Template::Provider::EnUsernContributed Perl DocTemplate::Provider::Encoding(3)NAMETemplate::Provider::Encoding - Explicitly declare encodings of your
templates
SYNOPSIS
use Template::Provider::Encoding;
use Template::Stash::ForceUTF8;
use Template;
my $tt = Template->new(
LOAD_TEMPLATES => [ Template::Provider::Encoding->new ],
STASH => Template::Stash::ForceUTF8->new,
);
# Everything should be Unicode
# (but you can pass UTF-8 bytes as well, thanks to Template::Stash::ForceUTF8)
my $author = "\x{5bae}\x{5ddd}";
# this will emit Unicode flagged string to STDOUT. You might
# probably want to binmode(STDOUT, ":encoding($enccoding)")
# before process() call
$tt->process($template, { author => $author });
# in your templates
[% USE encoding 'utf-8' -%]
My name is [% author %]. { ... whatever UTF-8 bytes }
DESCRIPTIONTemplate::Provider::Encoding is a Template Provider subclass to decode
template using its declaration. You have to declare encoding of the
template in the head (1st line) of template using (fake) encoding TT
plugin. Otherwise the template is handled as utf-8.
[% USE encoding 'utf-8' %]
Here comes utf-8 strings with [% variable %].
DIFFERNCE WITH OTHER WAYS
UNICODE option and BOM
Recent TT allows "UNICODE" option to Template::Provider and by adding
it Provider scans BOM (byte-order mark) to detect UTF-8/UTF-16 encoded
template files. This module does basically the same thing in a
different way, but IMHO adding BOM to template files is a little
painful especially for non-programmers.
Template::Provider::Encode
Template::Provider::Encode provides a very similar way to detect
Template file encodings and output the template into various encodings.
This module doesn't touch output encoding of the template and instead
it emits valid Unicode flagged string. I think the output encoding
conversion should be done by other piece of code, especially in the
framework.
This module doesn't require you to specify encoding in the code, nor
doesn't guess encodings. Instead it forces you to put "[% USE encoding
'foo-bar' %]" in the top of template files, which is explicit and, I
think, is a good convention.
