In conjunction with changes made to "the other repo", we now set: export LANG="C" export LC_CTYPE="C" export LC_NUMERIC="C" export LC_TIME="C" export LC_COLLATE="C" export LC_MONETARY="C" export LC_MESSAGES="C" export LC_PAPER="C" export LC_NAME="C" export LC_ADDRESS="C" export LC_TELEPHONE="C" export LC_MEASUREMENT="C" export LC_IDENTIFICATION="C" export LC_ALL="C" instead of just "$LC_ALL", "$LANG", "$LC_NUMERIC".

|
# This tool is intended to be used as a "output tool" during getopt phases 1 and 3.
|
|
# In particular, lines in the bin/md2html.cfg configuration file of the form:
|
|
#
|
|
# -o
|
|
# bin/subst.year-index.sh
|
|
#
|
|
# will cause tools such as gen-year-index.sh to execute this code.
|
|
#
|
|
# The final arg will be in YYYY form, and will be called from
|
|
# the topdir directory under which the YYYY directory must be found.
|
|
# Tools such as bin/gen-year-index.sh, when run via bin/all-run.sh:
|
|
#
|
|
# bin/all-years.sh -v 1 bin/gen-year-index.sh -v 1
|
|
#
|
|
# will supply the YYYY arg. This may be more easily done via make:
|
|
#
|
|
# make gen_year_index
|
|
#
|
|
# IMPORTANT: Each command line option / argument MUST be printed on a separate line!

# firewall - run only with a bash that is version 5.1.8 or later
|
|
#
|
|
# The "/usr/bin/env bash" command must result in using a bash that
|
|
# is version 5.1.8 or later.
|
|
#
|
|
# We could relax this version and insist on version 4.2 or later. Versions
|
|
# of bash between 4.2 and 5.1.7 might work. However, to be safe, we will require
|
|
# bash version 5.1.8 or later.
|
|
#
|
|
# WHY 5.1.8 and not 4.2? This safely is done because macOS Homebrew bash we
|
|
# often use is "version 5.2.26(1)-release" or later, and the RHEL Linux bash we
|
|
# use often use is "version 5.1.8(1)-release" or later. These versions are what
|
|
# we initially tested. We recommend you either upgrade bash or install a newer
|
|
# version of bash and adjust your $PATH so that "/usr/bin/env bash" finds a bash
|
|
# that is version 5.1.8 or later.
|
|
#
|
|
# NOTE: The macOS shipped, as of 2024 March 15, a version of bash is something like
|
|
# bash "version 3.2.57(1)-release". That macOS shipped version of bash
|
|
# will NOT work. For users of macOS we recommend you install Homebrew,
|
|
# (see https://brew.sh), and then run "brew install bash" which will
|
|
# typically install it into /opt/homebrew/bin/bash, and then arrange your $PATH
|
|
# so that "/usr/bin/env bash" finds "/opt/homebrew/bin" (or whatever the
|
|
# Homebrew bash is).
|
|
#
|
|
# NOTE: And while MacPorts might work, we noticed a number of subtle differences
|
|
# with some of their ported tools to suggest you might be better off
|
|
# with installing Homebrew (see https://brew.sh). No disrespect is intended
|
|
# to the MacPorts team as they do a commendable job. Nevertheless we ran
|
|
# into enough differences with MacPorts environments to suggest you
|
|
# might find a better experience with this tool under Homebrew instead.
