[Tex/LaTex] Lineno \internallinenumbers – how to make a line number label within a figure

cross-referencingfloatsline-numbering

This concerns the "lineno" package. The \linelabel directive works within the ordinary linenumbers environment. How to create a line number label within a internallinenumbers environment to be able to reference a line number? I need this to be able to refer to a line in the pseudocode in a figure.

Or, alternatively – is there an environment like figure in which the ordinary linenumbers and \linelabel work?

The package fancyvrb provides a line numbering facility (on p. 15 of its documentation is an example for labeling a line number for reference).

More powerful for displaying code is the listings package, which comes with an extensive documentation. It provides line numbering and labeling; its environments can go into a floating environment.

Figured it out - one should use the \internallinenumbers directive, like this:

\begin{figure}
\begin{alltt}
{\footnotesize{\internallinenumbers
def insert(k, v)
  // ...
}}
\end{alltt}
\end{figure}

[Tex/LaTex] Line numbers reset incorrectly using lineno package

The lineno package does a remarkable job of adding numbers to the text, but there are various ways in which it might get it wrong, not through any real deficiency in the package, but just due to the complexities of how pages are built in TeX.

The pagewise numbering scheme requires the package to write the line numbers first to an .aux file, which it then reads back on a second run to generate the per-page numbers.

I was unable to replicate the behaviour in your document, but I suspect that the likely cause is a section break at the very end of the page on which the numbering began to fail. This kind of problem is solved in the same way that a typical bad page break problem is solved.

rewrite the text so that the section appears earlier in the page or moves to the next page
insert a manual \clearpage to force the section onto the next page

This second option should obviously only be done at the last stages of writing the document.
