Feature #13981
closedin configure, detect mandoc and set MANTYPE=doc
Description
My OpenBSD machine uses mandoc
to format manuals. Ruby's configure guesses MANTYPE=doc or MANTYPE=man after looking for nroff
or awf
, but doesn't know mandoc
. I attach a patch to teach configure.ac about mandoc. This patch changes the guess for my machine from MANTYPE=man to MANTYPE=doc; manuals like ri(1) look better when MANTYPE=doc.
I change the code to use AC_PATH_PROGS_FEATURE_CHECK. My intent is that if we find one of [nroff awf mandoc], but it can't do -mdoc, then we check the other commands for -mdoc. The old code would only check the first found command for -mdoc.
Because I no longer use AC_PATH_PROGS, the configure script no longer sets NROFF=$ac_path_NROFF and no longer does AC_SUBST(NROFF). Therefore, we can't use @NROFF@
in Makefile.in or RbConfig.expand('$(NROFF)')
in Ruby scripts. I believe that Ruby doesn't use NROFF in that way, so I don't need to set NROFF in configure.
