The Flying Meat Wiki: AcornTurnOnShapeShadows

This example loops through the selected shapes in a shape layer, and turns on the shadows. If there are no selected shapes, then it loops through all the shapes in the layer.

Note: This plugin requires Acorn 1.0.3

@implementation TurnOnShadows

+ (id) plugin {
	return [[[self alloc] init] autorelease];
}

- (void) willRegister:(id<ACPluginManager>)pluginManager {
	
	[pluginManager addFilterMenuTitle:@"Turn on shadows"
	               withSuperMenuTitle:@"Shape"
	                           target:self
	                           action:@selector(turnOnShadows:userObject:)
	                    keyEquivalent:@""
	        keyEquivalentModifierMask:0
	                       userObject:nil];
}

- (void) didRegister {
	
}

- (void) turnOnShadows:(id<ACShapeLayer>)layer userObject:(id)uo {
	
	if ([layer layerType] != ACShapeLayer) {
	    return;
	}
	
	NSArray *graphics = [layer selectedGraphics];
	
	if (![graphics count]) {
	    graphics = [layer graphics];
	}
	
	[graphics makeObjectsPerformSelector:@selector(setHasShadow:) withObject:[NSNumber numberWithBool:YES]];
	
}


- (NSNumber*) worksOnShapeLayers:(id)userObject {
	return [NSNumber numberWithBool:YES];
}

@end

And the same plugin in Python:

import objc
from Foundation import *
from AppKit import *

ACScriptSuperMenuTitle = None
ACScriptMenuTitle = "Shape Layer test"
ACShortcutKey = 'k'
ACShortcutMask = "shift command"

ACBitmapLayer = 1
ACShapeLayer = 2

# this only works in Acorn 1.0.3+

def layerAction(currentLayer):
	
	if currentLayer.layerType() != 2:
	    return
	
	graphics = currentLayer.selectedGraphics()
	
	if len(graphics) == 0:
	    graphics = currentLayer.graphics()
	
	for graphic in graphics:
	    
	    graphic.setHasShadow_(True)
