I'm coming back to this again [1].
What I still remain looking for is a concise guide on how to do stream
(string) processing in D, in a (hopefully) as simple and elegant way as
possible? [2] Any tips?
(The InformIT article seemed rather technical, and more focused on
proposing new APIs than explaining how to actually do this in D, as
efficiently as possible)
Best Regards

[1] Thinking to re-implement in D, some bioinformatics python scripts
I've created for Rosalind course platform.
[2] I'm using generator functions in python, so I wanted to get the same
nice low memory usage, by using stream processing

Many thanks!
I'll check these links.

Hi,
I found these slides very interesting, on how python generator patterns
can be used to create re-usable code-parts that can be "piped" togegher
ad infinitum, to create e.g. parsing pipelines requiring minimal memory
(things a sysadmin working with huge files might need quite often):

It would be nice to do this kind of stuff in D though, to hopefully
gain
some performance, so I wonder, is there similar stuff in D, and
where to
find info about it?
Cheers,

D uses the range concept. Phobos ranges are based on the ideas presented
in this article:
http://www.informit.com/articles/printerfriendly.aspx?p=1407357
But some of the design and even the names of range types have changed
since that article has been written.
These and other Phobos modules make use of ranges:

P.S. I am in the process of translating my Turkish D book to English.
For
completeness, here are the two chapters about ranges:
