\begin{verbatim} generates deprecated \tt

brunom commented 8 years ago

The following .lhs

\documentclass{scrbook}
%include lhs2TeX.fmt
\begin{document}
\begin{verbatim}
foo
\end{verbatim}
\end{document}

when processed by

lhs2TeX --poly scratch.lhs -o scratch.tex && pdflatex scratch.tex

generates the warning

Class scrbook Warning: Usage of deprecated font command `\tt'!
(scrbook)              You should note, that in 1994 font command `\tt' has
(scrbook)              been defined for compatiblitiy to Script 2.0 only.
(scrbook)              Now, after two decades of LaTeX2e and NFSS2, you
(scrbook)              shouldn't use such commands any longer and within
(scrbook)              KOMA-Script usage of `\tt' is definitely deprecated.
(scrbook)              See `fntguide.pdf' for more information about
(scrbook)              recommended font commands.
(scrbook)              Note also, that KOMA-Script will remove the definition
(scrbook)              of `\tt' anytime until release of about version 3.20.
(scrbook)              But for now, KOMA-Script will replace deprecated `\tt'
(scrbook)              by `\normalfont \ttfamily ' on input line 97.

True. These deprecation warnings exist for a long time, and in principle, I agree. I've just been admittedly too lazy to sort it out myself and make sure everything keeps working, because tt mode is not a mode of lhs2TeX that I use very often.

I'd be happy to accept a patch for this.

After upgrading from texlive2015 to texlive2016, the warning became an error.

Probably fixed by #45?

kosmikus commented 7 years ago

Should be fixed in master and 1.20.
