* Attrap: ATtempt To Repair At Point

This is an Emacs minor mode which automates the application of

hints in messages reported through flymake or flycheck.

[[https://melpa.org/packages/attrap-badge.svg]]

[[https://stable.melpa.org/#/dante][https://stable.melpa.org/packages/attrap-badge.svg]]

Attrap! provides a single entry point to attempt to fix the error at

point.

Invoke the command ~attrap-attrap~ when point is on a flymake or flycheck error,

and check the results.  Attrap! currently comes with fixers for

~emacs-lisp~, [[https://github.com/jyp/dante/][~dante~]] and ~hlint~. Support for other

checkers can be added dynamically (See ~M-x customize-group attrap~ for the documentation).

* Installation with ~use-package~:

#+BEGIN_SRC elisp

(use-package attrap

  :ensure t

  :bind (("C-x /" . attrap-attrap))) ;; use any binding of your choice

#+END_SRC

* Configuration of the ~hlint~ checker

Attrap requires a flymake checker for hlint. It should be setup by

adding the appropriate hook to the haskell mode:

#+begin_src elisp

  (add-hook 'haskell-mode-hook

            (defun my/haskell-hook ()

              (require 'attrap)

              (require 'flymake-flycheck)

              (flymake-mode)

              (add-hook 'flymake-diagnostic-functions 'attrap-flymake-hlint nil t)))

#+end_src

Unfortunately there is no direct support for flycheck at the moment.

# , you can chain activate the hlint

# checker in addition to the dante checker by calling

# ~flycheck-add-next-checker~ as follows:

# #+BEGIN_SRC elisp

#   (flycheck-add-next-checker 'haskell-dante '(info . haskell-hlint))

# #+END_SRC

* Note for GHC users

Attrap assumes that GHC outputs unicode symbols in error messages,

which will happen only if $LANG is set to a proper value, such as

#+BEGIN_SRC shell

export LANG=en_US.UTF-8 

#+END_SRC
