Ruby Scripting Manual

Datavyu Ruby API v1.0

Introduction

The Datavyu scripting API provides a scriptable interface to Datavyu's database, allowing you to manipulate your data, print in any format you'd like, or check your data for errors. Described in this guide are the classes and methods available to you, along with examples. A script repository is available where many example scripts can be found.

The database is broken into three different conceptual pieces: Variables, Cells, and Arguments. Variables represent each column in the Datavyu spreadsheet, Cells represent the cells within each column, and Arguments represent the values each cell contains (including the standard values of onset, offset, and ordinal).
