Readme for hindent-5.0.1
[back to package description]hindent 
Extensible Haskell pretty printer. Both a library and an executable.
Install
$ stack install
Usage
hindent is used in a pipeline style:
$ cat path/to/sourcefile.hs | hindent > outfile.hs
Emacs
In
elisp/hindent.el
there is hindent-mode, which provides keybindings to reindent parts of the
buffer:
M-qreformats the current declaration. When inside a comment, it fills the current paragraph instead, like the standardM-q.C-M-\reformats the current region.
To enable it, add the following to your init file:
(add-to-list 'load-path "/path/to/hindent/elisp")
(require 'hindent)
(add-hook 'haskell-mode-hook #'hindent-mode)
Vim
The 'formatprg' option lets you use an external program (like hindent) to
format your text. Put the following line into ~/.vim/ftplugin/haskell.vim
to set this option for Haskell files:
setlocal formatprg=hindent
Then you can format with hindent using gq. Read :help gq and help 'formatprg' for more details.
Note that unlike in emacs you have to take care of selecting a sensible buffer region as input to hindent yourself. If that is too much trouble you can try vim-textobj-haskell which provides a text object for top level bindings.
Atom
Basic support is provided through atom/hindent.coffee. Mode should be installed as package into .atom\packages\${PACKAGE_NAME},
here is simple example of atom package.
