NAME
Term::ReadLine::Perl5 - A pure Perl implementation GNU Readline
SYNOPSIS
use Term::ReadLine::Perl5;
$term = new Term::ReadLine::Perl5 'ProgramName';
while ( defined ($_ = $term->readline('prompt>')) ) {
...
}DESCRIPTION
Overview
This is a implementation of the GNU Readline/History Library written entirely in Perl.
GNU Readline reads lines from an interactive terminal with emacs or vi editing capabilities. It provides as mechanism for saving history of previous input.
This package typically used in command-line interfaces and REPLs (Read, Eval, Print Loops).
SUBROUTINES
Term::ReadLine::Perl-new($name, [*IN, [*OUT])>
Returns a handle for subsequent calls to readline functions.
$name is the name of the application.
Optionally you can add two arguments for input and output filehandles. These arguments should be globs.
This routine might also be called via Term::ReadLine-new($term_name)> if other Term::ReadLine packages like Term::ReadLine::Gnu is not available or if you have $ENV{PERL_RL} set to 'Perl';
At present, because this code has lots of global state, we currently don't support more than one readline instance.
Somebody please volunteer to rewrite this code!
MinLine([$minlength])
If $minlength is given, set $readline::minlength the minimum length a $line for it to go into the readline history.
The previous value is returned.
AddHistory
AddHistory($line1, ...)
Place @_ at the end of the history list unless the history is stifled, or there are already too many items.
clear_history
clear_history()
Clear or reset readline history.
remove_history
remove_history($which)
Remove history element $which from the history. The removed element is returned.
replace_history_entry
replace_history_entry($which, $data)
Make the history entry at $which have $data. This returns the old entry. In the case of an invalid $which, $<undef> is returned.
stifle_history
stifle_history($max)
Stifle or put a cap on thethe history list, remembering only $max number of lines.
unstifle_history
unstifle_history
Unstifle or remove limit the history list.
Theprevious maximum number of history entries is returned. The value is positive if the history was stifled and negative if it wasn't.
history_is_stifled
history_is_stifled
Returns true if saved history has a limited (stifled) or false if there is no limit (unstifled).
