Now you can compile your program using the CRTBNDRPG command (or option 14 inPDM):CRTBNDRPG PGM(PDFLIB/HELLO) SRCFILE(PDFLIB/QRPGLESRC) SRCMBR(*PGM) DFTACTGRP(*NO)BNDDIR(PDFLIB/PDFLIB)Error Handling in RPG. PDFlib clients written in ILE-RPG can use the monitor/on-error/endmon error handling mechanism that ILE-RPG provides. Another way to monitor forexceptions is to use the *PSSR global error handling subroutine in ILE-RPG. If an exceptionoccurs, the job log shows the error number, the function that failed and the reasonfor the exception. PDFlib sends an escape message to the calling program.c eval p=PDF_new*c monitor*c eval doc=PDF_begin_document(p:%ucs2(’/tmp/my.pdf’):docoptlist)::* Error Handlingc on-error* Do something with this error* don’t forget to free the PDFlib objectc callp PDF_delete(p)c endmon42 Chapter 2: PDFlib Language Bindings
2.12 Ruby BindingInstalling the PDFlib Ruby Edition. The Ruby 1 extension mechanism works by loadinga shared library at runtime. For the PDFlib binding to work, the Ruby interpreter musthave access to the PDFlib extension library for Ruby. This library (on Windows/Linux/Unix: PDFlib.so; on Mac OS X: PDFlib.bundle) will usually be installed in the site_rubybranch of the local ruby installation directory, i.e. in a directory with a name similar tothe following:/usr/local/lib/ruby/site_ruby//However, Ruby will search other directories for extensions as well. In order to retrieve alist of these directories you can use the following ruby call:ruby -e "puts $:"This list will usually include the current directory, so for testing purposes you can simplyplace the PDFlib extension library and the scripts in the same directory.Error Handling in Ruby. The Ruby binding installs a special error handler which translatesPDFlib exceptions to native Ruby exceptions. The Ruby exceptions can be dealtwith by the usual rescue technique:begin...some PDFlib instructions...rescue PDFlibException => peprint "PDFlib exception occurred in hello sample:\n"print "[" + pe.get_errnum.to_s + "] " + pe.get_apiname + ": " + pe.get_errmsg + "\n"Ruby on Rails. Ruby on Rails 2 is an open-source framework which facilitates Web developmentwith Ruby. The PDFlib extension for Ruby can be used with Ruby on Rails;examples are included in the package. Follow these steps to run the PDFlib examples forRuby on Rails:> Install Ruby.> Install Ruby on Rails.> Unpack the PDFlib package for Ruby which contains samples for Ruby on Rails.> Change to the bind/ruby/RubyOnRails directory and start the Ruby web server:ruby script/server> Point your browser to http://localhost:3000.The code for the PDFlib samples can be found in app/controllers/pdflib_controller.rb.Local PDFlib installation. If you want to use PDFlib only with Ruby on Rails, but cannotinstall it globally for general use with Ruby, you can install PDFlib locally in the vendorsdirectory within the Rails tree. This is particularly useful if you do not have permissionto install Ruby extensions for general use, but want to work with PDFlib in Rails nevertheless.1. See www.ruby-lang.org/en2.
