Actually, many of the advanced text editors offer plugins that replicate a variety of the functionality you mention. To better answer your question, I am forced to reveal the text editor I prefer (please do not take this comment as a slant to any other text editor): vim. For vim, there are several plugins that provide completion functionality (for various languages)[1]. There are things to deal with Java imports specifically[2]. (I don't know what you mean by fixing build rules.) Hey, there are even plugins meant to facilitate whole IDE functionality for some languages[3]. Personally, I avoid things like Java so I have less of a use-case for IDEs anyway. Specifically, I code in C and Haskell (and a touch of by-hand llvm-ir for fun). In C, automatic imports and the like, I do not even wish for (since it is so necessary for me to completely understand the function calls I make, I need to read the docs quite commonly which mention the header for #inclusion). And, for Haskell, I'm constantly prototyping in ghci, so I learn what I need anyway. In neithr of these languages do I feel it is helpful enough for me to desire such things. Having said that, I understand that many people disagree; not too long ago, there was a small uproar that Haskell did not have a proper IDE yet. And I am exposed to IDEs at $DAYJOB, but if anything, that has further soured me towards them. To all their own, text editors and IDEs alike; I think I'm likely to stick to my text editor :) [1] https://stackoverflow.com/questions/5169638/autocompletion-in-vim https://stackoverflow.com/questions/5169638/autocompletion-i...
