idris2-mode's Introduction

idris2-mode for emacs

This is an emacs mode for editing Idris2 code.

It's a copy of (https://github.com/idris-hackers/idris-mode) mostly, for working with Idris2 in its present state. See that readme for more details.

Install it by running within your ~/.emacs.d directory:

$ git clone https://github.com/redfish64/idris2-mode

Then in your ~/.emacs.d/init.el file, add:

(add-to-list 'load-path "~/.emacs.d/idris2-mode/")
(require 'idris2-mode)

Here is what works so far:

M-n		idris2-next-error
M-p		idris2-previous-error

C-c C-a		idris2-proof-search
C-c C-c		idris2-case-dwim
C-c C-e		idris2-make-lemma
C-c C-l		idris2-load-file
C-c C-s		idris2-add-clause
C-c C-t		idris2-type-at-point

Note, if you use evil-mode, you'll probably want to use this to prevent a huge lag when editing files, see ProofGeneral/PG#427 (comment) for more details:

;;Fixes lag when editing idris code with evil
(defun ~/evil-motion-range--wrapper (fn &rest args)
  "Like `evil-motion-range', but override field-beginning for performance.
See URL `https://github.com/ProofGeneral/PG/issues/427'."
  (cl-letf (((symbol-function 'field-beginning)
             (lambda (&rest args) 1)))
    (apply fn args)))
(advice-add #'evil-motion-range :around #'~/evil-motion-range--wrapper)
