• #### Creating a PDF with source code highlighting

From Beliavsky@21:1/5 to All on Thu Mar 10 07:19:31 2022
I would like to collect my Fortran tweets https://twitter.com/fortrantip into a PDF where the codes are in boxes with syntax highlighting. What software would you recommend for creating such a document?

I used LaTeX decades ago. It's powerful, but I have forgotten how to use it.

I was going to suggest Lout, but that is even more of a niche approach
and you still have to learn the language ;). How about a literate
programming tool such as noweb, which can be used from the
WYSIWYG Lyx editor...

I can get Fortran syntax highlighting in HTML by pasting code at http://hilite.me/ , which does recognize Fortran among other languages. Presumably I could find a program that does this. Explanatory text can be added before the HTML block. Once I have an
HTML file with text and code, there are ways to convert HTML to PDF.

Last year, I replaced the LaTeX lstlisting package by the minted package
in my documents:
http://tug.ctan.org/macros/latex/contrib/minted/minted.pdf

It is based on Pygments:
https://pygments.org/

I use Latex quite a bit and the listlisting package is really nice. I do not know minted.

@beliavsky, we ought to be able to get up and running with Latex again ;). It is not at all difficult, unless you want to do sophisticated things.

Sounds something ripe for MS Word mail merge via Excel perhaps.

Michel Olagnon distributed, at one time, a "tops" program,
which produced a color-highlighted postscript listing from Fortran source.

I can't find a link now. :-(

I might be able to find a copy, contact me if all else fails. :-)

(If you have access to /glade, there might be a copy under ftools.)

Do not know of a perfect solution out of the box, but know some places I would look.

I have used many utilities over time but some like f90ppr appear to be gone, or have not been kept up to date (enscript, ...) and you are posting modern syntax, so some that are up to date or nearly or still being updated that are non-commercial include
lfortran, which can generate colorized output and emacs and vim, and the highlighters used primarily by extended markdown.

LFortran is under development and most likely to do submodules and more recent features properly, there are a lot of examples of how to extract the highlighted text from vim and emacs, I think the shell script by Steve Kinzler called colorize is a good
example for getting HTML from vim without knowing vim, pandoc should be able to convert an extended markdown file but you might have to install the colorizers as separate packages, .... there are other pretty printers and colorizers that are parts of
commercial compilers (so depends on what you have) and colorizers (mostly for supporting markdown variants) that are useable as seperate packages.

Did you find what you wanted?

Since the editors and web forums often support highlighters.

github and ford and doxygen are all using Fortran highlighters that might be seperate packages as well.

Did not expect the Olagnon site to disappear. There was quite a bit there still linked to by other sites like the Fortran Wiki

One example using pandoc(1) on a linux box with bash(1). Make the Fortran file into an extended markdown file by adding fortran and  header and footer and use pandoc(1) to make and Adobe PDF file. read the PDF file into an HTML file using <IFRAME
. IFRAME gives you more control over geometry than <A....>. Could just do it as a markdown file and convert to HTML, etc. LOTS of options to play with with pandoc. Requires latex to be installed underneath for this particular pandoc command. Not a
very robust script, but it shows the steps.

#!/bin/bash
set -x
FFILE=${1:-/tmp/dice.f90} ( echo 'fortran' cat$FFILE
echo ''
) >/tmp/show.md
pandoc /tmp/show.md -s -o /tmp/fortran.pdf --highlight-style=kate -V geometry:margin=1in
cat >/tmp/show.html <<\EOF

lfortran fmt code.f90 |ansi2html >code.html

worked well with several modern Fortran files for coloring it; ansi2html is at

https://raw.githubusercontent.com/pixelb/scripts/master/scripts/ansi2html.sh

Did not see a way to write HTML directly from lfortran, although I thought there was one.

Thanks for this and your other suggestions. I emailed Michel Olagnon at Michel dot Olagnon at ifremer dot fr , but it bounced. It would be nice if someone who
has saved his tools can upload them. I may request this at Fortran Discourse in a week.

Here is a minimalist LaTeX document to start with. Under ubuntu, you
need the package python3-pygments. And you can compile the LaTeX file with:

I ran into difficulties using TeXnicCenter on WIndows (I was supposed to run Latex with some option). So I tried the example with the listings package. Here is the Tex code:

\usepackage{listings}

Just an alternative, mind you :).
