# The Servo Parallel Browser Engine Project
|
||
|
||
[](https://travis-ci.org/servo/servo) [](https://ci.appveyor.com/project/servo/servo/branch/master) [](https://changelog.com/podcast/228)
|
||
|
||
Servo is a prototype web browser engine written in the
|
||
[Rust](https://github.com/rust-lang/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`](CONTRIBUTING.md) and [`HACKING_QUICKSTART.md`](docs/HACKING_QUICKSTART.md)
|
||
for help getting started.
|
||
|
||
Visit the [Servo Project page](https://servo.org/) for news and guides.
|
||
|
||
## Setting up your environment
|
||
|
||
### Rustup.rs
|
||
|
||
Building servo requires [rustup](https://rustup.rs/), 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`](https://win.rustup.rs/)
|
||
then follow the onscreen instructions.
|
||
|
||
To install on other systems, run:
|
||
|
||
```sh
|
||
curl 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:
|
||
|
||
```
|
||
curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain none
|
||
```
|
||
|
||

|
||
|
||
#### macOS
|
||
#### On macOS (homebrew)
|
||
|
||
``` sh
|
||
brew install automake pkg-config python cmake yasm
|
||
pip install virtualenv
|
||
```
|
||
#### On macOS (MacPorts)
|
||
|
||
``` sh
|
||
sudo port install python27 py27-virtualenv cmake yasm
|
||
```
|
||
#### On macOS >= 10.11 (El Capitan), you also have to install OpenSSL
|
||
|
||
``` sh
|
||
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
|
||
|
||
``` sh
|
||
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 \
|
||
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](https://github.com/servo/servo/issues/6158) for a workaround.
|
||
|
||
If `virtualenv` does not exist, try `python-virtualenv`.
|
||
|
||

|
||
sudo pacman -S --needed base-devel git python2 python2-virtualenv python2-pip mesa cmake bzip2 libxmu glu \
|
||
pkg-config ttf-fira-sans harfbuzz ccache

|
||
#### On Gentoo Linux
|
||
|
||
```sh
|
||
sudo emerge net-misc/curl \
|
||
media-libs/freetype media-libs/mesa dev-util/gperf \
|
||
dev-python/virtualenv dev-python/pip dev-libs/openssl \
|
||
x11-libs/libXmu media-libs/glu x11-base/xorg-server \
|
||
media-libs/harfbuzz dev-util/ccache
|
||
```
|
||
#### 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.
|
||
|
||
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](https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15)
|
||
> 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](https://github.com/servo/servo/wiki/Building-for-Android)
|
||
|
||
## 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`](https://github.com/servo/servo/blob/master/rust-toolchain) file.
|
||
|
||
## Building
|
||
|
||
Servo is built with [Cargo](https://crates.io/), 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.
|
||
|
||
``` sh
|
||
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):
|
||
``` cmd
|
||
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:
|
||
|
||
``` sh
|
||
./mach build --release
|
||
./mach 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:
|
||
|
||
```sh
|
||
./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 doesn’t produce a binary you can run.
|
||
|
||
### Building for Android target
|
||
|
||
``` sh
|
||
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:
|
||
|
||
```sh
|
||
./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`.
