2018-11-27hush: allow hush to run embedded scriptsRon Yorston
Embedded scripts require a shell to be present in the BusyBox binary. Allow either ash or hush to be used for this purpose. If both are enabled ash takes precedence. The size of the binary is unchanged in the default configuration: both ash and hush are present but support for embedded scripts isn't compiled into hush.

2018-06-06restore documentation on the build config languageKartik Agaram
Kconfig-language.txt was deleted in commit 4fa499a17b52b back in 2006. Move to docs/ as suggested by Xabier Oneca: http://lists.busybox.net/pipermail/busybox/2014-May/080914.html Also update references to it everywhere.

2017-01-06ash: explicltly group ash optionsKang-Che Sung
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".

2017-01-04shell: clarify help text of CONFIG_{SH,BASH}_IS_* optionsKang-Che Sung
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.)

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>
2016-07-22config: disentangle PREFER_APPLETS from SH_STANDALONE and SH_NOFORKDenys Vlasenko
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>
