A More Complex Template
[% if order.items.size -%] <ul> [% for order.items -%] <li>[% item.quantity %] [% item.description %]</li> [% end -%] </ul> [% end -%] --EOF--look inside...
- No more SHOUTING!
- Same old chomping operators
itemis the default
- These are
Thus Spake Andy:
Here's a more complex example. Keywords are now in lower case and
FOREACH has become just
for. Otherwise things are pretty much the same.
Note the use of the
- chomping flags at the end of the tags to eat the
newlines following the tag. In TT3 we call these inline tags.
Before moving on, check out the HTML debugging for this template (click
on the 'look inside' link - there's a link for every example in this
presentation). In particular, look at the
Output tab. TT3's error
handling is much improved. In this case we get a runtime error indicating
some undefined data. You get the line number (and I mean the proper line
number, not the start of the tag which could be miles away as it is in
TT2), a description of the error, and an extract of the source code complete
with "^ here" marker. I punch myself in the face (figuratively speaking)
every time I get lost trying to debug a TT2 template. Never again! The
Tree tabs are also worth a look, and don't forget to
click on the boxes.
