6. Different types of streams 44.7. How to create a readable stream 44.8. How to create a writable stream 44.9. How to get data from a readable stream 44.10. How to send data to a writable stream yellow is much more convenient than trying to remember the escape codes, and the code is much more readable. Check the project link posted above for more usage examples. 13.9. Create a progress bar Progress close a file descriptor fs.copyFile() : copies a file 118 fs.createReadStream() : create a readable file stream fs.createWriteStream() : create a writable file stream fs.link() : create a new

operations (e.g. ==, <, =, and <<), and adhering to those conventions can make user-defined types more readable and enable them to interoperate with libraries that expect those names. User-defined literals are return types only where using the ordinary syntax (leading return types) is impractical or much less readable. C++ allows two different forms of function declarations. In the older form, the return type appears sometimes specifying it explicitly would be clearer for readers. Sometimes it’s easier and more readable to specify a return type after the func- tion’s parameter list has already appeared. This is particularly

Streams 流  Readable Stream 可读流 o Event: 'data' 事件：'data' o Event: 'end' 事件：'end' o Event: 'error' 事件：'error' o Event: 'close' 事件：'close' o Event: 'fd' 事件：'fd' o stream.readable o stream. h）中有详细文档。  libev, C event loop library. Anytime one needs to wait for a file descriptor to become readable, wait for a timer, or wait for a signal to received one will need to interface with libev. That 是阻塞式的。 process.stdin A Readable Stream for stdin. The stdin stream is paused by default, so one must call process.stdin.resume() to read from it. 一个到标准输入的可读流 Readable Stream。默认情况下标准输入流是暂停的， 要从中读取内容需要调用方法

Svelte Bindings 9 to writable stores, Svelte provides 2 special kinds of stores: readable stores and derived stores. 6.4. Svelte Readable Stores Readable stores are special because they can't be updated from the outside using writable() to initialize the store variable, we use readable() : import { readable } from 'svelte/store' export const count = readable(0) You can provide a function after the default value, that

Value mapping support has been added in map labels so that raw values can be represented in a human-readable way. 12.1.4 Improved performance of System status widget The performance of the dashboard System uptime System uptime in seconds. Integer In item configuration, use s or uptime units to get readable values. system.users.num Number of users logged in. Integer who command is used on the agent example, an item which has value ’0’ or ’1’ can use value mapping to represent the values in a human-readable form: • ’0’ => ’Not Available’ • ’1’ => ’Available’ Thus, when configuring items you can use
