Menuconfig has a feature where you can "press the key in the (#) prefix to jump directly to that location. 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 <Mr.Bossman075@gmail.com> --- 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. --- scripts/kconfig/nconf.c | 111 ++++++++++++++++++++++++++++++++---- scripts/kconfig/nconf.gui.c | 27 +++++++-- scripts/kconfig/nconf.h | 4 ++ 3 files changed, 127 insertions(+), 15 deletions(-)
