NAME

Syntax::Highlight::RDF - syntax highlighting for various RDF-related formats

SYNOPSIS

use Syntax::Highlight::RDF;
my $syntax = "Syntax::Highlight::RDF"->highlighter("Turtle");
print $syntax->highlight($filehandle);

DESCRIPTION

Outputs pretty syntax-highlighted HTML for RDF-related formats. (Actually just adds <span> elements with class attributes. You're expected to bring your own CSS.)

Formats

• N-Triples

• N-Quads

• Turtle

• TriG

• Notation 3

• Pretdsl

• SPARQL Query 1.1 (but not property paths yet)

• SPARQL Update 1.1 (but not property paths yet)

• JSON - intended for RDF/JSON and SPARQL Results JSON, but just generic highlighting

• XML - intended for RDF/XML and SPARQL Results XML, but just generic highlighting

Methods

highlighter($format)

Factory method; generally preferred over calling new on a specific class.

"Syntax::Highlight::RDF"->highlighter("Turtle");
"Syntax::Highlight::RDF::Turtle"->new;  # avoid!

highlight($input, $base)

Highlight some RDF.

$input may be a file handle, filename or a scalar ref of text. (Most highlighters will also attempt to Do What You Mean if passed something else sane like an RDF::Trine::Model.) $base is an optional base for resolving relative URIs.

Returns a string of HTML.

tokenize($input)

This is mostly intended for subclassing Syntax::Highlight::RDF.

$input may be a file handle, filename or a scalar ref of text.

Returns an arrayref of token objects. The exact API for the token objects is subject to change, but currently they support TYPE and spelling methods.
