The Servo Parallel Browser Engine Project

Linux Build Status Windows Build Status Changelog #228

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

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

Visit the Servo Project page for news and guides.

Setting up your environment
Rustup.rs

Building servo requires rustup, version 1.8.0 or more recent. If you have an older version, run rustup self update.

To install on Windows, download and run rustup-init.exe then follow the onscreen instructions.

To install on other systems, run:

 https://sh.rustup.rs -sSf | sh

This will also download the current stable version of Rust, which Servo won?t use. To skip that step, run instead:

 https://sh.rustup.rs -sSf | sh -s -- --default-toolchain none

See also Other installation methods

Other dependencies

Please select your operating system:

OS X On OS X (homebrew) 
 install automake pkg-config python cmake yasm
install virtualenv
On OS X (MacPorts) 
 port install python27 py27-virtualenv cmake yasm
On OS X >= 10.11 (El Capitan), you also have to install OpenSSL 
 install openssl

rt OPENSSL_INCLUDE_DIR="$(brew --prefix openssl)/include"
rt OPENSSL_LIB_DIR="$(brew --prefix openssl)/lib"

ch build ...

If you've already partially compiled servo but forgot to do this step, run ./mach clean, set the shell variables, and recompile.

On Debian-based Linuxes 
 apt install git curl freeglut3-dev autoconf libx11-dev \
libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
gperf g++ build-essential cmake virtualenv python-pip \
libssl1.0-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev \
libglu1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev libdbus-1-dev \
libharfbuzz-dev ccache

If you using a version prior to Ubuntu 17.04 or Debian Sid, replace libssl1.0-dev with libssl-dev.

If you are on Ubuntu 14.04 and encountered errors on installing these dependencies involving libcheese, see #6158 for a workaround.

If virtualenv does not exist, try python-virtualenv.

On Windows (MSVC)

  1. Install Python for Windows (https://www.python.org/downloads/release/python-2714/). The Windows x86-64 MSI installer is fine. You should change the installation to install the “Add python.exe to Path” feature.

  2. Install virtualenv.

    In a normal Windows Shell (cmd.exe or “Command Prompt” from the start menu), do:

    install virtualenv

    If this does not work, you may need to reboot for the changed PATH settings (by the python installer) to take effect.

  3. Install Git for Windows (https://git-scm.com/download/win). DO allow it to add git.exe to the PATH (default settings for the installer are fine).

  4. Install Visual Studio Community 2017 (https://www.visualstudio.com/vs/community/). You MUST add “Visual C++” to the list of installed components. It is not on by default. Visual Studio 2017 MUST installed to the default location or mach.bat will not find it.

    If you encountered errors with the environment above, do the following for a workaround:

    1. Download and install Build Tools for Visual Studio 2017
    2. Install python2.7 x86-x64 and virtualenv
    3. Run mach.bat build -d.

If you have troubles with x64 type prompt as mach.bat set by default:

  1. you may need to choose and launch the type manually, such as x86_x64 Cross Tools Command Prompt for VS 2017 in the Windows menu.)
  2. cd to/the/path/servo
  3. python mach build -d
Cross-compilation for Android

Pre-installed Android tools are needed. See wiki for details

The Rust compiler

Servo's build system uses rustup.rs to automatically download a Rust compiler. This is a specific version of Rust Nightly determined by the rust-toolchain file.

Building

Servo is built with Cargo, the Rust package manager. We also use Mozilla's Mach tools to orchestrate the build and other tasks.

Normal build

To build Servo in development mode. This is useful for development, but the resulting binary is very slow.

clone https://github.com/servo/servo
ervo
ch build --dev
ch run tests/html/about-mozilla.html

Or on Windows MSVC, in a normal Command Prompt (cmd.exe):

clone https://github.com/servo/servo
ervo
.bat build --dev

For benchmarking, performance testing, or real-world use, add the --release flag to create an optimized build:

ch build --release
ch run --release tests/html/about-mozilla.html
Checking for build errors, without building

If you?re making changes to one crate that cause build errors in another crate, consider this instead of a full build:

ch check

It will run cargo check, which runs the analysis phase of the compiler (and so shows build errors if any) but skips the code generation phase. This can be a lot faster than a full build, though of course it doesn?t produce a binary you can run.

Building for Android target
clone https://github.com/servo/servo
ervo

rt ANDROID_SDK="/path/to/sdk"
rt ANDROID_NDK="/path/to/ndk"
rt ANDROID_TOOLCHAIN="/path/to/toolchain"
rt PATH="$PATH:/path/to/toolchain/bin"

ch build --release --android
ch package --release --android

Rather than setting the ANDROID_* environment variables every time, you can also create a .servobuild file and then edit it to contain the correct paths to the Android SDK/NDK tools:

ervobuild.example .servobuild
it .servobuild
Running

Run Servo with the command:

rvo [url] [arguments] # if you run with nightly build
ch run [url] [arguments] # if you run with mach

r example
ch run https://www.google.com
Commandline Arguments
Keyboard Shortcuts
Developing

There are lots of mach commands you can use. You can list them with ./mach --help.
