# TexSurgery

Replaces some commands and environments within a TeX document by evaluating code inside a jupyter kernel.

Much like [sagetex](https://github.com/sagemath/sagetex), but with the following differences:

 1. `sagetex` collects all the code using LaTeX and only then runs `sage` to get the LaTeX output, which definitely works, but this conflicts with some interesting LaTeX packages and is slower than a direct conversion.
 2. `TexSurgery` works in any language with a jupyter kernel

## Installation

    python3 -m pip install texsurgery

## Testing

The following command will perform some common tests, and specific tests for some of the kernels that are installed:

    python3 -m unittest tests

## Selectors

New in version 0.1, `texsurgery` can also gather information using a limited choice of css-style selectors:

~~~~~~~~~~python
>>> from texsurgery.texsurgery import TexSurgery
>>> tex = open('tests/test_find.tex').read()
>>> TexSurgery(tex).findall('question,questionmultx runsilent')
[('questionmultx', [('runsilent', 'a = randint(1,10)\n')]),
 ('question',
   [('runsilent', 'a = randint(2,10)\nf = sin(a*x)\nfd = f.derivative(x)\n')])]
>>> TexSurgery(tex).findall('question,questionmultx choices \correctchoice')
[('question', [('choices', [('\correctchoice', '$\sage{fd}$')])])]
>>> TexSurgery(tex).findall('questionmultx \AMCnumericChoices[_nargs=2]')
[('questionmultx', [('\\AMCnumericChoices',
  ['\\eval{8+a}', 'digits=2,sign=false,scoreexact=3'])]
)]
~~~~~~~~~~


## Example

Start with this LaTeX code:

~~~~~~~~~~latex
% Any jupyter kernel is available
\usepackage[sagemath]{texsurgery}

% Compatible with any other LaTeX package
\usepackage[bloc,completemulti]{automultiplechoice}

% Example of user macros
\providecommand{\abs}[1]{\lvert#1\rvert}
\newcommand{\R}{\mathbb{R}}

% TexSurgery can replace some \commands before pdflatex runs
\begin{minipage}{.85\linewidth}
Student: {\bf \name \;  \surname},  \quad ID:  {\bf \id}
\end{minipage}

\begin{question}{derivative-sin}
\qvariant{1} \qtags{derivative}
% TexSurgery will run code in a jupyter kernel
\begin{runsilent}
set_random_seed(\seed)
a = randint(2,10)
f = sin(a*x)
fd = f.derivative(x)
\end{runsilent}
% TexSurgery will eval code in a jupyter kernel
% and replace \eval{expr} with the output from the kernel
% \sage{expr} is just an alias for \eval{latex(expr)}
What is the first derivative of $\sage{f}$?
\begin{choices}
  \correctchoice{$\sage{fd}$}
  \wrongchoice{$\sage{fd*a}$}
  \wrongchoice{$\sage{fd + a}$}
\end{choices}
\begin{explain}
\begin{run}
# TexSurgery will run code in the jupyter kernel
# and replace this environment with the full output
\end{run}
\end{explain}
\end{question}
~~~~~~~~~~

and run this `python` code:
~~~~~~~~~~python
from texsurgery.texsurgery import TexSurgery
student_vars = dict(name='Fulano', surname='de Tal', seed='1', id='314159')
ts = TexSurgery(tex_source).data_surgery(student_vars).code_surgery()
~~~~~~~~~~

in order to transform it into this:

~~~~~~~~~~latex
% Compatible with any other LaTeX package
\usepackage[bloc,completemulti]{automultiplechoice}

% Example of user macros
\providecommand{\abs}[1]{\lvert#1\rvert}
\newcommand{\R}{\mathbb{R}}

\begin{minipage}{.85\linewidth}
Student: {\bf Fulano \;  de Tal},  \quad ID:  {\bf 314159}
\end{minipage}

\begin{question}{derivative-sin}
\qvariant{1} \qtags{derivative}
What is the first derivative of $\sin\left(7 \, x\right)$?
\begin{choices}
  \correctchoice{$7 \, \cos\left(7 \, x\right)$}
  \wrongchoice{$49 \, \cos\left(7 \, x\right)$}
  \wrongchoice{$7 \, \cos\left(7 \, x\right) + 7$}
\end{choices}
\begin{explain}
\begin{run}
# TexSurgery will run code in the jupyter kernel
# and replace this environment with the full output
\end{run}
\end{explain}
\end{question}
