7:53:11 vasily I wonder if it's a tool to make documentation for third-party software too.

8:02:02 vasily Is there any way to read vectors of arbitrary (more or less) numeric element type from (unsigned-byte 8) streams without using slow tools like nibbles? I don't really know C++, but I think I want something like std::as_bytes or std::as_writable_bytes. In ANSI CL you cannot displace an array into other array of different type, but maybe SBCL has something for this?

8:10:36 vasily Use case: suppose you have a stream which contains both single-float's, double-float's etc. You don't want to reopen it any time you want to read a value of different type. Nibbles reads or writes vectors just using a loop.

8:21:48 Shinmera Imagine being so confidently wrong

8:38:46 hayley Shinmera: Well, we don't need to imagine. Clearly vasily uses arm64 and my VOPs for that haven't been upstreamed yet :)

10:39:54 vasily VOP or not VOPs it tooks 25 seconds to load 100MB file

10:44:31 vasily Do I need a more fresh version or something?

14:10:50 stassats` read into an ub8 array and then access it according to your needs. if you really need to create arrays from it, then you won't have any luck with nibbles
