pasp-mode

A major mode for editing Potassco Answer Set Programs files (.lp).

From the Potassco website:
Answer Set Programming (ASP) offers a simple and powerful modeling language to solve combinatorial problems. With our tools you can concentrate on an actual problem, rather than a smart way of implementing it.

Features

• Syntax highlighting
• Commenting functionality
• Run clingo from emacs

Keybindings

Not so many at the moment:

• C-c C-b Call clingo with the current buffer
• C-c C-x Call clingo with the current buffer as encoding and some user provided instance

Installation

Melpa

The Potassco ASP mode is available through the MELPA repository. This is the recommended way to install the pasp-mode.

You can either install pasp-mode by hand with: M-x package-install [RET] pasp-mode [RET]

or place the following snippet into your Emacs init file:

(unless (package-installed-p 'pasp-mode)
  (package-refresh-contents)
  (package-install 'pasp-mode))

Manually

Download the pasp-mode.el file from this repository. Either put it into your emacs load path and call (require 'pasp-mode) in your init file or load it directly with (load "~/path/to/pasp-mode.el")

Afterwards opening an .lp file triggers pasp-mode or call M-x pasp-mode within an open asp file.

Todo

• Smart indentation based on nesting deepth
• Refactoring of predicates/variables (complete buffer and #program parts)
• Color compilation output
• Smart rearrange of compilation output (predicates separated, table...)
• yas-snippet for rules; constraints; soft constraints; generation?
