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.
