Perl module Email::Address

This module is not installed.

On Ubuntu

sudo apt install libemail-address-perl libemail-mime-perl libemail-sender-perl

Others

cpanm install Email::Address

 perl -MCPAN -e "shell"

AMC and TeXLive «vanilla» (ubuntu et debian)

AMC and TeXLive are not installed

Install TeXLive on line.

wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
tar -xzf install-tl-unx.tar.gz
cd install-tl-20xxxx
sudo ./install-tl

	Note
	Replace xxxx with the digits or type TABULATION.

Select O then L and enter 3 times.
Select R then I.

	Note
	TexLive-full is the setting default. If you don't want all the packages, press C then select your packages then R and finally I.

Install fake packages

sudo apt install equivs --no-install-recommends
mkdir -p /tmp/tl-equivs && cd /tmp/tl-equivs
equivs-control texlive-local

Open the web link and note the version number:
https://www.tug.org/texlive/files/debian-equivs-20xx-ex.txt.

Build the package and install it

wget -O texlive-local http://www.tug.org/texlive/files/debian-equivs-20xx-ex.txt
equivs-build texlive-local
sudo dpkg -i texlive-local_20xx-x_all.deb
sudo apt install -f

Install AMC.

sudo add-apt-repository ppa:alexis.bienvenue/amc-stable && sudo apt-get update
sudo apt-get install auto-multiple-choice && sudo apt-get install msmtp

Create a symbolic link.

sudo ln -s /usr/share/texmf/tex/latex/AMC /usr/local/texlive/texmf-local/tex/latex/AMC
sudo mktexlsr
sudo tlmgr update --self --all

AMC and TeXLive are installed (/usr/local/)

Create a symbolic link.

sudo ln -s /usr/share/texmf/tex/latex/AMC /usr/local/texlive/texmf-local/tex/latex/AMC
sudo mktexlsr

Cut the `DOC-sujet.pdf` file in several files

Preferences → Main → Printing → Printing with method → to files

Preferences → Main → Printing → Extracting method → pdftk / gs (ghostscipt) / qpdf (default) / sejda-console (not installed).

processing chain : 2 pages per sheet (2 A5 on 1 A4)

You may print the DOC-sujet.pdf file on 2 pages per 1 sheet with any pdf reader but AMC will not be able to analyse automatic data capture from scans, you have to “crop” it.

convert pdf scans to pbm images.
```
pdfimages yourfile.pdf foo
```

“Crop” each image into two pages.

mogrify -rotate -90 -crop 50%x100% *.pbm

Note

Noneeded to do after the previous command:

mogrify -rotate +90 -crop 50%x100% *.pbm

all pages will be treated and automatically renamed with ImageMagick.

You can force ImageMagick to apply simultaneous black/white threshold to the image to make box checking easier (here 80%).

mogrify -rotate -90 -crop 50%x100% -threshold 80% *.pbm

Let’s move to the Data capture tab of the graphical interface and select this set of pbm images.

pythontex

From https://project.auto-multiple-choice.net/attachments/450/Wiki_AMC_et_PythonTex.pdf and https://project.auto-multiple-choice.net/projects/auto-multiple-choice/wiki/Calcul_formel_avec_Python_dans_AMC

You need to add a script nammed prePythonTex4AMC and make it executable.

#! /bin/sh
SRC=$1
echo "***** JOBNAME=$AMC_JOBNAME"
echo "***** CMD=$AMC_CMD"
rm -rf ./pythontex-files-*
rm -f $AMC_JOBNAME.pytxcode
$AMC_CMD
echo "***** PYTHON"
python /path/to/file/pythontex.py $AMC_JOBNAME.pytxcode
echo "***** END FILTER"

Note

python3 works too.

python3 /path/to/file/pythontex3.py

Add the following three lines to the beginning of the LaTex file.

%%AMC:preprocess_command=/path/to/file/prePythonTex4AMC
%%AMC:jobspecific=1
%%AMC:latex_engine=pdflatex --shell-escape

	Warning
	Some python modules need to be installed (sympy, pygments)
