System Menu does not wait for shell script to finish before rendering

[GastroGeek]

Problem:
I have a script that does a whole bunch of things and I need to see a long list of results in the menu item (say 8-10 items). However, it intermittently shows differing numbers of items on every mouse click.

Example code (Reproduce):

#!/bin/bash

echo "ITEM_001"
echo "ITEM_002"
echo "ITEM_003"
echo "ITEM_004"
echo "ITEM_005"
echo "ITEM_006"
echo "ITEM_007"
echo "ITEM_008"
echo "ITEM_009"

Steps
Set up a bog standard menu app. Add this for the script (bash) and run.

Once running, repeatedly click the menu. It shows any random number of items, depending on how much of the script is executed, before rendering.

System:
El Capitan, Mac Mini, Dual Monitors.

Thinking aloud:
I did once try 'hacking' the code (I don't do xcode/objc)... seems there needs to be a check for when the processes have finished. Or... is there a way it could perhaps show a spinning progress and only update once all data has been returned? I realise this may be a tricky one due to the way OSX works but it really would make this a killer app! (well, OK it already is a killer app but yeah).

Keep it up and thanks!

Whatever is causing this issue might be responsible for #53 as well...

This workaround has been working great for me so far:

# add at the end of your script
sleep 0.1

Obviously not ideal since it causes a slight delay when clicking, but it's short enough to not annoy me so far.

I've discovered what's causing this but haven't gotten around to fixing it. Soon!

Now fixed in master.
