Subject: [PATCH] perf tool: Return all events as auto-completions after comma
Date: Fri, 22 Dec 2017 18:57:35 +0800 [thread overview]
Message-ID: <1513940255-16528-1-git-send-email-yao.jin@linux.intel.com> (raw)
It's a follow up patch for one previous patch "perf tool: Improve
bash command line auto-complete for multiple events with comma."
It fixes an issue that no events are displayed when <TAB> is
directly typed after comma.
With this patch, now the result is:
root@skl:/tmp# perf stat -e cpu-cycles,<TAB>
Display all 2389 possibilities? (y or n)
alarmtimer:alarmtimer_cancel
alarmtimer:alarmtimer_fired
alarmtimer:alarmtimer_start
alarmtimer:alarmtimer_suspend

One remaining issue is that the auto-completions doesn't work well
for the event with ':'. For example, clk:clk_enable.
Because ':' is set as WORDBREAK by default in bash. Need more work
for this case.
