Consistent runfile paths across repositories

[jart]

I've written a shell script for the Closure Rules that references runfiles specified in data as follows:

if [[ "${RUNFILES}" == "" ]]; then
  if [[ "$(basename "$(pwd)")" =~ \.runfiles$ ]]; then
    RUNFILES="$(pwd)"
  else
    RUNFILES="${0}.runfiles"
  fi
fi

"${RUNFILES}/third_party/phantomjs/bin/phantomjs" "$@"

The problem is that, when my repository is included by another one, that line will fail unless it looks like the following:

"${RUNFILES}/external/io_bazel_rules_closure/third_party/phantomjs/bin/phantomjs" "$@"

What is the best strategy for dealing with this?

See #848.

The main thing I'm working on now is fixing this, actually. Basically we'll be moving all of the external repositories "down" a couple directories, so your runfiles tree will look like:

bin.runfiles/
    io_bazel_rules_closure/
        WORKSPACE
        some-runfiles
    some_other_repo/
        ...
    another_repo/
        ...

This way, regardless of whether the repo is local or remote, it will be in the same place WRT runfiles.

This is great news @kchodorow. Any estimate on when this will make it into HEAD?

I'm working on it, but it's a huge change. I'm guessing a couple of weeks.
