||
* Description
|
||
This layer adds support for the [[http://wiki.portal.chalmers.se/agda/pmwiki.php][Agda]] programming language.
|
||
|
||
** Features:
|
||
- 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 configuration layer, add it to your =~/.spacemacs=. You will need to
|
||
add =agda= to the existing =dotspacemacs-configuration-layers= list in this
|
||
file.
|
||
|
||
** 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 =$PATH= and seen by Emacs. For
|
||
information about setting up =$PATH=, check out the corresponding section in the
|
||
FAQ (~SPC h SPC $PATH RET~).
|
||
|
||
By default the =agda-mode= executable bundled with most agda installations is
|
||
used to locate the agda-mode package. If you don't have it and want to use a
|
||
local agda-mode package, you can customize the layer variable =agda-mode-path=
|
||
to your needs. Set it to =nil= if =agda2.el= is already discoverable in Emacs'
|
||
load path, otherwise set it to the path at which =agda2.el= can be found. For
|
||
example,
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(agda :variables agda-mode-path "/some/path/to/agda2.el")
|
||
#+END_SRC
|
||
|
||
* 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~.
|
||
|
||
