--no-document option is require for TeX output

[yegor256]

Currently, I'm getting this:

$ eo-phi-normalizer rewrite --chain --tex celsius.phi
% Rule set following Nov 2024 revision

\documentclass{article}
\usepackage{eolang}
\begin{document}

\begin{phiquation*}
...
\end{phiquation*}

\end{document}

This is impossible to embed into an existing TeX document. Let's add one more option --no-document, which will produce this:

$ eo-phi-normalizer rewrite --chain --tex --no-document celsius.phi
\begin{phiquation*}
...
\end{phiquation*}

@deemp please, help

[deemp]

\documentclass{article}
\usepackage{eolang}
\begin{document}

...

\end{document}

@yegor256, why do you need these lines? What is the use case for this output?

Can I just not output them when --tex is used?

I believe the documentation on the site is the right place for the hint that it's necessary to use the eolang package with this output.

@deemp with --document (by default) the user gets a full LaTeX document, ready for rendering, while with --do-document the user gets a section for his document, read to be used via \input{}
