From: Chen Hanxiao <chenhanxiao@xxxxxxxxxxxxxx> If we need to exclude one parameter from another, we could use member 'exclude_option' to specify one. With this flag, we could archive what Eric comments on: https://www.redhat.com/archives/libvir-list/2013-October/msg00965.html 1. COMMAND <TAB> or COMMAND --<TAB> Auto complete will NOT show option that marked as VSH_OT_ALIAS 2. COMMAND --sh<TAB> Auto complete will show --shareable (this one was marked as VSH_OT_ALIAS) 3. COMMAND --mode XXX <TAB> or COMMAND --mode XXX --sh<TAB> Auto complete will NOT show --shareable (we set new member exclude_option for mode) 4. COMMAND --shareable --mo<TAB> Auto complete will NOT show --mode (we set new member exclude_option for mode) Signed-off-by: Chen Hanxiao <chenhanxiao@xxxxxxxxxxxxxx> --- tools/virsh.c | 8 ++++++++ tools/virsh.h | 1 + 2 files changed, 9 insertions(+) diff --git a/tools/virsh.c b/tools/virsh.c index bad78c9..93f525e 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -2686,6 +2686,7 @@ vshReadlineOptionsGenerator(const char *text, int state) static int list_index, len; static const vshCmdDef *cmd = NULL; const char *name; + const char *exclude_option; if (!state) { /* determine command name */ @@ -2712,6 +2713,7 @@ vshReadlineOptionsGenerator(const char *text, int state) while ((name = cmd->opts[list_index].name)) { const vshCmdOptDef *opt = &cmd->opts[list_index]; + exclude_option = opt->exclude_option; char *res; list_index++; @@ -2720,6 +2722,12 @@ vshReadlineOptionsGenerator(const char *text, int state) /* ignore non --option */ continue; + if (len == 2 && opt->type == VSH_OT_ALIAS) + continue; + + if (exclude_option && (strstr(rl_line_buffer, exclude_option))) + continue; + if (len > 2) { if (STRNEQLEN(name, text + 2, len - 2)) continue; diff --git a/tools/virsh.h b/tools/virsh.h index b843788..89b284f 100644 --- a/tools/virsh.h +++ b/tools/virsh.h @@ -173,6 +173,7 @@ struct _vshCmdOptDef { * the name of a later public option */ vshCompleter completer; /* option completer */ unsigned int completer_flags; /* option completer flags */ + const char *exclude_option; /* check the exclusion of option */ }; /* -- 1.8.2.1 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
