Topic: Basic syntax colouring with line numbers
Firstly, i realise there are a bunch of syntax colouring mods out there, but I like to make my own mods instead, i like to know exactly how things work and its good practice. You can see a demo, along with the instructions here: http://www.syi.cc/viewtopic.php?pid=521483#p521483
I am not properly releasing this mod yet, as it has afew things in it I would like to get sorted first.
- Escape characters are not handled properly within strings, for example in line 20 in the first code tag.
'/(\'.*\')/U'
This of course should be continuously coloured, as the whole thing is ment to be a string.
- If the line is too long, it pushes onto the next line, eg.
01.
$text .= '</p><div class="codebox"><div class="incqbox"><h4>'.$lang_common['Code'].':</h4><div>'."\n".parse_code($inside[$i])."\n".'</div></div></div><p>';
- Keywords are highlighted even if part of a word. Eg:
$newly
I assume in regex there must be an easy enough way to specify it must not be surounded by alphanumeric chars? Ill look into it later on, as I said, my regex isn't top.
- I would like to have the current line being hovered over highlighted. This is simple enough for FF, as you can use li:hover in css. However in IE :hover is only defined for a tags, with a href property. Is there some way around this?
Really I am posting this, hoping for some help fixing these problems, to be fair I haven't actually tackled either properly yet, but my regex knowledge isn't amazing (for the first one is there some way to say the ending tag must not be followed by a \?).
Any input is appreciated.
Thanks
