Google App Engine Development Console from command line

When you develop on localhost the interactive console that Google provides is not convenient.
In my project I had to run few scripts in the console quite often, so instead of going to the interactive console all the time I could do it from command line.

This example executes the 'gen_pilot_data.py' script on the interactive console.

curl --data-urlencode "code=`cat src/gen_pilot_data.py`" http://localhost:8079/_ah/admin/interactive/execute

Please notice that you may have to the change the port number.

Zoom to fit all markers with Google Maps V3

// creating the map
var map = new google.maps.Map(document.getElementById("map_canvas"), {
  mapTypeId: google.maps.MapTypeId.ROADMAP
});

// latitude, longitude values
var latLons = [ { lat: 35.6453962, lon: 139.7117893 }, 
                           { lat: 35.645076, lon: 139.709183 }  ];

// this is the bounding box container
var bounds = new google.maps.LatLngBounds();

// iterating through the points
latLons.forEach( function (element, index, array) {

  var point = new google.maps.LatLng(element.lat,element.lon);
  
  // extending the bounding box
  bounds.extend(point);

  // creating the marker on the map
  var marker = new google.maps.Marker({
        position: point,
        map: map
    });
});

// zooming on the map
map.fitBounds(bounds);

Reload the browser with AppleScript

This post is obsoleted, here is the new simplified version.

AppleScript is a weird language but you still can do cool things with it.

tell application "Google Chrome"
        activate
end tell

tell application "System Events"
 tell process "Google Chrome"
  keystroke "r" using {command down}
 end tell
end tell

Please feel free to replace "Google Chrome" with your choice.
