13 | # $cmddef defines which (sub)commands are available in a specific CLI class. |
14 | # A real command is always an array consisting of its class, name, array of | |
15 | # position fixed (required) parameters and hash of predefined parameters when | |
16 | # mapping a CLI command t o an API call. Optionally an output method can be | |
17 | # passed at the end, e.g., for formatting or transformation purpose. | |
18 | # | |
19 | # [class, name, fixed_params, API_pre-set params, output_sub ] | |
20 | # | |
21 | # In case of so called 'simple commands', the $cmddef can be also just an | |
22 | # array. | |
23 | # | |
24 | # Examples: | |
25 | # $cmddef = { | |
26 | # command => [ 'PVE::API2::Class', 'command', [ 'arg1', 'arg2' ], { node => $nodename } ], | |
27 | # do => { | |
28 | # this => [ 'PVE::API2::OtherClass', 'method', [ 'arg1' ], undef, sub { | |
29 | # my ($res) = @_; | |
30 | # print "$res\n"; | |
31 | # }], | |
32 | # that => [ 'PVE::API2::OtherClass', 'subroutine' [] ], | |
33 | # }, | |
34 | # dothat => { alias => 'do that' }, | |
35 | # } | |
