Use Vale in Emacs!
Adds support for editing Vale (Verified Assembly Language for Everest) files, and interacting with the prover.
Setup
Vale Mode requires Emacs 25 or newer.
It is distributed through MELPA.
-
Add the following to your init file (usually
.emacs
) if it is not already there:(require 'package) (add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t) (package-initialize)
-
Restart Emacs, then run M-x package-refresh-contents and M-x package-install RET vale-mode RET. Future updates can be downloaded using M-x list-packages U x y.
-
To be able to use the interactive portions of Vale, make sure to have
python3
on your path, and to set thevale-interact-path
to point tointeract.py
from vale.(setq-default vale-interact-path "/PATH/TO/interact.py")
-
To be able to quickly jump around between procedures, make sure to have
etags
on your path.
use-package
Alternate setup using use-package
makes your init file configuration extremely tidy, and also makes it easy to ensure that all the packages you want are automatically installed when on a new machine.
Use the following code in your init file to ensure that you've got use-package
(after the (package-initialize)
):
(eval-when-compile
(or (require 'use-package nil t)
(progn
(package-refresh-contents)
(package-install 'use-package)
(message "On a new system. Just installed use-package!"))))
Now, you can install vale-mode
simply by using the following declaration in your init file:
(use-package vale-mode
:ensure t
:custom
(vale-interact-path "/PATH/TO/interact.py")
:mode ("\\.vaf\\'" . vale-mode))
