I am trying to highlight my revised paper in latex, since when I highlight its PDF using Foxit the highlights are not shown after pressing generate PDF in journal's website.
I have some troubles: I must sometimes highlight citations, so I tried \hl{\cite{c1}} by \usepackage{xcolor}.
Some lines later, I need to highlight some paragraphs. when I tryied \hl{long text}, all the text was written in one line! So I decided to highlight it using \begin{highlight}some long text \end{highlight}
In the next part of the paper, I need just to highlight a sentence starting in the middle of a line up to in the middle of some lines next! I have tried using the soul package, but it wasn't possible beside xcolor package.
What should I do? I have these features in my paper: some citations to be highlighted, some long paragraphs to be highlighted, some sentences starting in the middle of a line (some lines long), and some figures (I know I should use framebox for figures, but I just mentioned it to be sure not any further package for solving previously mentioned parts makes problem with this simultaniously).
(Beside the problems, I even didn't see the shape of \begin{highlight}...\end{highlight} appropriate. Because it adds indentations to the paragraphs and changes the appearance of the paragraph)
\usepackage{lua-ul}? I had the error that Latex cant find it. Then I downloaded it from (https://ctan.org/pkg/lua-ul) but it didn't contain lua-ul.sty. So I found (https://www.tug.org/svn/texlive/trunk/Master/texmf-dist/tex/lualatex/lua-ul/) from (https://github.com/MiKTeX/miktex-packaging/issues/180). But after putting these file beside my manuscript.tex I have the error oflua-ul.lua:73: in main chunk [C]: in function 'require' [\directlua]:1: in main chunk. l.30 \directlua{require'lua-ul'}– m123 Aug 11 '20 at 12:12
