Hi,
In the current cfdisk, when making a new partition in a free space,
the program prompts for the partition size, with a suggested value
already filled in and the cursor sitting at the end of that value.
If one tries to use the cursor-left key to edit the value, in a utf8
locale this produces the character Ą instead of a bell. (The same
happens when cfdisk asks for the name of a script file.)
To reproduce: # LC_ALL=en_US.utf8 ./cfdisk
Anyway, if the cursor keys would not produce weird characters,
and they can't be made to work normally (that is: to go left and
right), then the only way to change the suggested value is to use
the Backspace key. This is awkward. The older cfdisk, when it
prompted for a partition size, would put the cursor at the start
of the suggested value, and hitting any other key than Enter
would erase this value. That is nice and desirable behaviour.
Could that be restored?
Also, upon startup the old cfdisk would put the cursor on the
menu item "Quit", showing the user the most important thing
right at the start: how to get out. This is extra useful when
cfdisk is localized to another language where the word for quit
doesn't start with a Q. Could this initial menu-item selection
be restored?
Something quite different: the man page of cfdisk says that it
is possible to load an sfdisk-compatible script into cfdisk.
But how?
Benno

Yeah, I think that's the behaviour I've seen from other packages. When built without readline, they just leave the tty in cooked mode, so a line of input becomes read(2)able when the user presses return. I guess cfdisk already has an arrow-key driven UI, so the wrapper for readline (that compiles to a fallback #ifndef HAVE_READLINE) would have to put the tty in/out of cooked mode. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

Fixed, now there is "preferred key" for each menu, "New" for free space and "Quit" for the rest.
