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..

Issues

Issues are split into low/medium/high priorities which dictates which ones will be implemented first.
