Re: String view of file

[Jesper Quorning <jesper.quorning@gmail.com>]

The original post was a bit of a mess, and I am not quite new to Ada. But I lack some skills regarding software construction and software engineering.

What I want goes something like this:
- Zero copy access to a (read-only) file.
- Get lines of file one by one as a stream of lines.
- Use a package instance as file representation.
- Stretch goal: Multiple implementations of File Instance (Standard, Fast, Compatible ..)

Refined version:
```Ada
package File
   is new File_Instance
    (Filename => "whatever",
      Implementation => Standard);
---
for Line of File.As_Line_Stream loop
   Parse (Line);
end loop;
```

I think Dewar has written something about string view of some data. I saw some tricky tricks in the GNAT.Snobol implementation. Links to papers anyone?

Sorry for the late follow-up.
