Please see the homepage for Intero for Emacs.

Default key bindings

Key binding | Description --- | --- M-. | Jump to definition C-c C-i | Show information of identifier at point C-c C-t | Show the type of thing at point, or the selection C-u C-c C-t | Insert a type signature for the thing at point C-c C-l | Load this module in the REPL C-c C-c | Evaluate the selected region in the REPL C-c C-r | Apply suggestions from GHC C-c C-k | Clear REPL C-c C-z | Switch to and from the REPL

Enabling intero

To enable intero in all haskell-mode buffers by default, enable intero-global-mode, by using M-x customize or by adding (intero-global-mode 1) to your Emacs start-up files.

Intero will then activate for all projects, and for files without a stack.yaml, it will assume the "global" project. If you want to use an alternate stack yaml configuration file (for example, when developing for multiple GHC versions), use M-x intero-stack-yaml to switch file. When switching configuration, you will asked whether you want to preserve this choice across emacs sessions for the given project.

Whitelisting/blacklisting projects

Some users prefer to enable Intero selectively. The custom variables intero-blacklist and intero-whitelist are provided for this purpose, and are honoured by intero-global-mode:

If the parent directory of a Haskell file is listed in intero-blacklist, then intero will not be enabled for that file, unless a parent directory of that file is also listed in intero-whitelist. In other words, whitelist entries take precedence. You can therefore blacklist / to disable intero in all projects unless they are whitelisted.

Intero for IDE writers

Please see the TOOLING.md file for how to use Intero to integrate your own editor..
