| (org-export-string STRING FMT &optional DIR)
|
| Export STRING to FMT using existing export facilities.
| During export STRING is saved to a temporary file whose location
| could vary. Optional argument DIR can be used to force the

This function should be useful in user code, and can already reduce the
amount of code in ob-org.el and org-mime.el.

Subject: [PATCH] org-export-string -- exports a string of org-mode markup text
* lisp/org-exp.el (org-export-string): new function org-export-string
can be used to convert a string of test in org-mode markup to a
specified format
* contrib/lisp/org-mime.el (org-mime-htmlize): now using new
org-export-string function for exportation
* lisp/ob-org.el (org-babel-execute:org): now using new
org-export-string function for exportation
* doc/org.texi: Document the <c> cookie.
* lisp/org-exp.el (org-store-forced-table-alignment):
(org-export-remove-special-table-lines): Allow the "c" cookie for
table alignment.
* lisp/org-html.el (org-export-table-header-tags):
(org-export-table-data-tags): Add another %s format for the alignment.
(org-export-html-table-align-individual-fields): New option.
(org-format-org-table-html): Implement field-by-field alignment and
support centering.
(org-format-table-table-html): Make sure the new table tag formats
don't break this function.
* lisp/org-table.el (org-table-cookie-line-p):
(org-table-align): Allow for the <c> cookie.
* lisp/org.el (org-set-font-lock-defaults): Allow for the <c> cookie.
* org-exp.el (org-export-format-source-code-or-example): latex
formatting of source code blocks using the minted package
(org-export-plist-vars): Add :latex-minted property
(org-export-latex-minted): Ensure variable is defined
(org-export-latex-minted-langs): Ensure variable is defined
* org-latex.el (org-export-latex-minted): new variable
(org-export-latex-minted-langs): new variable
(org-export-latex-minted-with-line-numbers): new variable
(org-export-latex-minted):
* lisp/org-exp.el (org-export-language-setup): Fix Polish entries.
Hello.
There is no such named entity as ś. If you want to be 7bit clean
then use ś (or decimal ś).
Example:
{{{property(id)}}}
Will insert the ID property of current subtree if the Org buffer is
exported.
* lisp/org-exp.el (org-infile-export-plist): Define property macro
TINYCHANGE
* org-capture.el (org-capture-place-item): use `org-search-forward-unenclosed'
and `org-search-backward-unenclosed' and new variable `org-item-beginning-re'.
* org-list.el (org-item-beginning-re): regexp matching beginning of an item.
* org-exp.el (org-export-mark-list-ending): fix number of blank lines
inserted after a list.
* org-list.el (org-list-parse-list): fix case when `org-list-end-re'
would have an indentation greater than current list.
* org-html.el (org-export-html-preprocess): Remove unneeded insertion
of list end marker, as it is now handled by
`org-export-mark-list-ending'.
* org-html.el (org-export-as-html): Cleaner termination of lists.
* org-exp.el (org-export-mark-list-ending): New function to insert
specific markers at the end of lists when exporting to a backend not
using `org-list-parse-list'.
This function is called early in `org-export-preprocess-string',
while it is still able to recognize lists.
* org-latex.el (org-export-latex-lists): Better search for lists. It
now only finds items not enclosed and not protected.
* lisp/org-exp.el (org-export-preprocess-apply-macros): Fix the macro
argument parser.
The macro argument parser was swallowing white space after escaped commas.
* lisp/org-exp.el (org-export-with-LaTeX-fragments): New default t, which
now means to use MathJax processing for HTML. Also allow new value
`dvipng' to force the old image processing.
(org-infile-export-plist): Parse for MATHJAX setup line.
* lisp/org-html.el (org-export-html-mathjax-options): New option.
(org-export-html-mathjax-config): New function.
(org-export-html-mathjax-template): New option.
(org-export-html-preprocess): Call the LaTeX snippet processor with an
additional argument to declare special ways of processing.
(org-export-as-html): Bind the dynamical variable
`org-export-have-math'. Insert the MathJax script template when it is
needed by the document.
* lisp/org.el (org-preview-latex-fragment): Call `org-format-latex' with
the additional processing argument.
(org-export-have-math): New variable, for dynamic scoping.
(org-format-latex): Implement specific ways of processing. New
function argument for processing type.
(org-org-menu): Remove the entry to configure LaTeX snippet
processing.
MathJax is now the default for displaying math in a browser.
* contrib/lisp/org-wikinodes.el: New file.
* lisp/org-exp.el (org-export-preprocess-after-radio-targets-hook):
(org-export-define-heading-targets-headline-hook): New hooks.
* lisp/org.el (org-modules): Add entry for org-wikinodes.el.
(org-font-lock-set-keywords-hook): New hook.
(org-open-at-point-functions): New hook.
(org-find-exact-headling-in-buffer):
(org-find-exact-heading-in-directory): New functions.
(org-mode-flyspell-verify): Better cursor position for checking if
flyspell should ignore a word.
* lisp/org.el (org-link-search-must-match-exact-headline): New option.
(org-link-search-inhibit-query): New variable.
(org-link-search): Search for exact headline match in Org files
* doc/org.texi (Internal links): Document the changes in internal links.
Internal links used to do a fuzzy text search for the link text. This
patch changes the behavior for Org files. Here a link [[My Target]]
now searches for an exact headline match, i.e. for a headline that
does look like "* My Target", optionally with TODO keyword, priority
cookie and tags.
The new option `org-link-search-must-match-exact-headline' is
`query-to-create' by default. This means that a failed link search
will offer to create the headline as a top-level headline at the end
of the buffer. This corresponds to a wiki-like behavior where missing
targets are automatically created. If you do not like this behavior,
change the option to t.
* lisp/org-exp.el (org-export-format-source-code-or-example): escape
underscores in code block names on latex listings export
* lisp/org-latex.el (org-export-latex-listings-w-names): make export
of code block names to latex optional
This is a second patch in a series that makes some straightforward
corrections to a number of docstrings. Each change is normally to:
- correct a typo, or
- fix up hyperlinks to function or variable names, or
- ensure slightly better conformance with the documentation guidelines
and tips given in the Elisp manual
No attempt is made to provide missing docstrings or document arguments.
Cheers,
Phil
* lisp/ob.el (org-babel-get-src-block-info): ensure that we don't
match (and return info for) source blocks without a language
* lisp/org-exp.el (org-export-replace-src-segments-and-examples):
updated source code block regexp so that the presence of a language
can be explicitly checked. Also now raising an error when a source
block does not have a language.
Of course, an updated patch is attached.

Subject: [PATCH] add short-names to #+captions with support for latex export
captions specified with the following syntax
#+CAPTION: [shortname]{longname}
will have their short and longnames handled appropriately.
Thanks to Robert Cunningham for suggesting this feature.
* lisp/org-exp.el (org-export-attach-captions-and-attributes): adding
a shortname attribute to caption strings under the symbol name
org-caption-shortn.
* lisp/org-latex.el (org-export-latex-tables): handling caption short
names on table export
(org-export-latex-convert-table.el-table): handling caption short
names on table.el type table export
(org-export-latex-links): handling caption short names on link/image
export
(org-export-latex-format-image): now takes an optional argument
specifying a caption short name
* lisp/org-exp.el (org-export-handle-table-metalines): this function
removes table specific meta-lines, now that we aren't wiping
everything that looks remotely like a comment at the end of the
export process we have to be sure to catch all of the specific lines
in org-exp.el
* lisp/org-exp.el: (org-export-select-backend-specific-text) Properly
get rid of #+Backend and #+ATTR_Backend specifics to backends not
matching the one we're exporting to.
