do you need a separate LaTeX installation to export org mode files to pdf?

do you need a separate LaTeX installation to export org mode files to pdf?

I'm a longtime LaTeX user and a more recent org mode user. So I've always
had LaTeX installed on any computer on which I was using org mode. I'd like
to introduce org mode to a co-worker unfamiliar with the whole concept of
plain text files, markup, and literate programming, etc.  Would they need
to install LaTeX too, or is org mode self-contained and able to export to
pdf without LaTeX an friends installed?

Thanks.

Yes, they'd need to have a LaTeX distribution installed on their system. In
my experience, installing the full latest version of TexLive is the easiest
way.

Hello Christopher

I have a docker image with LaTeX installed in order not to "pollute" my
local filesystem with the 4GB of additional libraries a full LaTeX
installation requires.
If your co-worker is a software developer you could use that approach.

Here is mi Dockerfile for LaTeX:

FROM ubuntu:xenial
MAINTAINER Martin Alsinet <martin@alsinet>

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update -q
RUN apt-get install -y texlive-full gnuplot python-pygments
RUN apt-get clean
RUN rm -rf /var/lib/apt/lists/*

Save that in a file named *Dockerfile* in a blank folder and run *docker
build -t latex .*
This will create a docker image named latex with all the libraries and
executables neatly tucked away.
Then, in order to use it, you can save the following script in
~/bin/pdflatex

#!/bin/sh
export PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin
docker run --rm \
           -v $(pwd):$(pwd) \
           -v ~/.ssh:/root/.ssh \
           -w $(pwd) \
           latex \
           pdflatex $@
rm *.log *.aux
rm -f *.ent
rm -Rf _minted-*

With that you can use the *pdflatex* command as usual, and docker creates a
temporary container (docker run --rm ...) from the image, runs the pdflatex
command and removes the container after execution.

Hi all,

For years, my approach was to install texlive-full. But that meant
blocking me for around 2 hours.

Recently, I threw together a minimal Dockerfile to enable org-to-pdf
export. Here's the gist of it:

    FROM ubuntu:xenial
    RUN apt update && apt install -y software-properties-common
    RUN apt install -y texlive-latex-extra cm-super

I also install Emacs and some project specific stuff on top of it. In
the end, the built Docker image is only 2.19GB.
If you don't care for Docker, you can just install the above minimal
packages with sudo.

regards,
Oleh

You /could/ use latexonline.  I think it even supports bibtex.

    https://github.com/aslushnikov/latex-online

Here’s a minimal example.

    * TODO headline
     *bf* /emph/ etc.

     | a |


     #+begin_src emacs-lisp
       (let ((str (mapconcat 'identity
                 '("tar -cj %f" "|"
                   "curl -L --post301 --post302 --post303 -F file=@-"
                   "\"https://latexonline.cc/data?command=%latex&target=%f\""
                   "> %b.pdf")
                 '" ")))
         (setq org-latex-pdf-process (list str)))
     #+end_src

How to include all document dependencies (e.g. images) in the tar file is
left as an exercise for the motivated reader.  One could probably make a
"dumb" but effective solution by finding all instances of certain file
types in the project folder.

Needless to say, if you use this with real-life documents, you will
probably want to set up your own instance of latexonline.

Good to know people are more and more moving away from document writers
that tie them to speciific graphical user interfaces and going more
towards formats which are easy to read and edit even in plain text. ;)

Well, you only need LaTeX for exporting. But if you do want to go
immediately to teach him how to export to LaTeX or to PDF in the first
lesson, then: yes, you need LaTeX to export to PDF.

I have also been writing a guide for Org mode and LaTeX for researchers
and writers, it's currently in Brazilian Portuguese and isn't as broad
as the info page in GNU Emacs itself, see [1]. Also, [2] has a more
advanced example of a work being done using (mostly) Org mode but also
LaTeX, BibTeX, TikZ and abnTeX2.
