* Description
This layer adds support for the [[http://wiki.portal.chalmers.se/agda/pmwiki.php][Agda]] programming language.
** Some features:
2015-06-10 16:44:30 +00:00
- Faces redefined to correctly play with themes.
- Spacemacs bindings to Agda's interactive tools.
*This layer is in construction, it needs your contributions and bug reports.*

* Install
** Layer
To use this contribution add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(agda))
#+END_SRC
** Agda
Quick instructions to install Agda assuming you have cabal installed:
#+BEGIN_SRC sh
cabal install alex happy "cpphs < 1.19" agda
#+END_SRC
Then check that =agda= is available on your =PATH= and seen by Emacs.
* Key bindings
The key bindings of this layer don't follow the Spacemacs conventions,
we opted to a simple transcription of stock Agda mode key bindings to
Spacemacs leader key.
All Agda specific bindings are prefixed with the major-mode leader
~SPC m~.

| ~SPC m =~ | Show constraints. |
| ~SPC m ?~ | Show all goals. |
| ~SPC m ,~ | Shows the type of the goal at point and the currect context. |
| ~SPC m .~ | Shows the context, the goal and the given expression's inferred type. |
| ~SPC m a~ | Simple proof search. |

| ~SPC m c~ | Refine the pattern variables given in the goal. |
| ~SPC m d~ | Infers the type of the given expression. |
| ~SPC m e~ | Show the context of the goal at point. |
| ~SPC m f~ | Go to the next goal, if any and activate goal-navigation micro-state. |
| ~SPC m h~ | Compute the type of a hypothetical helper function. |
| ~SPC m l~ | Load current buffer. |
| ~SPC m n~ | Computes the normal form of the given expression, using the scope of the current goal or, if point is not in a goal, the top-level scope. |
| ~SPC m o~ | Shows all the top-level names in the given module. |
| ~SPC m r~ | Refine the goal at point. |
| ~SPC m s~ | Solves all goals that are already instantiated internally. |
