in how a GDBusServer (or a GDBusConnection)
authenticates remote peers.
since: 2.26
DBusConnection
The GDBusConnection type is used for D-Bus connections to remote
peers such as a message buses.
since: 2.26
DBusInterfaceSkeleton
Abstract base class for D-Bus interfaces on the service side.
since: 2.30
DBusMenuModel
GDBusMenuModel is an implementation of GMenuModel that can be
used as a proxy for a menu model that is exported over D-Bus with
g_dbus_connection_export_menu_model().
DBusMessage
A type for representing D-Bus messages that can be sent or received
on a GDBusConnection.

DBusObjectManagerClient
GDBusObjectManagerClient is used to create, monitor and delete object
proxies for remote objects exported by a GDBusObjectManagerServer
(or any code implementing the
org.freedesktop.DBus.ObjectManager interface).
since: 2.30
DBusObjectManagerServer
GDBusObjectManagerServer is used to export GDBusObject instances
using the standardized
org.freedesktop.DBus.ObjectManager
interface. For example, remote D-Bus clients can get all objects
and properties in a single call. Additionally, any change in the
object hierarchy is broadcast using signals. This means that D-Bus
clients can keep caches up to date by only listening to D-Bus signals.
since: 2.30
DBusObjectProxy
A GDBusObjectProxy is an object used to represent a remote object
with one or more D-Bus interfaces. Normally, you don’t instantiate
a GDBusObjectProxy yourself — typically GDBusObjectManagerClient
is used to obtain it.
since: 2.30
DBusObjectSkeleton
A GDBusObjectSkeleton instance is essentially a group of D-Bus
interfaces. The set of exported interfaces on the object may be
dynamic and change at runtime.
since: 2.30

interface on a remote object. A GDBusProxy can be constructed for
both well-known and unique names.
since: 2.26
DBusServer
GDBusServer is a helper for listening to and accepting D-Bus
connections. This can be used to create a new D-Bus server, allowing two

A server instance provided in this way will not perform message routing or
implement the
org.freedesktop.DBus interface.
since: 2.26
DebugControllerDBus
GDebugControllerDBus is an implementation of GDebugController
which exposes debug settings as a D-Bus object.
since: 2.72

EmblemedIcon
GEmblemedIcon is an implementation of GIcon that supports
adding an emblem to an icon. Adding multiple emblems to an
icon is ensured via g_emblemed_icon_add_emblem().
FileEnumerator
GFileEnumerator allows you to operate on a set of GFile objects,
returning a GFileInfo structure for each file enumerated (e.g.
g_file_enumerate_children() will return a GFileEnumerator for each
of the children within a directory).
FileIcon
GFileIcon specifies an icon by pointing to an image file
to be used as icon.
FileInfo
Stores information about a file system object referenced by a GFile.
FileInputStream
GFileInputStream provides input streams that take their
content from a file.
FileIOStream
GFileIOStream provides I/O streams that both read and write to the same
file handle.
since: 2.22

kind of filtering operation on a base stream. Typical examples
of filtering operations are character set conversion, compression
and byte order flipping.
FilterOutputStream
Base class for output stream implementations that perform some
kind of filtering operation on a base stream. Typical examples
of filtering operations are character set conversion, compression
and byte order flipping.
InetAddress
GInetAddress represents an IPv4 or IPv6 internet address. Use
g_resolver_lookup_by_name() or
g_resolver_lookup_by_name_async() to look up the GInetAddress for
a hostname. Use g_resolver_lookup_by_address() or
g_resolver_lookup_by_address_async() to look up the hostname for a
GInetAddress.
InetAddressMask
GInetAddressMask represents a range of IPv4 or IPv6 addresses
described by a base address and a length indicating how many bits
of the base address are relevant for matching purposes. These are
often given in string form. For example, 10.0.0.0/8, or fe80::/10.
since: 2.32
InetSocketAddress
An IPv4 or IPv6 socket address. That is, the combination of a
GInetAddress and a port number.
InputStream
GInputStream is a base class for implementing streaming input.
IOModule
Provides an interface and default functions for loading and unloading
modules. This is used internally to make GIO extensible, but can also
be used by others to implement module loading.
IOStream
GIOStream represents an object that has both read and write streams.
Generally the two streams act as separate input and output streams,
but they share some common resources and state. For instance, for
seekable streams, both streams may use the same position.
since: 2.22
ListStore
GListStore is a simple implementation of GListModel that stores
all items in memory.
MemoryInputStream
GMemoryInputStream is a class for using arbitrary
memory chunks as input for GIO streaming input operations.

using the functions below.
since: 2.32
MenuItem
GMenuItem is an opaque structure type. You must access it using the
functions below.
since: 2.32
MenuLinkIter
GMenuLinkIter is an opaque structure type. You must access it using
the functions below.
since: 2.32
MenuModel
GMenuModel represents the contents of a menu — an ordered list of
menu items. The items are associated with actions, which can be
activated through them. Items can be grouped in sections, and may
have submenus associated with them. Both items and sections usually
have some representation data, such as labels or icons. The type of
the associated action (ie whether it is stateful, and what kind of
state it has) can influence the representation of the item.
since: 2.32
MountOperation
GMountOperation provides a mechanism for interacting with the user.
It can be used for authenticating mountable operations, such as loop
mounting files, hard drive partitions or server locations. It can
also be used to ask the user questions or show a list of applications
preventing unmount or eject operations from completing.
NativeSocketAddress
A socket address of some unknown native type.
since: 2.46
NativeVolumeMonitor
NetworkAddress
GNetworkAddress provides an easy way to resolve a hostname and
then attempt to connect to that host, handling the possibility of
multiple IP addresses and multiple address families.
NetworkService
Like GNetworkAddress does with hostnames, GNetworkService
provides an easy way to resolve a SRV record, and then attempt to
connect to one of the hosts that implements that service, handling
service priority/weighting, multiple IP addresses, and multiple
address families.
Notification
GNotification is a mechanism for creating a notification to be shown
to the user — typically as a pop-up notification presented by the
desktop environment shell.
since: 2.40
OutputStream
GOutputStream is a base class for implementing streaming output.
Permission
A GPermission represents the status of the caller’s permission to
perform a certain action.

reflecting and controlling the value of a GObject property.
since: 2.38
ProxyAddress
A GInetSocketAddress representing a connection via a proxy server.
since: 2.26
ProxyAddressEnumerator
GProxyAddressEnumerator is a wrapper around
GSocketAddressEnumerator which takes the GSocketAddress
instances returned by the GSocketAddressEnumerator
and wraps them in GProxyAddress instances, using the given
GProxyAddressEnumerator:proxy-resolver.
Resolver
The object that handles DNS resolution. Use g_resolver_get_default()
to get the default resolver.
Settings
The GSettings class provides a convenient API for storing and retrieving
application settings.
SettingsBackend
The GSettingsBackend interface defines a generic interface for
non-strictly-typed data that is stored in a hierarchy. To implement
an alternative storage backend for GSettings, you need to
implement the GSettingsBackend interface and then make it implement the
extension point G_SETTINGS_BACKEND_EXTENSION_POINT_NAME.
SimpleAction
A GSimpleAction is the obvious simple implementation of the
GAction interface. This is the easiest way to create an action for
purposes of adding it to a GSimpleActionGroup.
SimpleActionGroup
GSimpleActionGroup is a hash table filled with GAction objects,
implementing the GActionGroup and GActionMap
interfaces.
since: 2.28
SimpleAsyncResult
As of GLib 2.46, GSimpleAsyncResult is deprecated in favor of
GTask, which provides a simpler API.
SimpleIOStream
GSimpleIOStream creates a GIOStream from an arbitrary
GInputStream and GOutputStream. This allows any pair of
input and output streams to be used with GIOStream methods.
since: 2.44
SimplePermission
GSimplePermission is a trivial implementation of GPermission
that represents a permission that is either always or never allowed. The
value is given at construction and doesn’t change.
SimpleProxyResolver
GSimpleProxyResolver is a simple GProxyResolver implementation
that handles a single default proxy, multiple URI-scheme-specific
proxies, and a list of hosts that proxies should not be used for.
since: 2.36
Socket
A GSocket is a low-level networking primitive. It is a more or less
direct mapping of the BSD socket API in a portable GObject based API.
It supports both the UNIX socket implementations and winsock2 on Windows.
since: 2.22
SocketAddress
GSocketAddress is the equivalent of
struct sockaddr and its subtypes in the BSD sockets
API. This is an abstract class; use GInetSocketAddress for
internet sockets, or GUnixSocketAddress for UNIX domain sockets.
SocketAddressEnumerator
GSocketAddressEnumerator is an enumerator type for
GSocketAddress instances. It is returned by enumeration functions
such as g_socket_connectable_enumerate(), which returns a
GSocketAddressEnumerator to list each GSocketAddress which could
be used to connect to that GSocketConnectable.
SocketClient
GSocketClient is a lightweight high-level utility class for connecting to
a network host using a connection oriented socket type.
since: 2.22
SocketConnection
GSocketConnection is a GIOStream for a connected socket. They
can be created either by GSocketClient when connecting to a host,
or by GSocketListener when accepting a new client.
since: 2.22
SocketControlMessage
A GSocketControlMessage is a special-purpose utility message that
can be sent to or received from a GSocket. These types of
messages are often called ‘ancillary data’.
since: 2.22
SocketListener
A GSocketListener is an object that keeps track of a set
of server sockets and helps you accept sockets from any of the
socket, either sync or async.
since: 2.22
SocketService
A GSocketService is an object that represents a service that
is provided to the network or over local sockets. When a new
connection is made to the service the GSocketService::incoming
signal is emitted.
since: 2.22
Subprocess
GSubprocess allows the creation of and interaction with child processes.
since: 2.40
SubprocessLauncher
This class contains a set of options for launching child processes,
such as where its standard input and output will be directed, the
argument list, the environment, and more.
since: 2.40
Task
A GTask represents and manages a cancellable ‘task’.
TcpConnection
This is the subclass of GSocketConnection that is created
for TCP/IP sockets.
since: 2.22
TcpWrapperConnection
A GTcpWrapperConnection can be used to wrap a GIOStream that is
based on a GSocket, but which is not actually a
GSocketConnection. This is used by GSocketClient so
that it can always return a GSocketConnection, even when the
connection it has actually created is not directly a
GSocketConnection.
since: 2.28
TestDBus
A helper class for testing code which uses D-Bus without touching the user’s
session bus.
since: 2.34
ThemedIcon
GThemedIcon is an implementation of GIcon that supports icon themes.
ThreadedResolver

Gio UI
Cross-Platform GUI for Go
Getting Started
Showcase
Why?
Sponsors
Gio is a library for writing cross-platform immediate mode GUI-s in Go. Gio
supports all the major platforms: Linux, macOS, Windows, Android, iOS, FreeBSD,
OpenBSD and WebAssembly.
For a quick demonstration take a look at the WebAssembly demo below.
This requires a browser that supports WebAssembly.
The source for the Kitchen project.
Getting Started
Gio is designed to work with very few dependencies. It depends only on the
platform libraries for window management, input and GPU drawing.
To install the necessary dependencies, take a look at:
Linux
Windows
macOS
Android
iOS / tvOS
WebAssembly
Once you have everything installed head over to Learn, which
contains links to get you started with Gio.

Why?
Gio helps Go developers to build efficient, fluid, and portable GUIs across
all major platforms. It combines bleeding-edge 2D graphics technology with the
flexibility of the immediate mode graphics paradigm to create a compelling and
consistent foundation for application development.
Gio includes an efficient vector renderer based on the Pathfinder project implemented on OpenGL ES and Direct3D 11,
and is migrating towards an even more efficient compute-shader-based renderer
built atop piet-gpu. Text and other
shapes are rendered using only their outlines without baking them into texture
images, to support efficient animations, transformed drawing and pixel
resolution independence.
Sponsors
Development of Gio is funded by sponsorships. If you find Gio useful, please consider sponsoring the
project on OpenCollective or one or more of its developers directly.

通过 Gio 构建 Go GUI 程序 通过 Gio 构建 Go GUI 程序 幽鬼 2021-10-18 3079
争做团队核心程序员，关注「幽鬼」GUI 不是 Go 语言擅长的领域，但社区一直在努力，让 Go 进入 GUI 领域，于是有了 fyne、gio 等这样的 GUI 框架。今天起，给大家带来一系列 Gio 教程，尝试从零开始构建一个 Gio GUI 程序。本系列基于 Go1.17，而 Gio 没有发布具体的版本01 Gio 是什么Gio 在 Go 中实现了可移植的即时模式 GUI 程序。Gio 程序可在所有主要平台上运行：iOS/tvOS、Android、Linux (Wayland/X11)、macOS、Windows、FreeBSD、OpenBSD 和对浏览器的实验性支持 (Webassembly/WebGL)。有一个用于在虚拟机中运行 Gio 程序的 unikernel 端口[1]。Gio 包括一个基于 Pathfinder 项目[2]的高效矢量渲染器，以及一个基于 piet-gpu 项目[3]的实验渲染器。两种渲染器都支持 Vulkan、Metal、Direct3D 11 和 OpenGL ES。对于低端设备，有一个在未扩展的 OpenGL ES 2.0 上运行的 CPU 回调。文本和其他形状仅使用其轮廓进行渲染，而无需将它们烘焙成纹理图像，以支持高效动画、转换绘图和显示分辨率独立性。Gio 的代码在 https://git.sr.ht/~eliasnaur/gio，在 GitHub 上有镜像：https://github.com/gioui/gio。02 运行官方的示例Gio 设计时让依赖尽可能少。它仅依赖用于窗口管理、输入和 GPU 绘图的平台库。官方提供了一个 Hello 程序，执行如下命令：$ go run gioui.org/example/hello@latest成功会打开一个窗口：另外一个更复杂的例子，material design 的 widgets：$ go run gioui.org/example/kitchen@latest结果：这些示例教程可以在 https://github.com/gioui/gio-example 找到。03 系列教程虽然命令行很棒，但 95% 的用户不是高级用户。他们想要按下按钮，切换开关，然后继续他们的生活。Gio 是一个很棒的工具包，用于构建满足你需求的精美、闪电般快速、灵活的用户界面。该系列由 10 个教程组成，我们将完全从零开始，并构建一个自包含的 GUI 应用程序：本系列教程基于 https://jonegil.github.io/gui-with-gio/，但不是简单的翻译。欢迎对 gio 感兴趣的一起交流。参考资料[1]unikernel 端口: https://eliasnaur.com/unik[2]Pathfinder 项目: https://github.com/servo/pathfinder[3]piet-gpu 项目: https://github.com/linebender/piet-gpu往期推荐怎么回事？Go 标准库 sync 包中竟然包含一个 porn 网址欢迎关注「幽鬼」，像她一样做团队的核心。

最近这些事件的主角，初心绝对不是什么为了创造啥，为的只是赚钱。开源只是赚钱手段，而且是觉得自己为了钱放弃很多的那种心态，心理先把自己当成了牺牲者，然后认为所有人都应该补偿自己。不拿钱补偿就是忘恩负义的白眼狼！

我人品咋了？就事论事就是人品有问题？对我简介都这么关心？我都忘了自己写了什么了。是不是爱一点点国，就是眼中钉了？是不是爱国必须表现装给你们看才行？评论一个社会事件怎么搞到爱国程度了？我就事论事，让某些人不要总是用嫉妒心看待别人，只能害了自己，难道不对？

没有人要求你必须要维护必须开源。但是你有权力要求用户“不得以任何形式传播及公开”吗？这是 AGPL 开源协议所允许的吗？如果你连开源协议都搞不清楚，早点把仓库归档吧。整得跟小学生耍流氓一样。

你说的很对，能源的确是另一个很重要的方面。但是AI和挖矿不一样，他的使用是要比训练少数量级差别的算力的。而AI能达到的功能是由训练实现的。目前情况下，电力很多国家都够支撑，但是芯片实现的算力全世界只有为数不多的AI公司才能有条件训练大模型了。对比小模型就能看出来，小模型是个人能训练的。

这事没啥好讨论的啊，代码如果开始的时候是开源，那么你有闭源的权利，但是要从声明之后的版本开始，不能回溯。文档也是如此，但是有一点，如果文档虽然没有声明开源，但是自己在公开场合发布过，你可以建议请求不要随意传播，但是不能强硬的禁止。关于白嫖，这个说法过分了，对于这些想要商业化的项目，开源伊始的初心，无非是面推广费、免费测试。各有所图，不要互相指责。

开源不是不可以收费，基本上也没人认为开源项目里有收费项目是什么十恶不赦的罪过。问题在于，你要合理合法，要符合开源的道德。最近的事件，要么是某和尚绑票，不合理不合法更没道德，绑票拿赎金。要么就是这位，明明合法的事情，偏偏发个歧视公告，张嘴白嫖闭嘴白嫖，过嘴瘾有意思吗？开源生意，哪怕你心理一万个不愿意，但是既然你做了这个生意，伪君子人设好歹你不干的时候再扔呀，一会儿伪君子一会儿真小人，觉得不找骂才怪。

这篇说的好听，但你心里，公有制就是白嫖，你之前公告写着“ioGame21 在线文档依旧采用自愿付费模式策略。简单的说，我们提供了最新在线文档的白嫖方式，如果你打算跟进框架最新版本的，依旧可以选择白嫖在线文档。”，“综上，想继续白嫖的，请跟进最新版本。”不是吗？这是什么理念？我看更像精神分裂的理念，伪君子和真小人之间来回切换，嘴上都不一致。

Hello, Gio!
Creating a new package
Creating the program
Creating the window
Creating a theme
Listening for events
Drawing the text
This example does a really quick introduction on getting something up and
running. It does not explain all the details, those will be covered in
another tutorial.
Ensure that you have followed installation instructions.
If everything is setup correctly, then running:
go run gioui.org/example/hello@latest
Should display a pretty “Hello, Gio!” message.
Creating a new package
If you are unfamiliar with Go, then more help can be found at go.dev/learn.
First step in creating a Go program requires setting up the module.
We’ll use gio.test as our module name, however, it’s recommended to use a
repository name when you want to upload it. The module name can be later changed.
go mod init gio.test
Creating the program
Let’s create main.go with the following code:
package main
import (
"image/color"
"log"
"os"
"gioui.org/app"
"gioui.org/op"
"gioui.org/text"
"gioui.org/widget/material"
)
func main() {
go func() {
w := app.NewWindow()
err := run(w)
if err != nil {
log.Fatal(err)
}
os.Exit(0)
}()
app.Main()
}
func run(w *app.Window) error {
th := material.NewTheme()
var ops op.Ops
for {
switch e := w.NextEvent().(type) {
case app.DestroyEvent:
return e.Err
case app.FrameEvent:
// This graphics context is used for managing the rendering state.
gtx := app.NewContext(&ops, e)
// Define an large label with an appropriate text:
title := material.H1(th, "Hello, Gio")
// Change the color of the label.
maroon := color.NRGBA{R: 127, G: 0, B: 0, A: 255}
title.Color = maroon
// Change the position of the label.
title.Alignment = text.Middle
// Draw the label to the graphics context.
title.Layout(gtx)
// Pass the drawing operations to the GPU.
e.Frame(gtx.Ops)
}
}
}
Let’s then update all the dependencies with:
go mod tidy
Once that succeeds, the program should start up with:
go run .
Now to explain what’s happening.
Creating the window
Every program requires a window, the main starts up the application loop that
talks to the operating system and starts the window logic in a separate
goroutine.
func main() {
go func() {
w := app.NewWindow()
err := run(w)
if err != nil {
log.Fatal(err)
}
os.Exit(0)
}()
app.Main()
}
Creating a theme
Applications need to define their fonts and different color settings.
Themes contain all the necessary information.
func run(w *app.Window) error {
th := material.NewTheme()
Listening for events
The communication with the operating system (i.e. keyboard, mouse, GPU) happens
through events. Gio uses the following approach to process events:
for {
switch e := w.NextEvent().(type) {
case app.DestroyEvent:
return e.Err
case app.FrameEvent:
app.DestroyEvent means the user pressed the close button.
app.FrameEvent means the program should handle input and render a new
frame.
Drawing the text
To draw the text it needs to go through several stages:
// This graphics context is used for managing the rendering state.
gtx := app.NewContext(&ops, e)
// Define an large label with an appropriate text:
title := material.H1(th, "Hello, Gio")
// Change the color of the label.
maroon := color.NRGBA{R: 127, G: 0, B: 0, A: 255}
title.Color = maroon
// Change the position of the label.
title.Alignment = text.Middle
// Draw the label to the graphics context.
title.Layout(gtx)
// Pass the drawing operations to the GPU.
e.Frame(gtx.Ops)

12.6. 可用的 GIO 命令
GIO 提供一些对脚本或测试可能有用的命令。
以下是一组 POSIX 命令的对应命令，如下所示：
命令描述
gio cat
显示文件的内容.
gio mkdir
创建新目录。
gio rename
重命名文件。
gio mount
提供对 gio 挂载功能的各个方面的访问。
gio set
设置文件上的文件属性。
gio copy
制作文件的副本。
gio list
列出目录内容。
gio move
将文件从一个地方移到另一个地方。
gio remove
删除文件。
gio trash
将文件或目录发送到 垃圾桶。根据文件所在的位置，这可能是不同的文件夹，并非所有文件系统都支持这个概念。在文件存在于用户主目录中的常见情形，回收文件夹为 $XDG_DATA_HOME/Trash。
gio info
显示给定位置的信息。
gio save
从标准输入读取数据，并将数据保存到给定位置。
gio tree
以类似于树的格式，递归列出指定位置的内容。如果未指定位置，则默认为当前目录。
以下额外的命令提供更多对 GIO 细节的控制：
命令描述
gio monitor
监控文件或目录的更改，如创建、删除、内容和属性的更改，以及影响监控位置的挂载和卸载操作。
gio mime
如果未指定处理程序，则列出 mimetype 的注册的和推荐的应用程序，否则，它被设置为 mimetype 的默认处理程序。
gio open
使用默认的应用程序来打开文件，该应用程序被注册来处理此类文件。
注意
为方便用户，bash 完成作为软件包的一部分提供。
所有这些命令都是原生 GIO 客户端，不需要运行备用的 FUSE 守护进程。它们的目的不是代替 POSIX 命令，实际上，支持的切换范围极小。在它们的基本形式中，这些命令使用 URI 字符串作为参数，而不是本地路径。
