0.6.4 - March 26th, 2023

Fixed

• Fixed attributes not being set properly if the instance has an empty attributes property
• Fixed error messages for reading & writing roblox files not containing the full error message
• Fixed crash when trying to access an instance reference property that points to a destroyed instance
• Fixed crash when trying to save instances that contain unsupported attribute types

0.6.3 - March 26th, 2023

• Fixed accessing a destroyed instance printing an error message even if placed inside a pcall
• Fixed cloned instances not having correct instance reference properties set (ObjectValue.Value, Motor6D.Part0, ...)
• Fixed Instance::GetDescendants returning the same thing as Instance::GetChildren (oops)

0.6.2 - March 25th, 2023

This release adds some new features and fixes for the roblox built-in.

Added

• Added GetAttribute, GetAttributes and SetAttribute methods for instances
• Added support for getting & setting properties that are instance references

Changed

• Improved handling of optional property types such as optional cframes & default physical properties

Fixed

• Fixed handling of instance properties that are serialized as binary strings

0.6.1 - March 22nd, 2023

Fixed

• Fixed writePlaceFile and writeModelFile in the new roblox built-in making mysterious "ROOT" instances

0.6.0 - March 22nd, 2023

Added

• Added a roblox built-in

  If you're familiar with Remodel, this new built-in contains more or less the same APIs, integrated into Lune.
  There are just too many new APIs to list in this changelog, so head over to the docs sit to learn more!

• Added a serde built-in

  This built-in contains previously available functions encode and decode from the net global.
  The plan is for this built-in to contain more serialization and encoding functionality in the future.

• require has been reimplemented and overhauled in several ways:

  • New built-ins such as roblox and serde can only be imported using require("@lune/roblox"), require("@lune/serde"), ...
  • Previous globals such as fs, net and others can now also be imported using require("@lune/fs"), require("@lune/net"), ...
  • Requiring a script is now completely asynchronous and will not block lua threads other than the caller.
  • Requiring a script will no longer error when using async APIs in the main body of the required script.

  All new built-ins will be added using this syntax and new built-ins will no longer be available in the global scope, and current globals will stay available as globals until proper editor and LSP support is available to ensure Lune users have a good development experience. This is the first step towards moving away from adding each library as a global, and allowing Lune to have more built-in libraries in general.

  Behavior otherwise stays the same, and requires are still relative to file unless the special @ prefix is used.

• Added net.urlEncode and net.urlDecode for URL-encoding and decoding strings

Changed

• Renamed the global info function to printinfo to make it less ambiguous

Removed

• Removed experimental net.encode and net.decode functions, since they are now available using require("@lune/serde")
• Removed option to preserve default Luau require behavior

0.5.6 - March 11th, 2023

Added

• Added support for shebangs at the top of a script, meaning scripts such as this one will now run without throwing a syntax error:

  #!/usr/bin/env lune
  
  print("Hello, world!")
  

Fixed

• Fixed fs.writeFile and fs.readFile not working with strings / files that are invalid utf-8

0.5.5 - March 8th, 2023

Added

• Added support for running scripts by passing absolute file paths in the CLI
  • This does not have the restriction of scripts having to use the .luau or .lua extension, since it is presumed that if you pass an absolute path you know exactly what you are doing

Changed

• Improved error messages for passing invalid file names / file paths substantially - they now include helpful formatting to make file names distinct from file extensions, and give suggestions on how to solve the problem
• Improved general formatting of error messages, both in the CLI and for Luau scripts being run

Fixed

• Fixed the CLI being a bit too picky about file names when trying to run files in lune or .lune directories
• Fixed documentation misses from large changes made in version 0.5.0

0.5.4 - March 7th, 2023

Added

• Added support for reading scripts from stdin by passing "-" as the script name
• Added support for close codes in the net WebSocket APIs:
  • A close code can be sent by passing it to socket.close
  • A received close code can be checked with the socket.closeCode value, which is populated after a socket has been closed - note that using socket.close will not set the close code value, it is only set when received and is guaranteed to exist after closure

Changed

• Update to Luau version 0.566

Fixed

• Fixed scripts having to be valid utf8, they may now use any kind of encoding that base Luau supports
• The net WebSocket APIs will no longer return nil for partial messages being received in socket.next, and will instead wait for the full message to arrive

0.5.3 - February 26th, 2023

Fixed

• Fixed lune --generate-selene-types generating an invalid Selene definitions file
• Fixed type definition parsing issues on Windows

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:

  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:

  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:

  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:

  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:

  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:

  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 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

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, 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:

  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:

  local tab = { Integer = 1234, Hello = { "World" } }
  console.log(tab)
  

  Will print the following formatted text to the console, with syntax highlighting:

  {
      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:

  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
