I'll add this to my todo list.
After some dig, the only problem I don't know how to solve is commands with variable-length parameters, such as copy-in. Its synopsis is: copy-in local [local ...] /remotedir At first think its style could be: "style = RErr, [StringList "local"], []; But it seems the syntax corresponding to StringList is: copy-in "local local" /remotedir e.g. its a one parameter of List type, but not several parameters. Any ideas? Regards, Hu _______________________________________________ Libguestfs mailing list [email protected] https://www.redhat.com/mailman/listinfo/libguestfs
