Hi all,
I currently work on a parser for some file format. I wanted to use the
std.stdio.ByChunk Range to read from a file and extract tokens from the
chunks. Obviously it can happen that the current chunk ends before a
token can be extracted, in which case I can ask for the next chunk from
the Ra

I realize that I am using this compiler bug as a feature. It would be
kind of you to suggest me a code that would not exploit this bug. I

Ah.. Now I think I understand.

Thanks Steve for your inputs.
Actually this is part of a bigger code that I am trying to create.
Though I am pretty new to D.
What I have posted is a reduced code that illustrated the issue I

Hi,

Nice.
Maybe add support for predicated alternatives?
If you *really* want to make it more convenient, you could make a string
mixin front for it, so that one could do something like
mixin(maek_parser("
start -> s1 s2;
s1 -> (`ab`|`cd`) `ef`;
s2 -> (`1`|`2`|`3`);
"));

Hi,
I try to learn D and as a testproject I wanted to implement combinator
parsing for D.
That's what I currently have: https://gist.github.com/736456#file_parser.d
It is a simple combinator library including simple matchers,
alternatives, sequences, optional, transformations of the results
Hi,
does anyone know how I can cast a string to an enum which also
contains strings? For example:
enum MyENUM : string {
x = "123"
y = "456"
z = "789"
}
...
string myString = X;
to!(MyENUM)(myString); // Error: cannot implicitly convert
