[libvirt] [PATCH v2 12/15] tools: Separate host related completers into a file

Mixing all completers in one file does not support maintainability. Separate those completers which relate to host (e.g. they complete various host aspects) into virsh-completer-host.c Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- tools/Makefile.am | 1 + tools/virsh-completer-host.c | 148 +++++++++++++++++++++++++++++++++++ tools/virsh-completer-host.h | 31 ++++++++ tools/virsh-completer.c | 121 ---------------------------- tools/virsh-completer.h | 9 +-- 5 files changed, 181 insertions(+), 129 deletions(-) create mode 100644 tools/virsh-completer-host.c create mode 100644 tools/virsh-completer-host.h diff --git a/tools/Makefile.am b/tools/Makefile.am index 3a89ec70a2..43083f4afa 100644 --- a/tools/Makefile.am +++ b/tools/Makefile.am @@ -219,6 +219,7 @@ virsh_SOURCES = \ virsh-checkpoint.c virsh-checkpoint.h \ virsh-completer.c virsh-completer.h \ virsh-completer-domain.c virsh-completer-domain.h \ + virsh-completer-host.c virsh-completer-host.h \ virsh-completer-interface.c virsh-completer-interface.h \ virsh-completer-network.c virsh-completer-network.h \ virsh-completer-nodedev.c virsh-completer-nodedev.h \ diff --git a/tools/virsh-completer-host.c b/tools/virsh-completer-host.c new file mode 100644 index 0000000000..7e31ca2bf3 --- /dev/null +++ b/tools/virsh-completer-host.c @@ -0,0 +1,148 @@ +/* + * virsh-completer-host.c: virsh completer callbacks related to host + * + * Copyright (C) 2019 Red Hat, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
