[Bug] Fail to wrap some code in the preamble part

[cnkjw]

I have the following code:

\documentclass[10pt,a4paper]{article}
\usepackage[breaklinks,colorlinks,urlcolor=blue,citecolor=blue,linkcolor=blue,bookmarks]{hyperref}
\usepackage{caption}
\DeclareCaptionLabelSeparator{pipe}{~\textbf{\textbar}~}
\captionsetup{font=small,margin=2em,labelfont=bf,labelsep=pipe,figurename=Figure,tablename=Table}

\begin{document}
example example example
\end{document}

I expect the default processing result of the tex-fmt to be as follows:

\documentclass[10pt,a4paper]{article}
\usepackage[breaklinks,colorlinks,urlcolor=blue,citecolor=blue,linkcolor=blue,
            bookmarks]{hyperref}
\usepackage{caption}
\DeclareCaptionLabelSeparator{pipe}{~\textbf{\textbar}~}
\captionsetup{font=small,margin=2em,labelfont=bf,labelsep=pipe,
              figurename=Figure,tablename=Table}

\begin{document}
  example example example
\end{document}

But the actual situation is that tex-fmt gives a warning message:

WARN: tex-fmt test.tex: Line 2 (2). Line cannot be wrapped. \usepackage[breaklinks,colorlinks,urlcolor=blue,citecolor=blue,linkcolor=blue,bookmarks]{hyperref}
WARN: tex-fmt test.tex: Line 5 (5). Line cannot be wrapped. \captionsetup{font=small,margin=2em,labelfont=bf,labelsep=pipe,figurename=Figure,tablename=Table}

Hi @cnkjw, currently tex-fmt doesn't consider commas , to be valid wrapping points, it only searches for spaces.

I see that this could be useful in the preamble, but tex-fmt isn't yet "preamble-aware". I'm working on this for a re-wrapping feature (#64) so maybe I can look into enabling wrapping at commas when in the preamble as part of that.

OK, thank you very much for your timely reply.

For LaTeX code, automatic wrapping may indeed be a challenge. I have found that the wrap feature often fails when using latexindent, so I am currently trying out the great new project, tex-fmt. I look forward to the early realization of this feature.
