A few of my colleagues and me are using Cloudapp a lot to share screenshots. Lately w were getting fed up with the nagscreens of Cloudapp to pay so i quickly assembled a homebrewn solution for use on our Macbooks.
What we want to do is implement the following workflow:
Whenever we use the default screen-capture functions of OSX (ex: cmd-shift-3 or cmd-shift-4), upload the resulting screenshot to imgur and put the link to the url in our pastebuffer.
How can we do that?
- Monitor ~/Desktop for new .png files because OSX dumps screenshots on your Desktop. Here we’re going to use FSWatch.
- Fswatch will call a little shellscript to upload to http://imgur.com and put the url in our pastebuffer with pbcopy.
1. The upload script
Put the following in ~/scripts/imgur.sh.
#!/bin/bash # # Upload image to imgur and put the url to the image in paste-buffer # # You need to register a CLIENT_ID at https://api.imgur.com/oauth2/addclient # CLIENT_ID="YOUR IMGURL CLIENT ID" API_BASE=https://api.imgur.com/3/image.xml IMAGE=$1 # echo "Incoming: $IMAGE" >> /tmp/imgurl.log if echo $IMAGE | grep -q "Screen Shot.*\.png$" ; then #echo "IS SS: $IMAGE" >> /tmp/imgurl.log IMGURL=`/curl -s -F "image=@$IMAGE" -H "Authorization: Client-ID $CLIENT_ID" $API_BASE | grep -E -o "<link>(.)*</link>" | grep -E -o "http://i.imgur.com/[^<]*"` # echo $IMGURL >> /tmp/imgurl.log echo $IMGURL | pbcopy /usr/local/bin/terminal-notifier -message "$IMGURL" -title "IMGUR Screenshot" fi
Make sure to make the file executable afterward:
chmod +x ~/scripts/imgur.sh
2. On El Capitan: Send notification
We also want a little notification when the upload is complete. For this we need Terminal Notifier.
brew install terminal-notifier
3. The filesystem watcher
brew install fswatch
Put the following in ~/scripts/imgurfswatch.sh:
fswatch -0 --event=Created --event=Renamed ~/Desktop/ |xargs -0 -n 1 ~/scripts/imgur.sh
This script needs to be executable:
chmod 755 ~/scripts/imgurfswatch.sh
4. Start it automatically on boot
We want to start up the watcher automatically when we boot. For this we use Launchd.
Insert the following in ~/Library/LaunchAgents/com.cjware.imgurl.plist
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.cjware.imgurl</string> <key>RunAtLoad</key> <true/> <key>StartInterval</key> <integer>15</integer> <key>KeepAlive</key> <true/> <key>Program</key> <string>/Users/<YOUR USER NAME HERE>/scripts/imgurfswatch.sh</string> <key>StandardOutPath</key> <string>/var/log/cjware_fswatch.log</string> <key>StandardErrorPath</key> <string>/var/log/cjware_fswatch.log</string> </dict> </plist>
Touch the log-file:
Make it execute on boot:
launchctl load -w ~/Library/LaunchAgents/com.cjware.imgurl.plist
