## Gophercon 2019 talk
|
||||
|
||||
There is a [Gophercon 2019 talk](https://go-talks.appspot.com/github.com/eliasnaur/gophercon-2019-talk/gophercon-2019.slide)
|
||||
about Gio and [Scatter](https://scatter.im).
|
||||
|
||||
## Quickstart
|
||||
## Installation
|
||||
|
||||
Gio is designed to work with very few dependencies. It depends only on the platform libraries for
|
||||
window management, input and GPU drawing.
|
||||
|
||||
For Linux you need Wayland and the wayland, xkbcommon, GLES, EGL development packages. On Fedora 28 and newer,
|
||||
install the dependencies with the command

|

|

$ sudo dnf install wayland-devel libxkbcommon-devel mesa-libGLES-devel mesa-libEGL-devel
|
||||
|
||||
On Ubuntu 18.04 and newer, use
|
||||
|
||||
$ sudo apt install libwayland-dev libxkbcommon-dev libgles2-mesa-dev libegl1-mesa-dev
|
||||
|
||||
Note that Gio does not run with the NVIDIA proprietary driver.
|
||||
|
||||
Xcode is required for macOS, iOS, tvOS.
|
||||
|
||||
For Windows you need the ANGLE drivers for emulating OpenGL ES. You can build ANGLE yourself or use
|
||||
[a prebuilt version](https://drive.google.com/file/d/1k2950mHNtR2iwhweHS1rJ7reChTa3rki/view?usp=sharing).

For Android you need the Android SDK with the NDK installed. Point the ANDROID_HOME to the SDK root

directory. Use the gio tool to build a Gio program for Android:

For Android, iOS, tvOS the `gio` tool can build and package a Gio program for you.

|

To build a Gio program as an .aar package, use -buildmode=archive. For example,
|
||||
|
||||
$ export ANDROID_HOME=...
|
||||
$ go run gioui.org/cmd/gio -target android -buildmode archive gioui.org/apps/gophers
|
||||
|
||||
produces gophers.aar, ready to use in an Android project.
|
||||
|
||||
## iOS/tvOS
|
||||
|
||||
To build a Gio program for iOS or tvOS you need a macOS machine with Xcode installed. The gio
|
||||
tool can produce .ipa files for devices and .app directories for simulators. For a device:
|
||||
The `-appid` flag specifies the iOS bundle id or Android package id. The flag is required
|
||||
for creating signed .ipa files for iOS and tvOS devices, because the bundle id must match an id
|
||||
previously provisioned in Xcode. For example,
|
||||
|
||||
$ go run gioui.org/cmd/gio -target ios -appid <bundle-id> gioui.org/apps/gophers
|
||||
|
||||
where <bundle-id> is a valid bundle identifier previously provisioned in Xcode for your device.
|
||||
|
||||
Use the Window=>Devices and Simulators option on Xcode to install the ipa file to the device.
|
||||
If you have [ideviceinstaller](https://github.com/libimobiledevice/ideviceinstaller) installed,
|
||||
you can install the app directly to your device:
|
||||
|
||||
$ ideviceinstaller -i gophers.ipa
|
||||
|
||||
To run a program on a running simulator, use the -o flag with a .app directory:
|
||||
If you just want to run a program on the iOS simulator, use the `-o` flag to specify a .app
|
||||
directory:
|
||||
|
||||
$ go run gioui.org/cmd/gio/ -o gophers.app -target ios gioui.org/apps/gophers
|
||||
|
||||
Install the app with simctl:
|
||||
Install the app to a running simulator with simctl:
|
||||
|
||||
$ xcrun simctl install booted gophers.app
|
||||
|
||||
Pass the -buildmode=archive flag to the gio tool to produce a framework ready to include in an
|
||||
Xcode project. For example,
|
||||
|
||||
$ go run gioui.org/cmd/gio -target ios -buildmode archive gioui.org/apps/gophers
|
||||
|
||||
outputs Gophers.framework with the demo program built for iOS. For tvOS, use `-target tvos`:
|
||||
|
||||
$ go run gioui.org/cmd/gio -target tvos -buildmode archive gioui.org/apps/gophers
|
||||
|
||||
Building for tvOS requires (the not yet released) Go 1.13.
|
||||
|
||||
## Webassembly/WebGL
|
||||
|
||||
To run a Gio program in a browser with WebAssembly and WebGL support, use the Go webassembly
|
||||
driver and add a `<div id="giowindow">` element to a HTML page. The gio tool can also output
|
||||
a directory ready to view in a browser:
|
||||
To run a Gio program in a compatible browser, the `gio` tool can output a directory ready to
|
||||
serve. With the `goxec` tool you don't even need a web server:
|
||||
|
||||
$ go run gioui.org/cmd/gio -target js gioui.org/apps/gophers
|
||||
$ go get github.com/shurcooL/goexec
|
||||
$ goexec 'http.ListenAndServe(":8080", http.FileServer(http.Dir("gophers")))'
|
||||
|
||||
Open http://localhost:8080 in a browser to run the app.
