[Bash-completion-devel] Bug#685569: ifup/ifdown: support /etc/network/interfaces with ifscheme definitions

[Christoph Anton Mitterer]

Package: bash-completion
Version: 1:2.0-1
Severity: wishlist

Hi.

ifscheme is a program that allows several configuration sets to be
stored in /etc/network/interfaces for _one_ interface.

One get's then definitions like:
iface eth0-home inet static
	...
iface eth0-work inet dhcp
	...


For a given interface this is "configured" via
mapping eth0
	script ifscheme-mapping
in /etc/network/interfaces.


Now, currently, when I use completion on ifscheme managed interfaces I get:
# ifup e
[TAB]
th0-
i.e. it completes to the full names (eth0-home or eth0-work).

This is however useless, as ifup/ifudown itself cannot cope with these names;
it only supports interface names (e.g. eth0).

The current schema is always selected via the ifschem program.
E.g. a typical invocation looks like this:
# ifscheme work
# ifup eth0


Now, what I'd like to see is, that the completion code for ifup/ifdown detects
if a interface is handled by ifscheme (can be done via the mapping stanca) and
if so, it should only complete to the first "-".


Cheers,
Chris.
