1. Check Shindig out.
2. Build it:

mvn clean
mvn

3. Run it:

mvn -Prun

4. Once it runs you should see which port it puts itself on (usually 8080).
5. Browse to http://localhost:8080/gadgets/files/samplecontainer/samplecontainer.html and make sure gadgets work at all.
6. If that all works ok, then check Caja out.
7. Each time you modify Caja, build:

ant jars

8. Copy Caja into Shindig's Maven repository

cp ant-jars/pluginc.jar ~/.m2/repository/caja/caja/r3164/caja-r3164.jar 

9. Rebuild and rerun Shindig:

mvn && mvn -Prun

or, optionally, without tests (much faster, but still slow)

mvn -Dmaven.test.skip=true && mvn -Prun

or, in offline mode (reasonably fast)

mvn -o -Dmaven.test.skip=true && mvn -o -Prun

Just this step is sufficient if all you have changed is Shindig.

1. Shift-reload the gadget container in your browser - a simple reload doesn't always seem to get your updates.
2. It also helps to uncheck "Cache".
3. On the browser, it can be helpful to open the gadget frame in a new tab, add &debug=1 to the URL (before the #) and shift-reload.
4. With luck, you will now be fully equipped for debugging at all levels.

Mercurialising Shindig

Sometimes it might be desirable for several people to work on a checked out version of Shindig to create a patch, rather than just one. Here's how...

• One person creates a Mercurial repo from the appropriate version of Shindig. In order to avoid merging issues with the Subversion files, don't include them in the Mercurial repo. In the Shindig directory

hg init
hg add -X 'glob:**/.svn' -X 'glob:.svn'
hg ci

In the checkin comment, note the Subversion version it was created from. This may come in handy later!

• Other participants clone the Mercurial repo...

hg clone <path to repo> <new directory>

• When any participant has a working change, they first sync with the main repo...

hg pull <path to repo>
hg update

then push their own

hg ci
hg push <path to repo>

Note that there will be no email notifications, so other participants need to be told to do a pull/update.

• To produce the Shindig diff, either the original producer of the repo, who still has a Subversion checkout, can do an update (he won't need to do a pull, because it is his repo that everyone is pushing to) and then carry on in the normal way, or you can check out a fresh copy, pull the Mercurial repo over the top of it, and carry on [TBD].

• Mercurial maintains a record of individual changesets that it has applied and lets you backout the last changeset. This can sometimes be helpful if you have applied a changeset in error and no one has yet submitted another change. First backout the latest change

  hg backout

then apply a new patch and resolve any merge issues

  patch -p0 < yourpatch.patch
  hg merge

Once all merge issues are resolved, test your checkout and if everything looks good, commit and push your changes.
