes and the docstring in the newly added menuconfig.py for
more information.
Piggyback a README notes mentioning that Kconfiglib supports Unicode.
