Aloha Nicolas,
Nicolas Goaziou n.goaz...@gmail.com writes:
Hello,
I've changed the attribute syntax for tables, images and lists in
e-latex back-end (new exporter). New this back-end conforms to the
syntax used by Babel and every other back-end.
I've also added support for matrix editing.
Here's an excerpt from the documentation in org-e-latex.el:
Table export can be controlled with a number of attributes (through
ATTR_LATEX keyword).
- The main one is the `:mode' attribute, which can be set to
`table', `math', `inline-math' and `verbatim'. In particular,
when in `math' or `inline-math' mode, every cell is exported
as-is and the table will be wrapped in a math environment. Also,
horizontal rules are ignored. These modes are particularly
useful to write matrices. Default mode is stored in
`org-e-latex-default-table-mode'.
- The second most important attribute is `:environment'. It is the
environment used for the table and defaults to
`org-e-latex-default-table-environment' value. It can be set to
anything, including tabularx, longtable, array,
bmatrix...
- `:float' attribute defines a float environment for the table.
Possible values are `sidewaystable', `multicolumn' and `table'.
- `:width' and `:align' attributes set, respectively, the width of
the table and its alignment string.
- `:booktabs', `:center' and `:rmlines' values are booleans. They
toggle, respectively booktabs usage (assuming the package is
properly loaded), table centering and removal of every horizontal
rule but the first one (in a table.el table only).
- `:math-prefix', `:math-suffix' and `:math-arguments' are string
which will be inserted, respectively, before the table within the
math environment, after the table within the math environment,
and between the macro name and the contents of the table. The
latter attribute is necessary to matrix macros that require more
than one argument (i.e. qbordermatrix).
Plain lists accept two optional attributes: `:environment' and
`:options'. The first one allows to use a non-standard environment
(i.e. inparaenum). The second one allows to specify optional
arguments for that environment (square brackets are not mandatory).
Images accept `:float', `:placement' and `:options' as attributes.
`:float' accepts a symbol among `wrap', `multicolumn', and
`figure', which defines the float environment for the table (if
unspecified, an image with a caption will be set in a figure
environment). `:placement' is a string that will be used as
argument for the environment chosen. `:options' is a string that
will be used as the optional argument for includegraphics macro.
Here are some example to illustrate the changes, in particular in the
table area:
#+begin_src org
#+LATEX_HEADER:
\usepackage{amsmath}\usepackage{booktabs}\usepackage{mathtools}\usepackage{rotating}
* Tables
#+NAME: my-matrix
#+attr_latex: :mode math :environment array
#+attr_latex: :math-prefix \\left( :math-suffix \\right)
| l | r |
| a | b |
|-+-|
| c | d |
This is a reference to matrix [[my-matrix]].
#+attr_latex: :mode math :environment matrix
#+attr_latex: :math-prefix M = \\left( :math-suffix \\right)
| a | b |
|---+---|
| c | d |
#+attr_latex: :mode verbatim
| a | b |
|---+---|
| c | d |
#+attr_latex: :booktabs nil :align |r|l| :float sidewaystable
| 123 | 123 |
|-+-|
| 1 | 1 |
Some inlined matrix
#+attr_latex: :mode inline-math :environment bsmallmatrix
| a | b |
|---+---|
| c | d |
. As you can see.
Eventually some bordered matrix:
#+attr_latex: :mode math :environment bordermatrix
| | C_1 | C_2 |
|-+-+-|
| L_1 | a | b |
| L_2 | c | d |
* Images (from manual)
#+caption: The black-body emission of the disk around HR 4049
#+name: fig:SED-HR4049
#+attr_latex: :options 5cm,angle=90
[[./img/sed-hr4049.pdf]]
#+attr_latex: :float wrap :placement {r}{0.4\\textwidth} :options
width=0.38\\textwidth
[[./img/hst.png]]
#+end_src
I think this is an improvement. Thanks!
Would it be possible to add a :font attribute for tables? I'd like to be
able to say, e.g., :font \\footnotesize and have \footnotesize appear
between the float and table environments, near \centering in the LaTeX
output.
All the best,
Tom

No. Attributes only apply on a single list not on a whole list type.
Though, it's easy to implement with filters. For example:
#+begin_src emacs-lisp
(defun my-latex-inline-plain-lists (plain-list backend info)
(when (org-export-derived-backend-p backend 'e-latex)
(replace-regexp-in-string
\\`begin{\\(itemize\\)} inparaitem
(replace-regexp-in-string
end{\\(itemize\\)}\\' inparaitem plain-list nil nil 1)
nil nil 1)))
(add-to-list 'org-export-filter-plain-list-functions
'my-latex-inline-plain-lists)
#+end_src
