Programmatic and Direct Manipulation, Together at Last Abstract We present the SKETCH-N-SKETCH editor for Scalable Vec- tor Graphics (SVG) that integrates programmatic and direct manipulation, two modes of interaction with complementary strengths. In SKETCH-N-SKETCH, the user writes a program to generate an output SVG canvas. Then the user may di- rectly manipulate the canvas while the system infers real- time updates to the program in order to match the changes to the output. To achieve this, we propose (i) a technique called trace-based program synthesis that takes program ex- ecution history into account in order to constrain the search space and (ii) heuristics for dealing with ambiguities. Based on our experience writing more than 40 examples and from the results of a study with 25 participants, we conclude that SKETCH-N-SKETCH provides a novel and effective work- flow between the boundaries of existing programmatic and direct manipulation systems.
