Javascript RegEx problem

[Mr.Clean]

I am working on modifying a syntax highlighter written in
javascript and it uses several regexes. I need to add a
language to the avail highlighters and need the following regexes
modified to parse the new language, Delphi/Pascal. Source to the
highlighter is avail here:

http://www.dreamprojections.com/SyntaxHighlighter/Default.aspx

*************** *************** *************** *
COMMENTS
*************** *************** *************** *
regex = new RegExp('//.*$|/\\*[^\\*]*(.)*?\\*/', 'gm');
Matches- single line comment: '// ' until end of line
multi line comment '{' until closing '}'
Example:

// This is a Comment

{
This is
a multiline comment
}

*************** *************** *************** *
STRINGS
*************** *************** *************** *
regex = new RegExp('"(?:\\. |[^\\""])*"', 'g');
Matches - any text enclosed in single quotes
if the string contains single quotes it will be
escaped like this:
'isn''t that grand'
Example:

'this is a string'

*************** *************** *************** *
DIRECTIVES/REGIONS
*************** *************** *************** *
regex = new RegExp('^\\s*{/$.*', 'gm');
Matches - '{' followed by '$' followed by 1+ Alpha chars
closed with '}'
Example:

{$IFDEF YAHOO} // this is a directive
{$ELSE YAHOO} // this is a directive
{$ENDDEF YAHOO} // this is a directive

{$R *.res} // this is a directive

*************** *************** *************** *
NUMBERS
*************** *************** *************** *
regex = new RegExp('/[^\d]/gi', 'g');
Matches - integer = numeric chars only
float = numerics and decimal only, no commas
hex = '$' foloewd by any combination of 'A'-'F'
and/or 0-9
Example:

x := x + 1234; // example of a number
y := y + 1.0; // example of a float number
z := $FFAA; // example of a hex number


for instance, in the first example:
regex = new RegExp('//.*$|/\\*[^\\*]*(.)*?\\*/', 'gm');
Matches - single line comment: '// ' until end of line
multi line comment '{' until closing '}'
Example:

// This is a Comment

{
This is
a multiline comment
}


the line:
regex = new RegExp('//.*$|/\\*[^\\*]*(.)*?\\*/', 'gm');

is the current regex.

the line(s):
- single line comment: '// ' until end of line
multi line comment '{' until closing '}'

spell out what I want the regex to match

and this:
Example:

// This is a Comment

{
This is
a multiline comment
}


Here is another one that I can't figure out.

Source:
asm
MOV AX,1234H
MOV Number,AX
end;

Need to match everything between the 'asm' and 'end;'

Needs also to support comment (* ... *).
One type of comment can contain the opening symbol for another.

Also (*$ ... *)

Also needs to handle such as 3.5e4 6.99E-07 .

Note that, to aid Continentals, (. and .) can be used for [ and ] -
there may be others similar that I have forgotten.

You know John, I forgot that you hangout here, too.
I am not even familiar with regex expressions. This is
a mod to allow a highlighter, noted below, to highlight Delphi
code.

The author was familiar with Delphi and got one working but
a few things were left out. The things you noted above and
asm blocks. I know that a parser will probably need to be
written to do the asm block kind of like how he did XML.

I know you know Delphi so would you be kind enough to help out?
