Dear Niki,
To be specific, I am modifying negdivconf.mako which is with some
header like "pyfr:kernel". I create some constants in ini file
[constants] and quote em with ${['variable']}. However, it said
"TypeError: 'Undefined' object is not subscriptable". The total error
is shown below,
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/pyfr/util.py", line 33,

res = cache[key]

During handling of the above exception, another exception occurred:
