---- The luv project provides access to the multi-platform support library ---- libuv in Lua code. It was primarily developed for the luvit project as ---- the built-in `uv` module, but can be used in other Lua environments. ---- ---- More information about the core libuv library can be found at the original ---- libuv documentation page. ---- ---- ---- Here is a small example showing a TCP echo server: ---- ---- ```lua ---- local uv = require("luv") -- "luv" when stand-alone, "uv" in luvi apps ---- ---- local server = uv.new_tcp() ---- server:bind("127.0.0.1", 1337) ---- server:listen(128, function (err) ---- assert(not err, err) ---- local client = uv.new_tcp() ---- server:accept(client) ---- client:read_start(function (err, chunk) ---- assert(not err, err) ---- if chunk then ---- client:write(chunk) ---- else ---- client:shutdown() ---- client:close() ---- end ---- end) ---- end) ---- print("TCP server listening at 127.0.0.1 port 1337") ---- uv.run() -- an explicit run call is necessary outside of luvit ---- ``` ---- ---- ---- The luv library contains a single Lua module referred to hereafter as `uv` for ---- simplicity. This module consists mostly of functions with names corresponding to ---- their original libuv versions. For example, the libuv function `uv_tcp_bind` has ---- a luv version at `uv.tcp_bind`. Currently, only one non-function field exists: ---- `uv.constants`, which is a table. ---- ---- ---- In addition to having simple functions, luv provides an optional method-style ---- API. For example, `uv.tcp_bind(server, host, port)` can alternatively be called ---- as `server:bind(host, port)`. Note that the first argument `server` becomes the ---- object and `tcp_` is removed from the function name. Method forms are ---- documented below where they exist. ---- ---- ---- Functions that accept a callback are asynchronous. These functions may ---- immediately return results to the caller to indicate their initial status, but ---- their final execution is deferred until at least the next libuv loop iteration. ---- After completion, their callbacks are executed with any results passed to it. ---- ---- Functions that do not accept a callback are synchronous. These functions ---- immediately return their results to the caller. ---- ---- Some (generally FS and DNS) functions can behave either synchronously or ---- asynchronously. If a callback is provided to these functions, they behave ---- asynchronously; if no callback is provided, they behave synchronously. ---- ---- ---- Some unique types are defined. These are not actual types in Lua, but they are ---- used here to facilitate documenting consistent behavior: ---- - `fail`: an assertable `nil, string, string` tuple (see Error handling) ---- - `callable`: a `function`; or a `table` or `userdata` with a `__call` ---- metamethod ---- - `buffer`: a `string` or a sequential `table` of `string`s ---- - `threadargs`: variable arguments (`...`) of type `nil`, `boolean`, `number`, ---- `string`, or `userdata` ---- ---- ---- This documentation is mostly a retelling of the libuv API documentation ---- within the context of luv's Lua API. Low-level implementation details and ---- unexposed C functions and types are not documented here except for when they ---- are relevant to behavior seen in the Lua module. ---- ---- [Error handling]: #error-handling ---- ---- In libuv, errors are negative numbered constants; however, these errors and the ---- functions used to handle them are not exposed to luv users. Instead, if an ---- internal error is encountered, the luv function will return to the caller an ---- assertable `nil, err, name` tuple. ---- ---- - `nil` idiomatically indicates failure ---- - `err` is a string with the format `{name}: {message}` ---- - `{name}` is the error name provided internally by `uv_err_name` ---- - `{message}` is a human-readable message provided internally by `uv_strerror` ---- - `name` is the same string used to construct `err` ---- ---- This tuple is referred to below as the `fail` pseudo-type. ---- ---- When a function is called successfully, it will return either a value that is ---- relevant to the operation of the function, or the integer `0` to indicate ---- success, or sometimes nothing at all. These cases are documented below. ---- ---- ---- [reference counting]: #reference-counting ---- ---- The libuv event loop (if run in the default mode) will run until there are no ---- active and referenced handles left. The user can force the loop to exit early by ---- unreferencing handles which are active, for example by calling `uv.unref()` ---- after calling `uv.timer_start()`. ---- ---- A handle can be referenced or unreferenced, the refcounting scheme doesn't use a ---- counter, so both operations are idempotent. ---- ---- All handles are referenced when active by default, see `uv.is_active()` for a ---- more detailed explanation on what being active involves. ---- ---- ---- [File system operations]: #file-system-operations ---- ---- Most file system functions can operate synchronously or asynchronously. When a synchronous version is called (by omitting a callback), the function will ---- immediately return the results of the FS call. When an asynchronous version is ---- called (by providing a callback), the function will immediately return a ---- `uv_fs_t userdata` and asynchronously execute its callback; if an error is encountered, the first and only argument passed to the callback will be the `err` error string; if the operation completes successfully, the first argument will be `nil` and the remaining arguments will be the results of the FS call. ---- ---- Synchronous and asynchronous versions of `readFile` (with naive error handling) ---- are implemented below as an example: ---- ---- ```lua ---- local function readFileSync(path) ---- local fd = assert(uv.fs_open(path, "r", 438)) ---- local stat = assert(uv.fs_fstat(fd)) ---- local data = assert(uv.fs_read(fd, stat.size, 0)) ---- assert(uv.fs_close(fd)) ---- return data ---- end ---- ---- local data = readFileSync("main.lua") ---- print("synchronous read", data) ---- ``` ---- ---- ```lua ---- local function readFile(path, callback) ---- uv.fs_open(path, "r", 438, function(err, fd) ---- assert(not err, err) ---- uv.fs_fstat(fd, function(err, stat) ---- assert(not err, err) ---- uv.fs_read(fd, stat.size, 0, function(err, data) ---- assert(not err, err) ---- uv.fs_close(fd, function(err) ---- assert(not err, err) ---- return callback(data) ---- end) ---- end) ---- end) ---- end) ---- end ---- ---- readFile("main.lua", function(data) ---- print("asynchronous read", data) ---- end) ---- ``` ---- ---- ---- [Thread pool work scheduling]: #thread-pool-work-scheduling ---- ---- Libuv provides a threadpool which can be used to run user code and get notified ---- in the loop thread. This threadpool is internally used to run all file system ---- operations, as well as `getaddrinfo` and `getnameinfo` requests. ---- ---- ```lua ---- local function work_callback(a, b) ---- return a + b ---- end ---- ---- local function after_work_callback(c) ---- print("The result is: " .. c) ---- end ---- ---- local work = uv.new_work(work_callback, after_work_callback) ---- ---- work:queue(1, 2) ---- ---- -- output: "The result is: 3" ---- ``` ---- ---- ---- [DNS utility functions]: #dns-utility-functions ---- ---- ---- [Threading and synchronization utilities]: #threading-and-synchronization-utilities ---- ---- Libuv provides cross-platform implementations for multiple threading an ---- synchronization primitives.
