Traditionally, a command is a piece of perl that is a simple
in line lump of code e.g (blank.pl):
my ($self, $line) = @_;
my $lines = 1;
my $data = ' ';
my @f = split /\s+/, $line;
if (@f && $f[0] !~ /^\d+$/) {
$data = shift @f;
$data = $data x int(($self->width-1) / length($data));
$data .= substr $data, 0, int(($self->width-1) % length($data))
}
if (@f && $f[0] =~ /^\d+$/) {
$lines = shift @f;
$lines = 9 if $lines > 9;
$lines = 1 if $lines < 1;
}
my @out;
push @out, $data for (1..$lines);
return (1, @out);
It is now possible to have a 'handler' and any other code you like in
a command file, for instance (again blank.pl):
sub this {}
sub that {}
sub another {}
sub handle
{
my ($self, $line) = @_;
my $lines = 1;
my $data = ' ';
my @f = split /\s+/, $line;
if (@f && $f[0] !~ /^\d+$/) {
$data = shift @f;
$data = $data x int(($self->width-1) / length($data));
$data .= substr $data, 0, int(($self->width-1) % length($data))
}
if (@f && $f[0] =~ /^\d+$/) {
$lines = shift @f;
$lines = 9 if $lines > 9;
$lines = 1 if $lines < 1;
}
my @out;
push @out, $data for (1..$lines);
return (1, @out);
}
The 'sub handle' being the cue that distiguishes one form from the other.
The first form has the 'sub handle { <code> }' wrapped around it so, internally
they are treated the same. Each command is placed in its own DXCommandmode sub
package with a standard set of packages "use"d in front of it.
For now (at least) any functions you declare are just that. "$self" is a DXCommandmode
not a blessed reference to this command's full package name, you cannot use things like
$self->this() or $self->that()
they must be called as local functions.
This may change in the future.
