I am doing a Makefile which I run regularly by Crontab every day at 0230

crontab -e; 30 2 * * * /bin/thePseudocode

Python-like Pseudocode

directories = ["Cardiology", "Rheumatology", "Surgery"]
for directory in directories
   files = directory.files(); % not sure if such a parameter exists
   files = files.match(.*tex); % trying to get only tex files; not sure if match exists
   summaryFile = "";
   for texFile in files
      summaryFile.add( ...
                textFile.match( (?s)\\begin{question}.*?\\end{question} ) ...
      )
      % Solution based on this thread
      % Problem in writing this Regex in Perl http://unix.stackexchange.com/questions/159307/to-match-only-innermost-environment-by-regex
   end
end

save this `summaryFile` as /Users/Masi/Dropbox/QuestionSummary.tex

where files is the list of all files in the directory, and summaryFile is the file which lists all questions in all tex-files. Those files, I want finally compile by pdflatex and read each morning by pdf-reader.

Example file which locates in the folder Rheumatology

\section{Takayasu arteritis}

\begin{question}
{You get a patient. 
What do you notice first in this patient?}
Absence of peripheral pulse.
\end{question}

\begin{question}
{What was the first Takayasu case?}
Young woman in Asia with red vessels in the eye. 
So special eye diagnosis done. 
Affects eye.
\end{question}


Fever of unknown origin can be used when you do not know what is causing the disease. 

% Show cases in MedScape and ask class. 

Aneurysms. 


\subsection{Treatment}

\begin{question}
{What you should always include in Takayasu treatment? 
What are the symptoms?}
Blood pressure.
Aneurysms which will burst without treatment. 
So blood pressure decreasing drugs like beta blockers along in combination with other drugs.
\end{question}

\begin{question}
{When is the checkup of the Takayasu arteritis?} 
Only once per year. 
You could expect every month like normally in this kind of diseases.
But only once per year.
\end{question}

where the output should be for all files in the folder

\section{Rheumatology}

\begin{question}
{You get a patient.

Makefile

all: 
   pdflatex /Users/Masi/Dropbox/QuestionsSummary.tex /Users/Masi/Dropbox/QuestionsSummary.pdf
   pdflatex /Users/Masi/Dropbox/QuestionsSummary.tex /Users/Masi/Dropbox/QuestionsSummary.pdf % to compile a few times to be successful
pdflatex 
% I am not sure if I should have some error management, since often the pdflatex crashes
% So pdflatex is not probably the right tool to go

How can you such a pseudocode in any tools preferred by you? I like Python but would not make all by it.

  • Please explain your pseudocode in words as well. Presumably, files will be the list of all files in the directory right? What's masterfile.add? Ideally, show us an example of your input files and what you want your script to do to them. Commented Oct 4, 2014 at 20:32
  • @terdon Thank you for your comment! I changed the masterFile's name to summaryFile to be more descriptive. I mean by masterfile.add to add the output of the function to the end of the masterfile. Commented Oct 4, 2014 at 20:41
  • Thanks for the edit. So what would the output of this script look like? I understand that you want to extract all \begin{question}... \end{question} from all .tex files in a given directory and save those in a new file. Is that correct? If you expect the output to be compilable by LaTeX, presumably you also want it to be within \begin{document} and \end{document} tags right? Commented Oct 4, 2014 at 20:44
  • @terdon Yes, you are correct. Yes, of course within begin{document}. I will add those things then last. I edited to body to include the expected output too. Commented Oct 4, 2014 at 20:50

If I understand correctly, you're looking for something like this (in bash):

#!/usr/bin/env bash

## avoid errors if a directory has no *tex files
shopt -s nullglob

directories=("Cardiology" "Rheumatology" "Surgery");

## Change this to set whichever options you want.
printf "%s\n%s\n" "\documentclass{YOURCLASS}" "\begin{document}"

for directory in ${directories[@]}
do
    ## Reset the counter, avoid empty sections.
    c=0;
    for file in "$directory"/*tex
    do
        let c++
        [ "$c" -eq 1 ] && printf "\n%s\n" "\section{$directory}"
        ## Extract the wanted lines
        perl -lne '$a=1 && print "" if /\\begin{question}/; 
                  print if $a==1;
                  $a=0 if /\\end{question}/;' "$file" 
        echo ""
    done
done
echo "\end{document}"

If you run that script from the directory that contains Cardiology etc, it should provide output like this:

  • How can you add the PATH to these directories. Those directories for instance locate at /Users/Masi/Dropbox/. I added a parameter like this path="/Users/Masi/Dropbox/ and for file in "$path/$directory"/*tex. I think something wrong in last line. Commented Oct 5, 2014 at 7:56
  • @masi just write for file in /Users/Masi/Dropbox/"$directory"/*tex. But it should also have worked with the variable. Commented Oct 5, 2014 at 10:47
  • See example output below. Duplicate sections only bug. I think the bug is in this line [ "$c" -eq 1 ] && printf "\n%s\n" "\section{$directory}". Commented Oct 5, 2014 at 11:41

    @Masi yes indeed, sorry, silly mistake on my part. It should work as expected now. Commented Oct 5, 2014 at 15:17
  • 1
    @Masi just save the script as foo.sh, make it executable (chmod 755 foo.sh) and run it redirecting its output: /path/to/foo.sh > /path/to/output.tex. Commented Oct 5, 2014 at 16:06
