Hello everybody,
I love Gretl's "foreign" code blocks capability, and would love even
more the possibility of using Python in them, which was at some time
suggested as easy to implement.¹
1) Has there been any development in this direction? If not, was it
because of lack of time/interest or because of unexpected obstacles in
the process?
Lack of manpower, I would say. I'm not overly familiar with python,
but it certainly is a language worth supporting.
2) In general, could it be feasible to apply structural changes on
gretl's dataset (i.e. remove/collapse observations) from foreign blocks?
Or will "append" remain the only reasonable channel of communication
from foreign blocks to gretl?
No, there's no way to modify the current dataset from a foreign block.
However, you could use the foreign block to write the data you need to
temporary files (as .mat files for matrices, presumably csv files for a
whole dataset) and then, after "end foreign", do a "dataset clear"
plus
open/join/append/mread()/whatever you need.
