This module provides Markdown support for Emacs.
Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).
Thus, “Markdown” is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML. See the Syntax page for details pertaining to Markdown’s formatting syntax. You can try it out, right now, using the online Dingus.
The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. While Markdown’s syntax has been influenced by several existing text-to-HTML filters, the single biggest source of inspiration for Markdown’s syntax is the format of plain text email. – John Gruber

1.2. Module flags
- Enables grip support (on <localleader> p), to provide live github-style previews of your markdown (or org) files.
- Flyspell has been configured not to spell check in code blocks, links, HTML tags or references.
This module has two soft dependencies: a linter and a compiler (for previewing markdown).
Out of the box, flycheck recognizes these checkers for markdown-mode and gfm-mode:
2.2. Markdown preview
This module requires a markdown compiler in order for
work. It will recognize and use one of the following executables, in this order
(you only need one):
- markedjs: a markdown compiler “built for speed”
- pandoc: the universal markup transpiler
- markdown: there are various flavors of this compiler. This module will look for these two:
- multimarkdown: a compiler for a language that is a superset of Markdown, with additional output formats and features.
Pandoc is the universal markup transpiler. It should be available through your system package manager. For example:
brew install pandoc
- Arch Linux:
pacman -S pandoc
The C implementation of Markdown.pl, called discount, is available through your OS’s package manager:
brew install discount
- Arch Linux:
pacman -S discount
The original perl script that discount is inspired from can be found on John Gruber’s website.
3.1. Markdown preview
markdown-preview is bound to <localleader> p. This will open a preview of
your compiled markdown document in your browser.
Alternatively, you can use
grip-mode through +grip.
4.1. Changing how markdown is compiled
markdown-preview is invoked (<localleader> p) it consults
markdown-command. Its default value (
#'+markdown-compile) will consult
+markdown-compile-functions: a list of functions that take three arguments:
the start and end point in the current buffer to use as input, and an output
buffer to insert the result in.
By default, the value of
'(+markdown-compile-marked +markdown-compile-pandoc +markdown-compile-markdown +markdown-compile-multimarkdown)
These functions will attempt to use the marked, pandoc and markdown executables, if available. Changing this variable will control how markdown is compiled.
;; Add a new one (add-hook '+markdown-compile-functions #'my-compile-function) ;; Or remove an existing one (remove-hook '+markdown-compile-functions #'+markdown-compile-markdown)
Otherwise, you can change
