Just wanted to note that as of 2.8.0 (just released), you can now
embed Python code blocks in templates.
This makes it easy to enter the debugger from inside a template:
<?python import pdb; pdb.set_trace() ?>
<div tal:condition="...">
...
</div>
It works best if you're running in debug-mode since then the generated
source code is written out to disk, letting the debugger actually
"see" the code.
If you're an emacs user, consider binding this to M-p:
(fset 'pdb-pi-set "<?python import pdb; pdb.set_trace() ?>")
(global-set-key "\M-p" 'pdb-pi-set)
This extends on the common binding M-t:
(fset 'pdb-set "import pdb; pdb.set_trace()")
(global-set-key "\M-t" 'pdb-set)
Naturally, code blocks can be used for more than just debugging. I'm
not sure it's particularly useful. It allows you to write out a
Fibonacci-generator right from inside your templates – should you ever
need that.
Enjoy,
