Creating an Agile Python Environment: Mac

This gist assumes you are on a Mac. It also assumes that you already have Python and pip installed and that you are most likely using Python version 2.7.x. If your environment differs you may have to work a little harder to get things sorted but hopefully the gist of the gist (agile Python) will still be useful for you. If you are on a windows machine, this is probably not the gist you are looking for.

We will take the minimum amount of steps nessessary to set up a complete set of tools that are fully controllable from the command line. Use your text editor or IDE of choice for creating the spec and implementation files. Note that some IDEs (i.e. PyCharm) make some of what we cover below a lot easier (i.e. debugging) but it is probably still useful to understand what is going on behind the scenes.

We will create a simple application that pulls down Guido van Rossum's twitter feed and prints out some of his latest perls of wisdo

Since an MGLAnnotationView is a UIView you can use familiar APIs to manipulate it. For example, on devices that support 3D touch, you can transform the view as a function of the touch force.

override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    super.touchesMoved(touches, withEvent: event)

    if let touch = touches.first {
        let normalizedForce = touch.force / touch.maximumPossibleForce * 2.5
        self.transform = CGAffineTransformMakeScale(1 + normalizedForce, 1 + normalizedForce)
    }

    MGLSource *source = [[MGLSource alloc] initWithSourceIdentifier:@"source"];
    MGLSymbolStyleLayer *symbolLayer = [[MGLSymbolStyleLayer alloc] initWithLayerIdentifier:@"place-city-sm" source:source];
    
    NSDictionary *options = @{MGLGeoJSONClusterOption: @(YES),
                              MGLGeoJSONClusterRadiusOption: @10,
                              MGLGeoJSONClusterMaximumZoomLevelOption: @15};
    
    MGLGeoJSONSource *geoJSONSource = [[MGLGeoJSONSource alloc] initWithSourceIdentifier:@"earthquakes" URL:url options:options];

- (void)mapViewDidFinishLoadingMap:(MGLMapView *)mapView
{
    [self.mapView setStyleURL:[MGLStyle darkStyleURLWithVersion:9]];
    
    NSURL *url = [[NSURL alloc] initWithString:@"mapbox://mapbox.mapbox-terrain-v2"];
    MGLVectorSource *vectorSource = [[MGLVectorSource alloc] initWithSourceIdentifier:@"terrain-data" URL:url];
    [self.mapView.style addSource:vectorSource];
    
    MGLBackgroundStyleLayer *backgroundLayer = [[MGLBackgroundStyleLayer alloc] initWithLayerIdentifier:@"background"];
