| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This would makes all ash options indented inside "ash" in menuconfig. It appears that menuconfig has a limit at tracking multiple dependency lines like this (it looks like a "diamond problem" but I'm not sure if it is): ---ASH <---------- / \ ASH_OPTIMIZE_FOR_SIZE !NOMMU <-*----SH_IS_ASH <----[OR] <--ASH_INTERNAL_GLOB \ / ASH_RANDOM_SUPPORT ---BASH_IS_ASH <-- [...] The kconfig-language document [1] states that: > If a menu entry somehow depends on the previous entry, it can be > made a submenu of it. First, the previous (parent) symbol must be > part of the dependency list and then one of these two conditions > must be true: > - the child entry must become invisible, if the parent is set to 'n' [BusyBox ash used to satisfy this, but no longer does] > - the child entry must only be visible, if the parent is visible [BusyBox ash configs actually satisfy this, but because of "diamond" above this might not be easily detected] So I found out a direct workaround: by making ash options explicitly depend on !NOMMU, we can tell menuconfig that rule 2 above is satisfied without any more tracking. --------------------- / \ !NOMMU <-*-----ASH <-------- \ \ \ \ ASH_OPTIMIZE_FOR_SIZE *---SH_IS_ASH <---[OR]-[AND] <--ASH_INTERNAL_GLOB \ / ASH_RANDOM_SUPPORT --BASH_IS_ASH <- [...] So all ash options would now be indented under "ash".

* shell: clarify help text of CONFIG_{SH,BASH}_IS_* optionsKang-Che Sung2017-01-041-1/+22
| | | | | | | | | | | | | Mention the behavior if user selects CONFIG_SH_IS_ASH but not CONFIG_ASH. We will be explicit that invocations like "busybox ash" will not work for such configuration. Also clarify help text of CONFIG_BASH_IS_* that bash compatibility in ash is not complete. (It shouldn't be anyway - ash can't support every bash quirk out there.)

* Make it possible to select "sh" and "bash" aliases without selecting ash or hushDenys Vlasenko2016-12-231-24/+21
| | | | | | | The same can be done for msh, but we are probably better off just deleting it in a next versio or two. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | On user request. I thought enabling/disabling them all together is more consistent. Evidently, some people do want them to be separately selectable. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
