Just one thing. I've been using php (www.php.net, similar to ASP or
SHTML, but cooler) to make my pages prettier and, unfortunately, it also
uses $ for variables. The RC parser in MHonArc blows up when I try to
include PHP code fragments that include variables as HTML fragments in my
rc file. For example, I have a little thing called a "theme" that shows
up on my web pages, and something like this:
<?
include "kylethemes.inc";
$theme = StartPage("Kyle",$HTTP_GET_VARS["theme"]);
?>
is at the top of all my pages. Your regex for searching for variables
($VarExp = '\$([^\$]*)\$'; in mhinit.pl) produces an error on this line
when it's used somewhere like IdxPgBegin. Changing it to this
\$([^\$\s]*)\$
Solves the problem, and shouldn't break any existing rc files since they
should be using variables/resources without spaces anyhow. Just a
thought.
The regex will break an addition I put into the next release and
potential break the use of user defined variables if a user used
a space in a custom variable name.
A solution is to escape the '$' so MHonArc will not think it is the
start of a resource variable. This is done by doing "$$". Taking
the example you provided, it can be redone as follows:
<?
include "kylethemes.inc";
$$theme = StartPage("Kyle",$$HTTP_GET_VARS["theme"]);
?>
