Apparently[0] Nix 1.12 has a new ‘nix’ UI or wrapper with direct support
for listing NAR contents.
It[1] seems to work on modern-day (decompressed) Guix NARs too:
$ curl https://mirror.hydra.gnu.org/guix/nar\
> /gzip/5nhqwkvy7v51jd8lf4krljfbl01v6rx3-e2fsprogs-1.43.6 > my.nar.gz
$ gunzip my.nar.gz
$ /nix/store/*/bin/nix ls-nar -lR my.nar /
dr-xr-xr-x 0 ./bin
-r-xr-xr-x 18216 ./bin/chattr
-r-xr-xr-x 1540 ./bin/compile_et
-r-xr-xr-x 13888 ./bin/lsattr
-r-xr-xr-x 1356 ./bin/mk_cmds
dr-xr-xr-x 0 ./etc
-r--r--r-- 808 ./etc/mke2fs.conf
dr-xr-xr-x 0 ./include
lrwxrwxrwx 0 ./include/com_err.h -> et/com_err.h
dr-xr-xr-x 0 ./include/e2p
[...]
I haven't tried more than the above commands, nor do I use Nix anymore,
nor do I have any idea how good or reusable the code is, but it's a start.
Kind regards,
