Bopytex is a command line tool for producing random math exercises with their correction. It embeds [mapytex](https://git.opytex.org/lafrite/Mapytex) and [python](python.org) into [latex](latex-project.org) through [jinja](jinja.pocoo.org).
|
|
|
|
## Installing
|
|
|
|
Install and update using [pip](https://pip.pypa.io/en/stable/quickstart/)
|
|
|
|
pip install -U bopytex
|
|
|
|
## Simple example
|
|
|
|
Let's say I want an exercise on adding 2 fractions (files are in `examples`).
|
|
|
|
The *latex* template called `tpl_add_fraction.tex`
|
|
|
|
``` latex
|
|
\documentclass[12pt]{article}
|
|
|
|
\begin{document}
|
|
|
|
\section{Ajouts de fractions}
|
|
|
|
Adding two fractions
|
|
%- set e = Expression.random("{a} / {b} + {c} / {k*b}", ["b > 1", "k>1"])
|
|
\[
|
|
A = \Var{e}
|
|
\]
|
|
Solution
|
|
\[
|
|
\Var{e.simplify().explain() | join('=')}
|
|
\]
|
|
\end{document}
|
|
```
|
|
|
|
Generate latex files and compile those for 2 different subjects.
|
|
|
|
```
|
|
bopytex -t tpl_add_fractions.tex -N 2
|
|
```
|
|
|
|
It produces 2 sources files
|
|
|
|
- `01_add_fractions.tex`
|
|
|
|
```latex
|
|
\documentclass[12pt]{article}
|
|
|
|
\begin{document}
|
|
|
|
\section{Ajouts de fractions}
|
|
|
|
Adding two fractions
|
|
\[
|
|
A = \frac{- 2}{4} + \frac{7}{8}
|
|
\]
|
|
Solution
|
|
\[
|
|
\frac{- 2}{4} + \frac{7}{8}=\frac{- 2 \times 2}{4 \times 2} + \frac{7}{8}=\frac{- 4}{8} + \frac{7}{8}=\frac{- 4 + 7}{8}=\frac{3}{8}
|
|
\]
|
|
|
|
\end{document}
|
|
```
|
|
|
|
- `02_add_fractions.tex`
|
|
|
|
```latex
|
|
\documentclass[12pt]{article}
|
|
|
|
\begin{document}
|
|
|
|
\section{Ajouts de fractions}
|
|
|
|
Adding two fractions
|
|
\[
|
|
A = \frac{8}{9} + \frac{3}{63}
|
|
\]
|
|
Solution
|
|
\[
|
|
\frac{8}{9} + \frac{3}{63}=\frac{8 \times 7}{9 \times 7} + \frac{3}{63}=\frac{56}{63} + \frac{3}{63}=\frac{56 + 3}{63}=\frac{59}{63}
|
|
\]
|
|
|
|
\end{document}
|
|
```
|
|
|
|
And a ready to print pdf.
