NAME
Sprog::Mixin::InputByLine - a 'mixin' class for gears reading input line-by-lineSYNOPSIS
use base qw( Sprog::Mixin::InputByLine Sprog::Gear );
DESCRIPTION
This mixin is for use by gears which use a 'pipe' style of input connector but want to process the input line-by-line. It defines a "data" method which passes each line of input to the gear's "line" method.METHODS
data ( buffer )
Extracts lines from the supplied buffer and passes them to the "line" method. A buffer which ends with some text that has no line terminator, will be handled as follows:- *
- if there are no more messages queued, the remaining text is re-queued until a subsequent message is received
- *
- if the next queued message is also a "data" message, the remaining text will be prepended to the next buffer
- *
- otherwise (if the next message is not a "data" message), the incomplete line will be passed to the gear's "line" method
A class that uses this mixin is expected to implement a "line" method.
