NAME

PerlIO::via::EscStatus::Parser - parse out status escape lines

SYNOPSIS

 use PerlIO::via::EscStatus::Parser;
 my $ep = PerlIO::via::EscStatus::Parser->new;
 my ($text, $status) = $ep->parse ($input);

DESCRIPTION

An EscStatus::Parser object parses out EscStatus format status strings from text. This is used by the EscStatus layers and is offered for parsing a stream the same way the layers do.

FUNCTIONS

$ep = PerlIO::via::EscStatus::Parser->new

Create and return a new parser object.

($text, $status) = $ep->parse ($input)

Parse an input string $input and return the plain $text part of that input, and the last complete $status line. If there's no complete status line yet then $status is undef. If there's no plain text, ie. if the input is entirely status, then $text is an empty string "".

$input doesn't have to be complete lines. Any partial status at the end of it is held in $ep and will be returned on a later parse call when the full line has been received.
