IDE-Haskell works only with Haskell projects. When you open Cabal project in Atom, or simply open a Haskell source file, IDE-Haskell will start automatically.
After saving the current file the check and linter processes will be executed.
After processes are finished the results can be seen in output panel. You can
see different kind of results by switching
buttons. If you click on message's file name in output panel, Atom will open
this file and put cursor near problem that triggered output message.
Check results can also be seen in left editor gutter (near line numbers) as icons. If you hover mouse pointer over such an icon, a tooltip will be shown with problem description. Results are highlighted inside editor as well, so you can easily determine where the problem is.
You can get type of any expression and get info on any symbol.
There are two options to do so.
First one is to hover mouse pointer over any Haskell source in editor, or any selection. By default, this will show type for expression/selecton under cursor. You can change this behavior to show info for symbol, or disable it completely in IDE-Haskell settings.
Another option is to use keyboard to get type/info under cursor. No default bindings are specified, but you can specify them in IDE-Haskell settings.
See Configuration for more information.
Autocompletion facilities have been moved to autocomplete-haskell package.
Please install it if you want autocompletion.
You can use
stylish-haskell utility to indent pragmas, imports and data type
definitions. Simply select
Prettify from Haskel IDE menu to apply
stylish-haskell to current file.
$ apm install language-haskell haskell-ghc-mod ide-haskell autocomplete-haskell
Package is fully configurable via Edit → Preferences → Packages → ide-haskell → Settings
You will likely need to specify full paths to
stylish-haskell, if it is not in
PATH, at the very least.
You might also want look into configuring haskell-ghc-mod: haskell-ghc-mod README
