Hi
Perl allows to open an file "abstraction" ° by providing a scalar-ref to a string
open FH, "<", \$str;
which is cool, because we can reuse all functionality based on reading files. Like with cached files.
see open#Opening-a-filehandle-into-an-in-memory-scalar for details.
But is there a way to do it with opendir ,too?
I did some experiments providing a scalarref, but with no avail.
like opendir DH, \$str
Since telldir returns an integer-positions, I suppose the input has to be a scalar text with line delimiters and not an array.
Motivation
- primary: this question "glob an array?" would be trivial if we could chdir DH to a directory-handle which abstracts an array and glob it
- secondary: Powershell has some cool features based on directory abstraction of recursive structures, like cd registry-key and navigating it like a filesystem.
DISCLAIMER: Since I'm not very optimistic about an existing solution, this should probably rather be a meditation (?)
°) dunno how to phrase it better
