bors-servo c67669fe73 auto merge of #1349 : dhedlund/servo/issue_222, r=jdm,me 
Fixes #222.

Implements 'text-align' inheritance for inline elements.  The text alignment code has been changed a couple of times since the ticket was originally opened and was improved to inherit the text-align property from from an ancestor element.  This addressed the issue, so long as no inline elements had a text-align property defined.  Both Firefox and Chromium ignore any text-align properties attached to inline elements, but none of the specs are explicit about ignoring the property or inheriting only from non-inline elements:
http://www.w3.org/TR/CSS2/visuren.html#inline-formatting
http://www.w3.org/TR/CSS2/text.html#propdef-text-align

This is my first stab at writing any code that touches the DOM node tree.  Based on a few observations, I made the assumption that the `self.base.node` of a InlineFlow always corresponds to a BlockFlow-based node, no matter how deep inline DOM elements are nested; there was no obvious way to traverse Flow-traited objects directly and I'm not sure if it's possible to get from a FlowData struct back to a non-child {Block,Inline}Flow (probably intentionally).

I could've kept traversing the node tree directly, checking against each node style to ensure it didn't have an inline display property, but I could not create a scenario where the `base.node` was ever an inline.  It also feels like a code smell to be walking up the tree at all, especially for stylesheet properties.  Feels like it should eventually be handled in style::properties directly as being conditional inherited?

README.md

The Servo Parallel Browser Project

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64bit OS X and 64bit Linux.

Servo welcomes contribution from everyone. See CONTRIBUTING.md for help getting started.

Prerequisites

On OS X (homebrew):

brew install https://raw.github.com/Homebrew/homebrew-versions/master/autoconf213.rb
brew install automake libtool pkg-config

On OS X (MacPorts):

sudo port install autoconf213

On Debian-based Linuxes:

sudo apt-get install autoconf2.13 curl freeglut3-dev libtool \
    libfreetype6-dev libfontconfig1-dev libgl1-mesa-dri libglib2.0-dev \
    xorg-dev msttcorefonts

On Debian-based Linuxes (cross-compilation for Android):

sudo apt-get install autoconf2.13 curl libtool ia32-libs

And it needs pre-installed Android tools. See wiki for details

Servo builds its own copy of Rust, so there is no need to provide a Rust compiler.

Building

Servo cannot be built in-tree; you must create a directory in which to run configure and make and place the build artifacts.

git clone https://github.com/mozilla/servo.git
cd servo
mkdir -p build && cd build
../configure
make && make check
./servo ../src/test/html/about-mozilla.html

###Building for Android target

git clone https://github.com/mozilla/servo.git
cd servo
mkdir -p build && cd build
../configure --target-triples=arm-linux-androideabi --android-cross-path=<Android toolchain path> --android-ndk-path=<Android NDK path> --android-sdk-path=<Android SDK path>
make

Running

Commandline Arguments

  • -p INTERVAL turns on the profiler and dumps info to the console every INTERVAL seconds
  • -s SIZE sets the tile size for rendering; defaults to 512
  • -z disables all graphical output; useful for running JS / layout tests

Keyboard Shortcuts

  • Ctrl-L opens a dialog to browse to a new URL (Mac only currently)
  • Ctrl-- zooms out
  • Ctrl-= zooms in
  • Backspace goes backwards in the history
  • Shift-Backspace goes forwards in the history
  • Esc exits servo

Developing

There are lots of make targets you can use:

  • make clean - cleans Servo and its dependencies, but not Rust
  • make clean-rust - cleans Rust
  • make clean-servo - only cleans Servo itself (code in src/components
  • make clean-DEP - cleans the dependency DEP. e.g. make clean-rust-opengles
  • make bindings - generate the Rust WebIDL bindings
  • make DEP - builds only the specified dependency. e.g. make rust-opengles
  • make check-DEP - build and run tests for specified dependency
