Islandora Code Club

July 9, 2015

Agenda / Goals

• Using the devel module
• Look at what tuque is doing
• Look at code and look at how it is on the site

Notes

• Islandora Vagrant is tricky because you have to ssh into it's file system
• Islandora Sample Content generator
  • good for spinning up sample objects quickly
• Devel
  • Basic Image and Devel
    • Line 101
      • dpm - devel print message function
        • dpm($object, 'object');
        • use dpm anywhere to see what's going on
      • do you typically need to flush caches when you add a dpm
        • no
      • tuque doesn't spit out useful stuff
        • lots of recursions
      • doing a dpm on $object usually won't do anything
    • dpm on variable
      • can see how to do hooks on specific pages like theme hook on:
        • islandora_basic_image__testing_5
• Use dpm on forms all the time
  • dpm($form)
  • very helpful on crazy forms
• IDE / debuggers recommened:
  • PHP Storm
  • Free if you are an open source developer
  • very good for testing changing server side variables / data
• Devel also helpful for telling you how long things are taking to run on your sever
  • page timer
  • memory usage
• Tuque
  • islandora/tuque
  • object.php
    • calls on all the other files in that directroy
      • dpm($object->label, 'label')
      • dpm($object->models, 'models')
  • abstract means it's in another file
  • content
    • if you have a text datastream, can do stuff with them
  • basic image template file
    • getDatastream($islandora_object->id)); ?>
      • this doesn't work, but somthing like this will
    • just put your dpm in a php file if you are doing in a template file
    • with islandora_dublincore_object may have some things
    • dpm(islandora_object->id)
• General questions
  • other functions devel module does besides dpm
    • ui things
      • Devel allows you to modify varialbes and execute php right on your sight
        • if you know something has a variable but doesn't have a config function, you can do it with php
      • Reinstall modules
        • does all you need with one click
    • devel generate
      • allows you to create dummy drupal content
