Template::LiquidX::Tag::Dump - Simple Perl Structure Dumping Tag (Functioning Custom Tag Example)
use Template::Liquid; use Template::LiquidX::Tag::Dump; print Template::Liquid->parse("{%dump var%}")->render(var => [qw[some sort of data here]]); # With Data::Dump installed: ["some", "sort", "of", "data", "here"]
This is a dead simple demonstration of extending Template::Liquid.
This tag attempts to use Data::Dump and Data::Dumper to create stringified versions of data structures...
use Template::Liquid; use Template::LiquidX::Tag::Dump; warn Template::Liquid->parse("{%dump env%}")->render(env => \%ENV);
...or the entire current scope with ....
.
use Template::Liquid; use Template::LiquidX::Tag::Dump; warn Template::Liquid->parse('{%dump .%}') ->render(env => \%ENV, inc => \@INC);
...or the entire stack of scopes with .*...
.*
use Template::Liquid; use Template::LiquidX::Tag::Dump; warn Template::Liquid->parse('{%for x in (1..1) %}{%dump .*%}{%endfor%}') ->render();
...becomes (w/ Data::Dump installed)...
do { my $a = [ [ { forloop => { first => 1, index => 1, index0 => 0, last => 1, length => 1, limit => 1, name => "x-(1..1)", offset => 0, rindex => 1, rindex0 => 0, sorted => undef, type => "ARRAY", }, x => 1, }, 'fix', ], ]; $a->[0][1] = $a->[0][0]; $a; }
Notice even the internal forloop variable is included in the dump.
forloop
This is a 5m hack and is subject to change ...I've included no error handling and it may be completly broken. For a better example, see Template::LiquidX::Tag::Include.
