I am using pandoc to process an markdown file that is causing me some issues with regard to in-line code blocks. In some cases I need to be able to have a long string without any punctuation or spaces remain together (not split across lines), and in other cases I have a long string without any spaces, but it does have punctuation, such as a comma (,), where it can be word wrapped. The problem is that I need to be able to detect when a overfull condition is going to occur and allow the string to be word wrapped at the comma (or other character). Here is an MWE (in LaTeX) that exhibits the

documentclass[12pt,]{article}

usepackage{lmodern}

usepackage{mathptmx} % makes Time New Roman the default font

usepackage[T1]{fontenc}

% use microtype if available

IfFileExists{microtype.sty}{%

  usepackage{microtype}

  UseMicrotypeSet[protrusion,expansion]{basicmath} % disable protrusion for tt fonts

}{}

usepackage[margin=1in]{geometry}

  string does not contain any spaces and normally we don't wany to break

  under normal conditions, but when the texttt{textbackslash{}hbox}

  gets overfull by a bunch, texttt{"ab,alpha{[}127.0.0.1:8888{]},beta"}.

end{itemize}

end{document}

I'd like to be able to test if an overfull condition is about to occur and allow the string to be split at any of the commas.
