Strange syntax highlighting

[mhwombat]

I am using idris-mode 0.9.19. I got it from Melpa Stable, but I think it's the same version that's on GitHub. I am seeing a strange effect with syntax highlighting. When I first load in Idris source file, only certain keywords are in colour.

Then, If I load the file into the Idris REPL, identifiers are in colour, but the last character of each identifier is not in colour.

Here is a minimal emacs configuration which reproduces this behaviour.

;; No startup screen
(setq inhibit-startup-screen t)

;; open with single window
(add-hook 'emacs-startup-hook 'delete-other-windows)

;; Repos
(require 'package) ;; This is built-in
(add-to-list 'package-archives
             '("gnu" . "http://elpa.gnu.org/packages/") t)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)
(add-to-list 'package-archives
             '("melpa-stable" . "http://stable.melpa.org/packages/") t)
(package-initialize)
;; (package-refresh-contents)

Thanks for the report! Two things:

• We get close to all syntax highlighting from the compiler. That’s why you only get colors after loading a file

• The syntax highlighting certainly looks off by one.

What version of idris do you have?

Hmm. Actually now that I look at it, I think our melpa-stable is quite out of date. Could you try plain melpa and let me know what happens?

Upgrading to the plain melpa version fixed it. Thank you!
