Custom setup hangs if LaTeX package missing

[adamgundry]

I attempted to install via cabal install lhs2tex, which resulted in the install process silently hanging. Digging through the output of cabal install -v and inspecting the logs revealed the issue: the package had built successfully, but the custom setup script was attempting to build the manual, and LaTeX had frozen awaiting user input as I was missing some files from my TeXLive distribution.

The immediate solution to my problem was apt install texlive-science, but ideally the custom setup would not hang forever (e.g. using -interaction=nonstopmode).

This seems to be the call to pdflatex:

lhs2tex/Setup.hs

Line 190 in d84bb2a

let loop = do runDbProgram v (simpleProgram "pdflatex") (withPrograms lbi) ["Guide2.tex"]

So, perhaps, replacing ["Guide2.tex"] with ["Guide2.tex", "-interaction=nonstopmode"] should help.
