This LaTeX package helps you write 𝜑-calculus formulas and
draw [SODG](https://github.com/objectionary/sodg) graphs
for [EO](https://www.eolang.org) programming language.

First, [install it][install]
from [CTAN](https://ctan.org/pkg/eolang)
and then use in the preamble:

```tex
\documentclass{article}
\usepackage{eolang}
\begin{document}
\begin{phiquation}
x -> [
  @ -> foo(5),
  y -> [ L> M_1 ]].
\end{phiquation}
\end{document}
```

Otherwise, you can download [`eolang.sty`][sty] and add to your project.

If you want to contribute yourself, make a fork, then create a branch,
then run `l3build ctan` in the root directory.
It should compile everything without errors. If not, submit an issue and wait.
Otherwise, make your changes and then run `l3build ctan` again. If the build is
still clean, submit a pull request.
