[Discussion] Deprecate haskell-mode-contextual-space

[geraldus]

This is from online haskell-mode manual

4.2.5 Entering imports

If you have Haskell Interactive Mode enabled and a session open, you can write

import

And then hit SPC (running M-x haskell-mode-contextual-space) which will prompt a list of all modules, either installed modules or local project directory files. Then it’ll insert it and then format that module section.

haskell-mode-contextual-space^[1] seems not to be used at all these days and is not bound to any key sequence^[2]. It provides following functionality:

• prompt user to select module name when pressed SPC after import keyword (using haskell-complete-module-read)
  • it does not provide qualified import support
  • modules list comes from session
• echoes identifier info to mini-buffer (using haskell-process-do-try-info)
• it requires interactive haskell mode to be enabled and session to be present, otherwise it does nothing

Module import is simplified by auto completions. Identifier info in mini-buffer is questionable. I'd rather see identifier type signature. But since it is not used in any other function, not bound to any key sequence, and do not provide any unique feature should we drop it completely deprecate it along with haskell-mode-contextual-import-completion^[3]?

Agreed. Last time a guy tried to use it he was burned in #572. Just remove it, no deprecation needed.

[geraldus]

Will do in few hours

@gracjan by the way how long we keep obsolete code in?

[gracjan]

We do not have specific rules about deprecation.
