To install Eclipse IMP for the first time:

Note:  Some of the screenshots used in these instructions are out of date in that they stilll refer to IMP as "SAFARI."  The name will be changed to protect the innocent; in the meantime, if you can pretend that SAFARI really means IMP, these instructions should still be good.

  1. From Eclipse, invoke "Help" => "Software Updates" => "Find and Install"
  2. In the dialog that shows up, select "Search for new features to install" and click "Next"
  3. The first page of the "Install" dialog will appear; click on the "New Remote Site" button on the upper right-hand side of the that dialog ...
  4. The "New Update Site" dialog will appear
    1. In the "Name" field type "IMP" (this can be anything you want, it's your name for the update site).
    2. In the "URL" field type "http://eclipse-imp.sourceforge.net/updates/" (note the trailing '/' character; it's significant)
    3. Click "OK"

  5. This will return you to the "Install" dialog, where the IMP site will be added to the list of sites available for searching; be sure that the IMP box is checked and click "Finish"
  6. This will bring up the "Updates--Search Results" page; check the "IMP" checkbox, making sure you're getting the latest version, and click "Next"
  7. On the "Search Results" page, check the "IMP" checkbox, and click "Next"
  8. Click "I accept the terms..." and Click "Next"
  9. Click "Finish"; the dialog will disappear, and the status bar will show progress as the Update Manager queries the update server for all available updates
  10. Click "Install All"
  11. Click "Yes" when asked whether to restart Eclipse (assuming that you are done with updates and ready to begin working with IMP)
The IMP installation includes IDEs for X10 and the LPG grammar specification language, so you should now be able to see syntax highlighting, an outline view, and other IDE features when editing .x10 or .g source files.
