14 The release of Org-mode 8.0 (and the git repository master branch, as of [[https://orgmode.org/cgit.cgi/org-mode.git/commit/?id%3D1cac3127c2f810e83fcc1203f1dd2b15250a687e][commit 1cac3127c]])
15 uses a new export framework, developed by Nicolas Goaziou. This document provides
16 information on general changes to Org, as well as the steps needed to update your
17 configuration properly.
19 If the instructions below do not help solving your problem, please ask any
20 question on the [[https://orgmode.org/community.html][mailing list]]. Keep in mind that the new export framework is under heavy
21 development, and posting to the mailing list will help not only to resolve your issues,
22 but also make sure that documentation is properly udpated for the benefit of others with
25 This page serves as an upgrade guide for the changes widely affecting users. /Please/
26 refer to the [[file:exporters/ox-overview.org][new exporter overview]], which contains an up to date list of
27 Org-mode exporters, and links to backend-specific setup and usage details.
29 * Files moved to =contrib/=
31 These files have been moved to the =contrib/= directory.
33 - =org-colview-xemacs.el=
38 - =ox-taskjuggler.el= (was org-taskjuggler.el)
39 - =ox-freemind.el= (was org-freemind.el)
41 If you were using them, you need to [[https://orgmode.org/manual/Installation.html][add the =contrib/lisp= directory]]
42 of the Org distribution to the Emacs =load-path=.
45 * Original announcement of the new exporter
47 The most comprehensive overview of the new exporter may be found in Nicolas' merge
48 announcement [[http://article.gmane.org/gmane.emacs.orgmode/65574][in this email]] to the mailing list. Please scan the post, as you may find
49 answers to your questions there.
51 * Updating global export configuration options
53 Global export options start with the =org-export-*= prefix, most of them
54 are in the =ox.el= file.
56 Most generic export options should not require any changes. If
57 you find that a generic option is useless or broken or badly documented in
58 the manual, please report it to the list.
60 * Backend-specific configuration options
62 Backend-specific options are now defined via the convention =ox-backend-*=. For example:
64 - =org-html-*= for =HTML= and live in =ox-html.el=
65 - =org-latex-*= for =LaTeX= and live in =ox-latex.el=
68 There is a new variable =org-export-backends= which controls what backends
69 are loaded when you lauch Org. By default, the =ASCII=, =HTML= and =LaTeX=
70 are loaded; in contrast with the old exporter behavior, others will need to be explicitly
71 loaded in order to use them. See the [[Upgrading your setup][upgrade]] section for instructions.
73 ** HTML-specific changes
75 Some html-specific options were renamed more signficantly or deleted. Examine this
76 table and update accordingly:
78 | Org 7.9.3f (maint) | Master (8.0) |
79 |----------------------------------------+----------------------------------------|
80 | org-export-html-style | org-html-head |
81 | org-export-html-style-extra | org-html-head-extra |
82 | org-export-html-style-default | org-html-head-include-default-style |
83 | org-export-html-style-include-scripts | org-html-head-include-scripts |
84 | org-export-htmlized-org-css-url | org-org-htmlized-css-url (in ox-org.el |
85 |----------------------------------------+----------------------------------------|
86 | org-export-html-headline-anchor-format | Deleted |
87 | org-export-html-date-format-string | Deleted |
88 | org-export-html-content-div | Deleted |
89 | org-export-html-html-helper-timestamp | Deleted |
91 ** Org publishing specific changes
92 Some changes also specifically affect =org-publish-project-alist= settings. The publishing
93 functions are not loaded until the corresponding backend has been loaded. You need to
94 update =org-publish-project-alist= and to use the function from the new publishing engine
97 | Old publishing engine | New publishing engine |
98 |--------------------------+----------------------------|
99 | org-publish-org-to-html | org-html-publish-to-html |
100 | org-publish-org-to-org | org-org-publish-to-org |
101 | org-publish-org-to-latex | org-latex-publish-to-latex |
105 To specify a style for the project =:style= keyword changes to =:html-head=
107 If something does not work, please report it on the mailing list.
111 * Upgrading your setup
113 The practical implication for users upgrading from Org-mode < version 7.9.4f is two-fold:
115 - You must search your configuration for the existence of varaibles starting with
116 =org-export-= and change their names (e.g. =org-export-html-validation-link= is now
117 =org-html-validation-link=). /See sections below changes specific to the HTML and
118 Publishing backends/.
120 - If you use exporters in addition to =ASCII=, =HTML=, and/or =LaTeX=, you need to load them
121 explicitly in your config via one of two ways (refer to [[http://article.gmane.org/gmane.emacs.orgmode/65574][Nicolas' announcement]], section
122 3 on Installation, for explanation of the two methods):
124 *1: Load exporter upon first export execution per session*
126 setq org-export-backends (quote (
133 *2: Loading all listed exporters upon Emacs startup*
138 (require 'ox-taskjuggler)
141 *Note:* Please stick to /one/ of the above two methods!
143 ** Using Org 7.9.3f or earlier versions of Org
145 For users who used the new exporter prior to its integration into the current master
146 branch, here are some additional steps you may need to do in order to upgrade properly:
148 1. Issue =make clean= before =git pull= and any changes to your
151 2. If you had already been using the new exporter from contrib, you should
152 remove the following lines from your local.mk:
153 : ORG_ADD_CONTRIB = org-e-*
155 3. Export engine renamed from =org-export= to =ox=
157 4. Backend requires renamed =org-e-*= to =ox-*=
159 5. All backend specific variables and functions renamed:
160 - =org-export-*= to =org-*= (e.g. org-html-xml-declaration, ..)
161 - =org-e-*= to =org-*= (e.g. org-latex-classes, org-ascii-bullets, ..)
163 6. Generic export variables retain the name =org-export-*=,
164 (e.g. org-export-dispatch-use-expert-ui,
165 org-export-filter-headline-functions, ..)
167 7. =org-latex-to-pdf-process= renamed =org-latex-pdf-process=
169 8. This is a guess, export snippets and backend symbols renamed:
170 - =e-<backend>= to =<backend>=
172 Again, please refer to [[http://mid.gmane.org/876229nrxf.fsf@gmail.com][Nicolas' announcement]] about the merge for more details.
175 * New global keywords
179 In the exporting of a table of contents, options only allowed for setting the
180 level of the deepest table of contents headline, like so:
186 Upon export, only first and second level headlines would be included in the generated
187 table of contents. With the new exporter, a dedicated =#+TOC= now exists which allows for
188 futher customization: adding table of contents, lists of tables, and lists of listings at
189 specific locations during export.
197 See the [[https://orgmode.org/manual/Table-of-contents.html][Table of contents]] section in the manual for more information.
203 Export snippets are a generalization of ~@<tag>~ concept, which has
204 been removed, and the inline version of ~#+begin_backend...#+end_backend~ blocks.
206 Their syntax is ~@@backend:value~ where ~backend~ is the targetted
207 export backend (e.g. ~html~) and ~value~ can contain anything but
210 When export is done with ~backend~, the snippet is replaced with
211 ~value~, otherwise it is removed. Whitespace characters around
212 the construct are never deleted.
214 ** Footnote definitions
216 A footnote definition (not inline) can now be ended with two
217 consecutive blank lines.
219 As a consequence, multiple paragraphs inside can be written
220 normally, separated with blank lines, instead of relying on the
223 ** Org-mode per-file options
225 - The =#+STYLE= option is now specified with =#+HTML_HEAD=
227 - Using =#+SETUPFILE: file= versus =#+INCLUDE: "file".=
229 =#+INCLUDE:= keyword requires quotes around the file name. Those
230 are optional in =#+SETUPFILE:=.
232 There is now also a clear difference between these two statements.
233 The first will only read keyword statements like =#+TODO:= and use
234 this to set up the current file. The second will pull in the entire
235 content of the file during export. The =#+INCLUDE:= statement will
236 make every headline in the included file will be a child of the
237 headline containing the include keyword. You can overwrite this
238 behaviour with =:minlevel= num parameter.
240 - Attribute lines now take plists (similar to [[https://orgmode.org/worg/org-contrib/babel/][Babel code block syntax]]):
242 : #+attr_latex: :width 5cm
243 : #+attr_beamer: :options width=5cm
244 : #+attr_html: :width 200px
246 *TIP:* To upgrade from old =attr_html= lines with verbatim HTML
247 attribute syntax, you could try a Perl one-liner like the following,
248 replacing =filename.org= with your file (or a bunch of files with
249 =*.org= if you're feeling adventurous -- no warranty, make sure
250 you're backed up first!).
252 : perl -i.bak -pe "s/([a-z]+)=(\"|')(.*?)\2/:\1 \3/g if /^#\+attr_html/i" filename.org
254 - Beamer backend now interprets nested headline levels as blocks instead
255 of lists. For more guidance, see [[file:exporters/beamer/ox-beamer.org][this page]].
