The recent reappearance of my two-month-old posting of the Rnmush script
has prompted a wave of commentary (and a couple of bug reports). Here
is the "current" version of Rnmush, which has the following changes from
the original:
Uses MAILRECORD (thanks to Ze'ev Shtadler <steed@techunix.bitnet>).
Ignores -h all by itself (i.e. when no file name given).
Handles wrapped or multiple To: lines in the -h file.
Handles wrapped To: lines generated by mush.
Actually *does* include the "Prepared file to include:"!!
This script is still Berzerkeleyized, and will need minor mods for SysV.
To use Rnmush to send replies from RN:
setenv MAILPOSTER "Rnmush -h %h" # csh
or
MAILPOSTER="Rnmush -h %h" ; export MAILPOSTER # sh
#! /bin/sh -
# Rnmush -- script to use mush for Rnmail
#
# Based on Larry Wall's Rnmail
#
# syntax: Rnmush -h headerfile [oldart] or
# Rnmush destination-list or just
# Rnmush
#
# This script creates two other scripts:
# 1) sh script, which takes care of merging the rn header file with
# mush's editor temp file and then calls the regular visual editor;
# 2) mush script, fed via "mush -source", which sets up some environment
# and arranges for the first script to be used as the visual editor.
