[](https://github.com/objectionary/eolang.sty/actions/workflows/l3build.yml) [](https://ctan.org/pkg/eolang) [](https://github.com/objectionary/eolang.sty/blob/master/LICENSE.txt) This LaTeX package helps you write ����-calculus formulas and draw [SODG](https://github.com/objectionary/sodg) graphs for [EO](https://www.eolang.org) programming language. First, [install it](https://en.wikibooks.org/wiki/LaTeX/Installing_Extra_Packages) 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`](https://objectionary.github.io/eolang.sty/eolang.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.
