Hi everyone,
Thanks for the tips in using export filters for code blocks. I thought I
would share my current solution. The goal was to export all the code blocks
in an org-file to files systematically named part1/script-%d.py where %d is
a number. I didnot want to tangle exactly, because I wanted to avoid naming
the code block tangle files.
Then, I wanted to insert a pdf link that would open the file, after the
syntax highlighted code.
I wanted this because it is not convenient to copy and paste the
syntax-highlighted code into an editor. I teach from the pdf that is
generated, and it would be convenient to just open the code, edit and rerun
to explore solutions.
So, here is the solution:
At the top of my orgfile, I have this definition which creates a pdf link.
#+LATEX_HEADER: \newcommand{\LaunchBinary}[2]{%
#+LATEX_HEADER: % #1: layer name,
#+LATEX_HEADER: % #2: link text
#+LATEX_HEADER: \leavevmode%
#+LATEX_HEADER: \pdfstartlink attr{/C [0.9 0 0] /Border [0 0 2]} user {
#+LATEX_HEADER: /Subtype /Link
#+LATEX_HEADER: /A <<
#+LATEX_HEADER: /F <<
#+LATEX_HEADER: /DOS (#1)
#+LATEX_HEADER: >>
#+LATEX_HEADER: /S /Launch
#+LATEX_HEADER: >>
#+LATEX_HEADER: } #2%
#+LATEX_HEADER: \pdfendlink%
#+LATEX_HEADER: }
Then, I use the code snippet below to export the file to latex. It is
stored in a noexport section at the end of the document. basically I set a
counter, and wrote a filter function for src blocks. the function captures
the lines between the first and last (first is \begin{minted}... and last
is \end{minted} in this case. I write those lines to a file named according
to the counter, and finally insert \LaunchBinary... into the string
returned by the filter. everything else in this let block is just
fine-tuning the latex packages, and export behavior.
(let (
;; these packages are loaded in the latex file
(org-latex-default-packages-alist
'(("utf8" "inputenc" nil)
("T1" "fontenc" nil)
("" "fixltx2e" nil)
("" "natbib" t)
("" "url" t)
("" "graphicx" t)
("" "textcomp" t)
("" "underscore" t)
("" "amsmath" t)
("version=3" "mhchem" t)
("tight,pdftex" "web" nil)
("" "exerquiz" nil)
("ImplMulti" "dljslib" nil)
))
(async nil)
(subtreep nil)
(visible-only nil)
(body-only nil))
(setq counter 0)
(defun ox-mrkup-filter-src-block (text back-end info)
(setq counter (+ counter 1))
(let ((filename (format "part1-scripts/script-%d.py" counter)))
(with-temp-buffer
(insert (mapconcat 'identity (butlast (cdr (split-string text "\n"
t))) "\n"))
(write-region (point-min) (point-max) filename))
(format "%s
\\LaunchBinary{%s}{Open the python script (%s).}
" text filename filename)))
(let ((org-export-filter-src-block-functions '(ox-mrkup-filter-src-block)))
(org-latex-export-to-latex async subtreep visible-only body-only
'(:with-author t
:with-date t
:with-title t
:with-timestamps t
:with-todo-keywords t
:with-toc nil))))
After building the pdf with pdflatex, I get a link with a red box around it
that I can click on, and on my system it opens the python file in the
python editor I have configured to open the file!
Thanks again!
John
