Walter and I were talking this morning that there should be a
high barrier of entry for one-liners in Phobos. The "print"
function is technically a one-liner (i.e. writefln with the
appropriate format string). On the other hand, it may be
convivial enough to warrant inclusion, and saves us from
embarrassing things such as producing meaningless output when
numbers are printed together.
There's been a bit of churn in the PR comments regarding the
utility of "print", and discussion diverged into other
functions such as "dump" etc. Keeping it on topic: any strong
cons and pros regarding the function? I want to either merge or
close the PR and move on.
Thanks,
Andrei
To be honnest I think it would add more confusion than anything
for newcommers to have yet another printing function but the name
is good and it is like python so it's easier for many.
I dislike some points of the API though, I think changing eol is
more common than changing separator so I would rather have the
two switched. Maybe even removed, replaced by a single switch
"eol=true" as contrary to python we have more powerful formating
functions at hand and I think restricting the domain of each
function would prove better on the long run in order to keep
consistency.
Also as the unittest shows it is hard to test a function that can
only print to stdout which raises an orange flag in my mind:
please, consider adding a way to supplant stdout. The best would
be to make the unittest work: file.print(i, i*i*i); as it
clearly comes from an natural expectation.
