Language Server Implementation for Luau

Overview

Luau Language Server

An implementation of a language server for the Luau programming language.

Getting Started

Install the extension from the marketplace: https://marketplace.visualstudio.com/items?itemName=JohnnyMorganz.luau-lsp

The extension will automatically populate the latest API types and documentation.

To resolve your instance tree and provide module resolution, the language server uses Rojo sourcemaps. The language server will automatically create a sourcemap.json in your workspace root on startup and whenever files are added/created/renamed.

It does this by running the rojo sourcemap command, hence Rojo 7.1.0+ must be available to execute in your workspace root. It is recommend to .gitignore the sourcemap.json file. In future, the language server will generate the file internally.

By default we generate a sourcemap for a default.project.json project file. The name can be changed in extension settings, as well as whether non-script instances are included in the sourcemap (included by default). Autogeneration of sourcemaps can also be toggled completely on/off in settings - the server will instead just listen to manual changes to sourcemap.json files.

Design Goals

The initial goal is to develop a language server supporting all common LSP functions. Module resolution and typing will initially revolve around Rojo.

The idea is to ensure module resolution is customisable, allowing the server to later be easily extended to support other environments where Luau may be used. We could also potentially take it a step forward, allowing the server to be used on an Lua 5.1 codebase through a translation layer (such as type comments through EmmyLua), allowing the language server to support general purpose Lua development powered by the Luau type inference engine.

If you use Luau in a different environment and are interested in using the language server, please get in touch!

Supported Features

  • Rojo Files Resolution
  • API Type Definitions
  • Diagnostics (incl. type errors)
  • Autocompletion
  • Hover
  • Signature Help
  • Go To Definition
  • Go To Type Definition
  • Find References
  • Document Highlight
  • Document Link
  • Document Symbol
  • Color Provider
  • Rename
  • Folding Range
  • Selection Range
  • Call Hierarchy
  • Type Hierarchy
  • Semantic Tokens
  • Inlay Hints
  • Workspace Symbols

The following are extra features defined in the LSP specification, but most likely do not apply to Luau or are not necessary. They can be investigated at a later time:

  • Go To Declaration (do not apply)
  • Go To Implementation (do not apply)
  • Code Actions (not necessary - could potentially add "fixers" for lints)
  • Code Lens (not necessary)
  • Inline Value (applies for debuggers only)
  • Moniker
  • Formatting (see stylua)

Build From Source

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --target luau-lsp --config Release

  • Integration with SublimeLSP stopped working

    Integration with SublimeLSP stopped working

    This used to work just fine, but after updating to a more recent version of luau-lsp (apologies, I haven't noted the last version that worked) I'm getting this:

    Traceback (most recent call last):
  File "/home/zeux/.config/sublime-text/Installed Packages/LSP.sublime-package/plugin/core/transports.py", line 149, in invoke
  File "/home/zeux/.config/sublime-text/Installed Packages/LSP.sublime-package/plugin/core/sessions.py", line 1964, in on_payload
  File "/home/zeux/.config/sublime-text/Installed Packages/LSP.sublime-package/plugin/core/sessions.py", line 1952, in deduce_payload
TypeError: int() argument must be a string or a number, not 'NoneType'

    The Python code that errors is

            elif "id" in payload:
            response_id = int(payload["id"])

    I'm assuming that "id" is set to null in the JSON response... I'm going to try to bisect this but I wanted to file this first in case it's something obvious.

  • Support Studio plugin to infer instance hierarchy

    Support Studio plugin to infer instance hierarchy

    Luau-lsp does not recognize required modules defined in rbxms. However, the instance of the ModuleScript is still recognized by luau-lsp. I expect requires of ModuleScripts defined in .rbxms to work with luau-lsp, but I get type errors instead, shown below.

    I have two reasons for keeping certain modules inside the .rbxl. The first reason is that I do not want to see several hundred modules from Roblox in my VSCode project. The second reason is to easily allow non-coders in my team create projects to edit particular module scripts without Rojo overwriting their work.

    Here is an example project already setup with rbxm files: lsp_bug.zip The included .rbxl shows that the code is valid and works with Rojo.

  • Adding the extension to Open VSX Registry

    Adding the extension to Open VSX Registry

    Right now, the extension is only available on the Microsoft's VSCode extension marketplace, this makes the extension inaccessible to users using a different version of VSCode such as code-server or VSCodium. Right now the only workaround I could find was to download the extension package and then installing them manually.

    Perhaps add the extension to the Open VSX Registry?

  • Path for luau-lsp.types.definitionFiles doesn't work on Windows

    Path for luau-lsp.types.definitionFiles doesn't work on Windows

    I'm successfully using luau-lsp.types.definitionFiles on macOS to define my own types with an absolute path to a definition file. Unfortunately I can't get the same definitions to work on Windows though. On reload, luau-lsp simply says the definitions file does not exist.

    I'm pretty sure I've tried all combinations and permutations of forward slashes, backward slashes, double slashes, double quotes, etc. I've also tried both using the VSCode Settings UI and editing the json manually.

    I'm also sure the file exists at the path I'm providing! Not sure what else it could be.

  • Diagnostics do not cleared for ignored files

    Diagnostics do not cleared for ignored files

    I would like Luau-LSP to copy Roblox Studio's "Type Inference Modes" behavior documented here: https://luau-lang.org/typecheck#type-inference-modes

    This makes it easier to use other people's code that also uses these annotations without finding and changing ignore globs in vscode. I think this feature should be an optional setting in vscode to respect type inference modes annotation.

  • Doc comment support in type definitions

    Doc comment support in type definitions 

    export type Roact = {
	--[=[
		Creates a roact element.

		...
	]=]
	createElement: () -> (),
}

    This could be a potential solution to older libraries not having moonwave-style doc comments. A user could then make a wrapper package that exports proper types and documentation comments pulled from the original package.

    This is also a potential solution to classes that are difficult to add types to using the idiomatic export class Class = typeof(Class.new()) and that need a full type definitions to work well.

    Possibly related to #236 considering the above remarks

  • Don't enable all FFlags (related to recent crashing)

    Don't enable all FFlags (related to recent crashing)

    Currently the Language Server is heavily crashing due to a problem upstream in Luau (https://github.com/Roblox/luau/issues/780)

    The bug is gated behind the LuauUninhabitedSubAnything, but currently we enable all FFlags by default.

    To temporarily alleviate this bug, you can set the above FFlag to False, or disable the "Enable all FFlags" setting.

    We should in general make "Enable all FFlags" no longer on by default, as it is not necessary anymore with the FFlag syncing with Studio. There may be cases where this is disadvantageous though, so we will need to look into this further.

  • 1.7.0(Jul 17, 2022)

    [1.7.0] - 2022-07-16

    Added

    • Reintroduced support for workspace diagnostics, with proper streaming support. Enable luau-lsp.diagnostics.workspace for project wide diagnostics.
    • You can now hover over a type node to get type information. In particular, this works for properties inside type tables, and hovering over typeof(), allowing you to determine what typeof resolved to.
    • Added Go To Definition for type references
    • Added Luau: Regenerate Rojo Sourcemap command to force regeneration of a Rojo sourcemap
    • Improved case where project file default.project.json was not found. We search for other project files, and prompt a user to configure

    Changed

    • Sync to upstream Luau 0.536
    • Improved extension error message when Rojo version present does not have sourcemap support
    • Document links will now resolve for requires in all locations of a file, not just the top level block

    Fixed

    • A diagnostic refresh will now be requested once sourcemap contents change
    • With the introduction of workspace diagnostics, ignored files should now only show diagnostics when specifically opened
    • Document symbols for method definitions now correctly use a colon instead of a dot operator.
    • Fixed crash when hovering over a type node
    • Fixed go to definition on a global just going to the top of the file. It will now not accept go to definition requests
    • Fixed using absolute file paths to point to definition files not working on Windows

  • 1.6.0(Jul 2, 2022)

    [1.6.0] - 2022-07-02

    Added

    • Added luau-lsp.sourcemap.enabled option which dictates whether sourcemap-related features are enabled
    • Diagnostics will now be provided for definitions files which errored
    • Added luau-lsp.sourcemap.rojoPath to explicitly specify the path to a Rojo executable instead of relying on it being available from the workspace directory
    • Added hover information when hovering over a type definition

    Changed

    • Moved definitions file loading to post-initialization
    • Sync to upstream Luau 0.534
    • A _ will no longer show when we can't determine a function name / a function isn't named.

    Fixed

    • Fixed regression where diagnostics are not cleared when you close an ignored file
    • Fixed errors sometimes occuring when you index script/workspace/game for children
    • Fixed internal error caused by :Clone() calls when called on an expression which isn't an Lvalue (e.g., inst:FindFirstChild(name):Clone())
    • Fixed bug where _: would not be removed as the name of function arguments. function foo(_: number, _: number) will now show as function foo(number, number)
    • Fixed analyze mode not exiting with a non-zero exit code when there are errors
    • Fixed excessive whitespace in document symbols for expr-named function defintions
    • Fixed hover for global functions and local variables

  • 1.5.0(Jun 20, 2022)

    [1.5.0] - 2022-06-20

    Added

    • Added predicate logic to EnumItem:IsA("Type") so it will now narrow the type of an EnumItem when used as a predicate
    • Added setting to configure whether all Luau FFlags are enabled by default. This can be configured using luau-lsp.fflags.enableByDefault or --no-flags-enabled command line option. Currently, all FFlags are enabled by default, but you can manually sync/override them.
    • Added support for adding extra definition files to load using luau-lsp.types.definitionFiles
    • Roblox definitions can now be disabled using luau-lsp.types.roblox
    • Added label details to completion items

    Changed

    • Sync to upstream Luau 0.532
    • Updated to improve table type stringification, with an appropriate newline placed in between braces. This should result in better readable table types when hovering
    • Upgraded vscode language client to 8.0, with support for LSP Specification 3.17
    • VSCode Client now makes use of diagnostics pull model

    Fixed

    • Fixed equality comparison between enum items raising a type error
    • Fixed autocompletion of properties with spaces not correctly being converted into a ["property"] index leading to a type error
    • Fixed function stringification when using an expression index call such as data["property"]()
    • Fixed workspace diagnostics not respecting ignore globs for dependent files

    [1.4.0] - 2022-06-12

    Added

    • Added Document Symbols support
    • Merged luau-analyze-rojo into the project to simplify maintenance. To run a standalone analysis tool, run luau-lsp analyze
    • Added links to Luau Documentation for lint warnings
    • Added documentation to Enum types
    • Diagnostics of dependents (i.e., files which require a changed file) will now refresh to display type errors when the file changes
    • Added support for workspace-wide diagnostics to report in all files. You can enable this using luau-lsp.diagnostics.workspace. It is disabled by default

    Changed

    • Sync to upstream Luau 0.531
    • Unused lints will are now tagged appropriately so they render faded out

    Fixed

    • Fixed the equality comparison between two Instance types causing a type error
    • Fixed false positive type errors occuring when using DataModel instance types. Unfortunately, for this fix we had to temporarily type all DataModel instances as any. You should still get proper autocomplete and intellisense, however type errors will no longer throw for unknown children.
    • Fixed enum types to be under the "Enum" library, so the types are referenced using Enum.Font instead of EnumFont
    • HTML Tags have been stripped from documentation so they should render better in IntelliSense
    • Fixed "Text Document not loaded locally" error occuring when you start typing in a newly created file (as the sourcemap is not yet up-to-date)

    Added

    • Added support for configuring enabled Luau FFlags
    • Added support for pulling in the currently enabled FFlags in Studio, in order to replicate behaviour

    Changed

    • The "Updating API" message will now only show on the status bar instead of a popup notification.
    • Instance types will now be named by the Class Name rather than the Instance name
    • File system watchers for .luaurc and sourcemap.json are now registered on the server side

    Fixed

    • Fixed requiring modules when using :FindFirstAncestor("Ancestor")
    • Fixed requiring modules in LocalPlayer.PlayerGui / LocalPlayer.PlayerScripts / LocalPlayer.StarterGear
    • Changing .luaurc configuration will now refresh the config cache and update internally

    [1.2.0] - 2022-06-04

    Added

    • Player will now have PlayerGui, Backpack, StarterGear and PlayerScripts children, with the relevant Starter instances copied into it (StarterGui, StarterPack, PlayerScripts)
    • Instance:FindFirstChild("name") and Instance:FindFirstAncestor("name") will now correctly resolve to the relevant instance type if found. This allows the type checker to correctly resolve children/parents etc.

    Changed

    • Sync to upstream Luau 0.530

    Fixed

    • Fixed extension repeatedly downloading latest API information when it is already up to date
    • Fixed self: Type showing up in hover information/autocomplete when it is unnecessary at it has been inferred by the : operator
    • Fixed extension not displaying error if calling out to Rojo command fails
    • Fixed reverse dependencies not updating when types of required modules change (causing the type system to be incorrect). i.e., if you required script B in script A, and change script B, now the change will propagate to script A

    [1.1.0] - 2022-05-20

    Added

    • Can disable automatic sourcemap generation in extension settings.
    • Can change the project file used to generate sourcemap in extension settings (defaults to default.project.json).
    • Can toggle whether non-script instances are included in the generated sourcemap (included by default).
    • Added support for "Find References"
      • Currently only works for finding all references of a local variable in the current document. Cross-file references will come in future.
    • Added support for "Rename"
      • Currently only works for local variables in the current document. Cross-file references will come in future.

    Added

    • Added hover information for type references
    • Added end autocompletion functionality, as done in Studio. Can be enabled through luau-lsp.autocompleteEnd

    Changed

    • Improved Go To Type Definition support
    • Improved overall Go To Definition support
      • Can now handle function definitions in tables
      • Can handle cross-file definitions
      • Can handle deeply nested tables - multiple properties (incl. cross file support)
    • Hovering over a property inside a table will now give you type information about the assigned expression, rather than just "string"

    Fixed

    • Fixed syntax highlighting of generic type packs in function definitions

Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a viable target for a C compiler. It has a simplified instruction set compared to 'x86', but contains all the main ideas used in modern CPUs.
