复制操作

此组件为元素（主要用于代码块）添加一个复制按钮，该按钮将元素的内容写入剪贴板。

puts "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum
  has been the industry's standard dummy text ever since the 1500s, when an unknown printer."

代码

This component adds a copy button to an element (primarily intended for code blocks)
which writes the content of the element to the clipboard.

<div class="enable-copy-action">
{% highlight crystal %}
puts "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum
  has been the industry's standard dummy text ever since the 1500s, when an unknown printer."

基础

Crystal 的 语法大量借鉴了 Ruby 的语法。

所以它读起来很自然，易于编写，并且对于经验丰富的 Ruby 开发人员来说，学习曲线更低：cat [crystal](https://) > /dev/brain。

简洁的语法让它易于被人类读取，但它在机器上也很快。

在 Crystal 论坛 上，你可以遇到对 Crystal 感兴趣的人类。

按 Ctr+C 结束进程。

代码

**Crystal’s** syntax is *heavily* inspired by [Ruby’s](https://ruby-lang.org.cn/).

So it feels natural to read and ***easy*** to write, and has the added benefit of
a lower learning curve for experienced Ruby devs: `cat [crystal](https://) > /dev/brain`.

The **slick** syntax makes it easy to `read` for humans, but it's also [**fast** on machines](/).

On [the *Crystal Forum* you can meet `humans` interested in Crystal](https://forum.crystal-lang.org).

Press <kbd>Ctr+C</kbd> to end the process.

Crystal 中的所有类型都是非空类型，空类型变量表示为类型和 nil 的并集。

if rand(2) > 0
  my_string = "hello world"
end

puts my_string.upcase

$ crystal build hello-world.cr
$ ./hello-world
Hello World!

class Object
  def has_instance_var?(name) : Bool{{ @type.instance_vars.map &.name.stringify }}.includes? name
  end
end

class Person
  property name : String

  def initialize(@name)
  end
end

person = Person.new "John"
p! person.has_instance_var?("name") # => true
p! person.has_instance_var?("birthday") # => false

代码

```crystal
# A very basic HTTP server
require "http/server"

server = HTTP::Server.new do |context|
  context.response.content_type = "text/plain"
  context.response.print "Hello world, got #{context.request.path}!"
end

puts "Listening on http://127.0.0.1:8080"
server.listen(8080)
```

```yaml

All types are non-nilable in Crystal, and nilable variables are represented as a union between the type and nil.

```
if rand(2) > 0
  my_string = "hello world"
end

puts my_string.upcase
```

```terminal
$ crystal build hello-world.cr
$ ./hello-world
Hello World!
```

```crystal
class Object
  def has_instance_var?(name) : Bool
    {{- "{{" }} @type.instance_vars.map &.name.stringify }}.includes? name
  end
end

class Person
  property name : String

  def initialize(@name)
  end
end

person = Person.new "John"
p! person.has_instance_var?("name") # => true
p! person.has_instance_var?("birthday") # => false
```
