It looks very nice. I like the interactive shell in Python and
Haskell. Even languages like Scala enjoy it. The importance of a
good REPL can't be underestimated. I'd like a good repl in the
standard D distribution (despite the installation with dub is
easy).
Notes:
- Regarding the input and output lines, I suggest to take a look
at Mathematica and Sage. I think it's better to give numbers only
to the inputs (or separate numbers to inputs and outputs), and to
denote inputs and outputs differently. So there's no need for the
"=>".
- print stringNums: very nice.
- .map!(a => a.to!string) and .map!(a => S(a)) can also be
written like this:
import std.stdio, std.algorithm, std.range, std.conv;
void main() {
10.iota.map!text.writeln;
static struct S { int x; }
10.iota.map!S.writeln;
}
- is type x the same as print typeof(x) ?
- line 29: foreach that prints the last result of the iteration:
it's interesting.
I have followed the instructions:
git clone https://github.com/callumenator/dabble
cd dabble
dub build --config=console
But the compilation stops with the errors:
Running dmd (compile)...
...\dub\packages\pegged-master\pegged\dynamic\grammar.d(245):
Error: not a property eps
...\dub\packages\pegged-master\pegged\dynamic\grammar.d(418):
Error: not a property fail
I think DUB should print _where_ it copies files, and it should
use a less hard to find place to stores them. (An optional idea
is to store inside the directory of dub a link to the directory
where dub stores those files).
