I found myself doing this [+ local $escmode=0; $varName +] as well, and I
have realized that setting it globally can change it for the entire page.
Really, though, this is not a good solution for me, because I want to go
back and forth between escaped and unescaped blocks often within the page.
I am already using Embperl in an arrangement where I don't call it directly,
but rather call Embperl::Execute as a method of an object I have written.
This puts me in the fortunate situation of being able to pre-process my HTML
code a bit before it goes to Embperl. I have used the following regular
expression there and it has worked quite well: (the file contents is read
into $data, which is later passed to Execute through the input argument)
$data =~ s/\[\=(.*?)\=\]/[+ local \$escmode = 0; $1 +]/gs;
This translates any [= mysub() =] blocks to [+ local $escmode=0; mysub() +].
This is very convenient for switching back and forth between escaped and
unescaped blocks. The '=' has mnemonic value, too.
At the risk of what I would term "tag bloat", perhaps a new processing tag
along these lines could be added in a future Embperl release. I have to
imagine that it would be very convenient for many people.
