Introduction

------------



CEF2go is an open source project founded by [Czarek Tomczak](https://www.linkedin.com/in/czarektomczak/)

in 2014 to provide Go bindings for the [Chromium Embedded Framework](https://bitbucket.org/chromiumembedded/cef) (CEF).

CEF2go can act as a GUI toolkit, allowing you to create an HTML 5

based GUI in your application. Or you can provide browser

capabilities to your application.



Currently the CEF2go example creates just a simple window with

the Chromium browser embedded. You can set a few options for

your application like the cache directory. More advanced bindings

are in plans, and that includes javascript bindings and callbacks, so

that you can have bidirectional communication between Go and

Javascript in a native way. Though, it is already possible to

communicate with Go from Javascript, see the "Communication 

between Go and Javascript" section further down this page.



CEF2go is licensed under the BSD 3-clause license, see the LICENSE

file.



Compatibility

-------------

Supported platforms: Windows, Linux, Mac OSX.



CEF2go was tested and works fine with Go 1.2 / Go 1.3.3.



Binary examples

---------------

The binary examples provided here use CEF 3 branch 1750 (Chrome 33

beta channel as of build time).



Windows example: [releases/tag/v0.10](https://github.com/CzarekTomczak/cef2go/releases/tag/v0.10)  



Linux example: [releases/tag/v0.11](https://github.com/CzarekTomczak/cef2go/releases/tag/v0.11)  



Mac OSX example: [releases/tag/v0.12](https://github.com/CzarekTomczak/cef2go/releases/tag/v0.12)

Forks worth a look

------------------

 * [fromkeith/cef2go](https://github.com/fromkeith/cef2go)

    * Adds support for client handlers (eg. Display, LifeSpan, Request,

    Resource, Scheme, Download).

    * Exposes new objects (eg. Browser, Frame, Request, Response). 

    * Tested only on Windows.

 * [paperlesspost/cef2go](https://github.com/paperlesspost/cef2go)

    * Adds suport for a few client handlers including Render handler

    (off-screen rendering to a raw pixel buffer). 

    * Implements V8 callbacks for native communication from Javascript

    to Go.

    * Tested only on Linux.



Communication between Go and Javascript

---------------------------------------

For now to make communication between Go and javascript possible

you have to run an internal http server and communicate using 

XMLHttpRequests in javascript. See the [http_server_windows.go](https://github.com/CzarekTomczak/cef2go/blob/master/src/http_server_windows.go)

example that embeds both a http server and a Chromium browser

in a standalone application. To run it type "build.bat http_server". 

The http server is listening at 127.0.0.1:54007, thus it is not 

accessible from the outside, it can be accessed only from the 

machine it is running on.



Getting started on Windows

--------------------------

1. Install Go 32-bit. CEF 64-bit binaries are still experimental and

   were not tested.



2. Install mingw 32-bit and add C:\MinGW\bin to PATH. You can install mingw

   using [mingw-get-setup.exe](http://sourceforge.net/projects/mingw/files/Installer/).

   Select packages to install: "mingw-developer-toolkit",

   "mingw32-base", "msys-base". CEF2go was tested and works fine

   with GCC 4.8.2. You can check gcc version with "gcc --version".



3. Download CEF 3 branch 1750 revision 1590 binaries:

   [cef_binary_3.1750.1590_windows32.7z](https://github.com/CzarekTomczak/cef2go/releases/download/cef3-b1750-r1590/cef_binary_3.1750.1590_windows32.7z)  

   Copy Release/* to cef2go/Release  

   Copy Resources/* to cef2go/Release  



4. Run build.bat (or "build.bat noconsole" to get rid of the console

    window when running the final executable)



Getting started on Linux

------------------------

1. These instructions work fine with Ubuntu 12.04 64-bit. 

   On Ubuntu 13/14 libudev.so.0 is missing and it is required to 

   create a symbolic link to libudev.so.1. For example on 

   Ubuntu 14.04 64-bit run this command: 

  `cd /lib/x86_64-linux-gnu/ && sudo ln -sf libudev.so.1 libudev.so.0`.



2. Install CEF dependencies:  

   `sudo apt-get install build-essential libgtk2.0-dev libgtkglext1-dev`



3. Download CEF 3 branch 1750 revision 1604 binaries:

   [cef_binary_notcmalloc_3.1750.1604_linux64.zip](https://github.com/CzarekTomczak/cef2go/releases/download/cef3-b1750-r1604/cef_binary_notcmalloc_3.1750.1604_linux64.zip)  

   Copy Release/* to cef2go/Release



4. Run "make" command.



Getting started on Mac OS X

---------------------------

1. These instructions work fine with OS X 10.8 Mountain Lion.

   May also work with other versions, but were not tested.



2. Install Go 32-bit. Tested with Go 1.2-386 for OSX 10.8.

   CEF binaries for OSX 64-bit are still experimental, that's

   why we're using 32-bit. Though you can try building with

   CEF 64-bit, download binaries from [cefbuilds.com](http://cefbuilds.com).



3. Install command line tools (make is required) from:  

   https://developer.apple.com/downloads/  

   (In my case command line tools for Mountain Lion from September 2013)



4. Install XCode (gcc that comes with XCode is required). 

   Use the link above. In my case it was XCode 4.6.3 from June 2013.



5. Download CEF 3 branch 1750 revision 1625 binaries for 32-bit:

   [releases/tag/v0.12](https://github.com/CzarekTomczak/cef2go/releases/tag/v0.12)  

   Copy the cef2go.app directory to cef2go/Release.



6. Run "make" command.



Built a cool app?

-----------------

Built a cool app using CEF2go and would like to share info with

the community? Talk about it on the [CEF2go Forum](http://groups.google.com/group/cef2go).



Familiar with Python or PHP?

----------------------------

The author of CEF2go is also working on CEF bindings

for other languages. For Python see the [CEF Python](https://code.google.com/p/cefpython/) project. For PHP see the 

[PHP Desktop](https://code.google.com/p/phpdesktop/) project.
