[PATCH v3] virsh: Provide completer for some pool-X-as commands
Posted by Abhiram Tilak 3 months, 1 week ago
From: notpua <atp@tutamail.com>

Provides completers for auth-type and source-format commands for
virsh pool-create-as and pool-define-as commands. Use Empty completers
for options where completions are not required.

Related Issue: https://gitlab.com/libvirt/libvirt/-/issues/9
Signed-off-by: Abhiram Tilak <atp.exp@gmail.com>
---
Changes in v2:
  - Fix all formatting errors
  - Change some options using Empty completers, to use
    LocalPath completers.
  - Add completers for AdapterName and AdapterParent using information
    from node devices.
Changes in v3:
  - Call virshNodeDeviceNameComplete with modified flags instead of 
    duplicating the whole implementation.

This should be in a separate commit. It is a change that's semantically
different to the rest.

We don't use TABs. I believe 'meson test' would have reported this.

There's no need to copy internals of virshEnumComplete().

I get the idea, but this can hardly work, because
virshNodeDeviceNameCompleter() has virCheckFlags(0, NULL);

which means it exits early and returns NULL (i.e. virsh falls back to
file name completion - which is surely not something desired).
