From 98e5a1579e7d34fe3803240750a1c48efcd9cb15 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 24 Jul 2006 21:40:46 +0200 Subject: kconfig/lxdialog: refactor color support Clean up and refactor color support. All color support are now in util.c including color definitions. In the process introduced a global variable named 'dlg' which is used all over to set color - thats the reason why all files are changed.

With this patch lxdialog is now built-in. It is loosly based om previous work by: Petr Baudis Following is a list of changes: o Moved build of dialog routings to kconfig Makefile o menubox + checklist uses a new item list to hold all menu items o in util.c implmented helper function to deal with item list o menubox now uses parameters to save scroll state (avoids temp file) o textbox now get text to be displayed as parameter and not a file o make sure to properly delete subwin's before main windows o killed unused files: lxdialog.c msgbox.c o modified return value for ESC to match direct calling o in a few places the code has been adjusted to 80 char wide o in textbox a small refactoring was made to make code remotely readable o in mconf removed all unused stuff (functions/variables) Following is a list of know short comings: a) pressing ESC twice will be interpreted as two ESC presses b) resize does not work. menuconfig needs to be restarted to be adjusted Signed-off-by: Sam Ravnborg --- scripts/kconfig/Makefile | 23 +- scripts/kconfig/lxdialog/Makefile | 21 -- scripts/kconfig/lxdialog/checklist.c | 136 ++++------ scripts/kconfig/lxdialog/dialog.h | 52 +++- scripts/kconfig/lxdialog/inputbox.c | 2 +- scripts/kconfig/lxdialog/lxdialog.c | 204 --------------- scripts/kconfig/lxdialog/menubox.c | 95 +++---- scripts/kconfig/lxdialog/msgbox.c | 72 ------ scripts/kconfig/lxdialog/textbox.c | 298 +++++----------------- scripts/kconfig/lxdialog/util.c | 134 +++++++++- scripts/kconfig/lxdialog/yesno.c | 2 +- scripts/kconfig/mconf.c | 482 ++++++++++------------------------- 12 files changed, 502 insertions(+), 1019 deletions(-) delete mode 100644 scripts/kconfig/lxdialog/Makefile delete mode 100644 scripts/kconfig/lxdialog/lxdialog.c delete mode 100644 scripts/kconfig/lxdialog/msgbox.c (limited to 'scripts/kconfig/lxdialog/textbox.c') diff --git a/scripts/kconfig/Makefile b/scripts/kconfig/Makefile index a90d3cc76bfa..b2928f039c17 100644 --- a/scripts/kconfig/Makefile +++ b/scripts/kconfig/Makefile @@ -11,7 +11,6 @@ gconfig: $(obj)/gconf $< arch/$(ARCH)/Kconfig menuconfig: $(obj)/mconf - $(Q)$(MAKE) $(build)=scripts/kconfig/lxdialog $< arch/$(ARCH)/Kconfig config: $(obj)/conf @@ -81,6 +80,23 @@ help: @echo ' allyesconfig - New config where all options are accepted with yes' @echo ' allnoconfig - New config where all options are answered with no' +# lxdialog stuff +check-lxdialog := $(srctree)/$(src)/lxdialog/check-lxdialog.sh + +# Use reursively expanded variables so we do not call gcc unless +# we really need to do so.

When lxdialog became built-in pressing <ESC> once would cause one step back and pressing <ESC><ESC> would cause two steps back. This patch - based on concept from Roman Zippel <zippel@linux-m68k.org> - makes one <ESC> a noop and pressing <ESC><ESC> will cause one step backward. In addition the final yes/no dialog now has the option to go back to the the kernel configuration. So if you get too far out you can now go back to configuring the kernel without saving and starting all over again.
