Was wondering why R help in recent Fedora only provided --More-- prompt for viewing, rather than allowing arrow key navigation as on RHEL. It turns out it uses a system command for paging and the current default pager is more: grep PAGER /usr/lib64/R/etc/Renviron PAGER=${PAGER-'/usr/bin/more'}
rpm -qf /usr/lib64/R/etc/Renviron R-core-4.4.1-3.fc41.x86_64 This primarily affects function help, where less is much more capable for navigation and searching. Back in 2011 there was some discussion on this list, it it seems the intention is the default should be less: https://stat.ethz.ch/pipermail/r-sig-fedora/2011-August/000194.html I hadn't noticed an issue until recently upgrading to fc41 testing, however it appears to be the case in FC39 and EL9, while the EL8 package is still less: For R-core-4.3.3-2.fc39.x86_64: PAGER=${PAGER-'/usr/bin/more'} R-core-4.4.1-3.el9.x86_64: PAGER=${PAGER-'/usr/bin/more'} R-core-4.4.1-3.el8.x86_64 PAGER=${PAGER-'/usr/bin/less'} configure for R still prefers less if available: $ grep "ac_prog.*PAGER" /tmp/R-4.4.1-3.fc41.src/R-4.4.1/configure for ac_prog in ${PAGER} less more page pg I suspect this was fixed (certainly don't remember it from Fedora <39, but I'd have to hunt down packages to check) and has regressed relatively recently. -- imalone _______________________________________________ R-SIG-Fedora mailing list R-SIG-Fedora@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-fedora
