New method have following features:
dabbrev
expansionOld method does not provided completions for pragma names and words inside comments and strings. Also it fetches completions by synchronous REPL query, this will hang Emacs for a while if REPL is busy. New method fallbacks to dabbrev expansions immediately in this case, though the result is worst. Old method does not provide completions for local names (e.g. defined in
let
blocks) and haskell keywords (e.g. "import", "where", etc.), and new method fallbacks to dabbrev expansions in case REPL returned no completions, so it is now possible to auto-complete local names and keywords too. Finally, is there is no haskell session (hence REPL is not available) new method also fallbacks to dabbrev expansions.
