Hey Dean,
what you've done with this plugin is absolutely fantastic. I'm using WordPress for the first time and I found your plugin very useful . But I want to be a bit more flexible with the line numbers, because sometimes I want to start them at another value than "1". So I've reviewed and enhanced your code a little bit to get this running for me. Since geshi can be initiated with a different line number than "1" I changed following lines in your code:
replaced (in function ch_the_content_filter)
return preg_replace_callback("/<pre\s+.*lang\s*=\"(.*)\">(.*)<\/pre>/siU",
array(&$this, "ch_highlight_code"),
$content);
with
return preg_replace_callback("/<pre\s+.*lang\s*=\"(.*)\"(\s+.*start\s*=\"(.*)\")?>(.*)<\/pre>/siU",
array(&$this, "ch_highlight_code"),
$content);
added in function ch_highlight_code
// start line_number
$start_line_number = $matches[3];
if (!is_numeric($start_line_number)) {
$start_line_number = 1;
}
directly after the global $ch_options; line
and
$geshi->start_line_numbers_at($start_line_number);
after
$geshi = new GeSHi($plancode, strtolower($matches[1]));
and changed $plancode = $matches[2]; to $plancode = $matches[4];
Now I can write the following in the WordPress editor:
<pre lang="php" start="123"><?php
echo "Hello World!\n";
?>
and the first line number will be 123.
cheers!
