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 macOS, 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:

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

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

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

See also Other installation methods

Other dependencies

Please select your operating system:

macOS

On macOS (homebrew)

brew install automake pkg-config python cmake yasm
pip install virtualenv

On macOS (MacPorts)

sudo port install python27 py27-virtualenv cmake yasm

On macOS >= 10.11 (El Capitan), you also have to install OpenSSL

brew install openssl

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

./mach 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

sudo apt install git curl autoconf libx11-dev \
    libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
    gperf g++ build-essential cmake virtualenv python-pip \

    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:

pip install virtualenv

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

  1. 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).

  2. 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.

git clone https://github.com/servo/servo
cd servo
./mach build --dev
./mach run tests/html/about-mozilla.html

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

git clone https://github.com/servo/servo
cd servo
mach.bat build --dev

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

./mach build --release
./mach run --release tests/html/about-mozilla.html

Checking for build errors, without building

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

./mach 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 doesnt produce a binary you can run.

Building for Android target

git clone https://github.com/servo/servo
cd servo

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

./mach build --release --android
./mach 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:

cp servobuild.example .servobuild
# edit .servobuild

Running

Run Servo with the command:

./servo [url] [arguments] # if you run with nightly build
./mach run [url] [arguments] # if you run with mach

# For example
./mach run https://www.google.com

Commandline Arguments

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

Keyboard Shortcuts

  • Ctrl+- zooms out
  • Ctrl+= zooms in
  • Alt+left arrow goes backwards in the history
  • Alt+right arrow goes forwards in the history
  • Esc exits servo

Developing

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