I want to get the screen width and cursor positions.
When I used curses, all the screen content was cleared.
So Can I use curses to get the screen size without clearing anything in the window?
Or is there any other alternative???
I can use only C or C++. (0 Replies)

Hi to all!
I'm a teacher of maths and physics in an italian high school in Milan, Italy.
I need a simple program that read the position of mouse cursor in function of time and write the coordinates in a text file. The time resolution have to be something like 1/10 sec or better (I have to know... (2 Replies)
hi all,
am trying to modify a ksh script to group server names together depending on the cluster they sit in. currently the script does a

I need to get the cursor position, and put it inside a variable. Problem is, i don't have the tput command, or ncurses.
Apparently I was supposed to try the following:
echo -e '\E
But I don't get a value or anything. Please help. (3 Replies)
Hi there.
It's easier to explain this with a pseudo code, I hope this makes sense:
var1=hello
echo $var1
some kind of loop
echo loop counter
done
How do I hold the cursor position immediately behind the last output so I'd get something like:
hello123456789
DOS used to use ","... (5 Replies)

Net::CLI::Interact::Role::Iterator(3pm) User Contributed Perl Documentation Net::CLI::Interact::Role::Iterator(3pm)NAME
Net::CLI::Interact::Role::Iterator - Array-based Iterator
VERSION
version 1.121640
SYNOPSIS
my $count = $iter->count;
$iter->reset;
while ( $iter->has_next ) {
print $iter->next;
}
DESCRIPTION
This module implements an array-based iterator which may be mixed-in to add management of a sequence of elements and processing of that
sequence.
The iterator is inspired by MooseX::Iterator but limited to arrays and adds many other facilities. The following section describes the
methods provided by this class.
USAGE
The slot used for storing iterator elements is named "_sequence" and you should write your consuming class to marshall data into this slot,
perhaps via "BUILD" or "init_arg". For example:
has '+_sequence' => (
isa => 'ArrayRef[Thingy]',
init_arg => 'things',
);
INTERFACE
count
The number of elements currently stored in the iterator. Note that this is of course not the same as the index of the last item in the
iterator (which is 0-based)
first
Returns the first item in the iterator.
last
Returns the last item in the iterator.
item_at( $pos )
Returns the item at the given position in the iterator, or throws an exception if $pos is past the end of the iterator. The position is
0-based.
insert_at( $pos, $iter )
Inserts the contents of the passed iterator starting at (not after) the position given. The passed iterator must also be a consumer of this
role. The position is 0-based.
append( $iter )
Shorthand for "insert_at" when you want to add the contents of the passed iterator after the end of the sequence.
idx( $pos? )
Returns the index (0-based) of the current iterator cursor, or sets the cursor if a position (again, 0-based) is passed.
An exception is thrown if you attempt to read the cursor position before having read any elements from the iterator, or if the iterator is
empty.
next
Returns the next item in the iterator sequence, and advances the cursor. Throws an exception if you have already reached the end of the
sequence.
has_next
Returns true if there are further elements to be read from the iterator.
peek
Returns the next item in the sequence without advancing the position of the cursor. It returns "undef" if you are already at the end of the
sequence.
reset
Resets the cursor so you can iterate through the sequence of elements again.
