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..
