I'm leaving this sinking ship. If you like this project, checked out the maintained version on GitLab.com.
UNDER CONSTRUCTION!
bookdown-mode is intended to become a major mode for editing bookdown and R Markdown documents.
Bookdown makes use of the feature-rich environment of recent pandoc versions, allowing for not just inline equations, but full-fledged LaTeX-style equation blocks. In addition it incorporates BibTeX-based citations and cross-references.
To highlight all of these new features in a nice way, I intend to fuse markdown-mode with some AUCTeX (for the LaTeX equation blocks) and add a couple of custom font-locks for the cross-references etc.
Since bookdown files, and R Markdown files in general, combine chunks of both markdown and R code, the use of bookdown-mode on its own is not intended. Instead, it's best used in combination with polymode. I would recommend to use my own fork of the mode, since it already relies bookdown-mode instead over markdown-mode.
In order to use it, add the following lines to your .emacs configuration file.
;; Adding the repository
(setq load-path (append '("PATH-TO-POLYMODE"
"PATH-TO-POLYMODE/modes"
"PATH-TO-BOOKDOWN-MODE" ) load-path))
;; Install/Load the packages
(require 'bookdown-mode)
(require 'poly-R)
(require 'poly-bookdown)
;; Tell Emacs to use ESS and bookdown-mode for .Rmd files.
(add-to-list 'auto-mode-alist '("\\.Rmd" . poly-bookdown+r-mode))Since this is the first major mode I'm authoring, there is MUCH stuff to be done and for now the code on the Master branch doesn't do anything markdown-mode isn't already doing. But since this mode is derived from markdown-mode, there is no harm (yet :)) using it. If you are curious about the current state of the project, head over to the develop branch!
For the time being I would recommend to enable the mathematical highlighting provided by the markdown-mode to have at least a low-level fontification of your equations. To do so, add the following line to your .emacs
(custom-set-variables '(markdown-enable-math t))This will color your inline equations. If you want to highlight your LaTeX-style equation blocks as well, insert $$ right before and after a block.
$$\begin{equation}
M_n = \max\left\{ X_1, \ldots, X_n \right\}
(\#eq:rescaling)
\end{equation}$$This package is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License, version 3, as published by the Free Software Foundation.
