    copied!<p>Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in Sweave (Sweave = R + LaTeX)? </p> <p>For instance, I would like to move to the beginning of a code block (&lt;&lt;>>), hit a keystroke, and have the contents of the environment hidden from view.</p> <p>Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize R environments.</p> <p>I also tryed org-mode that works great for folding/unfolding but, do not support the LaTeX highlighting code for expression like: \cite{}; \ref{}; \ce{} ...</p> <p>Best Riccardo</p> <p><strong>--EDIT--</strong></p> <p>I tried for some day to use emacs-folding-mode but, because I work on a very long code (more than 2000 rows), folding mode "goes crazy" and for example misunderstand the mining of some special character (i.e. $), that has very different use both in R than LaTeX. I think the problem is intrinsic to Sweave, because in the same buffer I have R code and LaTeX code together.</p> <p>So, now I'm testing emacs outline minor mode. But when I move through R from LaTeX (and vice versa) all the outlined part were unfolded despite I write in my .emacs:</p> <pre><code>(defun turn-on-outline-minor-mode () (outline-minor-mode 1)) (add-hook 'ess-mode-hook 'turn-on-outline-minor-mode) (add-hook 'LaTeX-mode-hook 'turn-on-outline-minor-mode) (add-hook 'latex-mode-hook 'turn-on-outline-minor-mode) (setq outline-minor-mode-prefix "\C-c\C-o") </code></pre> <p>Do you have any suggestions??</p> <p>Regards</p> <p>--EDIT 2--</p> <p>It seems to work:</p> <pre><code>(load "folding" 'nomessage 'noerror) (folding-mode-add-find-file-hook) (add-hook 'LaTeX-mode-hook 'folding-mode) (add-hook 'ess-mode-hook 'folding-mode) (folding-add-to-marks-list 'ess-mode "#{{{ " "#}}}" " ") </code></pre> <p>I don't know if is right that, when you leave the chunk, it is automatically unfolded.</p>
