WP-Syntax Other Notes

蚂蚱也是肉

点滴汇聚,终成大海

WP-Syntax provides clean syntax highlighting using GeSHi — supporting a wide range of popular languages. It supports highlighting with or without line numbers and maintains formatting while copying snippets of code from the browser.

It avoids conflicts with other 3rd party plugins by running an early pre-filter and a late post-filter that substitutes and pulls the code snippets out first and then pushes them back in with highlighting at the end. The result is source code formatted and highlighted the way you intended.

Usage

Wrap code blocks with <pre lang="LANGUAGE" line="1"> and </pre> where“LANGUAGE” is a GeSHi supported language syntax. See below for a full list of supported languages. The line attribute is optional.

The following languages are most supported in the lang attribute:

abap, actionscript, actionscript3, ada, apache, applescript, apt_sources, asm, asp, autoit, avisynth, bash, bf, bibtex, blitzbasic, bnf, boo, c, c_mac, caddcl, cadlisp, cil, cfdg, cfm, cmake, cobol, cpp-qt, cpp, csharp, css, d, dcs, delphi, diff, div, dos, dot, eiffel, email, erlang, fo, fortran, freebasic, genero, gettext, glsl, gml, bnuplot, groovy, haskell, hq9plus, html4strict, idl, ini, inno, intercal, io, java, java5, javascript, kixtart, klonec, klonecpp, latex, lisp, locobasic, lolcode lotusformulas, lotusscript, lscript, lsl2, lua, m68k, make, matlab, mirc, modula3, mpasm, mxml, mysql, nsis, oberon2, objc, ocaml-brief, ocaml, oobas, oracle11, oracle8, pascal, per, pic16, pixelbender, perl, php-brief, php, plsql, povray, powershell, progress, prolog, properties, providex,python, qbasic, rails, rebol, reg, robots, ruby, sas, scala, scheme, scilab, sdlbasic, smalltalk, smarty, sql, tcl, teraterm, text, thinbasic, tsql, typoscript, vb, vbnet, verilog, vhdl, vim, visualfoxpro, visualprolog, whitespace, whois, winbatch, xml, xorg_conf, xpp, z80

(Bold languages just highlight the more popular ones.)

Example 1: PHP, no line numbers

<pre lang="php"> <div id="foo"> <?php function foo() { echo "Hello World!\\n"; } ?> </div> </pre>

<pre lang="php">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre>

<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>

<?php

function foo() {

echo "Hello World!\\n";

}

</div>

Example 2: Java, with line numbers

<pre lang="java" line="1"> public class Hello { public static void main(String[] args) { System.out.println("Hello World!"); } } </pre>

1

<pre lang="java" line="1">
public class Hello {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}
</pre>

public class Hello {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}

public class Hello {

public static void main(String[] args) {

System.out.println("Hello World!");

}

Example 3: Ruby, with line numbers starting at 18

<pre lang="ruby" line="18"> class Example def example(arg1) return "Hello: " + arg1.to_s end end </pre>

<pre lang="ruby" line="18">
class Example
  def example(arg1)
    return "Hello: " + arg1.to_s
  end
end
</pre>

class Example
  def example(arg1)
    return "Hello: " + arg1.to_s
  end
end

class Example

def example(arg1)

return "Hello: " + arg1.to_s

end

Example 4: If your code already has html entities escaped, use escaped="true" as an option

<pre lang="xml" escaped="true"> &lt;xml&gt;Hello&lt;/xml&gt; </pre>

1

4

<pre lang="xml" escaped="true">
&lt;xml&gt;Hello&lt;/xml&gt;
</pre>

&lt;xml&gt;Hello&lt;/xml&gt;

1	<xml>Hello</xml>

Example 5: PHP, with line numbers and highlighting a specific line

<pre lang="php" line="1" highlight="3"> <div id="foo"> <?php function foo() { echo "Hello World!\\n"; } ?> </div> </pre>

<pre lang="php" line="1" highlight="3">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre>

<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>

<?php

function foo() {

echo "Hello World!\\n";

}

</div>

Example 6: PHP, with a caption (file and/or file path of the source file)

<pre lang="php" src"https://github.com/shazahm1/Connections/blob/master/connections.php"> <div id="foo"> <?php function foo() { echo "Hello World!\\n"; } ?> </div> </pre>

<pre lang="php" src"https://github.com/shazahm1/Connections/blob/master/connections.php">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre>

Styling Guidelines

WP-Syntax colors code using the default GeSHi colors. It also uses inline styling to make sure that code highlights still work in RSS feeds. It uses a default wp-syntax.cssstylesheet for basic layout. To customize your styling, copy the default wp-content/plugins/wp-syntax/wp-syntax.css to your theme’s template directory and modify it. If a file named wp-syntax.css exists in your theme’s template directory, this stylesheet is used instead of the default. This allows theme authors to add their own customizations as they see fit.

Advanced Customization

WP-Syntax supports a wp_syntax_init_geshi action hook to customize GeSHi initialization settings. Blog owners can handle the hook in a hand-made plugin or somewhere else like this:

&lt;?php
add_action('wp_syntax_init_geshi', 'my_custom_geshi_styles');

function my_custom_geshi_styles(&amp;$geshi)
{
    $geshi-&gt;set_brackets_style('color: #000;');
    $geshi-&gt;set_keyword_group_style(1, 'color: #22f;');
}
?&gt;

<?php

add_action('wp_syntax_init_geshi', 'my_custom_geshi_styles');

function my_custom_geshi_styles(&$geshi)

{

$geshi->set_brackets_style('color: #000;');

$geshi->set_keyword_group_style(1, 'color: #22f;');

}

This allows for a great possibility of different customizations. Be sure to review the
