examgen
===============================================================================

`examgen` is an exam generator for the LaTeX document class `exam`.  It is 
written using literate programming through [NOWEB][noweb].  The program code is 
Python 3 and the documentation is LaTeX.

[noweb]: https://github.com/nrnrnr/noweb


Installation
===============================================================================

There are two options for "installing" this utility.  Either go to 
[releases][Releases], download the code and put it in your PATH.
Otherwise you can follow the [build instructions](#building) below.

[Releases]: https://github.com/dbosk/examgen/releases

Building
-------------------------------------------------------------------------------

To build the executable file you need [NOWEB][noweb], there is a package on 
most systems.  For the documented source code you also need a LaTeX 
distribution, e.g. [TeXLive][TL].  There are TeXLive packages for most systems.
Finally, to run the program you need [Python 3][py3].  These should also be 
available on most systems.

[TL]: https://www.tug.org/texlive/
[py3]: https://www.python.org/

Once you have the dependencies.  Make sure to first clone the submodules:
```sh
git submodule update --init
```
Then you can build the documentation PDF by
```sh
make examgen.pdf
```
To get the executable code run
```sh
make examgen
```
then run `./examgen -h` to get the usage.  (You can also run `make examgen.py` 
is you prefer to have the .py file-name extension.)  Finally, if you'd like to 
have the `examgen` command available somewhere in your $PATH, then
```
sudo make install
```
will put `examgen` in `/usr/local/bin`.

In summary:
```
$ git clone https://github.com/dbosk/examgen.git
$ cd examgen
$ git submodule update --init
$ make examgen.pdf examgen
$ sudo make install
```


Example usage
===============================================================================

To generate the exams I have an exam directory for the course, in this          
directory I have a Makefile which says something along the lines of:

```Makefile
.PHONY: 2016
2016: exam-160603.pdf exam-160822.pdf exam-161024.pdf

exam-161024.pdf: exam-161024.tex q-161024.tex
exam-160822.pdf: exam-160822.tex q-160822.tex
exam-160603.pdf: exam-160603.tex q-160603.tex

%.pdf: %.tex
	latexmk -pdf $<

MODULE_QUESTION_DBs+=	 ../modules/crypto/questions.tex
MODULE_QUESTION_DBs+=	 ../modules/crypto/slides.tex
EXAM_TAGS+=	           AnalyseNeededCryptoProperties
EXAM_TAGS+=	           DesignSystemsWithCryptoProperties

# Until you cover the desired intended learning outcomes ...

q-160603.tex q-160822.tex q-161024.tex: ${MODULE_QUESTION_DBs}
	examgen -NCEi -d ${MODULE_QUESTION_DBs} -t ${EXAM_TAGS} > $@
```

Each `exam-<date>.tex` file `\input`s the corresponding `q-<date>.tex` in the 
question section.

With the above `Makefile`, whenever it's time to submit the exams for the 2016 
instance of the course, I just run the command `make 2016` in that directory.
That will create questions for each exam.  (I can create the individual sets of 
questions by running `make q-<date>.tex`.)

What actually happens when I run that command is the following:

 - The exam generator will try to find questions in the files 
   `MODULE_QUESTION_DBs` whose tags are subsets of the required tags specified 
   in `EXAM_TAGS`. The exam needs enough questions to cover the required tags 
   (the `-C` option) --- but no tags which are not in the required tags (the 
   `-E` option). To avoid excessively many questions on the exam, we require 
   that each question adds coverage of a non-covered required tag (the `-N` 
   option).

 - The `-i` parameter enables the interactive (or inspirational) mode.  This 
   opens each qualifying question in the user's favourite editor, set by the 
   `EDITOR` environment variable. This allows you to use the exam generator to 
   generate questions for inspiration: you use the questions as starting points 
   when creating new ones. But if a question truly is the perfect question you 
   can always use the question without any modification.

 - The way the questions are tagged is as follows.  Each question is tagged 
   with the intended learning outcomes (ILOs) it covers --- which is what we 
   examine in a course!  The ILOs in the course syllabus represent the *least* 
   a student should be able to do to pass the course.  So we need ILOs for the 
   higher grades too to be able to grade an exam A-F. In the example above: 
   AnalyseNeededCryptoProperties for E and DesignSystemsWithCryptoProperties 
   for A.

For a more automated and systematic way of using `examgen`, see [the chapter on 
exam.mk in the documentation of the 
makefiles](https://github.com/dbosk/makefiles/releases).
