Indiscripts

Suppose you have an ExtendScript class (I mean, “prototype”) whose methods essentially return new object instances. As an obvious example, consider the concat or slice methods of Array.prototype. They always produce a new array rather than reworking the existing one. There are situations where you want to update the calling object —and make this explicit in the code— while still leveraging the methods already available…

If you are one of the happy users of the IdExtenso scripting framework for InDesign, you may have noticed — or overlooked! — that this enhanced version of ExtendScript provides many additional services, including in the primitive areas of the language. For example, any string immediately has functionalities like trim(), codePointAt(), toUTF8(), which aren't available in the root syntax. Let's take a closer look at this toolbox…

Geometry in InDesign can get deadly complex. Take a document, create a frame, insert a table, change a particular cell into a “graphic cell,” convert its inner object into an ellipse, play with strokes, rotate and scale the object, transform the parent frame in the fanciest way. Then ask yourself the question: what are the exact coordinates, shape or area of the final table cell?…

In most cases, ExtendScript regular expressions cannot digest the (a|b)+ scheme. This bug is not new, but it's worth defining its symptoms and extent. This article presents a very simple problem, with no known solution to date…

Coordinate Spaces & Transformations is a free eBook covering all atomic subjects that a InDesign scripter or developer should grab before using transformation matrices and the related methods. The last update has minor corrections and notes…

In this episode, you will learn how to arrange your code so that it fits into IdExtenso's “modular space.” Modularity is a key term when it comes to maintaining a large-scale project. Even if our sample script is not in itself of pharaonic complexity, we will transform it, as an exercise, into a pure module…

So, you have the root idea and a basic code for your next InDesign script. All is fine. It works so well that you're now planning to release it, which opens additional questions: Will it work everywhere? How do I trace risky functions? What if I need to integrate new features later on? How do I deal with persistent user settings? How to add a basic interface? How will I localize the dialog in other languages? Can I make my script available in a dedicated menu? Will it work in a JSXBIN package as well? Can I obfuscate my code?…
