Lack of error reporting in embperl 2 ?
This isn't so much a bug in embperl 2, as it is a lack of an expected error
message
I have the following script:
<html>
<head>
</head>
<body>
[-
$table_type=2;
-]
[$ if ($table_type == 1) $]
<table>
<tr><td>One kind of table</td></tr>
</table
[$ else $]
<table>
<tr><td>Another kind of table</td></tr>
</table>
[$ endif $]
</body>
</html>
NOTE the missing close angle bracket on the first </table> tag !
When this page is displayed, no error is thrown up and the output is all the
html except that which would have come out of the buggy if statement.
Thanks

EmbPerl does not validate html.
I once heard that the reason that Natscape was so bloated, was because
that it tries to render these things correctly. i.e. anticipate bad
html syntax.
you could use LWP (Lib-www) and a html validator found here www.w3.org
to procativaly test the output of your dynamic pages.

I know that the error reporting of Embperl has to be improved, but such an
error is hard to catch. The above code becomes one html tag:
</table [$else$] <table>
you can argue that the opening < inside the tag is wrong. That's right, of
course, but if I catch it, the next one who is using JavaScript will beaten
by this because now he can't use the less than sign....
I think one point would be to try to catch the bad nesting of if/else/endif
and table, I check this out and see what I can do...
