Adobe's ExtendScript toolkit is abyssmal. I find posts from 2008 referring to issues that have not changed even in CC2017. Do you think they are small issues I'm bitching about? I'll list 2. First, the toolkit only colours "var, return, for, foreach" and a bit more keywords and the strings, of course you can set up color schemes but those are limited and not colouring stuff. The second issue is auto-complete, it rarely kicks in and suggestions have 0 connection to what are you doing and are always the same. It doesn't recognize anything of what are you doing.

Probably in 2008 you had to program with the manual near you like writing assembler, now there's an improvement in 2017, they got a window named object browser or something like that that actually is a summarised portable manual that could've been easily transformed in auto-complete suggestions.

Adobe writes about this and I quote: "a complete integrated development environment". Although I will not write much scripts in it, I need to write a big one and thought about extracting that object data and putting it in a more capable javascript editor. LO and Behold what I discovered, the ExtendScript Toolkit that's supposed to edit Extended javascript and save it as jsx or jsxbin is almost completely (it has some dlls too) built using around 100 jsx files. It's the equivalent of building a js IDE to edit js.

Sorry for formatting, I'm on mobile, I tried.
