Hi,
After submitting this PR (https://github.com/apache/nuttx/pull/18418),
I wondered if there were more of these "ghost selects".
So with these commands (thank you Claude) I created a list:
# get all config, menuconfig and choice items
find . -name 'Kconfig*' | xargs grep -hE
'^\s*(config|menuconfig|choice)\s+\S' | awk '{print $2}' | sort -u >
/tmp/kconfig_syms.txt
# get all select items
find . -name 'Kconfig*' | xargs grep -h '^\s*select ' | awk '{print
$2}' | sort -u > /tmp/kconfig_select_syms.txt
# compare files with some magic option
comm -23 /tmp/kconfig_select_syms.txt /tmp/kconfig_syms.txt
Results down below.
Searching these items in the code repo confirms they (at least the
ones I checked) are similar "ghost selects". Ie selected configuration
items which result in nothing.
Should we remove them to clear up the clutter? What test approach is advised?
Cheers,
Maarten
