`di` is a highly portable program to display disk information.
It features the ability to display the disk usage in the format you prefer.

The 'di' Tcl interface 
provides a 'diskspace' command that returns a dictionary with
the filesystem information.

The dictionary returned is nested and keyed by the mount point.
The dictionary keys are: device, fstype, total, free, available, totalinodes, freeinodes, availableinodes, mountoptions, display.

The total, free and available space are returned as bytes.

'display' is returned when the `di` format specifier is not empty.  The data returned is a list of the display items.

Any of the `di` options may be used to change the data returned in the 'display' key.  See the `di` manual page for the complete list.

Example usage:
======
% package require diskspace

% set di [diskspace -f {} /] ; # get only the basic information for root filesystem
/ {device /dev/sda1 fstype ext4 total 485893496832 free 269818650624 available 245113102336 totalinodes 30138368 freeinodes 29762805 % availableinodes 29762805 mountoptions rw,errors=remount-ro}

% set di [diskspace -f {up} /] ; # also get the used space and percentage used.
/ {display {201.2G      50%} device /dev/sda1 fstype ext4 total 485893496832 free 269818736640 available 245113188352 totalinodes 30138368 freeinodes 29762805 availableinodes 29762805 mountoptions rw,errors=remount-ro}
% lassign [dict get $di / display] useddisplay percused

% set di [diskspace -d 1 -f up /] ; # instead, get the used value in bytes.
/ {display {216074854400        50%} device /dev/sda1 fstype ext4 total 485893496832 free 269818642432 available 245113094144 totalinodes 30138368 freeinodes 29762805 availableinodes 29762805 mountoptions rw,errors=remount-ro}
% lassign [dict get $di / display] usedbytes percused

% set di [diskspace -f {}] ; # get information on the usual list of filesystems.

To build the Tcl extension:

Most systems:
    cd C; make -e tcl-sh

Windows Cygwin:
    cd C; make -e CC=gcc NO_PIE=T tcl-sh

Windows Msys:
    cd C; make -e WINAPI=T NO_PIE=T LDFLAGS_SHARED="-static-libgcc" di-sh.env di.env
    make -e WINAPI=T tcl-sh
