How to Augment and Process Nested Groups (CS4-CS6)

Dealing with groups is a major headache for InDesign scripters. On one hand, the Group object has no injection method to offer, which makes difficult to append existing page items into a given group. On the other hand, although the Groups API exposes a promising add() method, nobody has ever managed to use this feature from any PageItem.groups area, so we seem doomed to perpetually rebuild groups from scratch.

So What's New in InDesign CS6 Scripting DOM

InDesign CS6 is full of new features, which explains the size (98 pages) of the Object Members part in our tracking-change PDF below. Of course many additions regard interactivity, form behaviors and the related events. The Scripting DOM now includes the following ubiquitous collections: checkBoxes, comboBoxes, listBoxes, radioButtons, signatureFields, textBoxes. A number of existing objects have been extended accordingly.

Besides, there are many interesting additions to discover and experiment. Have fun!

InDesign Scripting Forum Roundup #2

As opened in the “InDesign Scripting Forum: 25 ‘sticky’ posts” article, I will regularly feed this section with recommended discussions and/or snippets which I have contributed to through the ID Scripting Forum. Here is the scripting stuff I found specially interesting over the last six months…

Notes on ‘fastEntireScript’ Undo Mode

In April 2009, Thomas Silkjær reported a bug on app.doScript that alters the ‘undo’ feature in InDesign. Although this issue has been fixed in CS5, there are still some pitfalls to beware of when you want to speed up your script through fastEntireScript

Comparing the Performance of ExtendScript Snippets

Although jsPerf is a very effective tool in a pure JavaScript environment, you may want to benchmark competing code snippets in the specific ExtendScript field. Here is a simple way to test and improve your InDesign scripted functions…

Permutation d'objets dans InDesign (miniscript)

Non sans témérité, Stéphane Baril et David Deraedt nous ont récemment accueillis sur le plateau de Chips & Tips, la célèbre série d'Adobe TV dédiée à la diététique productivité. Au détour de cet épisode, Loïc Aigon et votre serviteur proposons une sorte de préambule aux techniques d'automatisation et de scripting dans la Creative Suite, avec quelques illustrations simples et directement accessibles aux néophytes. Vous y découvrirez notamment la version embryonnaire du script SwapItems utilisé pour permuter des objets dans une maquette InDesign…

So What's New in InDesign CS5.5 Scripting DOM

The interesting thing about tracking Scripting DOM changes from InDesign CS5 to InDesign CS5.5 is that this instantly reveals the main innovations of this ‘mid-cycle’ release —so that scripters can easily focus on the freshest features. The below PDFs offer you in a snap the tip of the iceberg: the new Article component and a bunch of new export options (HTMLExportPreference, EPubExportPreference, StyleExportTagMap, ObjectExportOption) that indicate the much greater integration of InDesign EPUB and digital publishing capabilities. Enjoy!

InDesign Scripting Forum: 25 ‘sticky’ posts [roundup]

The InDesign Scripting Forum is an ideal place to post scripting recipes and to address technical issues. I learn a lot from its famous contributors —Dave Saunders, Harbs, Jongware, Peter Kahrel, Kasyan Servetsky, Marijan Tompa… At odd times I post my own brainchilds. Here is a small selection of snippets and topics that I think are worthwhile.

Alphabetical Sort in JavaScript (and InDesign)

Surprisingly, JavaScript offers no easy way to alphabetize words in relevant order. Although the Array.sort() method is known to perform, by default, a lexicographical sort, you will find very quickly that the result is wrong in most real-life situations. Actually, the internal mechanism of JS sorting is confined to compare Unicode characters by their code points, so 'Z' (U+005A) comes before 'e' (U+0065), which itself comes before 'ç' (U+00E7), etc. Also, you have all noted with vexation that InDesign does not offer any alphabetical sort feature! Here is an experimental tool to help restore order in Latin alphabets.

On ‘everyItem()’ – Part 2

In the previous episode we learned that every scripting DOM object is in fact an object specifier, which acts like a path in the InDesign object tree. Collection's methods only allow us to build object specifiers. Invoking a property or a method provided by a specifier causes InDesign to send a “verb-first command” to the underlying receiver(s). We will now consider how this process impacts your code, what is returned into your script and how to deal with some side effects.

On ‘everyItem()’ – Part 1

Every collection in the scope of the InDesign Scripting DOM provides a method called everyItem. It remained undocumented until InDesign CS3, but scripting experts such as Dave Saunders had already pointed out its forcefulness and already knew how to exploit it. Here are some details about this esoteric syntax.

Operator Overloading with ExtendScript

Operator overloading in JavaScript is a controversial issue. Actually, this dangerous feature has been rejected in ECMAScript 4. However, ExtendScript allows you to override the behavior of many mathematical and logical operators on a class-by-class basis since CS2.

Binary JavaScript Embedment (CS4/CS5)

The jsxbin format (“Binary JavaScript”) is a boon for developers because it enables them to distribute a script without exposing its precious code. The ExtendScript ToolKit (ESTK) offers an Export to Binary feature which instantly converts a human-readable js(x) file into jsxbin. InDesign can then interpret this file as if it were a pure JavaScript. The only (boring!) problem is that the encoded script is not allowed to load a persistent session through the #targetengine directive. Here is a secret trick to bypass this limitation with a single encrypted file.

Can InDesign Script Rewrite Itself?

As illustrated by the YALT technique, it's easy —and powerful!— to let a script read its own bytes while it is running. We could even go further and get a script to update itself to achieve some advanced functionalities.

Yet Another Localization Technique (YALT) – Part 2

In the previous episode, we designed a light-weighted markup syntax for localized strings of any JavaScript based projects. Now let's see how to get a generic and simple access to those L10N data.

Yet Another Localization Technique (YALT) – Part 1

When you need your script's user interface to be translated according to the InDesign application locale, the common approch is to invoke the localization ExtendScript feature. The process is pretty straightforward, except that —in a verbose UI— you will have to create and manage many “localization objects”.
