Tools for scala developers. I have a lot more but it is going to take me some time to organize everything.

Add lines like these to your .profile or similar:

export SCALA_SRC_HOME=/path/to/repo  # path to a scratch checkout of trunk
export SCALA_PACKS_DIR=/path/to/dir  # path to somewhere to cached downloaded builds
source /path/to/libscala.sh

Run this one time:

./git-java/install.sh

If you're lucky, that's it. Examples of available things:

gh-commit <sha|svn>        # accepts sha-1 or rev, shows in browser.  Tab-completion on svn revs!
java -XX:                  # tab-completion on java -XX: options (a tad verbose at the moment)
scala -J-XX:               # also completes on -J-XX: options
gco <tab>                  # a git checkout which completes on local branches only
gh-find Global             # open a browser to those files in trunk matching Global
gh-pull 666                # browse pull request #666
jira-issue 1234            # browse SI-1234 on everyone's favourite tracker
jira-search reporter=bob \
  and fixVersion=\'2.9.2\' # execute JQL search
jira-text-search kaboom    # search summary, comments, and description for keywords
gh-new-pull-request 2.10.x # open the New Pull Request form in github

There are a number of git-XXX wrappers in ~/bin, e.g.

git-diff-grep b1 b2 Bippy         # Show a diff between b1 and b2 - but only the hunks containing "Bippy"
git-log-branch $mergehash         # Git log of the feature branch merged in $mergehash
git-cherry-pick-branch $mergehash # Create a branch backport/$pullid with a squashed commit
                                  # of the commits shown by `git-log-branch`.

You can also install bash completion for all your aliases by adding the following to your .profile. (Warning: it does slow down your login time a touch.)

source $libscalaBash/complete-alias

% gco --a
--all      --amend    --author=

If you have a lot of git branches tied to a non-canonical version of the scala repository, you might want to look at git-remaster, which can fix that all up for you.

There is an sbt project in github-api which provides the basis for "pullreqs", a command you can run from (any project's) github clone to see something like this:

% pullreqs

The git-java part enables you to check jars and *.class files into a git repository and see a useful diff. After you run ./git-java/install.sh, it will tell you to run git-java/demo.sh. Do so. You should see this:
