Literally code the same in another programming language. Suppose there
are going to be other programs working with the same data in similar ways.
extern(C) - you can now access it with C/C++, and D has bindings for a
good few scripting languages! Why rewrite your code in another language
at all? :D
As for patching for new input, that's a doddle if it's well written.
Changing a regex on the other hand... It's generally easier to write
it from scratch than decipher a current one.
I see, the deciphering could really get tricky. As for rewriting from
scratch that's something you generally try hard to avoid with
handwritten stuff.
You generally don't need to rewrite it when it's hand written, just
tweak it.
Of course, I don't feel that grants them a place in the language
though. Particularly with the likes of octal! - it can quite easily be
in a library and work just as well.
Sure thing it shouldn't be built it. D isn't awk.
Glad we agree!
I have, and I use regex for it. Those kinda things just need a quick
hack, and that's how I treat regex. If I'm doing anything that's
getting used in production code/anything that isn't intended to be a
hack I write a proper parser.
Ok, so I think we can agree on the simple fact that there are things
that just do not worth handwritten parser.
Of course.
