## `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
