# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## `0.5.2` - February 26th, 2023 ### Fixed - Fixed crash when using `stdio.color()` or `stdio.style()` in a CI environment or non-interactive terminal ## `0.5.1` - February 25th, 2023 ### Added - Added `net.encode` and `net.decode` which are equivalent to `net.jsonEncode` and `net.jsonDecode`, but with support for more formats. **_WARNING: Unstable API_** _This API is unstable and may change or be removed in the next major version of Lune. The purpose of making a new release with these functions is to gather feedback from the community, and potentially replace the JSON-specific encoding and decoding utilities._ Example usage: ```lua local toml = net.decode("toml", [[ [package] name = "my-cool-toml-package" version = "0.1.0" [values] epic = true ]]) assert(toml.package.name == "my-cool-toml-package") assert(toml.package.version == "0.1.0") assert(toml.values.epic == true) ``` ### Fixed - Fixed indentation of closing curly bracket when printing tables ## `0.5.0` - February 23rd, 2023 ### Added - Added auto-generated API reference pages and documentation using GitHub wiki pages - Added support for `query` in `net.request` parameters, which enables usage of query parameters in URLs without having to manually URL encode values. - Added a new function `fs.move` to move / rename a file or directory from one path to another. - Implemented a new task scheduler which resolves several long-standing issues: - Issues with yielding across the C-call/metamethod boundary no longer occur when calling certain async APIs that Lune provides. - Ordering of interleaved calls to `task.spawn/task.defer` is now completely deterministic, deferring is now guaranteed to run last even in these cases. - The minimum wait time possible when using `task.wait` and minimum delay time using `task.delay` are now much smaller, and only limited by the underlying OS implementation. For most systems this means `task.wait` and `task.delay` are now accurate down to about 5 milliseconds or less. ### Changed - Type definitions are now bundled as part of the Lune executable, meaning they no longer need to be downloaded. - `lune --generate-selene-types` will generate the Selene type definitions file, replacing `lune --download-selene-types` - `lune --generate-luau-types` will generate the Luau type definitions file, replacing `lune --download-luau-types` - Improved accuracy of Selene type definitions, strongly typed arrays are now used where possible - Improved error handling and messages for `net.serve` - Improved error handling and messages for `stdio.prompt` - File path representations on Windows now use legacy paths instead of UNC paths wherever possible, preventing some confusing cases where file paths don't work as expected ### Fixed - Fixed `process.cwd` not having the correct ending path separator on Windows - Fixed remaining edge cases where the `task` and `coroutine` libraries weren't interoperable - Fixed `task.delay` keeping the script running even if it was cancelled using `task.cancel` - Fixed `stdio.prompt` blocking all other lua threads while prompting for input ## `0.4.0` - February 11th, 2023 ### Added - ### Web Sockets `net` now supports web sockets for both clients and servers!
Note that the web socket object is identical on both client and server, but how you retrieve a web socket object is different. #### Server API The server web socket API is an extension of the existing `net.serve` function.
This allows for serving both normal HTTP requests and web socket requests on the same port. Example usage: ```lua net.serve(8080, { handleRequest = function(request) return "Hello, world!" end, handleWebSocket = function(socket) task.delay(10, function() socket.send("Timed out!") socket.close() end) -- The message will be nil when the socket has closed repeat local messageFromClient = socket.next() if messageFromClient == "Ping" then socket.send("Pong") end until messageFromClient == nil end, }) ``` #### Client API Example usage: ```lua local socket = net.socket("ws://localhost:8080") socket.send("Ping") task.delay(5, function() socket.close() end) -- The message will be nil when the socket has closed repeat local messageFromServer = socket.next() if messageFromServer == "Ping" then socket.send("Pong") end until messageFromServer == nil ``` ### Changed - `net.serve` now returns a `NetServeHandle` which can be used to stop serving requests safely. Example usage: ```lua local handle = net.serve(8080, function() return "Hello, world!" end) print("Shutting down after 1 second...") task.wait(1) handle.stop() print("Shut down succesfully") ``` - The third and optional argument of `process.spawn` is now a global type `ProcessSpawnOptions`. - Setting `cwd` in the options for `process.spawn` to a path starting with a tilde (`~`) will now use a path relative to the platform-specific home / user directory. - `NetRequest` query parameters value has been changed to be a table of key-value pairs similar to `process.env`. If any query parameter is specified more than once in the request url, the value chosen will be the last one that was specified. - The internal http client for `net.request` now reuses headers and connections for more efficient requests. - Refactored the Lune rust crate to be much more user-friendly and documented all of the public functions. ### Fixed - Fixed `process.spawn` blocking all lua threads if the spawned child process yields. ## `0.3.0` - February 6th, 2023 ### Added - Added a new global `stdio` which replaces `console` - Added `stdio.write` which writes a string directly to stdout, without any newlines - Added `stdio.ewrite` which writes a string directly to stderr, without any newlines - Added `stdio.prompt` which will prompt the user for different kinds of input Example usage: ```lua local text = stdio.prompt() local text2 = stdio.prompt("text", "Please write some text") local didConfirm = stdio.prompt("confirm", "Please confirm this action") local optionIndex = stdio.prompt("select", "Please select an option", { "one", "two", "three" }) local optionIndices = stdio.prompt( "multiselect", "Please select one or more options", { "one", "two", "three", "four", "five" } ) ``` ### Changed - Migrated `console.setColor/resetColor` and `console.setStyle/resetStyle` to `stdio.color` and `stdio.style` to allow for more flexibility in custom printing using ANSI color codes. Check the documentation for new usage and behavior. - Migrated the pretty-printing and formatting behavior of `console.log/info/warn/error` to the standard Luau printing functions. ### Removed - Removed printing functions `console.log/info/warn/error` in favor of regular global functions for printing. ### Fixed - Fixed scripts hanging indefinitely on error ## `0.2.2` - February 5th, 2023 ### Added - Added global types for networking & child process APIs - `net.request` gets `NetFetchParams` and `NetFetchResponse` for its argument and return value - `net.serve` gets `NetRequest` and `NetResponse` for the handler function argument and return value - `process.spawn` gets `ProcessSpawnOptions` for its third and optional parameter ### Changed - Reorganize repository structure to take advantage of cargo workspaces, improves compile times ## `0.2.1` - February 3rd, 2023 ### Added - Added support for string interpolation syntax (update to Luau 0.561) - Added network server functionality using `net.serve` Example usage: ```lua net.serve(8080, function(request) print(`Got a {request.method} request at {request.path}!`) local data = net.jsonDecode(request.body) -- For simple text responses with a 200 status return "OK" -- For anything else return { status = 203, headers = { ["Content-Type"] = "application/json" }, body = net.jsonEncode({ message = "echo", data = data, }) } end) ``` ### Changed - Improved type definitions file for Selene, now including constants like `process.env` + tags such as `readonly` and `mustuse` wherever applicable ### Fixed - Fixed type definitions file for Selene not including all API members and parameters - Fixed `process.exit` exiting at the first yield instead of exiting instantly as it should ## `0.2.0` - January 28th, 2023 ### Added - Added full documentation for all global APIs provided by Lune! This includes over 200 lines of pure documentation about behavior & error cases for all of the current 35 constants & functions. Check the [README](/README.md) to find out how to enable documentation in your editor. - Added a third argument `options` for `process.spawn`: - `cwd` - The current working directory for the process - `env` - Extra environment variables to give to the process - `shell` - Whether to run in a shell or not - set to `true` to run using the default shell, or a string to run using a specific shell - `stdio` - How to treat output and error streams from the child process - set to `"inherit"` to pass output and error streams to the current process - Added `process.cwd`, the path to the current working directory in which the Lune script is running ## `0.1.3` - January 25th, 2023 ### Added - Added a `--list` subcommand to list scripts found in the `lune` or `.lune` directory. ## `0.1.2` - January 24th, 2023 ### Added - Added automatic publishing of the Lune library to [crates.io](https://crates.io/crates/lune) ### Fixed - Fixed scripts that terminate instantly sometimes hanging ## `0.1.1` - January 24th, 2023 ### Fixed - Fixed errors containing `./` and / or `../` in the middle of file paths - Potential fix for spawned processes that yield erroring with "attempt to yield across metamethod/c-call boundary" ## `0.1.0` - January 24th, 2023 ### Added - `task` now supports passing arguments in `task.spawn` / `task.delay` / `task.defer` - `require` now uses paths relative to the file instead of being relative to the current directory, which is consistent with almost all other languages but not original Lua / Luau - this is a breaking change but will allow for proper packaging of third-party modules and more in the future. - **_NOTE:_** _If you still want to use the default Lua behavior instead of relative paths, set the environment variable `LUAU_PWD_REQUIRE` to `true`_ ### Changed - Improved error message when an invalid file path is passed to `require` - Much improved error formatting and stack traces ### Fixed - Fixed downloading of type definitions making json files instead of the proper format - Process termination will now always make sure all lua state is cleaned up before exiting, in all cases ## `0.0.6` - January 23rd, 2023 ### Added - Initial implementation of [Roblox's task library](https://create.roblox.com/docs/reference/engine/libraries/task), with some caveats: - Minimum wait / delay time is currently set to 10ms, subject to change - It is not yet possible to pass arguments to tasks created using `task.spawn` / `task.delay` / `task.defer` - Timings for `task.defer` are flaky and deferred tasks are not (yet) guaranteed to run after spawned tasks With all that said, everything else should be stable! - Mixing and matching the `coroutine` library with `task` works in all cases - `process.exit()` will stop all spawned / delayed / deferred threads and exit the process - Lune is guaranteed to keep running until there are no longer any waiting threads If any of the abovementioned things do not work as expected, it is a bug, please file an issue! ### Fixed - Potential fix for spawned processes that yield erroring with "attempt to yield across metamethod/c-call boundary" ## `0.0.5` - January 22nd, 2023 ### Added - Added full test suites for all Lune globals to ensure correct behavior - Added library version of Lune that can be used from other Rust projects ### Changed - Large internal changes to allow for implementing the `task` library. - Improved general formatting of errors to make them more readable & glanceable - Improved output formatting of non-primitive types - Improved output formatting of empty tables ### Fixed - Fixed double stack trace for certain kinds of errors ## `0.0.4` - January 21st, 2023 ### Added - Added `process.args` for inspecting values given to Lune when running (read only) - Added `process.env` which is a plain table where you can get & set environment variables ### Changed - Improved error formatting & added proper file name to stack traces ### Removed - Removed `...` for process arguments, use `process.args` instead - Removed individual functions for getting & setting environment variables, use `process.env` instead ## `0.0.3` - January 20th, 2023 ### Added - Added networking functions under `net` Example usage: ```lua local apiResult = net.request({ url = "https://jsonplaceholder.typicode.com/posts/1", method = "PATCH", headers = { ["Content-Type"] = "application/json", }, body = net.jsonEncode({ title = "foo", body = "bar", }), }) local apiResponse = net.jsonDecode(apiResult.body) assert(apiResponse.title == "foo", "Invalid json response") assert(apiResponse.body == "bar", "Invalid json response") ``` - Added console logging & coloring functions under `console` This piece of code: ```lua local tab = { Integer = 1234, Hello = { "World" } } console.log(tab) ``` Will print the following formatted text to the console, **_with syntax highlighting_**: ```lua { Integer = 1234, Hello = { "World", } } ``` Additional utility functions exist with the same behavior but that also print out a colored tag together with any data given to them: `console.info`, `console.warn`, `console.error` - These print out prefix tags `[INFO]`, `[WARN]`, `[ERROR]` in blue, orange, and red, respectively. ### Changed - The `json` api is now part of `net` - `json.encode` becomes `net.jsonEncode` - `json.decode` become `net.jsonDecode` ### Fixed - Fixed JSON decode not working properly ## `0.0.2` - January 19th, 2023 ### Added - Added support for command-line parameters to scripts These can be accessed as a vararg in the root of a script: ```lua local firstArg: string, secondArg: string = ... print(firstArg, secondArg) ``` - Added CLI parameters for downloading type definitions: - `lune --download-selene-types` to download Selene types to the current directory - `lune --download-luau-types` to download Luau types to the current directory These files will be downloaded as `lune.yml` and `luneTypes.d.luau` respectively and are also available in each release on GitHub. ## `0.0.1` - January 18th, 2023 Initial Release
