Here we have the script (edi_webrick.rb) to +do that. The Translator will be called on both inbound and outbound EDI messages, +translating to JSON (JEDI) for edi_fetcher.pl and to EDI for edi_pusher.pl, +respectively. + +Files: + edi_webrick.bash - wrapper script for setting ENV, calling edi_webrick.rb + edi_webrick.cnf - edi_webrick.rb config script + edi_webrick.rb - the main EDI translator daemon script + install.sh - dependency installer (for debian lenny) + README - this file + +This service can be run on a local or remote system that has the proper ruby environment +established. See the install.sh script for an example of how to install the needed ruby +components (on debian lenny linux). + +There is no such thing (yet?) as "push" from a vendor of their EDI responses. Basically +they just put responses in an FTP directory somewhere that you are expected to check. It +would be cool if there were a better way to do that like consuming some RSS feed or +remote API callbacks. + +Evergreen will only support one delivery address per PO. That limitation is based +on the mapping to the delivery address via the ordering_agency org_unit. If items +need to be shipped someplace else, then they need a different PO, for now at least. + +If we want to support multiple vendor profiles, then we drop the unique constraint +on SAN, add a new one on SAN + profile_code. Profile code then goes in the template. +The template logic could get rather complex to support all the optional data elements. + +mbklein says: +'order' mapper won't work for EDIFACT versions later than D.96A, because of a change +to the structure of the BGM segment. But as long as all the supported vendors will +accept a D.96A ORDERS (which I think they do), that's not a problem. + diff --git a/Open-ILS/src/edi_translator/edi_webrick.bash b/Open-ILS/src/edi_translator/edi_webrick.bash new file mode 100755 index 000000000..732d50a0e --- /dev/null +++ b/Open-ILS/src/edi_translator/edi_webrick.bash @@ -0,0 +1,23 @@ +#!/bin/bash +# +# A wrapper for the ruby-script + + +function die_msg { + echo $1; + exit 1; +} + +lib='./acq_edi/lib'; +script='./edi_webrick.rb'; + +[ -r "$script" ] || die_msg "Cannot read script at $script"; +#[ -d "$lib" ] || die_msg "Cannot find lib at $lib"; +# This doesn't work? +# export RUBYLIB=$lib + +# This is necessary +echo export RUBYOPT=rubygems + export RUBYOPT=rubygems +echo ruby $script '&' + ruby $script & diff --git a/Open-ILS/src/edi_translator/edi_webrick.cnf b/Open-ILS/src/edi_translator/edi_webrick.cnf new file mode 100644 index 000000000..6b97c1a72 --- /dev/null +++ b/Open-ILS/src/edi_translator/edi_webrick.cnf @@ -0,0 +1,3 @@ +host = localhost +port = 9191 +file = true diff --git a/Open-ILS/src/edi_translator/edi_webrick.rb b/Open-ILS/src/edi_translator/edi_webrick.rb new file mode 100755 index 000000000..b1386a397 --- /dev/null +++ b/Open-ILS/src/edi_translator/edi_webrick.rb @@ -0,0 +1,112 @@ +#!/usr/bin/env ruby + +require 'rubygems' +require 'optparse' +require 'parseconfig' +require 'stringio' +require 'webrick' +require 'xmlrpc/server' + +require 'openils/mapper' +require 'edi/edi2json' +# require 'edi/mapper' + +base = File.basename($0, '.rb') + +# Defaults +defaults = { + 'port' => 9191, + 'config' => "./#{base}.cnf", + 'namespace' => "/EDI", +# 'defcon' => 0, # uncomment the 2 decons here, and one in the config file to see the collision/interaction +} + +options = { +# 'defcon' => 3, +} + +# Parse command line to override defaults + +OptionParser.new do |opts| + opts.banner = "Usage: #{$0} [options]" + + opts.on("-c", "--config [/path/to/file]", "Config file (default: #{defaults['config']})" ) do |x| + options['config'] = x + end + + opts.on("-n", "--namespace [/web/path]", "Web request namespace (default: #{defaults['namespace']})") do |x| + options['namespace'] = x + end + + opts.on("-p", "--port [PORT]", "Port number (default: #{defaults['port']})" ) do |x| + options['port'] = x + end + + opts.on("-v", "--[no-]verbose", "Set verbosity") do |x| + options['verbose'] = x + end + + opts.on("-d", "--defaults", "Show defaults") do |x| + puts "## Default values:" + defaults.each { |key, value| printf "%10s = %s\n", key, value } + exit + end + + opts.on("-D", "--dumpconfig", "Show effective settings from command-line, config file or defaults") do |x| + options['dumpconfig'] = x + end + + opts.on_tail("-h", "--help", "Show this message") do + puts opts + exit + end + +end.parse! + +if options['verbose'] + puts "OPTIONS: " ; p options + puts "Reading config file #{options['config'] || defaults['config']}" + # puts "\n ARGV: " ; p ARGV +end + +# Read config file, then integrate +c = ParseConfig.new(options['config'] || defaults['config']) +# puts c.methods().sort ; print "\n\n" + +keylist = ["host", "port", "config", "namespace", "verbose"] | c.get_params() | defaults.keys | options.keys + +for key in keylist + src = options.has_key?(key) ?
