Filenames

[aloofschipperke]

The four-component filename from ITS provided many interesting features for DDT.

Device and sname can be mapped directly. Fn1 fn2 not so much.

One option is to not implement fn2 -- device:dir;fn

Opinions?

I haven't implemented ITS-type filename parsing, but I'm preparing for it.
The code uses system calls such as openat(), which use a directory file descriptor, This maps nicely to "sname;".

No use of "dev:" yet,

The latest update includes filename parsing.
dev: dir; filename
Various arrangements of this should work.
The only dev: is currently dsk:, which is /.
The directory portion is parsed, but not supported yet.

Some special filenames. Showing as two-name filenames, so not yet listing them in a checklist.

.file. (dir)
.m.f.d. (file)
..new. (dir) (typo here. correct one is ..new. (udir)
< as fn1 or fn2
> as fn1 or fn2

Are you sure the ..new. FN2 isn't (udir), rather than (dir)?

[aloofschipperke]

oof, yes.
Noting it above.
