Just as .name and .plugin_name can differ for filters, should we also
have a way to report independent version numbers (via .version) for the
filter, compared to the version of the underlying plugin (via
.plugin_version)?
As it currently stands it's not necessary because main.c does:
if (version) {
const char *v;
struct backend *b;
display_version ();
for_each_backend (b) {
printf ("%s", b->name (b));
if ((v = b->version (b)) != NULL)
printf (" %s", v);
printf ("\n");
}
exit (EXIT_SUCCESS);
}
with the output:
$ ./nbdkit --filter offset --filter delay file --version
nbdkit 1.1.26
offset 1.1.26
delay 1.1.26
file 1.1.26
