miss the old version of InDesign API. Can I still find it?

I do maintain https://www.indesignjs.de/indesignapi/ and updated the ExtendScript API for various reasons. The old one was generated in 2014 with a toolchain I can't keep running. And its underlying website technology is outdated. I won't be maintaining two sites, sorry.

I did try to make the transition painless; it has the same information presentation and a ton of new features and goodies. 

What's new:

• No frames. One static page per object, so deep links, back button, Ctrl+F all work.
• Ctrl+K searches all 28.000+ members. O filters the object list, P/E/M shortcuts jump to properties, events, methods.
• Cleaner data — mashed-up types like boundsKind:BoundingBoxLimits resolved, value ranges and measurement units shown as such, optional parameters marked consistently.
• Hierarchy on every page: what contains this object, what it contains, which preferences hang off it.
• ExtendScript / UXP switch.
• TypeScript declarations for VS Code autocomplete, plus a ScriptUI variant.
   

If you still need InDesign CS6 docs and the old layout these are still online https://www.indesignjs.de/indesignapi/indesign8/ Historical reference only — frozen at CS6, For a currently shipping InDesign it may be a decade out of date.

 Later, I found item.move(undefined, [-x, 0]); in someone else's example. I'm curious about the purpose of undefined.

Hi ​@dublove , I think the new API is better once you get used to it. If you go to PageItem you can scroll down to the move(to, by) method. The available properties are listed first, followed by the methods 

https://www.indesignjs.de/indesignapi/indesign/PageItem.html

So with a page item selected:

//a selected object
var s = app.activeDocument.selection[0]
//the top layer
var tl = app.activeDocument.layers.firstItem()

//Moves to -— move to the [1,1] x,y position
s.move([1,1])

//Moves by -— move by [1,1] from the starting position
s.move(undefined, [1,1])

//Move to a different layer, the top layer in this case
s.move(tl)

Works for me just fine. What do you mean by incorrect?

The new version is better, move method used two args “to” and “by” only one is used at a time. See https://www.indesignjs.de/indesignapi/indesign/PageItem.html#m-move

For old version you could check the internet archive.
