PrintControl(3pm)
NAME
PDL::Perldl2::Plugin::PrintControl - disable default print output
SYNOPSIS
> $a = 3;
3
> $_REPL->load_plugin('PDL::Perldl2::Plugin::PrintControl');
> $a;
> $_REPL->print_by_default(1);
1
> $a;
3
DESCRIPTION
By default the Devel::REPL always prints the results of its evaluation.
This is fine for small objects but for things like large data objects
(e.g. a 100x100 matrix in PDL) the result can be hundreds of lines of
output for each command.
This plugin disables the default print output and adds an attribute
with accessor method "print_by_default" which can be used to toggle the
print default on or off.
METHODS
- print_by_default
- By default, the "PrintControl" plugin sets "print_by_default" to 0
(false), which disables automatic printing of results. Call the
print_by_default accessor with a 1 (true value) to enable default
printing. - do_print
- This is a convenience accessor for the print_by_default attribute. If
you call this method without a value, it toggles the current setting.
Otherwise, it just sets print_by_default to the value.
