How can I tell what DEFs are generating certain parts of my skin/template output?
In Foswiki 1.1+, the TRACE mode of
adds HTML comments at the beginning and end of every
statement with the name of the DEF that was P'd. This can aid debugging skins/templates by giving you the name of the DEF which produced some output.
Warning: Do not enable Templates.pm
TRACE mode on a live production site
Enabling TRACE mode in
requires modification of that file. This feature should probably be made more accessible, however it is worth noting that enabling this feature will
break your site - it will produce invalid HTML (comments where there shouldn't be) and the output will look broken in the web browser.
So it is designed for annotating the raw HTML source.
- Establish a parallel (non-public/production) version of your site
lib/Foswiki/Templates.pm: Look for the line which reads
use constant TRACE => 0; and change it to read
use constant TRACE => 1; (near the top)
- If you are running persistent perl like
mod_perl: restart apache
- View the HTML output from the page of interest; there should be HTML comments annotating the output as described above.
