[Question] Best practices with choices and help in kas menu #102

Closed jmillscnhind closed 1 year ago

First off awesome project. sorry if this is in the wrong place Anyways....

Ive been playing around with the menu system. When making choices in the past I do the following.

Question 1 choice via menu

config HAVE_FOO
    bool

config HAVE_BAR
    bool

choice
    prompt  "foo or bar ?"
    default HAVE_FOO
    depends on HAVE_FOO || HAVE_BAR
config TARGET_FOO
    bool "select foo options"
    depends on HAVE_FOO 

 # add bar 
 endchoice

 KAS_INCLUDE_FOO
    string
    depends on HAVE_FOO
    default "kas/foo.yml"

It seems that I can not use the inter depends on on the choice. so the alternative I use select

    config TARGET_FOO
        bool "select foo options"
        select HAVE_FOO

Is there a better way or a example of how to use choice in the Kconfig for kas?

Question 2 help in the menu.

    config TARGET_FOO
        bool "select foo"
        default y
        help
           Say Y here if you would like too ....

I seen this[1] but can not seem to invoke(? or button) the help section. Any advice would be great.

We should be compatible with https://www.kernel.org/doc/html/latest/kbuild/kconfig-language.html as we are using a library that aims at this. And that means, you can make a choice element depend on things but not the complete choice group.

Regarding help: This generally works, check existing examples like https://github.com/siemens/meta-iot2050/blob/master/Kconfig. The example excerpt you shared should work as well, though.
