You will be returned to the current search results after exiting this new menu." This commit adds this feature to nconfig, with almost identical code. Signed-off-by: Jesse Taube --- v1->v2: Add selected_conf to go to menu and select a specific option. Use get_line insead of creating new function. Use Masahiro Yamada's new jump search implementation. v2->v3: Change `start, end` to size_t and move scope to if Removed redundant assigment of `again` to false. --- scripts/kconfig/nconf.c | 111 ++++++++++++++++++++++++++++++++---- scripts/kconfig/nconf.gui.c | 27 +++++++-- scripts/kconfig/nconf.h | 4 ++ 3 files changed, 127 insertions(+), 15 deletions(-) diff --git a/scripts/kconfig/nconf.c b/scripts/kconfig/nconf.c index 3ba8b1af390f..172dc8fdd3ef 100644 --- a/scripts/kconfig/nconf.c +++ b/scripts/kconfig/nconf.c @@ -220,7 +220,7 @@ search_help[] = "Location:\n" " -> Bus options (PCI, PCMCIA, EISA, ISA)\n" " -> PCI support (PCI [ = y])\n" -" -> PCI access mode ( [ = y])\n" +"(1) -> PCI access mode ( [ = y])\n" "Selects: LIBCRC32\n" "Selected by: BAR\n" "-----------------------------------------------------------------\n" @@ -231,9 +231,13 @@ search_help[] = "o The 'Depends on:' line lists symbols that need to be defined for\n" " this symbol to be visible and selectable in the menu.\n" "o The 'Location:' lines tell, where in the menu structure this symbol\n" -" is located.
