Homebrew formula: tools/clang/scripts/update.py is missing

[jpmckinney]

I'm seeing the following error:

build/gyp_pdfium

Updating projects from gyp files...
/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file '../tools/clang/scripts/update.py': [Errno 2] No such file or directory
gyp: Call to 'python ../tools/clang/scripts/update.py --print-revision' returned exit status 2 while in /private/tmp/pdfium20151228-46857-htvxjl/build/all.gyp.

I'm not sure how to get tools/clang/scripts/update.py. Googling didn't turn up any clear fix.

It's missing because a simple git clone of https://pdfium.googlesource.com/pdfium (as in the formula) won't download any files to tools/clang. If you get the depot_tools and run:

mkdir repo
cd repo
gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git
gclient sync
cd pdfium

Then tools/clang/scripts/update.py is written.

See https://github.com/knowtheory/homebrew/pull/1 for a one-line fix.

Thanks @jpmckinney! I've got an automated test build in mind for this, but haven't had time to get anything implemented yet :\

PDFium very much follows the chromium model of development, so they seem to happily rearrange all manner of things in the repo (dependencies, build output layout, internal organization, etc).

It's kind of a bummer because installing the depot tools requires changes to one's env, which is why i've decomposed the deps at a particular point.
