SYNOPSIS

        use Syntax::Highlight::Engine::Simple;
        
        # Constractor
        $highlight = Syntax::Highlight::Engine::Simple->new(%hash);
        
        # Parameter configuration
        $highlight->setParams(%hash);
        
        # Syntax definision and addition
        $highlight->setSyntax(%hash);
        $highlight->appendSyntax(%hash);
        
        # Perse
        $highlight->doFile(%hash);
        $highlight->doStr(%hash);
        
        # Utilities
        $highlight->array2regexp(%hash);
        $highlight->getClassNames(%hash);

DESCRIPTION

This is a Syntax highlight Engine.

Advantages are as follows.

Simple

Provides you a simple interface for syntax definition by depending on regular expression.

Fast

This works much Faster than Text::VimColor or Syntax::Highlight::Engine::Kate.

Pure Perl

Here is a working example of This module.

INTERFACE

new

type

File type. This argument causes specific sub class to be loaded.

syntax

With this argument, you can assign rules in constractor.

setParams

html_escape_code_ref

HTML escape code ref. Default subroutine escapes 3 charactors '&', '<' and '>'.

setSyntax

Set the rules for highlight. It calles for a argument syntax in array.

        $highlighter->setSyntax(
            syntax => [
                {
                    class => 'quote',
                    regexp => q@'.*?(?<!¥¥¥¥)'@,
                    allowed_container => ['tag'],
                },
                {
                    class => 'wquote',
                    regexp => q@".*?(?<!¥¥¥¥)"@,
                    allowed_container => ['tag'],
                },
            ]
        );

The array can contain rules in hash which is consists of 3 keys, class, regexp and allowed_container.

class

This appears to the output SPAN tag.

regexp

Regular expression to be highlighted.

allowed_container

An array of class name. This restricts the regexp to stand only in the classes. This param also works to ease the regulation some time. The highlighting rules doesn't stand in any container in default. allowed_container eliminate it to be a daughter of them.

appendSyntax

Append syntax by giving a hash.

        $highlighter->setSyntax(
            syntax => {
                class => 'quote',
                regexp => q@'.*?(?<!¥¥¥¥)'@,
                allowed_container => ['tag'],
            }
        );

doStr

Highlighting strings.

        $highlighter->doStr(
            str => $str,
            tab_width => 4
        );

str

String.

tab_width

Tab width for tab-space conversion. -1 for disable it. -1 is the defult.

doFile

Highlighting files.

        $highlighter->doStr(
            str => $str,
            tab_width => 4,
            encode => 'utf8'
        );

file

File name.

tab_width

Tab width for tab-space conversion. -1 for disable it. -1 is the defult.

encode

Set the encode of file. utf8 is the default.

array2regexp

This is a utility method for converting string array to regular expression.

getClassNames

Returns the class names in array.

DIAGNOSTICS

doStr method got undefined value

File open failed

CONFIGURATION AND ENVIRONMENT

Syntax::Highlight::Engine::Simple requires no configuration files or environment variables. Specific language syntax can be defined with sub classes and loaded in constractor if you give it the type argument.

DEPENDENCIES

UNIVERSAL::require

INCOMPATIBILITIES

None reported.
