perlio::via::dynamic
dynamic(3) User Contributed Perl Documentation dynamic(3)NAME
PerlIO::via::dynamic - dynamic PerlIO layers
SYNOPSIS
open $fh, $fname;
$p = PerlIO::via::dynamic->new
(translate =>
sub { $_[1] =~ s/$Filename[:ws-./\]*$/$Filename: $fname$/e},
untranslate =>
sub { $_[1] =~ s/$Filename[:ws-./\]*$/$Filename$/});
$p->via ($fh);
binmode $fh, $p->via; # deprecated
DESCRIPTION
"PerlIO::via::dynamic" is used for creating dynamic PerlIO layers. It is useful when the behavior or the layer depends on variables. You
should not use this module as via layer directly (ie :via(dynamic)).
Use the constructor to create new layers, with two arguments: translate and untranslate. Then use "$p-"via ($fh)> to wrap the handle. Once
<$fh> is destroyed, the temporary namespace for the IO layer will be removed.
Note that PerlIO::via::dynamic uses the scalar fields to reference to the object representing the dynamic namespace.
OPTIONS
translate
A function that translate buffer upon write.
untranslate
A function that translate buffer upon read.
use_read
Use "READ" instead of "FILL" for the layer. Useful when caller expect exact amount of data from read, and the "untranslate" function
might return different length.
By default "PerlIO::via::dynamic" creates line-based layer to make "translate" implementation easier.
