This page describes how to enable Vala syntax highlighting and code browser support in GNU Emacs. vala-mode is based on csharp-mode.
If You have package.el (included in Emacs 24 by default) -- just use http://marmalade-repo.org/
- M-x package-install vala-mode
Download vala-mode.el in your ~/.emacs.d/
Add the following snippet to your ~/.emacs
(add-to-list 'load-path (expand-file-name "~/.emacs.d")) (autoload 'vala-mode "vala-mode" "Major mode for editing Vala code." t) (add-to-list 'auto-mode-alist '("\\.vala$" . vala-mode)) (add-to-list 'auto-mode-alist '("\\.vapi$" . vala-mode)) (add-to-list 'file-coding-system-alist '("\\.vala$" . utf-8)) (add-to-list 'file-coding-system-alist '("\\.vapi$" . utf-8))
This is an optional configuration which is nice if you want to use Emacs Code Browser (ECB) and the CEDET package together with vala-mode. When you have successfully installed these packages as described on their homepages, you may use the C# semantics to get the wanted functionality also for Vala. It may not be perfect, but hopefully sufficient:
(add-hook 'vala-mode-hook #'wisent-csharp-default-setup)
This file is packaged in Debian GNU/Linux as vala-mode-el.
A patch to change constructs like
`(lambda (x) (foo x ',(f a b c)))
into closures like
(let ((fabc (f a b c))) (lambda (x) (foo x facb)))
is available on the branch lexical in the repository git://anonscm.debian.org/collab-maint/vala-mode-el.git
