Re: [RFC] arbitary maths evaluation
* Shevek shevek at anarres.org [2003-08-15 12:39]: The effective halfway house, which does produce a good but fast sandbox, is to parse the thing properly, generate a parse tree, then emit guaranteed clean Perl code from the parse tree, and eval that. This is how the Template Toolkit does it too, using a grammar generated using Parse::Yapp rather than Parse::RecDescent, with a custom parser. The nice thing about this approach is that you don't need Parse::* to run the code, which makes it more easily distributable.

You can reference previously matched RewriteCond stuff as %1, %2, %3,

Re: XML::Parser - using object methods as handlers
* Rhys Hopkins rhysh at aerotech-eu.net [2003-03-07 12:00]:
In my reference book (Perl XML by Ray McIntosh) it clearly states
that one can use object methods as handlers to avoid this global
variable scenario. However, the book and the XML::Parser manpage fail
to give specific examples as to how this is accomplished, and when I
try I encounter problems.
You can pass anonymous subroutines that contain references to your
object as the handlers. For example:
package My::XML::Thing;
...
sub parse {
my $self = shift;
my $parser = XML::Parser-new(Handlers = {
Start = sub { $self-parse_start_field(@_) },
Char = sub { $self-parse_char_field(@_) },
});
...
The handlers for Start and Char are closures, and contain a reference to
your object (in $self).

You could use Template::Parser directly:
