Only show "real" (non-indented) menus, like in the menu path at the top.
|
|
This is consistent with how they're shown in the info dialog. Looks less
confusing for empty strings too.
|
|
Makes it double as a quick way to check if something is enabled.
Suggested by Randy Dunlap.

This gets rid of some slight input jerkiness while inputting e.g.
'.*debug' on my machine (though the '.*' is redundant there), due to
faster matching. The '.*' probably has bad interactions with
re.search(), which matches anywhere in the string.
A plain "debug" matches about 70% faster, though it's fast enough to
feel instant anyway.
|

|
|
Instead of doing a single search of the '<symbol name> "<prompt>"'
string. This avoids gotchas like '_DEBUG$' not matching FOO_DEBUG if
FOO_DEBUG has a prompt.

re.error.msg was added in Python 3.5. Show a generic error message when
it isn't available.
|
|
This makes it clearer when an edit box is scrolled, especially when
backspacing. The cursor will now only go to the far left/right of the
edit box at the start/end of the string.
Reuse _SCROLL_OFFSET to specify the scroll offset.
|
|
List the working directory, which might not be obvious, and support
referring to the home directory with ~.
Support for multiple lines of help text in input dialogs was added as
well.

Since commit cbf32e2 ("Expand environment variables in strings
directly"), Kconfiglib expands environment variables directly in strings
instead of using the 'option env=...' mechanism (this is planned for the
C tools too). This new behavior is backwards-compatible as long as all
'option env=...' symbols have the same name as the environment variables
they reference.
Warn if 'option env="FOO"' appears on a symbol that isn't named FOO, to
point out compatibility issues and help with debugging.
|
|
This code is surprisingly hot.
|
|
The Kconfig definition already lists the location and menu path, and now
shows up at the top.
|
|
Only a single caller left now, in a hot loop.
|
|
Also strip the prompt in that case. Leading/trailing whitespace in
prompts leads to ugly workarounds in e.g. reStructuredText
documentation, where '*prompt *' is invalid.
|
|
UNAME_RELEASE is expanded in one of the 'default's of the DEFCONFIG_LIST
symbol in the Linux kernel. This broke after "$FOO" was changed to
directly expand to the value of the environment variable FOO, rather
than to the value of the symbol FOO.
Restore compatibility with a small wrapper.

Automatically turn on show-all mode if the currently selected node
becomes invisible after loading the new configuration.
Show an are-you-sure dialog if there are unsaved changes.
A wart here is that there currently isn't a way to get 'errno' and
'strerror' from the IOError exception returned by load_config(). Hack
around it by opening the configuration file separately with open()
first, just to catch any obvious errors.

Don't show A in the menu path at the top when entering the menu "B"
below, which will be indented relative to A. It looks confusing, and can
lead to really long menu paths.
config A
bool "A"
menu "B"
depends on A
...
|
|
This is less twisty, and generates slightly smaller bytecode. Probably
doesn't help to special-case the first line.
|
|
More readable.
|
|
Now that environment variables are expanded directly with
os.path.expandvars(), "$SRCARCH" will be kept as is if SRCARCH isn't
set. arch/$SRCARCH/Kconfig won't exist, unlike arch//Kconfig.

Get rid of some code duplication.

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).

Make "$FOO" directly reference the environment variable $FOO in e.g.
'source' statements, instead of the symbol FOO. Use os.path.expandvars()
to expand strings (which preserves "$FOO" as-is if no environment
variable FOO exists).
This gets rid of the 'option env' "bounce" symbols, which are mostly
just spam and are buggy in the C tools (dependencies aren't always
respected, due to parsing and evaluation getting mixed up). The same
change will probably appear soon in the C tools as well.
Keep accepting 'option env' to preserve some backwards compatibility,
but ignore it when expanding strings. For compatibility with the C
tools, bounce symbols will need to be named the same as the environment
variables they reference (which is the case for the Linux kernel).
This is a compatibility break, so the major version will be bumped to 6
at the next release.
The main motivation for adding this now is to allow recording properties
on each MenuNode in a clean way. 'option env' symbols interact badly
with delayed dependency propagation.
Side note: I have a feeling that recording environment variable values
might be redundant to trigger rebuilds if sync_deps() is run at each
compile. It should detect all changes to symbol values due to
environment variables changing value.

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.
|

Should probably move the screenshots out into a separate section soon.

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.
|
|
Enough people have run into exceptions due to running in the C locale
that it seems worthwhile.
Add a new 'encoding' parameter to Kconfig.__init__() that specifies the
encoding to use and make it default to "utf-8". Passing None gives the
old behavior of using the encoding specified in the environment.
