1. Decide on the level of integration
   • I decided to use the "very low level" of integration, because that this seems like to be the easiest way to work with CSS.
   • More info: http://css.desy.de/content/e760/e761/index_eng.html^{Image Removed}
2. Check out the CSS source code
   1. Install Mercurial locally
      • Download Mercurial source code from http://mercurial.selenic.com/release/mercurial-1.6.4.tar.gz^{Image Removed}
      • Type "make local" in the top directory
      • Install the MercurialEclipse plugin, too, but don't use it as such (need usage tips from Kay & Co.)
   2. Clone the CSS repository
      • Several available: http://sourceforge.net/apps/trac/cs-studio/wiki/SourceRepository^{Image Removed}
      • Use 'read-only' repository => http://cs-studio.hg.sourceforge.net:8000/hgroot/cs-studio/cs-studio^{Image Removed} (no account/password)
   3. Increase JVM memory for Eclipse
      • Edit eclipse.ini in $ECLIPSE_HOME (1024 MB is what I ended up with)
   4. Import the necessary CSS plugins as Eclipse projects (by trail & error, need clarification from Kay & Co.)
      • The minimum list of plugins to develop with DataBrowser need clarification from Kay & Co.:
        
3. Checkout the HLA source code (from CVS)
4. Create the edu.stanford.slac.save2logbook logbook plugin
   • Copy the HLA Save2Logbook source to this plugin and configure for other plugins to use itcode to edu.stanford.slac.logbook
   • Configure the plugin to be used by other plugins (the Eclipse help is good, plus I simply remembered some of it)
5. Add to the DataBrowser plugin the dependency on edu.stanford.slac.save2logbook logbook
   • Eclipse bug: If plugins panel is empty, start typing the plugin name
6. Implement the new features in DataBrowser and Save2Logbook plugins edu.stanford.slac.logbook plugins
   • Find the class in the DataBrowser that handles buttons (Plot)
   • Create a JFace button; set size, label, and background color; add it to the proper JFace figure
   • Add a JFace ActionListener that generates
   • Add JFace Button, called '-> Logbook...'
   • Add JFace ActionListener to generate an Eclipse (Graphics) image from XYGraph
   • Add a method in Save2Logbook to edu.stanford.slac.logbook that saves an Eclipse image as a JPEG file and creates the logbook XML files as well as directories
   • Call the new edu.stanford.slac.logbook method from the new JFace ActionListener
7. Test the new features save2logbook feature by running DataBrowser as an Eclipse application within Eclipse
8. Create a SLAC DataBrowser product configuration (the Eclipse help is no good; I needed to understand the SNS CSS product configuration)
   • Select CSS Data Browser as the actual application
   • Modify the CSS splash image
9. Export the SLAC DataBrowser product to some a local directory and distribute it from there
10. When launching the SLAC DataBrowser for the first time, configure the EPICS and DataBrowser EPICS preferences with correct SLAC settings

Major To-Dos

• Headless build
• "Workspace in use" issues

How to contribute to CSS

• Level of integration http://css.desy.de/content/e760/e761/index_eng.html^{Image Removed}
• Standards
  • Test-driven (JUnit) http://sourceforge.net/apps/trac/cs-studio/wiki/UnitTests^{Image Removed}
• Procedure http://css.desy.de/content/e760/e761/index_eng.html^{Image Removed}
  • Select the level of integration for your plugin from the list above
  • Use existing interfaces and extension points
  • Add new extension points whenever useful
  • Use Eclipse contributions to integrate your plugin seamlessly with other plugins
  • Use common data types (IData) to exchange data (not only strings) with other plugins
  • Localize strings in your code
  • Decouple local requirements from CSS implementations. Use interfaces to decouple.
  • Test CSS core versions and plugins on several platforms (at least Windows, Linux Mac-OS)
• Code style
