To support completion for GHCi commands (like
:set etc.) in
To turn on GHCi commands completion in
inferior-haskell buffers, add
(add-hook 'inferior-haskell-mode-hook 'turn-on-ghci-completion)
You may also want to set
the list of additional argument to supply to
ghc-pkg. For example,
this variable can be used to specify which database (user or global)
or which package config file to use.
This package is developed for Emacs 24 and it probably only works with Emacs 24. In particular, we rely on lexical bindings, which have been introduced in Emacs 24, and on
pcomplete, which is effectively broken in 23.2.
Only the following commands are supported:
:show. It would be nice to have shell completion for
:!, for example.
The starred versions of the commands
:moduleare not supported, partly because I don't use them, and partly because, for example,
:moduleoffers completion only on the exposed modules in registered packages in both the global and user databases, and for these
:module *<mod>is meaningless.
:unsetsupport only a subset of all GHC flags: language extensions, warnings, and debugging options. Adding completion for other flags is trivial. It would be nice, however, to be able to generate the list of all GHC flags programmatically.
