Simplifying boolean value configs

[xq114]

你在什么场景下需要该功能？

对于有很多组件/设置的包，一个个指定比较繁琐

add_requires("boost >=1.78.0", {configs = {iostreams = true, system = true, thread = true}})

描述可能的解决方案

#5527

希望3.0中可以简化设置，支持

add_requires("boost[iostreams,system,thread] >=1.78.0")

等价于在原有configs后追加iostreams = true, system = true, thread = true

描述你认为的候选方案

add_requires("boost >=1.78.0", {configs = ["iostreams", "system", "thread"])

若传入list则认为是config名称；这种做法灵活性比上一种差，但对现有语法变动小

In what scenario do you need this function?

For packages with many components/settings, specifying them one by one is cumbersome.

add_requires("boost >=1.78.0", {configs = {iostreams = true, system = true, thread = true}})

Describe possible solutions

#5527

It is hoped that the settings can be simplified in 3.0 and supported

add_requires("boost[iostreams,system,thread] >=1.78.0")

Equivalent to appending iostreams = true, system = true, thread = true after the original configs

Describe your alternatives

add_requires("boost >=1.78.0", {configs = ["iostreams", "system", "thread"])

If a list is passed in, it is considered to be the config name; this method is less flexible than the previous one, but it has less changes to the existing syntax.

add_requires("thorvg", {configs = {

    tools = {"svg2png"}
}})

xmake-io/xmake-repo@a3db979/packages/t/thorvg/xmake.lua#L19-L23

add_requires("thorvg", {configs = {
    loaders = {"svg", "png"},
    tools = {"svg2png"}
}})

这么写就更复杂了，尤其是90%的情况只需要一个配置xxx=true

``lua
add_requires("thorvg", {configs = {
loaders = {"svg", "png"},
tools = {"svg2png"}
}})

Writing this way is more complicated, especially in 90% of cases only one configuration xxx=true is needed

可以考虑 ，还可以带上string值。复杂的，array values 这种，就用 configs = {} 配。

add_requires("boost[iostreams,system,thread,key=value] >=1.78.0")
add_requires("boost[iostreams=y,thread=n] >=1.78.0")

xrepo install boost[iostreams,system,thread,key=value]

[waruqi]

这个实现比较简单，并且没啥副作用，可以提前进去，试试这个 patch #5736

[waruqi]

改进了下，还能支持 array values

 xrepo install ffmpeg[shared,debug,codecs=[foo,bar,zoo]]

反对一个功能有多种写法，这会给以后交流学习，教程编写带来分歧，会进一步误导新手。

add_requires("boost >=1.78.0", {configs = {iostreams = true, system = true, thread = true}})

复制不就行了，难道真手敲？

It is against having multiple ways to write a function, which will cause differences in future communication and learning, and tutorial writing, and will further mislead novices.

add_requires("boost >=1.78.0", {configs = {iostreams = true, system = true, thread = true}})

Isn’t it enough to just copy it? Is it possible to type it by hand?

[waruqi]

目前限制仅对 xmake 包生效，三方包不启用，因为 vcpkg::boost[core] 等三方包有自己的包名格式，会冲突

The current restriction only takes effect for the xmake package. Third-party packages are not enabled because third-party packages such as vcpkg::boost[core] have their own package name formats and will conflict.

都写c++了，一种功能多种写法应该习惯了，自己选择吧

I've all written C++, so I should be used to writing one function in multiple ways. You can make your own choice.
