It would really help out if we had some sort of semi-automated script
that can do at least partial translation of code that uses old phobos
functions to new ones. Maybe this wouldn't work 100% but at least it
would help out. I'm thinking of something similar to what Python 2to3
does.
I know for sure I could use this, so far I've had to fix the
DWinSamples for every DMD/Phobos release.
It would help to have a lexical analyzer of the kind that allows for the
refactorings in for example Eclipse for Java. Without clear identification
of symbols it is impossible to write such a script for every new D
release. And there were other changes in the past where this would have
been handy although I have not writing any D code lately to feel the
breakage. I think of globals (__gshared).
I'm on the extreme with my urge to rewrite things if they give me the
slightest feeling that they could be more elegant or effective and I've
thought of such a script as well that could be distributed with every new
D version while there are still breaking changes to the language. Well,
you cannot write a script without a solid foundation that can reliably
identify and refactor symbols.
But this doesn't work well for code you copy from blogs. You would have to
know what D version it was written with and run the matching chain of
conversion scripts. Anyway this feels like some crazy idea that can't make
it into existence.
Still I have that picture of downloading a new D release and running the
obligatory dmdup script to replace deprecated functionality or names with
the new versions. Sure at some point 'this is it' and features of D and
Phobos become set in stone. "Hello world!" console output is one of those
examples that many will try first. I would understand if it breaks between
major versions of a language, but not from one revision to the next. YMMV
:)
