ive been using it for about 6 months 8 hrs a day with the elixir plugin yes it does understand syntax, but its atrocious with indentation, coupled with all the bugs from the ide like indexing forever, actually trying to index your home vs the project dir
i decided ultimately its not for me, too many issues ex. saving the elixir file i was editing but only in the ide, when the files i changed/saved were viewed in vi or emacs the changes werent there, it was like it didnt actually save the files but only in mem there this happened a few days ago!!! and then theres all the bloat, i really only use the ide for syntax highlighting, the hundreds of features needed in other programming languages are un-necessary in elixir imho atom is just an all around better editor,
