Description

This layer adds markdown support to Spacemacs.

Features:

• markdown files support via markdown-mode
• Fast Github-flavored live preview via vmd-mode
• TOC generation via markdown-toc
• Completion of Emojis using company-emoji (still needs a way of showing, either using the emoji layer or having a proper font) 👏

BibTeX

For more extensive support of references with BibTeX files, have a look at the BibTeX layer.

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add markdown to the existing dotspacemacs-configuration-layers list in this file.

Configuration

Live preview

By default the built-in Emacs web browser is used to live preview a markdown buffer.

To use vmd (Github-flavored live preview) instead set the value of the variable markdown-live-preview-engine to vmd:

  dotspacemacs-configuration-layers '(
    (markdown :variables markdown-live-preview-engine 'vmd))

And install the executable with:

  npm install -g vmd

Additionally there is flymd package in chrome layer that allows to preview markdown buffer in Chrome. Please refer to chrome layer documentation for more information.

Automatic MMM-Mode Generation

To generate MMM-Modes for languages set the value of the variable markdown-mmm-auto-modes to a list of the languages. For languages where the mode name directly relates to the language name, use a string. Otherwise, use a list of `(“language” “mode”)`:

  dotspacemacs-configuration-layers '(
    (markdown :variables markdown-mmm-auto-modes '("c" "c++" "python" "scala" ("elisp" "emacs-lisp"))

Note: Spacemacs already defines the variable markdown-mmm-auto-modes to a bunch of languages. Consider opening a PR on the Spacemacs repository to add new languages instead of overriding the variable in your dotfile.

Usage

Generate a TOC

To generate a table of contents type on top of the buffer: SPC SPC markdown-toc-generate-toc RET
