It can also export to lots of formats: LaTeX, PDF, Beamer, iCalendar (agendas), HTML, Markdown, ODT, plain text, man pages, and more complicated formats such as a set of web pages. + +This isn't just some afterthought either; it's a core part of the system and integrates very well. + +One file can be source code, automatically-generated output, task list, documentation, and presentation, all at once. + +Some use org-mode as their preferred markup format, even for things like LaTeX documents. The org-mode manual has an extensive [section on exporting][13]. + +#### 1.2 Getting started + +From any org-mode document, just hit C-c C-e. From there will come up a menu, letting you choose various export formats and options. These are generally single-key options so it's easy to set and execute. For instance, to export a document to a PDF, use C-c C-e l p or for HTML export, C-c C-e h h. + +There are lots of settings available for all of these export options; see the manual. It is, in fact, quite possible to use LaTeX-format equations in both LaTeX and HTML modes, to insert arbitrary preambles and settings for different modes, etc. + +#### 1.3 Add-on packages + +ELPA containts many addition exporters for org-mode as well. Check there for details. + +### 2 Beamer slides with org-mode + +#### 2.1 About Beamer + +[Beamer][14] is a LaTeX environment for making presentations. Its features include: + +* Automated generating of structural elements in the presentation (see, for example, [the Marburg theme][1]). This provides a visual reference for the audience of where they are in the presentation. + +* Strong help for structuring the presentation + +* Themes + +* Full LaTeX available + +#### 2.2 Benefits of Beamer in org-mode + +org-mode has a lot of benefits for working with Beamer. Among them: + +* org-mode's very easy and strong support for visualizing and changing the structure makes it very quick to reorganize your material. + +* Combined with org-babel, live source code (with syntax highlighting) and results can be embedded. + +* The syntax is often easier to work with. + +I have completely replaced my usage of LibreOffice/Powerpoint/GoogleDocs with org-mode and beamer. It is, in fact, rather frustrating when I have to use one of those tools, as they are nowhere near as strong as org-mode for visualizing a presentation structure. + +#### 2.3 Headline Levels + +org-mode's Beamer export will convert sections of your document (defined by headings) into slides. The question, of course, is: which sections? This is governed by the H [export setting][15] (org-export-headline-levels). + +There are many ways to go, which suit people. I like to have my presentation like this: + +``` +#+OPTIONS: H:2 +#+BEAMER_HEADER: \AtBeginSection{\frame{\sectionpage}} +``` + +This gives a standalone section slide for each major topic, to highlight major transitions, and then takes the level 2 (two asterisks) headings to set the slide. Many Beamer themes expect a third level of indirection, so you would set H:3 for them. + +#### 2.4 Themes and settings + +You can configure many Beamer and LaTeX settings in your document by inserting lines at the top of your org file. This document, for instance, defines: + +``` +#+TITLE: Documents and presentations with org-mode +#+AUTHOR: John Goerzen +#+BEAMER_HEADER: \institute{The Changelog} +#+PROPERTY: comments yes +#+PROPERTY: header-args :exports both :eval never-export +#+OPTIONS: H:2 +#+BEAMER_THEME: CambridgeUS +#+BEAMER_COLOR_THEME: default +``` + +#### 2.5 Advanced settings + +I like to change some colors, bullet formatting, and the like. I round out my document with: + +``` +# We can't just +BEAMER_INNER_THEME: default because that picks the theme default. +# Override per https://tex.stackexchange.com/questions/11168/change-bullet-style-formatting-in-beamer +#+BEAMER_INNER_THEME: default +#+LaTeX_CLASS_OPTIONS: [aspectratio=169] +#+BEAMER_HEADER: \definecolor{links}{HTML}{0000A0} +#+BEAMER_HEADER: \hypersetup{colorlinks=,linkcolor=,urlcolor=links} +#+BEAMER_HEADER: \setbeamertemplate{itemize items}[default] +#+BEAMER_HEADER: \setbeamertemplate{enumerate items}[default] +#+BEAMER_HEADER: \setbeamertemplate{items}[default] +#+BEAMER_HEADER: \setbeamercolor*{local structure}{fg=darkred} +#+BEAMER_HEADER: \setbeamercolor{section in toc}{fg=darkred} +#+BEAMER_HEADER: \setlength{\parskip}{\smallskipamount} +``` + +Here, aspectratio=169 sets a 16:9 aspect ratio, and the remaining are standard LaTeX/Beamer configuration bits. + +#### 2.6 Shrink (to fit) + +Sometimes you've got some really large code examples and you might prefer to just shrink the slide to fit. + +Just type C-c C-x p, set the BEAMER_opt property to shrink=15\. + +(Or a larger value of shrink). The previous slide uses this here. + +#### 2.7 Result + +Here's the end result: + + [![screenshot1](https://farm1.staticflickr.com/889/26366340577_fbde8ff266_o.png)][16] + +### 3 Interactive Slides + +#### 3.1 Interactive Emacs Slideshows + +With the [org-tree-slide package][17], you can display your slideshow from right within Emacs. Just run M-x org-tree-slide-mode. Then, use C-> and C-< to move between slides. + +You might find C-c C-x C-v (which is org-toggle-inline-images) helpful to cause the system to display embedded images. + +#### 3.2 HTML Slideshows + +There are a lot of ways to export org-mode presentations to HTML, with various levels of JavaScript integration. See the [non-beamer presentations section][18] of the org-mode wiki for details. + +### 4 Miscellaneous + +#### 4.1 Additional resources to accompany this post + +* [orgmode.org beamer tutorial][2] + +* [LaTeX wiki][3] + +* [Generating section title slides][4] + +* [Shrinking content to fit on slide][5] + +* A great resource: refcard-org-beamer See its [Github repo][6] Make sure to check out both the PDF and the .org file + +* A nice [Theme matrix][7] + +#### 4.2 Up next in my Emacs series… + +mu4e for email! + + +-------------------------------------------------------------------------------- + +via: http://changelog.complete.org/archives/9900-emacs-5-documents-and-presentations-with-org-mode + +作者：[John Goerzen][a] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) +选题：[lujun9972](https://github.com/lujun9972) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]:http://changelog.complete.org/archives/author/jgoerzen +[1]:https://hartwork.org/beamer-theme-matrix/all/beamer-albatross-Marburg-1.png +[2]:https://orgmode.org/worg/exporters/beamer/tutorial.html +[3]:https://en.wikibooks.org/wiki/LaTeX/Presentations +[4]:https://tex.stackexchange.com/questions/117658/automatically-generate-section-title-slides-in-beamer/117661 +[5]:https://tex.stackexchange.com/questions/78514/content-doesnt-fit-in-one-slide +[6]:https://github.com/fniessen/refcard-org-beamer +[7]:https://hartwork.org/beamer-theme-matrix/ +[8]:https://changelog.complete.org/archives/tag/emacs2018 +[9]:https://github.com/jgoerzen/public-snippets/blob/master/emacs/emacs-org-beamer/emacs-org-beamer.org +[10]:http://changelog.complete.org/archives/9900-emacs-5-documents-and-presentations-with-org-mode +[11]:https://github.com/jgoerzen/public-snippets/raw/master/emacs/emacs-org-beamer/emacs-org-beamer.pdf +[12]:https://github.com/jgoerzen/public-snippets/raw/master/emacs/emacs-org-beamer/emacs-org-beamer-document.pdf +[13]:https://orgmode.org/manual/Exporting.html#Exporting +[14]:https://en.wikipedia.org/wiki/Beamer_(LaTeX) +[15]:https://orgmode.org/manual/Export-settings.html#Export-settings +[16]:https://www.flickr.com/photos/jgoerzen/26366340577/in/dateposted/ +[17]:https://orgmode.org/worg/org-tutorials/non-beamer-presentations.html#org-tree-slide +[18]:https://orgmode.org/worg/org-tutorials/non-beamer-presentations.html
