* lisp/ox-latex.el: (org-latex-template): When no date is provided or
the export option date is nil, the empty '\date{}' string is no
longer included in the exported latex document.
The default behaviour for ox-latex was to include an empty date line as
'\date{}'. This empty date line can affect more complex latex templates
when the date is for example set by the template on compilation, or when
the date command is overwritten entirely. In this new patch, the date
line is omitted from the exported document.

|

|

When this variable is non-nil, Org will use the value of
|
||
CUSTOM_ID property, NAME keyword or Org target as the key for the
|
||
\\label commands generated.
|
||
|
||
By default, Org generates its own internal labels during LaTeX
|
||
export. This process ensures that the \\label keys are unique
|
||
and valid, but it means the keys are not available in advance of
|
||
the export process.
|
||
|
||
Setting this variable gives you control over how Org generates
|
||
labels during LaTeX export, so that you may know their keys in
|
||
advance. One reason to do this is that it allows you to refer to
|
||
various elements using a single label both in Org's link syntax
|
||
and in embedded LaTeX code.
|
||
|
||
For example, when this variable is non-nil, a headline like this:
|
||
|
||
** Some section
|
||
:PROPERTIES:
|
||
:CUSTOM_ID: sec:foo
|
||
:END:
|
||
This is section [[#sec:foo]].
|
||
#+BEGIN_EXPORT latex
|
||
And this is still section \\ref{sec:foo}.
|
||
#+END_EXPORT
|
||
|
||
will be exported to LaTeX as:
|
||
|
||
\\subsection{Some section}
|
||
\\label{sec:foo}
|
||
This is section \\ref{sec:foo}.
|
||
And this is still section \\ref{sec:foo}.
|
||
|
||
A non-default value of `org-latex-reference-command' will change the
|
||
command (\\ref by default) used to create label references.
|
||
|
||
Note, however, that setting this variable introduces a limitation
|
||
on the possible values for CUSTOM_ID and NAME. When this
|
||
variable is non-nil, Org passes their value to \\label unchanged.
|
||
You are responsible for ensuring that the value is a valid LaTeX
|
||
\\label key, and that no other \\label commands with the same key
|
||
appear elsewhere in your document. (Keys may contain letters,
|
||
numbers, and the following punctuation: `_' `.' `-' `:'.) There
|
||
are no such limitations on CUSTOM_ID and NAME when this variable
|
||
is nil.
|
||
|
||
For headlines that do not define the CUSTOM_ID property or
|
||
elements without a NAME, Org will continue to use its default
|
||
labeling scheme to generate labels and resolve links into proper
|
||
references."

|
||
- Calls to \\usepackage for all packages mentioned in the
|
||
variables `org-latex-default-packages-alist' and
|
||
`org-latex-packages-alist'. Thus, your header definitions
|
||
should avoid to also request these packages.
|
||
|
||
- Lines specified via \"#+LATEX_HEADER:\" and
|
||
\"#+LATEX_HEADER_EXTRA:\" keywords.
|
||
|
||
If you need more control about the sequence in which the header
|
||
is built up, or if you want to exclude one of these building
|
||
blocks for a particular class, you can use the following
|
||
macro-like placeholders.
|
||
|
||
[DEFAULT-PACKAGES] \\usepackage statements for default packages
|
||
[NO-DEFAULT-PACKAGES] do not include any of the default packages
|
||
[PACKAGES] \\usepackage statements for packages
|
||
[NO-PACKAGES] do not include the packages
|
||
[EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
|
||
[NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
|
||
|
||
So a header like
|
||
|
||
\\documentclass{article}
|
||
[NO-DEFAULT-PACKAGES]
|
||
[EXTRA]
|
||
\\providecommand{\\alert}[1]{\\textbf{#1}}
|
||
[PACKAGES]
|
||
|
||
will omit the default packages, and will include the
|
||
#+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
|
||
to \\providecommand, and then place \\usepackage commands based
|
||
on the content of `org-latex-packages-alist'.
|
||
|
||
If your header, `org-latex-default-packages-alist' or
|
||
`org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
|
||
AUTO will automatically be replaced with a coding system derived
|
||
from `buffer-file-coding-system'. See also the variable
|
||
`org-latex-inputenc-alist' for a way to influence this mechanism.
|
||
|
||
Likewise, if your header contains \"\\usepackage[AUTO]{babel}\"
|
||
or \"\\usepackage[AUTO]{polyglossia}\", AUTO will be replaced
|
||
with the language related to the language code specified by
|
||
`org-export-default-language'. Note that constructions such as
|
||
\"\\usepackage[french,AUTO,english]{babel}\" are permitted. For
|
||
Polyglossia the language will be set via the macros
|
||
\"\\setmainlanguage\" and \"\\setotherlanguage\". See also
|
||
`org-latex-guess-babel-language' and
|
||
`org-latex-guess-polyglossia-language'.
|
||
|
||
The sectioning structure
|
||
------------------------
|
||
|
||
The sectioning structure of the class is given by the elements
|
||
following the header string. For each sectioning level, a number
|
||
of strings is specified. A %s formatter is mandatory in each
|
||
section string and will be replaced by the title of the section.
|
||
|
||
Instead of a cons cell (numbered . unnumbered), you can also
|
||
provide a list of 2 or 4 elements,
|
||
|
||
(numbered-open numbered-close)
|
||
|
||
or
|
||
|
||
(numbered-open numbered-close unnumbered-open unnumbered-close)
|
||
|
||
providing opening and closing strings for a LaTeX environment
|
||
that should represent the document section. The opening clause
|
||
should have a %s to represent the section title.
|
||
|
||
Instead of a list of sectioning commands, you can also specify
|
||
a function name. That function will be called with two
|
||
parameters, the (reduced) level of the headline, and a predicate
|
||
non-nil when the headline should be numbered. It must return
|
||
a format string in which the section title will be added."

1. Verbatim

2. Listings
|

3. Minted
|

4. Engraved
|
||
|
||
The first two options provide basic syntax
|

highlighting (listings), or none at all (verbatim).
|
||
|
||
When using listings, you also need to make use of LaTeX package
|
||
\"listings\"e. The \"color\" LaTeX package is also needed if you
|
||
would like color too. These can simply be added to
|
||
`org-latex-packages-alist', using customise or something like:
|
||
|
||
(require \\='ox-latex)
|
||
(add-to-list \\='org-latex-packages-alist \\='(\"\" \"listings\"))
|
||
(add-to-list \\='org-latex-packages-alist \\='(\"\" \"color\"))
|
||
|
||
There are two further options for more comprehensive
|
||
fontification. The first can be set with,
|
||
|
||
(setq org-latex-src-block-backend \\='minted)
|
||
|
||
which causes source code to be exported using the LaTeX package
|
||
minted as opposed to listings. If you want to use minted, you
|
||
need to add the minted package to `org-latex-packages-alist', for
|
||
example using customize, or with
|
||
|
||
(require \\='ox-latex)
|
||
(add-to-list \\='org-latex-packages-alist \\='(\"newfloat\" \"minted\"))
|
||
|
||
In addition, it is necessary to install pygments
|
||
\(URL `https://pygments.org>'), and to configure the variable
|
||
`org-latex-pdf-process' so that the -shell-escape option is
|
||
passed to pdflatex.
|
||
|
||
The minted choice has possible repercussions on the preview of
|
||
latex fragments (see `org-preview-latex-fragment'). If you run
|
||
into previewing problems, please consult
|
||

There is quite a lot of flexibility in what this preamble can be,
|

as long as it:
|
||
- Loads the fvextra package.
|
||
- Loads the package xcolor (if it is not already loaded elsewhere).
|
||
- Defines a \"Code\" environment (note the capital C), which all
|
||
\"Verbatim\" environments (provided by fvextra) will be wrapped with.
|
||
|
||
In the default value the colors \"EFD\" and \"EfD\" are provided
|
||
as they are respectively the foreground and background colours,
|
||
just in case they aren't provided by the generated preamble, so
|
||
we can assume they are always set.
|
||
|
||
Within this preamble there are two recognised macro-like placeholders:
|
||
|
||
[FVEXTRA-SETUP]
|
||
|
||
[LISTINGS-SETUP]
|
||
|
||
Unless you have a very good reason, both of these placeholders

||
should be included in the preamble.

FVEXTRA-SETUP sets fvextra's defaults according to
|

`org-latex-engraved-options', and LISTINGS-SETUP creates the
