PerlIO::via::EscStatus::Parser - parse out status escape lines
use PerlIO::via::EscStatus::Parser; my $ep = PerlIO::via::EscStatus::Parser->new; my ($text, $status) = $ep->parse ($input);
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.
$ep = PerlIO::via::EscStatus::Parser->new
Create and return a new parser object.
($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
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.
