devel::repl::plugin::readlinehistory
Devel::REPL::Plugin::ReadLineHistory(3pm) User Contributed Perl Documentation Devel::REPL::Plugin::ReadLineHistory(3pm)
NAME
Devel::REPL::Plugin::ReadLineHistory - Integrate history with the facilities provided by Term::ReadLine
DESCRIPTION
This plugin enables loading and saving command line history from a file as well has history expansion of previous commands using the
!-syntax a la bash.
By default, history expansion is enabled with this plugin when using Term::ReadLine::Gnu. That means that "loose" '!' characters will be
treated as history events which may not be what you wish.
To avoid this, you need to quote the '!' with '':
my $var = "foo!";
or place the arguments in single quotes---but enable the "Term::ReadLine" attribute "history_quotes_inhibit_expansion":
$_REPL->term->Attribs->{history_quotes_inhibit_expansion} = 1;
my $var = 'foo!';
and to disable history expansion from GNU readline/history do
$_REPL->term->Attribs->{do_expand} = 0;
CONFLICTS
Note that Term::ReadLine::Perl does not support a history expansion method. In that case, you may wish to use the Devel::REPL History
plugin which provides similar functions. Work is underway to make use of either History or ReadLineHistory consistent for expansion with
either the Term::ReadLine::Gnu support or Term::ReadLine::Perl.
