.SH "VERSION"

.SH "DESCRIPTION"
.IX Header "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.
.PP
By default, history expansion is enabled with this plugin when
using Term::ReadLine::Gnu. That means that
\&\*(L"loose\*(R" '!' characters will be treated as history events which
may not be what you wish.
.PP
To avoid this, you need to quote the '!' with '\e':
.PP
.Vb 1
\&  my $var = "foo\e!";
.Ve
.PP
or place the arguments in single quotes\-\-\-but enable the
\&\f(CW\*(C`Term::ReadLine\*(C'\fR attribute \f(CW\*(C`history_quotes_inhibit_expansion\*(C'\fR:
.PP
.Vb 2
\&  $_REPL\->term\->Attribs\->{history_quotes_inhibit_expansion} = 1;
\&  my $var = \*(Aqfoo!\*(Aq;
.Ve
.PP
and to disable history expansion from \s-1GNU\s0 readline/history do
.PP
.Vb 1
\&  $_REPL\->term\->Attribs\->{do_expand} = 0;
.Ve
.SH "CONFLICTS"
.IX Header "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.
