Question

Please help me set up proper indentation in Emacs haskell-mode

When I’m trying to type down something like ADT or a record, I’m getting on the wrong column after pressing <ENTER>, and pressing <TAB> won’t switch to the right one until I enter either | or ‘;’!

data MyADT = Oh
           | Hi
           | Hello
             | <- the cursor is here again!

Trying to solve the problem I set

(define-key global-map (kbd "RET") 'reindent-then-newline-and-indent)

in my .emacs file, but it won’t indent the current line on pressing <enter> too!

Another strange behaviour: indentation of case

oneChar c =  case lookup c simpleEscapes of
  | <- what? here?!

Answer 1

I commented the line

;;(add-hook 'haskell-mode-hook 'turn-on-haskell-indent)

And now I’m getting a good “tab” behavior: at least, it allows me to choose a column and does not tie down me to the one it likes. But no auto-indent at all annoys me a little bit, so I’m hoping it is a temporary solution
