13 use STD;
14 use Syntax::Highlight::Perl6;
15 # Creates the Perl6 syntax highlighter object
17 my $p = Syntax::Highlight::Perl6->new(
18 text => 'my $foo;'
19 );
20 # Prints html that can be embedded in your pages
22 print $p->snippet_html;
23 # Prints html with css (useful for full pages)
25 print $p->simple_html;
26 # Prints html that has a JavaScript node viewer
28 print $p->full_html;
29 # Prints ANSI escaped color sequences (useful for console and IRC output)
31 print $p->ansi_text;
32 # Prints an array of token records (useful for other libraries)

37 "Syntax::Highlight::Perl6" parses Perl 6 source code using STD cpan
38 package. It matches parse tree nodes to colors then returns them in
39 different output formats. It can be used to create web pages with
40 colorful source code samples in its simple and snippet html modes, or
41 it can be used as a learning tool in examining STD.pm6's output using
42 the JavaScript node viewer in its full html mode. Or you can use its
43 parse tree Perl 5 records to build your next great idea.
44 The available output formats are:
46 · HTML (snippet,simple and full)
48 · ANSI escaped color sequences
50 · Perl 5 array of parse trees
52
54 This is an object-oriented module. The following methods are available:
55 new(options)
57 Returns the syntax highlighting object. It needs a hash of options.
58 The following options are available:
59 · text
61 This is a required option. This is where you should provide the
63 Perl 6 code.
64 · rule
66 parse rule name for STD.pm6 to parse against (default: TOP)
68 · inline_resources
70 Flag to enable/disable CSS/JavaScript HTML inlining. (default: 0
72 (Disabled))
73 · resource_url
75 HTML resource url that will be appended when resource inlining is
77 disabled.
78 · page_title
80 HTML page title for "simple_html" and "full_html" (default: q{})
82 · utf8_decode
84 Flag to enable/disable utf8 decoding. (default: 1 (Enabled))
86 · tmp_prefix
88 STD temporary files directory prefix. (default: q{})
90 snippet_html
92 Returns the Perl 6 highlighted HTML string that can be embedded. No
93 CSS or JavaScript is inside.
94 simple_html
96 Returns the Perl 6 highlighted HTML string. The HTML code is the same
97 as "full_html" but lacks a JavaScript Parse Tree Viewer.
98 full_html
100 Returns the Perl 6 highlighted HTML string. The HTML consists of a
101 JavaScript Parse Tree Viewer along with CSS-styling. It can inlined if
102 "inline_resources" option is 1.
103 ansi_text
105 Returns a Perl highlighted ANSI escape color string.
106 tokens
108 Returns an array of hashes containing parsed token records. The hash
109 record is structured as:
110 +-----------+---------+-----------+------------+---------+
112 | Matched | Matched | Matched | Parse tree | Matched |
113 | Last | string | rule | separated | Line |
114 | Position | buffer | name | by spaces | Number |
115 | | | | | |
116 | $last_pos | $buffer | $rule | $tree | $lineno |
117 +-----------+---------+-----------+------------+---------+
118 An example of the "tokens" method in action:
120 use Data::Dumper;
122 print Dumper($p->tokens);
123 The shortened output looks like:
125 $VAR1 = {
127 'tree' => '',
128 'rule' => 0,
129 'buffer' => '',
130 'last_pos' => 0
131 };
132 $VAR2 = {
133 'tree' => 'statementlist statement statement_modexpr statement_expr EXPR termish noun value number integer ',
134 'rule' => 'number',
135 'buffer' => '1',
136 'last_pos' => 1
137 };
138 $VAR3 = {
139 'tree' => 'statementlist eat_terminator ',
140 'rule' => 0,
141 'buffer' => ';',
142 'last_pos' => 2
143 };
144
146 This module is dependent on Perl 5.10 features namely the regex engine
147 and state variables (for STD.pm6). So there will be no Perl 5.8.x
148 support in the future.
149
151 Discussion about this module and STD.pm6 is usually in #perl6
152 (irc://irc.freenode.net/perl6). This module lives in
153 http://svn.perlide.org/padre/trunk/Syntax-Highlight-Perl6 . Larry
154 Wall's "STD.pm6" lives in http://github.com/perl6/std.

157 If you find any bugs, please submit them to
158 http://rt.cpan.org/NoAuth/Bugs.html?Dist=Syntax::Highlight::Perl6.
159 Thanks.
160 These are the bugs that i am currently aware of:
162 · Can't call method "bless" on an undefined value at STD.pm6 line
164 5269.
165 You have to put "use STD;" before using this module.
167 use STD; # this must be first for now
169 use Syntax::Highlight::Perl6;

172 The project idea was inspired by Moritz Lenz (moritz) -
173 http://www.nntp.perl.org/group/perl.perl6.users/2008/07/msg788.html .
174 Larry Wall's "gimme5"-generated Perl5 "STD.pmc" is included to parse
175 Perl 6 code. The initial STD tree traversal code was written by Paweł
176 Murias (pmurias). It was replaced afterwards for performance reasons
177 with Larry Wall's "redspans" traversal code. "redspans" stands for
178 "red" for reductions, and "spans" from the "from/to span calculations".
179 This library also includes the following libraries:
181 JQuery by John Resig (dual licensed under the MIT and GPL licenses).
183 Thanks guys. I could not have done it without you ;-)
