The text of the question was being erased by the text of the answers. 9 | - Make the feedback(s) appear on the .pdf documents, when provided. Proposed by [@jcerezochem](https://github.com/jcerezochem) in issue #10 10 | - Updates in the documentation. Proposed by [@theresiavr](https://github.com/theresiavr) in issue #13 11 | - v.0.0.25 Solves two bugs for multichoice questions from issue #6, with code from [@Stivanification](https://github.com/Stivanification) 12 | - v.0.0.24 Solves issue #5 13 | - v.0.0.23 Forgot to load some modules. [PR](https://github.com/Guillaume-Garrigos/moodlexport/pull/4) from [@gregnordin](https://github.com/gregnordin) 14 | - v.0.0.22 Add a new feature to insert images. 15 | - v.0.0.21 The parser used to handle `$`'s was wayyy to slow. This is corrected now. 16 | - v.0.0.20 17 | - I realized that depending on Moodle's version, or depending on how the administrator implements it, inline math like `$e^x$` can not be recognized. Moodle's doc [says](https://docs.moodle.org/3x/fr/Utilisation_de_la_notation_TeX) it is not supported. So, now, every inline math `$e^x$` is converted into `\(e^x\)` just before exporting the data into XML. This allows the user to painlessly type latex as usual with `$`'s. 18 | - Now TEX files are generated without spaces or `_` in the filename. Because latexmk wasn't happy when generating pdfs. 19 | - v.0.0.19 20 | - Corrects bug #3 for multichoice questions, allowing now for negative grades for wrong answers. Proposed by [@Stivanification](https://github.com/Stivanification). 21 | - Corrects bug #2 caused by a broken backcompatibility from the TexSoup Module. Now this module requires the exact needed version 22 | -------------------------------------------------------------------------------- /moodlexport/templates/latextomoodle.sty: -------------------------------------------------------------------------------- 1 | %%%% Define a family of environments and comments that we can use to define Moodle answers/questions/categories 2 | 3 | %%%%% ANSWER 4 | \usepackage{ifthen} 5 | \usepackage{wasysym} 6 | \newcommand{\goodanswer}{$\XBox$~} 7 | \newcommand{\badanswer}{$\Box$~} 8 | \newcommand{\answer}[2][]{% 9 | \ifthenelse{\lengthtest{#1 pt > 0.0pt}} 10 | {\leavevmode\newline \noindent \goodanswer #2 \hfill (${#1} \%$)} 11 | {\leavevmode\newline \noindent \badanswer #2 \hfill (${#1} \%$)} 12 | } 13 | 14 | %%%%% CATEGORY 15 | \newenvironment{category}[1][]{ \newpage \section{Catégorie: #1} }{\bigskip} 16 | 17 | \newcommand{\name}[1]{} 18 | \renewcommand{\description}[1]{} 19 | \newcommand{\path}[1]{} 20 | 21 | %%%%% QUESTION 22 | \newenvironment{question}[1][]{\noindent \textbf{Question:}}{\bigskip} 23 | \renewcommand{\title}[1]{\textbf{(#1)}} 24 | \newcommand{\infocorrecteur}[1]{\smallskip ~\\ \noindent \textbf{Solution:} #1 \smallskip} 25 | 26 | %%%%% FEEDBACKS 27 | \newcommand{\generalfeedback}[1]{\smallskip ~\\ \noindent \textbf{General feedback:} #1 \smallskip} 28 | \newcommand{\correctfeedback}[1]{\smallskip ~\\ \noindent \textbf{Correct feedback:} #1 \smallskip} 29 | \newcommand{\partiallycorrectfeedback}[1]{\smallskip ~\\ \noindent \textbf{Partially correct feedback:} #1 \smallskip} 30 | \newcommand{\incorrectfeedback}[1]{\smallskip ~\\ \noindent \textbf{Incorrect feedback:} #1 \smallskip} 31 | 32 | %%%%% Dummy commands 33 | \newcommand{\type}[1]{} 34 | \newcommand{\grade}[1]{} 35 | %\renewcommand{\penalty}[1]{} 36 | \newcommand{\hidden}[1]{} 37 | \newcommand{\idnumber}[1]{} 38 | \newcommand{\responseformat}[1]{} 39 | \newcommand{\responserequired}[1]{} 40 | \newcommand{\responsefieldlines}[1]{} 41 | \newcommand{\attachments}[1]{} 42 | \newcommand{\attachmentsrequired}[1]{} 43 | \newcommand{\responsetemplate}[1]{} 44 | \newcommand{\single}[1]{} 45 | \newcommand{\shuffleanswers}[1]{} 46 | \newcommand{\answernumbering}[1]{} 47 | \newcommand{\shownumcorrect}[1]{} 48 | 49 | 50 | -------------------------------------------------------------------------------- /examples/simple_example.ipynb: -------------------------------------------------------------------------------- 1 | { 2 | "cells": [ 3 | { 4 | "cell_type": "markdown", 5 | "metadata": {}, 6 | "source": [ 7 | "# Simple example" 8 | ] 9 | }, 10 | { 11 | "cell_type": "markdown", 12 | "metadata": {}, 13 | "source": [ 14 | "From Python:" 15 | ] 16 | }, 17 | { 18 | "cell_type": "code", 19 | "execution_count": 1, 20 | "metadata": {}, 21 | "outputs": [], 22 | "source": [ 23 | "from moodlexport import Question" 24 | ] 25 | }, 26 | { 27 | "cell_type": "code", 28 | "execution_count": 2, 29 | "metadata": {}, 30 | "outputs": [], 31 | "source": [ 32 | "question = Question(\"essay\")\n", 33 | "question.text(\"What is the derivative of $f(x) = e^x + 0.5 \\Vert x \\Vert^2$?\")\n", 34 | "question.grade(1.5)\n", 35 | "question.save(\"my first question\")" 36 | ] 37 | }, 38 | { 39 | "cell_type": "markdown", 40 | "metadata": {}, 41 | "source": [ 42 | "From Latex:" 43 | ] 44 | }, 45 | { 46 | "cell_type": "code", 47 | "execution_count": 3, 48 | "metadata": {}, 49 | "outputs": [], 50 | "source": [ 51 | "from moodlexport import latextomoodle" 52 | ] 53 | }, 54 | { 55 | "cell_type": "code", 56 | "execution_count": 4, 57 | "metadata": {}, 58 | "outputs": [], 59 | "source": [ 60 | "latextomoodle('myquestion.tex','my first question')" 61 | ] 62 | }, 63 | { 64 | "cell_type": "code", 65 | "execution_count": null, 66 | "metadata": {}, 67 | "outputs": [], 68 | "source": [] 69 | } 70 | ], 71 | "metadata": { 72 | "kernelspec": { 73 | "display_name": "Python 3", 74 | "language": "python", 75 | "name": "python3" 76 | }, 77 | "language_info": { 78 | "codemirror_mode": { 79 | "name": "ipython", 80 | "version": 3 81 | }, 82 | "file_extension": ".py", 83 | "mimetype": "text/x-python", 84 | "name": "python", 85 | "nbconvert_exporter": "python", 86 | "pygments_lexer": "ipython3", 87 | "version": "3.7.6" 88 | } 89 | }, 90 | "nbformat": 4, 91 | "nbformat_minor": 4 92 | } 93 | -------------------------------------------------------------------------------- /examples/simple_random_question/template.ipynb: -------------------------------------------------------------------------------- 1 | { 2 | "cells": [ 3 | { 4 | "cell_type": "markdown", 5 | "metadata": {}, 6 | "source": [ 7 | "We want to generate questions where we ask the student if a polynomial equation $aX^2 + bX +c = 0$ with integer coefficients has a solution or no." 8 | ] 9 | }, 10 | { 11 | "cell_type": "code", 12 | "execution_count": 1, 13 | "metadata": {}, 14 | "outputs": [], 15 | "source": [ 16 | "from moodlexport import Category, Question\n", 17 | "from sympy.abc import x #

This requires a lot of parameters to tune, but for now let's focus on the essential : what you basically needs is 33 | 34 | 1. The body/text of your question 35 | 2. A list of potential answers 36 | 3. Setting which answer is the good one (see the documentation for more advanced settings like having more than one good answer) 37 | 4. Exporting that to Moodle 38 | 39 | Here is a short overview on how to do that from Pyhton with `moodlexport`. 40 | 41 | | Writing a multichoice question from Python | 42 | | --- | 43 | | | 44 | | | 45 | | | 46 | | From top to bottom: 1) the python code defining our question and producing a .xml file; 2) that question in Moodle after importing the .xml file; 3) a .pdf produced by the Python code, for convenience. You can find the corresponding code [here](examples/simplest_multichoice_question_from_python/template.ipynb) | 47 | 48 | You could equivalently obtain the very same result by typing the question in a Latex file, and using moodlexport to convert it: 49 | 50 | | Writing a multichoice question from Latex | 51 | | --- | 52 | | | 53 | | | 54 | | | 55 | | A latex file defining a question, and then converted to an .xml by Python. You can find the corresponding code [here](examples/simplest_multichoice_question_from_latex/template.ipynb) | 56 | 57 | To write an essay question, the syntax is as simple: 58 | 59 | | Writing an essay question from Python | 60 | | --- | 61 | | | 62 | | | 63 | | | 64 | | From top to bottom: 1) the python code defining our question and producing a .xml file; 2) that question in Moodle after importing the .xml file; 3) a .pdf produced by the Python code, for convenience. You can find the corresponding code [here](examples/simplest_essay_question_from_python/template.ipynb) | 65 | 66 | The interest of writing your questions in Python is that you can easily generate random problems. Suppose for instance that we want a random question where we ask the student if a polynomial equation $aX^2 + bX +c = 0$, with integer coefficients, has a solution or no. 67 | One way to go is to generate a bunch of those questions, and then let Moodle pick one question at random among those during a `test`. Here is one way to do: 68 | 69 | | Generating random questions | 70 | | --- | 71 | | | 72 | | | 73 | | | 74 | | | 75 | | From top to bottom: 1) the python code defining a category containing many variants of a same question, and producing a .xml file; 2) some of these questions appearing in a category in Moodle 3) one such question in Moodle; 4) a sample of the .pdf produced by the Python code. You can find the corresponding code [here](examples/simple_random_question/template.ipynb) | 76 | 77 | 78 | ### Motivation 79 | 80 | The main motivation behind this module is that : 81 | - it is more comfortable to type maths in your day-to-day Latex interface than within Moodle 82 | - it is easier to define mathematical objects (vectors, matrix) in Python than in Moodle 83 | - generating **random problems** is quite intricate in Moodle, because we quickly face issues such as solutions being too complicated for the students (e.g. non integer), or Moodle being unable to handle certain student's answers (how would could Moodle interpret that $x+x$ is the same than $2x$?). This is much simpler to handle in Python. 84 | - it is easier to manipulate locally a Latex or Python file than doing it on the Moodle interface. It also simplifies collaborating projects. 85 | - it is more convenient to store/read questions/answers in pdf files, than using the Moodle 'bank of questions' interface. 86 | 87 | ## Advanced documentation 88 | 89 | To read more about what this module can do, on how the parameters of your question can be set, see the complete documentation [here](doc/documentation.md). 90 | 91 | ## Changelog 92 | 93 | The changelog can be found [here](doc/changelog.md). 94 | 95 | ## Known issues 96 | 97 | - for the latex package, there is issues with `newcommand` and `renewcommand` because for instance the document class `amsart` defines `text` but it is not the case for `article`. 98 | - So far I have a bad time handling breaklines in a text written in python. Using explicit `
` tags should do the job. -------------------------------------------------------------------------------- /doc/documentation.md: -------------------------------------------------------------------------------- 1 | # Documentation 2 | 3 | *Go back to the [main page](../README.md)* 4 | 5 | 6 | Table of contents of this documentation: 7 | - [Main features of this module so far](#Main-features-of-this-module-so-far) 8 | - [Quick start](#Quick-start) 9 | - [Simple examples from Python](#Simple-examples-from-Python) 10 | - [Simple examples from Latex](#Simple-examples-from-Latex) 11 | - [Exporting many questions at once](#Exporting-many-questions-at-once) 12 | - [Advanced documentation](#Advanced-documentation) 13 | - [Main commands from Python](#Main-commands-from-Python) 14 | - [Main commands from Latex](#Main-commands-from-Latex) 15 | - [Miscellaneous](#Miscellaneous) 16 | - [Inserting an image](#Inserting-an-image) 17 | - [Turning variables into Latex](#Turning-variables-into-Latex) 18 | 19 | 20 | 21 | 22 | 23 | ## Main features of this module so far 24 | - Creating a question. The only supported classes of questions are: 25 | - "essay" : the student answers in a white text box. 26 | - "multichoice" : the question comes with at least 2 possible answers. 27 | - All the options available in Moodle are available here (defining a grade, information for the grader, feedback, etc). See more details below. 28 | - Creating a category (family) of questions. 29 | - Supports Unicode within python and latex : éàê ... 30 | - Supports Latex syntax, whether you write from latex or python, in way that Moodle understands. Supports inline latex with `$e^x$`, `\(e^x\)`, and equation with `$$ f(x) = \sum_i x_i^2 $$, \begin{equation*}...\end{equation*}, \begin{cases}` etc 31 | - Supports export to Moodle via a XML MOODLE file, but also to .tex and .pdf files (which allow more easily to see what you are doing) 32 | - Supports inserting images 33 | 34 | ## Quick start 35 | 36 | ### Simple examples from Python: 37 | 38 | 39 | ```python 40 | from moodlexport import Question 41 | 42 | question = Question("essay") 43 | question.text("What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?") 44 | question.grade(1.5) 45 | question.save("my first question") 46 | ``` 47 | 48 | ### Simple examples from Latex 49 | 50 | You can produce the same result as above by defining your question directly in a Latex file. 51 | Suppose for isntance that you have a Latex file `myquestion.tex` containing the following : 52 | 53 | ```latex 54 | \documentclass{amsart} 55 | \usepackage{latextomoodle} 56 | \begin{document} 57 | \begin{question}[essay] 58 | What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$? 59 | \grade{1.5} 60 | \end{question} 61 | \end{document} 62 | ``` 63 | 64 | Then you can convert this `myquestion.tex` file directly into a `readytoexport.xml` file, by using the following Python commands: 65 | 66 | ```python 67 | from moodlexport import latextomoodle 68 | latextomoodle('myquestion.tex','my first question') 69 | ``` 70 | 71 | Note that if you wish to compile the `.tex` file without errors, you will need to place the Latex package `latextomoodle.sty` in the same folder. This package can be found in `moodlexport/templates` 72 | 73 | ### Exporting many questions at once 74 | 75 | If you want to export more than one question, you might want to gather them within a category, which will produce a single file containing all those questions. Here is how to proceed: 76 | 77 | In Python: 78 | 79 | ```python 80 | from moodlexport import Question, Category 81 | 82 | category = Category("My little catgory name") 83 | 84 | question = Question("essay") 85 | question.text("What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$?") 86 | question.grade(1.5) 87 | question.addto(category) 88 | 89 | question = Question("multichoice") 90 | question.text("Is every symmetric matrix invertible?") 91 | question.grade(2.0) 92 | question.answer("Yes", False) 93 | question.answer("No", True) 94 | question.addto(category) 95 | 96 | category.save() 97 | ``` 98 | In Latex, followed by the python command `latextomoodle('file_name.tex')` : 99 | 100 | ```latex 101 | \documentclass{amsart} 102 | \usepackage{latextomoodle} 103 | \begin{document} 104 | \begin{category}[My little catgory name] 105 | \begin{question}[essay] 106 | What is the derivative of $f(x) = e^x + 0.5 \Vert x \Vert^2$? 107 | \grade{1.5} 108 | \end{question} 109 | \begin{question}[multichoice] 110 | Is every symmetric matrix invertible? 111 | \answer[0]{Yes} 112 | \answer[100]{No} 113 | \grade{2.0} 114 | \end{question} 115 | \end{category} 116 | \end{document} 117 | ``` 118 | 119 | ## Advanced documentation 120 | 121 | ### Main commands from Python 122 | 123 | #### The Category Class 124 | 125 | `category = Category(string)` creates an object of class Category. `string` here specifies the name of the category, which will appear in Moodle. It comes with a few methods: 126 | 127 | - `category.savexml(string)` creates an XML file under the XML Moodle format, ready to import within Moodle. The name of the file is the name of the category by default. If a `string` is given, the name of the file will be `string.xml`. 128 | - `category.savetex(string)` creates a TEX file, containing all the questions of the category, nicely displayed. The name of the file is the name of the category by default (spaces and underscores will be replaced with `-`). If a `string` is given, the name of the file will be `string.tex`. 129 | - `category.savepdf(string)` creates a TEX file as above and then compiles it to generated a PDF file. 130 | - `category.description(string)` Adds a description to the category, which will appear in Moodle. 131 | - `category.path(string)` by default the category is imported at the root of the class. But you might want to order your categories with a tree structure (Moodle allows for subacategories). For instance `category.path("Default/main category/subcategory12/)` will ensure that after import you category will be a subcategory of `subcategory12`. Pay attention to the final `"/"`! 132 | 133 | #### The Question Class 134 | 135 | `question = Question(type)` creates an object of class Question. The `type` of the question can be `essay` (default) or `multichoice`. It comes with a family of methods `question.OPTION(value)` where `OPTION` describes every possible option that you can set in Moodle. The most important ones are: 136 | 137 | - `question.title(string)` sets the title of the question 138 | - `question.text(string)` sets the text (main body) of the question 139 | - `question.grade(float)` sets the grade of the quesiton 140 | - `question.graderinfo(string)` sets the information to be given to the grader 141 | - `question.addto(category)` adds the question to a `category` 142 | 143 | Methods specific to the `essay` type (answer via a text editor): 144 | - `question.responseformat(string)` : 145 | - `editorfilepicker` the student can upload a file as an answer or type in the textbox (default) 146 | - `editor` the student can only use the textbox, upload of a file is unavailable 147 | - `noinline` the textbox is unavailable, upload of a file is mandatory 148 | - `question.responserequired(bool)` : `0` if no response is required (default), `1` if a response is required. 149 | Methods specific to the `essay` type (answer via a text editor): 150 | - `question.responseformat(string)` : `editorfilepicker` lets the student upload a file as an answer (default) , `editor` forbids it, `noinline` gets rid of the text box and forces the student to upload at least a file 151 | - `question.responserequired(bool)` : `0` if no response is required (default), `1` if a response is required. 152 | - `question.attachments(int)`: lets the student upload at most `int` files. 153 | - `question.attachmentsrequired(int)`: student must upload at most `int` files. 154 | 155 | Methods specific to the `multichoice` type (finite number of possible answers): 156 | - `question.answer(string, value)` : Adds a possible answer to the question. `string` is the text of the answer, `value` describes if this answer is correct or no. It can be described in two ways: 157 | - as a boolean `True` or `False` (default) 158 | - as a percentage (integer between 0 and 100), which represents the fraction of the grade attributed to the answer. This is typically used for questions with more than 2 answers. A unique true answer has 100, a wrong answer has 0 (default) 159 | - `question.single(value)` : `true` if only one answer is possible (default), `false` if more than one answer can be selected by the student. 160 | 161 | 162 | 163 | ### Main commands from Latex 164 | 165 | It is possible to use a similar syntax within a TEX document : 166 | 167 | - `\begin{category}[name] ... \end{category}` defines the environment corresponding to a category. It is possible to write various categories within the same document. `name` is the (optional) name of the category. 168 | - `\description{string}` and `\path{string}` are commands working similarly to their python counterpart. 169 | - `\begin{question}[type] ... \end{question}` defines the environment corresponding to a question. It is possible to write various question within the same category. `type` is the type of the question, `essay` by default. 170 | - All the methods mentioned in the Python section can be used in latex. The analogue of `.OPTION(value)` becomes `\OPTION{value}` in Latex (and must be placed within the corresponding environment). For instance : 171 | - `\description{string}` sets the description of a category 172 | - `\grade{float}` sets the grade of a question 173 | - `\answer[value]{string}` adds an answer to a multichoice question 174 | 175 | 176 | The corresponding latex package can be found in `moodlexport/moodlexport/templates`, should be [here](https://github.com/Guillaume-Garrigos/moodlexport/tree/master/moodlexport/templates). 177 | 178 | To convert a .tex file into an .xml, use 179 | 180 | ```python 181 | from moodlexport import latextomoodle 182 | latextomoodle('file_name.tex') 183 | ``` 184 | 185 | You can also import the contents of your .tex file directly into python (you might want to do some modifications before exporting to Moodle). You .tex file must contain one or more categories of questions. To do so, use : 186 | 187 | ```python 188 | from moodlexport import latextopython 189 | # it outputs a list of Category objects, even if you have only one category. 190 | list_of_categories = latextopython('file_name.tex') 191 | ``` 192 | 193 | 194 | 195 | ### Miscellaneous 196 | 197 | #### Inserting an image 198 | 199 | From latex, the command `includegraphics` is supported. More exactly you can use a command like `\includegraphics[width=256px, height=128px]{./some_folder/my_image.png}` from the package `graphicx` 200 | - for the options `width` and `height`, the only supported unit is `px` 201 | - the option `scale` is not supported 202 | - if the command `\includegraphics` is called inline then it will be displayed inline in Moodle as well. 203 | - if the command is called in an environment `\begin{center} ... \end{center}`, the image will be centered as well in Moodle. 204 | - no other environments controlling the position of the image is supported for now. 205 | 206 | From python, the `moodlexport` module provides you with a `includegraphics` function, whose api is as close as possible to the Latex one: 207 | 208 | ```python 209 | from moodlexport import includegraphics 210 | 211 | text = 'here is a cool image:' + includegraphics("./some_folder/my_image.png", width=256, height=128) 212 | 213 | question = Question() 214 | question.text(text) 215 | ``` 216 | 217 | Options of this `includegraphics` python function: 218 | - `width` and `height` (integer). Modify the size of the image, in pixels. If no argument is passed, the image is displayed in its original shape. 219 | - `style` (string). Two possible values: 220 | * `"centered"` (default). The image is displayed in a new line and centered. 221 | * `"inline"`. The image is displayed next to the text. 222 | 223 | #### Turning variables into Latex 224 | 225 | When generating questions from python you will end up with mathematical objects (real number, vector, matrix, etc) that you want to use in your question or answer. This means that at some point you will need to convert those objects into a string, that can eventually be rendered as a Latex expression by Moodle's MathJax feature. 226 | 227 | The function [latexify](https://github.com/Guillaume-Garrigos/latexify) does exactly this for you. Note that it is part of `moodlexport`'s dependencies, so you likely have this module already installed in your environment. -------------------------------------------------------------------------------- /moodlexport/python_to_moodle.py: -------------------------------------------------------------------------------- 1 | 2 | from xml.sax.saxutils import unescape 3 | import copy 4 | import os 5 | import logging 6 | 7 | import xmltodict 8 | import numpy as np # only for np.bool ... too bad :/ 9 | 10 | from moodlexport.string_manager import dict_default_question_moodle, set_oparg 11 | import moodlexport.string_manager as strtools 12 | 13 | #################################### 14 | ## CLASS : CATEGORY 15 | #################################### 16 | 17 | class Category(): 18 | """ 19 | Object collecting Questions under the form of a category, ready to export to Moodle. 20 | Object.dict is a dictionary containing the ifnormation which will be converted into XML 21 | Object.structure is an other dict, which contains the same information, but more (and we don't want 22 | this "more" to appear in the XML.
