3 | # A bash command completion script for ovs-appctl. | |
4 | # | |
5 | # | |
6 | # Right now, the script can do the following: | |
7 | # | |
8 | # - display available completion or complete on unfinished user input | |
9 | # (long option, subcommand, and argument). | |
10 | # | |
11 | # - once the subcommand (e.g. ofproto/trace) has been given, the | |
12 | # script will print the subcommand format. | |
13 | # | |
14 | # - the script can convert between keywords like 'bridge/port/interface/dp' | |
15 | # and the available record in ovsdb. | |
16 | # | |
17 | # The limitation are: | |
18 | # | |
19 | # - only support small set of important keywords | |
20 | # (dp, datapath, bridge, switch, port, interface, iface). | |
21 | # | |
22 | # - does not support parsing of nested option | |
23 | # (e.g. ovsdb-tool create [db [schema]]). | |
24 | # | |
25 | # - does not support expansion on repeatitive argument | |
26 | # (e.g. ovs-dpctl show [dp...]). | |
27 | # | |
28 | # - only support matching on long options, and only in the format | |
29 | # (--option [arg], i.e. should not use --option=[arg]). | |
30 | # | |
