I use the phantastic Guard gem to do BDD in Rails. It's great that it executes all my specs etc. automatically after changing a file, but there are times where I don't want them to run immediately, and I pause Guard by pressing P in the console. But after several times, this becomes tedious, and it would be nicer to have a system wide keyboard shortcut or something to tell Guard to pause/unpause.
Anybody has an idea on how to accomplish this? Thanks.
I have an idea, but I'm unable to test if it works, since I enjoy my holiday and the data plan I quite expensive, so I try to limit my Internet usage.
You can execute a shell script like it's described under Fast User Switching/Apple Menu?. The script itself could send a signal to Guard to start/stop the listener.
Update:
The following script has been developed in Guard issue #303.
local FILE = "/tmp/.guardpaused"
if [ -f FILE ]; then
ps -ef | grep -i guard | grep -v grep | awk '{print $2}' | xargs kill -USR2
rm FILE
echo "Unpaused files modification listening."
else
ps -ef | grep -i guard | grep -v grep | awk '{print $2}' | xargs kill -USR1
touch FILE
echo "Paused files modification listening."
