pandoc2redmine.sh - wrapper script on pandoc to fix textile output for Redmine compatibility

pandoc2redmine.sh

#! /bin/env bash

cat $1 | ruby -pe 'puts " "*20 if $_.match("^```$")' \
  | pandoc -f markdown -t textile \
  | ruby -r CGI -n -e 'print CGI.unescapeHTML($_);' \
  | ruby -ne 'puts $_ unless $_.match(" "*20)' \
  | pbcopy

# without spaces, pandoc outputs "bc." for code blocks, which isn't accepted to redmine
# it also annoyingly HTML escapes its pre- block contents
