Pig mode for Emacs

pig-mode is an Emacs major mode for editing Pig scripts. Currently it supports syntax highlighting and indentation for Pig versions 0.2 to 0.11. It also supports a local grunt shell as well as snippets. We track the changes to Pig syntax and try to support new Pig features ASAP.

PS. This project was originally hosted on sourceforge.net; we still maintain the page there, but from now on all new changes will be pushed to github first.

Installation

Package Installation

The easiest way is to install the ELPA package from MELPA with M-x package-install RET pig-mode. All dependencies are automatically installed.

Manual Installation

To install pig-mode manually, clone the repository:

git clone https://github.com/motus/pig-mode

Put it somewhere emacs knows to look for it and in your .emacs file, add this:

(require 'pig-mode)

Configuration

Set variables in .emacs or with customize-group RET pig RET (this works only after pig-mode has been loaded).

(setq pig-executable "/path/to/pig-0.11.1/bin/pig")
(setq pig-executable-options '("-x" "local"))
(setq pig-executable-prompt-regexp "^grunt> ")
(setq pig-indent-level 4)
(setq pig-version "0.11.1")

Add the following to set up processing snippets for yasnippet:

(autoload 'pig-snippets-initialize "pig-snippets" nil nil nil)
(eval-after-load 'yasnippet '(pig-snippets-initialize))
