Pandoc set jobname for LaTeX PDF export - pdf

Is there a way to tell Pandoc to set \jobanme to a specific value while converting and compiling single markdown file to PDF (via LaTeX)? -Preferably the name of the source *.md file.
background:
I have my own LaTeX document class defined which uses \jobname.
It prints it in the document footer, so that it's easy for me to find source file/repo having a printed PDF.
I set jobname in my compile scripts as pdfLaTeX argument.
I am currently trying to use my document class as LaTeX template for documents processed by Pandoc from Markdown source. It seems, Pandoc sets \jobname always as 'input'.
I can set any variable in Markdown's yaml header which may be then printed into PDF, but being able to set it based on true md file name will be much less error prone.

I solved my problem by redefining my LaTeX template and using sourcefile pandoc variable instead of \jobname in case of using pandoc.

Pandoc: generate compilable .tex from markdown

I have started using Markdown to write my Latex PDFs, and so far I am impressed by the amount of boilerplate it takes away.
However, I find Markdown not as expressive as Tex, and therefore in some situations would like to write the document in Markdown, convert to tex, then add some Latex-only stuff and only then convert to PDF.
However, converting .md to .tex with Pandoc does not yield an compilable file: it only contains the body of the file, not the "document setup".
Example, the following .md file:
```haskell
data Expr = I Int
```
Converts to:
\begin{Shaded}
\begin{Highlighting}[]
\KeywordTok{data} \DataTypeTok{Expr} \FunctionTok{=} \DataTypeTok{I} \DataTypeTok{Int}
\end{Highlighting}
\end{Shaded}
Obviously this is missing some stuff like the document class, start of document and the imported packages. Is there any way to generate this complete file instead of just the body? Or if not, can anyone at least tell me what package the Shaded, Highlighting, KeywordTok, DataTypeTok and FunctionTok commands are pulled from? Then I can add these imports myself.
Pandoc creates small snippets by default. Invoke it with the --standalone (or -s) command line flag to get a full document.

How to compile all .md files in a directory into a single .pdf with pandoc, while preserving YAML header data?

I have a directory of .md documents that each contain a YAML header specifying document title, author, date, categories,tags, etc. The directory contains journal entries and the filenames are simply the date of the entry.
I have no trouble using pandoc to generate a PDF for each .md file, however I'm looking for a way generate a single PDF in book or memoir format with each .md document's title field as a chapter in the table of contents, arranged by the date value. Ideally, the date would also appear in the table of contents, but that's not critical if the individual chapters will also display that information.
I haven't been able to find a way to do this as pandoc seems to ignore all but the first YAML header when concatenating multiple documents. One possible solution I can think of is to convert all relevant YAML header info to markdown headings and then demote existing headings in each .md document. But I'm not sure how to do this or if this is even the best approach. I was also looking at the R bookdown package, but it also uses markdown headers for chapters and not sure if it can be adapted to use YAML header info.
what is the easiest way to accomplish what I need? Thanks.
Your idea as outlined in your question is a good way to go:
The demoting of the title to a header can be done via a filter, e.g. a Lua filter if you are using pandoc >2.0. The following assumes that you are using the current version 2.0.6:
demote.lua:
-- List is available since pandoc 2.0.4
local List = require 'pandoc.List'
function Header (h)
h.level = h.level + 1
return h
end
function Pandoc (doc)
local title = doc.meta.title
local header = pandoc.Header(1, title)
doc.blocks = {header} .. doc.blocks
return doc
end
Now run the following command to create your pdf:
for f in /path/to/docs/*.md; do
pandoc --lua-filter=demote.lua -t markdown
printf "\n" # insert empty line between articles
end | pandoc -o combined.pdf

Table of contents sidebar in Sphinx LaTeX PDF

I am generating a LaTeX document from Sphinx, and converting it to PDF using pdflatex (from MikTeX). The document is missing a table of contents in the sidebar of the PDF viewer.
If I add manually \usepackage{hyperref} to the tex file, it works. But how can I tell Sphinx to do it in the conf.py project file? There is no (evident) related option in the latex output options.
Thanks!
Section 2.5.3 Customizing the rendering of the Sphinx document mentions:
LaTeX preamble
Additional commands may be added as preamble in the generated LaTeX file. This is easily done by editing file conf.py:
f = open('latex-styling.tex', 'r+');
PREAMBLE = f.read();
latex_elements = {
# The paper size ('letterpaper' or 'a4paper').
#'papersize': 'a4paper',
# The font size ('10pt', '11pt' or '12pt').
#'pointsize': '10pt',
# Additional stuff for the LaTeX preamble.
'preamble': PREAMBLE
}
This will copy the contents of file latex-styling.tex (in same directory as conf.py) to the generated LaTeX document. For instance, if latex-styling.tex reads:
% My personal "bold" command
\newcommand{\mycommand}[1]{\textbf{#1}}
the generated LaTeX document becomes:
% Generated by Sphinx.
\def\sphinxdocclass{report}
\documentclass[a4paper,10pt,english]{sphinxmanual}
% snip (packages)
% My personal "bold" command
\newcommand{\mycommand}[1]{\textbf{#1}}

Other options
The configuration file conf.py lets you further tune the rendering with LaTeX. Please consult http://www.sphinx-doc.org/en/stable/config.html#options-for-latex-output for further instructions.
A more direct way of adding content rather than inserting it in a separate file (say, latex-styling.tex), is to specify if verbatim. The next subsection in the documentation mentions this for a specific package typo3:
TYPO3 template
We want to stick as much as possible to default rendering, to avoid having to change the LaTeX code generation from Sphinx. As such, we choose to include a custom package typo3 (file typo3.sty) that will override some settings of package sphinx. To include it automatically, we simply use the preamble option of conf.py:
latex_elements = {
# Additional stuff for the LaTeX preamble.
'preamble': '\\usepackage{typo3}'
}
It's better to contain your styling options in a separate latex-styling.tex file that you can include using the preamble key via an f.read(). That way you don't have to update conf.py. Compartmentalization is usually better.

Inkscape "PDF + Latex" export

I'm using inkscape to produce vector figures, save them in SVG format to export them later as "PDF + Latex" much in the vein of TUG inkscape+pdflatex guide.
Trying to produce a simple figure, however, turns out to be extremely frustating.
The first figure
is an example of the figure I would like to export in the form of "PDF + Latex" (shown here in PNG format).
If I export this to a PDF figure without latex macros the PDF produced looks exactly the same, except for some minor differences with the fonts used to render the text.
When I try to export this using the "PDF + Latex" option the PDF file produced consists on a PDF document of 2 pages (again as .png here):
This, of course, does not looks good when compiling my latex document. So far the guide at TUG has been very helpful, but I still can't produce a working "PDF + Latex" export from inkscape.
What am I doing wrong?
I worked around this by putting all the text in my drawing at the top
select text and then Object -> Raise to top
Inkscape only generates the separate pages if the text is below another object.
I asked this question on the Inkscape online discussion page and got some very helpful guidance from one of the users there.
This is a known bug https://bugs.launchpad.net/ubuntu/+bug/1417470 which was inadvertently introduced in Inkscape 0.91 in an attempt to fix a previous bug https://bugs.launchpad.net/inkscape/+bug/771957.
It seems this bug does two things:
The *.pdf_tex file will have an extra \includegraphics statement which needs to be deleted manually as described in the link to the bug above.
The *.pdf file may be split into multiple pages, regardless of the size of the image. In my case the line objects were split off onto their own page. I worked around this by turning off the text objects (opacity to zero) and then doing a standard PDF export.
If you can execute linux commands, this works:
# Generate the .pdf and .pdf_tex files
inkscape -z -D --file="$SVGFILE" --export-pdf="$PDFFILE" --export-latex
# Fix the number of pages
sed -i 's/\\\\/\n/g' ${PDFFILE}_tex;
MAXPAGE=$(pdfinfo $PDFFILE | grep -oP "(?<=Pages:)\s*[0-9]+" | tr -d " ");
sed -i "/page=$(($MAXPAGE+1))/,\${/page=/d}" ${PDFFILE}_tex;
with:
$SVGFILE: path of the svg
$PDF_FILE: path of the pdf
It is possible to include these commands in a script and execute it automatically when compiling your tex file (so that you don't have to manually export from inkscape each time you modify your svg).
Try it with an illustration that is less wide.
Alternatively, use a wider paperwidth setting.

How to change header ("Contents") of automatic TOC when using Pandoc?

When converting markdown to pdf with pandoc (version 1.12.1) the ToC option adds an english header: "Contents".
Since my document is in Dutch, I would like to be able to put the Dutch equivalent of contents there. But unfortunately I couldn't find any configuration options for this, neither did I found clues in the default.latex file.
My query:
pandoc -S --toc essay.md --biblio "MCM Essay.bib" --csl apa.csl -o mcm.pdf
I'm using windows
I use MIKTex, like in the pandoc instructions
The string "Contents" is not supplied by pandoc, but by latex (which pandoc calls to create the PDF).
Try adding
-Vlang=dutch
to your command line. This will be passed to latex in the documentclass options, and LaTeX will provide the right string.
Adding
-V toc-title="My Custom TOC Header"
to the pandoc command line will also work. See https://pandoc.org/MANUAL.html#variables-set-automatically.
