Painless is not quite painless. My team has been struggling with painless scripts due to a couple of reasons: 1. (as far as I know) it's not possible to execute scripts locally - it would be great to write unit tests; 2. painless misses some useful features like JSON parsing/stringifying. Other ecosytem tools would be great like LSP. Well, I started doing some experiments with ANTLR in order to come up with a tool that compiles JavaScript to Painless - using this we would get all the JS ecosystem like LSP and test runners. I'd like to check with more experienced people if there's a tool like that already or even if there's a plan from Elastic team or something to add this ecosystem to painless itself. Context: We've been using scripts as transformes in Watcher pipeline ---
