Currently the VSH_OT_ARGV options don't support complete, But some of VSH_OT_ARGV options are gonna support complete in upcoming patches. Once applied the upcoming completion patches for VSH_OT_ARGV options, If we don't ignore VSH_OT_ARGV here, The vshReadlineOptionsGenerator will be called, Hence complete output will consist of the result by command completer + the result by option completer, It's confusing. e.g. $ virsh domstats --domain <TAB><TAB> --backing --interface --list-paused --perf --vcpu --balloon leap42.3 --list-persistent --raw win10 --block --list-active --list-running sles12sp3 --cpu-total --list-inactive --list-shutoff sles15 --enforce --list-other --list-transient --state After this patch and the upcoming completion patches: $ virsh domstats --domain <TAB><TAB> leap42.3 sles12sp3 sles15 win10 Signed-off-by: Lin Ma <lma(a)suse.com&gt; --- tools/vsh.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/tools/vsh.c b/tools/vsh.c index 38058c874a..5a9916cbb0 100644 --- a/tools/vsh.c +++ b/tools/vsh.c @@ -2824,7 +2824,9 @@ vshReadlineParse(const char *text, int state) if (!cmd) { list = vshReadlineCommandGenerator(text); } else { - if (!opt || (opt->type != VSH_OT_DATA && opt->type != VSH_OT_STRING)) + if (!opt || (opt->type != VSH_OT_DATA && + opt->type != VSH_OT_STRING && + opt->type != VSH_OT_ARGV)) list = vshReadlineOptionsGenerator(text, cmd, partial); if (opt && opt->completer) { -- 2.15.1
