- Added configuration luau-lsp.bytecode.vectorLib, luau-lsp.bytecode.vectorCtor and luau-lsp.bytecode.vectorType to configure compiler options when generating bytecode
- Custom editors should handle the luau-lsp/bytecode and luau-lsp/compilerRemarks LSP message to integrate compiler remarks info in their editor

Changed

Sync to upstream Luau 0.607
Made rename operation fully backed by find all references, to ensure both return results that are consistent with each other
Hide return type hints for no-op functions
Changed the VSCode registered language and grammar ID from lua to luau. **NOTE: ** this may affect existing custom themes!
Renamed script/globalTypes.d.lua to script/globalTypes.d.luau (the old file will be kept temporarily for compatibility)
Default security level of API types changed from RobloxScriptSecurity to PluginSecurity - set luau-lsp.types.robloxSecurityLevel to RobloxScriptSecurity to see original behaviour
Improved warning message when Rojo not found when attempting to generate sourcemap, with option to configure settings to disable autogeneration

Fixed

Fixed Find All References / Rename not working on a table property defined inline, such as name in:

local T = {
  name = "string"
}

Fixed methods and events showing up in "GetPropertyChangedSignal" autocomplete
Fixed requiring a directory containing "init.lua" not working
Fixed go to definition on a property of a table that stores a cross-module type value (e.g. the result of a function defined in another module)

[1.26.0] - 2023-11-19

Added

Added support for documentation comments on table type properties:

type Foo = {
  --- A documentation comment
  map: () -> ()
}

We now show the file path in the completion description when auto-requiring files

Changed

Sync to upstream Luau 0.604
Overhauled command line argument parsing system to be more consistent and flexible
Deprioritized loadstring in autocomplete
luau-lsp.diagnostics.strictDatamodelTypes now defaults to false on the language server side (note, it was already default false in VSCode). Defaulting to true was unintentional. This will affect external language client users (e.g. neovim)
Analyze CLI tool now respects luau-lsp.diagnostics.strictDatamodelTypes if set in the provided configuration. The flag --no-strict-dm-types still remains for backwards compatibility reasons, but is now deprecated.

Fixed

Attempting to rename a generic type parameter now correctly renames it in all locations
Fixed renaming a local variable not appropriately renaming any imported types
Auto-import requires will now show the full codeblock that will be inserted, rather than just the first line if also inserting a service

[1.25.0] - 2023-10-14

Changed

Sync to upstream Luau 0.599
Prioritise game:GetService() as the first autocompletion entry when typing game:
Code blocks in hover and documentation now use luau as the syntax highlighting

Fixed

Do not add line separator in hover when there is no text documentation
Fixed init files not working with directory aliases (e.g. require("@dir") or require("@dir/subdir"))

[1.24.1] - 2023-09-09

Changed

Sync to upstream Luau 0.594
Support autocomplete end on do blocks

Fixed

Fixed crash when attempting to Go To Definition of an imported type

[1.24.0] - 2023-08-26

Changed

Sync to upstream Luau 0.592
Simplified Instance.new and game:GetService calls internally and in the definitions file to reduce complexity issues in the typechecker.

Fixed

Fixed cleanup of rojo sourcemap generation process when VSCode exits
Fixed color presentations values being unclamped causing errors in other editors
Fixed newline not added to separate services and requires when the suggestion imports both at the same time

[1.23.0] - 2023-08-06

Added

Added command luau-lsp.reloadServer to restart the language server without having to reload the workspace

Changed

Sync to upstream Luau 0.589
Changes to settings which require server restart will now reload the server instead of having to reload the whole VSCode workspace
Switch to Rojo rojo sourcemap --watch command for sourcemap autogeneration. Note that on rojo error, you must manually restart sourcemap regeneration. Requires Rojo v7.3.0+

Fixed

Reverted change to type checking in 1.22.0 that reduced memory footprint. This should resolve the problems where diagnostics aren't showing with an InternalCompilerError, at the cost of increased memory use if luau-lsp.diagnostics.workspace is enabled.
Fixed string require resolution when the string had a secondary extension: Module.mod will be resolved as Module.mod.luau
Fixed resolution of directory aliases pointing to relative paths

[1.22.1] - 2023-07-15

Changed

Sync to upstream Luau 0.584
Removed need for typechecking for operations that don't require the type information (e.g., document link / color)

Fixed

Fixed diagnostics not showing when working in a new file with no workspace open
Fixed race condition where sometimes the server does not receive user configuration on initial load, falling back to defaults
luau-lsp.fflags.override will now be parsed when using CLI analyze settings. Note that the other fflags options are not supported in CLI analyze mode
Fixed semantic tokens segfault crash on some tables
Fixed duplicate definitions showing in the Go To Definition page
Fixed some syntax highlighting inconsistencies
Added a temporary fix to "RecursionLimitException" exceptions leaking to the public interface.

[1.22.0] - 2023-06-30

Added

Support requiring directories with init.luau (or init.lua) files inside of them. i.e. require("../Directory") resolves to ../Directory/init.luau.
The CLI analyze now accepts a parameter --settings=path/to/settings.json which takes in LSP-style settings to configure features such as require settings. Note: this is separate to .luaurc

Changed

Significant improvements to memory usage in large workspaces when workspace indexing or diagnostics are enabled
Sync to upstream Luau 0.582
Deprioritise file or directory aliases over exact paths in autocomplete, since typically aliases start with a prefix (e.g. @)
Signature Help is more intelligent about providing information about the best function overload which matches

Fixed

Fixed language features not working in new untitled files
Fixed incorrect color conversions in the color picker between RGB/HSV/Hex
Fixed autoimporting modules not respecting multiline requires
Fixed documentation for debug and utf8 library
Fixed synthetic typeof() showing up in signature help for builtin tables (e.g. function typeof(string).byte(...))
Fixed signature help highlighting for string library
Fixed rename symbol on a type definition type NAME = ...
Fixed file and directory aliases not being canonicalised to absolute paths causing "Follow Link" to fail when using relative alias paths

Fix indentation of autocomplete end when autocompleting inside of a function call

[1.21.0] - 2023-06-14

Deprecated

Deprecated luau-lsp.autocompleteEnd setting in favour of luau-lsp.completion.autocompleteEnd

Added

Added folding ranges for multi-line function definitions, so long parameter lists can be collapsed
Added notification when we detect definitions file changes
Added support for auto-requiring modules when autocompleteing a type reference, to allow indexed types: i.e. autocompleting Module in type Foo = Module.Bar
Added luau-lsp.require.directoryAliases to map require string prefixes to directories
Added tilde expansion to luau-lsp.require.fileAliases (and directoryAliases), mapping ~/foo.lua to a file in your home directory
End autocompletion will now work for defined anonymous functions inside of function calls

Changed

Sync to upstream Luau 0.580
Updated workspace indexing strategy to minimise memory usage. We no longer index ignored files (luau-lsp.ignoreGlobs), and there is a setting luau-lsp.index.maxFiles (default: 10,000) to configure the amount of files indexed before backing off.

Fixed

When editing in model projects, we now force relative requires, instead of incorrect absolute requires using a "ProjectRoot"

[1.20.2] - 2023-05-10

Fixed

Fixed internal error for LazyType unwrapping

[1.20.1] - 2023-05-09

Fixed

Fixed bug in semantic tokens system causing language server crashes

[1.20.0] - 2023-05-09

Added

Added support for workspace symbols to resolve symbols across the whole workspace. In VSCode, you can open this using Ctrl + T
Added configuration option luau-lsp.require.fileAliases to statically provide custom mappings from string requires to a file path. For example, adding @example/constants mapping to C:/fakepath/constants.luau will automatically resolve require("@example/constants")
Added support for Folding Ranges. The language server now signals the following foldable ranges in a document:
- Whole blocks, such as do .. end, for - do .. end function() .. end etc.
- Tables, and type tables x = { .. }
- Multiline function calls foo(..)
- Block comments --[[ .. ]]
- Custom comment regions denoted using --#region and --#endregion
Added support for Call Hierarchies. Call Hierarchies allow you to view all incoming and outgoing calls of a function: i.e., all functions that call the current function, as well as all functions that the current function calls. This works at multiple levels, displaying ancestor and descendant functions.

Changed

Sync to upstream Luau 0.575

[1.19.2]

Fixed

Fixed forced expressive types in diagnostics
Added option --no-strict-dm-types for analyze CLI to disable strict datamodel types and its associated false positives

[1.19.1] - 2023-04-27

Fixed

Fixed regression in DataModel item autocompletion

[1.19.0] - 2023-04-26

Deprecated

Deprecated config luau-lsp.completion.suggestImports: use luau-lsp.completion.imports.enabled instead

Added

Added setting luau-lsp.index.enabled which will index the whole workspace into memory. If disabled, only limited support for Find All References and rename is possible
Added support for finding all references of both local and exported types. For exported types, luau-lsp.index.enabled must be enabled for full support.
Added support for renaming table properties across files. If luau-lsp.index.enabled is disabled, this feature is disabled for correctness reasons.
Added support for renaming types (both local and exported). If luau-lsp.index.enabled is disabled, this exported types renaming is disabled for correctness reasons.
Added more settings to auto-importing:
- luau-lsp.completion.imports.enabled: replaces luau-lsp.completion.suggestImports (default: false)
- luau-lsp.completion.imports.suggestServices: whether GetService imports are included in suggestions (default: true)
- luau-lsp.completion.imports.suggestRequires: whether auto-requires are included in suggestions (default: true)
- luau-lsp.completion.imports.requireStyle: the style of require format (default: "auto")
- luau-lsp.completion.imports.separateGroupsWithLine: whether an empty line should be added in between services and requires (default: false)

Changed

Sync to upstream Luau 0.573
Improved find all references system for tables. We can now track all references to table and its properties across files. This requires luau-lsp.index.enabled to be enabled for full support.

Fixed

Fixed pull diagnostics result not following spec
Fixed errors when file has shebang #! present at top of file
Fixed string require autocompletion failing when autocomplete triggered on an incomplete string, e.g. require("Constants/Te|"). Originally, nothing would autocomplete. Now, everything inside of the Constants folder will still autocomplete as usual (filtered for "Te").

[1.18.1] - 2023-03-23

Fixed

Fixed server crash when auto require imports is enabled and there is a type-asserted require present in the file (require(location) :: any)
Fixed additional automatic service imports when completing an automatic require import being placed before a hot comment (such as --!strict)
Fixed automatic require import being placed incorrectly we also autocomplete a service. This can be shown when there is a multiline comment, and the service is imported above that comment, but the require gets imported inside of the comment incorrectly.

[1.18.0] - 2023-03-20

Added

Added support for changing Color3 colors using the color picker
Added support for automatic require imports (currently only for Roblox mode). If you start typing the name of a module in your code, you can autocomplete the require statement automatically. This feature is enabled by setting luau-lsp.completion.suggestImports.

Changed

Sync to upstream Luau 0.568. In particular, this provide improvements to control flow analysis refinements. This allows the type checker to recognise type options that are unreachable after a conditional/unconditional code block. e.g.:

local function x(x: string?)
    if not x then return end

    -- x is 'string' here
end

To enable this feature, the FFlag LuauTinyControlFlowAnalysis must currently be enabled.

The language server will only be enabled on "file" and "untitled" schemes. This means it will be disabled in diff mode and live share. This is because we cannot yet provide sufficient information in these contexts.

[1.17.1] - 2023-03-04

Changed

Sync to upstream Luau 0.566

Fixed

Don't autocomplete another set of parentheses on a function call if they already exist
Fix .luaurc in current working directory not taken into account when calling luau-lsp analyze

[1.17.0] - 2023-02-12

Added

Added two code actions: Sort requires and Sort services (services only enabled if luau-lsp.types.roblox == true). These actions will sort their respective groups alphabetically based on a variable name set. You can also set these actions to automatically run on save by configuring:

"editor.codeActionsOnSave": {
"source.organizeImports": true
}

Changed

Sync to upstream Luau 0.563
Prioritised common services and Instance properties/methods in autocomplete so that they show up first

Fixed

Further fixes to document symbols failing due to malformed ranges

[1.16.4] - 2023-02-10

Fixed

Fixed document symbols crashing due to internal malformed data

[1.16.3] - 2023-02-09

Fixed

Changed internal representation of documents to reduce the likelihood of Request Failed for "No managed text document"

[1.16.2] - 2023-02-01

Fixed

Fixed document symbol crash on incomplete functions
Fixed --base-luaurc not registering for an LSP server
Fixed crashing on invalid FFlags configuration - the VSCode client will now validate the flags

[1.16.1] - 2023-01-30

Fixed

Fixed error in document symbols not conforming to specification - selectionRange will now be fully enclosed by range

[1.16.0] - 2023-01-29

Added

Support documentation comments attached to a table and table types, e.g. on DATA in the followign:

--- Doc comment
local DATA = {
    ...
}

--- Doc comment
type Contents = {
	...
}

Include documentation comments on functions and tables in autocompletion
Added configuration option luau-lsp.require.mode to configure how string requires are resolved. It can either be relativeToWorkspaceRoot (default) or relativeToFile
Added luau-lsp.types.documentationFiles to support adding extra documentation symbols to the database. These are used to support definition files, and should be in the same format as shown here
Added luau-lsp.diagnostics.strictDatamodelTypes (default: false) which configures whether we use expressive DataModel types to power diagnostics. When off, game / script / workspace (and all their members) are typed as any, which helps to prevent false positives, but may lead to false negatives.
Added CLI option --base-luaurc=PATH for both LSP and Analyze mode to provide a path to a .luaurc file which is used as the default configuration
Added support for Go To Definition / Type Definition on imported type references module.Type (gated behind FFlag SupportTypeAliasGoToDeclaration)

Changed

Sync to upstream Luau 0.560
Class symbols with no documentation present in the docs file will no longer show anything on hover/autocomplete (i.e. won't show @luau/global/require)
Instance.new() now excepts variables which are of type string without erroring. It will instead error when Instance.new is called with a string literal which is an unknown class name
In the CLI, luau-lsp lsp now supports passing multiple --docs= parameters
The CLI will now error when an unknown option is passed to it
Diagnostics will now be emitted on .luaurc files with parse errors

Fixed

Fixed unknown require errors occurring in multi-root workspaces when in a folder which isn't the first one
Fixed diagnostics not clearing for files which were deleted unconventionally (i.e., outside of VSCode using File Explorer, or external commands such as git stash)

[1.15.0] - 2023-01-11

Added

Added syntax highlighting support for interpolated strings
Added color viewers for Color3.new/fromRGB/fromHSV/fromHex
Added support for autocompleting require-by-string functions with files and folders
Support documentation comments on variables:

--- documentation comment
local x = "string"

--- another doc comment
local y = function()
end

Support documentation comments on table properties, such as the following:

local tbl = {
    --- This is some special information
    data = "hello",
    --- This is a doc comment
    values = function()
    end,
}

local x = tbl.values -- Should give "This is a doc comment"
local y = tbl.data -- Should give "This is some special information"

Changed

Sync to upstream Luau 0.558
All Luau FFlags are no longer enabled by default. This can be re-enabled by configuring luau-lsp.fflags.enableByDefault. It is recommended to keep luau-lsp.fflags.sync enabled so that FFlags sync with upstream Luau
Allow variable number of = sign for multiline doc comments, so --[[ and --[===[ etc. are valid openers

Fixed

Luau analyze now exits with code 0 if there are no reported errors (all errors are ignored)
require(instance:FindFirstChild("Testing", true)) will no longer resolve as an immediate child of instance due to the recursive argument
Fixed a bug where internally the wrong pointer to an Instance type was being used for DM nodes which manifested into failed unification and never types
Constant variables will now be syntax highlighted appropriately at definition site (local CONSTANT)

Fixed Request Failed due to "No managed text document" as URLs were not being updated correctly

[1.13.0] - 2022-10-28

Added

Show documentation for overloaded functions in completion and hover. We show the documentation string of the first overload, and how many other overloads are present.
Show documentation for builtin class methods in signature help, including for the correct overload
Show documentation for parameters in signature help
Added luau-lsp.completion.addParentheses and luau-lsp.completion.addTabstopAfterParentheses to configure whether parentheses are added when completing a function call, and whether we include a tab stop after the parentheses respectively.
Automatically fill function call arguments using parameter names. This can be disabled using luau-lsp.completion.fillCallArguments.

Changed

Sync to upstream Luau 0.551
Hide parameter name and variable inlay hint if the name is just _

Fixed

Fixed string-based requires to use a fully-qualified file path, fixing Document Link (Follow Link) support for requires

Fixed diagnostics not showing for any file after the first one you open

[1.5.1] - 2022-06-21

Fixed

Module name will now be included in hover and signature displays for imported types
Fixed bug where in-memory contents of a document which was deleted were not cleared, causing spurious errors when recreating a new document of the same name.
Fixed duplicate diagnostics displayed and never clearing when workspace diagnostics configuration was enabled

[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

[1.4.0] - 2022-06-12

Added

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)

[1.3.0] - 2022-06-10

Added

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).

- Currently only works for local variables in the current document. Cross-file references will come in future.

Changed

Sync to upstream Luau 0.528

Added

Added hover information for type references

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

[0.4.1] - 2022-05-17

Added

Added basic go to definition and go to type definition support
Added support for pull-based diagnostics
Added the base support for user configuration through extension settings

Cross compiled macOS binary to arm64

Changed

Hover over definitions will now try to give more expressive types
self will now no longer show up in hover/signature help if it has already been implicitly provided
