There is an argument to be made that this can already be achieved by adding an rm
instruction to the post_fetch_method
. So in a sense this proposal is more about a convenience addition.
from datadeps.jl.
Actually, now that I think about it the following isn't that bad and it works. Also, looking at the code for rm
it seems cross platform.
post_fetch_method = file -> (run(BinDeps.unpack_cmd(file,dirname(file), ".gz", ".tar")); rm(file))
I'll leave this issue open in case you have some opinion on this. otherwise feel free to close
from datadeps.jl.
I was thinking about something similar to this initially.
I think you are right and that this is something that should have.
The way I was initially thinking of doing it was by including a helper a function: rm_after(fn) = file -> (fn(file); rm(file))
.
Which is a specific case of your solution.
Related would be to allow post_fetch_method
to take a iterator of commands and then run all of them.
Which is what Flux does for it's callbacks.
Problem there is that we already allow it to take a iterator, because of handling recursive structures.
and that would be ambiguous.
Another would be to include a helper a function like doall(xs...)= file-> foreach(xs(file), xs)
Yet another option would be to include helper functions, like:
extract(file) = run(BinDeps.unpack_cmd(file,dirname(file), ".gz", ".tar"))
which would have a partner
extract_and_rm(file) = (extract(file); rm(file))
which I think would be useful.

Done>
via the inclusion of an unpack
method, that has an option to no delete the orginals.
