Doom-emacs: [BUG] Error on Markdown preview with Pandoc on Fish

Created on 3 Sep 2019 · 3Comments · Source: hlissner/doom-emacs

Describe the issue
After markdown-preview, browser opens a page saying /usr/bin/fish: invalid option -- 't'.

I have fish version 3.0.2 as my user shell, and I believe markdown-preview is trying to run pandoc (which is version 2.7.3).

I also tried installing marked, which failed with a similar error /usr/bin/fish: invalid option -- 'gfm'.

Steps to reproduce

M-x markdown-preview (or SPC m b)
File will open on the browser

Delete marked from your system and let me know if this fixes your issue with pandoc:

;; add to ~/.doom.d/config.el
(defun my-markdown-compile-pandoc (beg end output-buffer)
  "Compiles markdown with the pandoc program, if available.
Returns its exit code."
  (when (executable-find "pandoc")
    (call-process-region
     beg end shell-file-name nil output-buffer nil shell-command-switch
     "pandoc -f markdown -t html --standalone --mathjax --highlight-style=pygments")))
(advice-add #'+markdown-compile-pandoc :override #'my-markdown-compile-pandoc)
