Hints & Hover Settings - GLua Language Server

Overview

These settings control editor hints, hover documentation, and semantic syntax highlighting.

Inlay hints (`hint.*`)

Inlay hints show inline type and name annotations beside your code.

Option	Type	Default	Description
`hint.paramHint`	`boolean`	`true`	Show parameter names next to call arguments
`hint.localHint`	`boolean`	`true`	Show inferred types next to local variable declarations
`hint.indexHint`	`boolean`	`true`	Show named indexes for array table entries
`hint.overrideHint`	`boolean`	`true`	Show which base-class method a function overrides
`hint.metaCallHint`	`boolean`	`true`	Show `__call` metamethod hints
`hint.enumParamHint`	`boolean`	`false`	Show enum member names next to literal integer arguments
`hint.closingEndHint`	`boolean`	`true`	Show `-- end FunctionName` hints after closing `end` keywords
`hint.closingEndHintControlFlow`	`boolean`	`false`	Also show closing end hints for `if`, `while`, `do`, `for` blocks
`hint.closingEndHintMinLines`	`integer`	`15`	Minimum number of lines a block must span before a closing hint appears

Inlay hint examples

Parameter hints:

Entity:SetPos(vec3(0, 0, 0))
--           ^ pos: Vector

Local hints:

local ply = game.GetWorld()
--    ^ : Entity

Closing end hints:

function GAMEMODE:PlayerSpawn(ply)
    -- ... 15 lines of code ...
end -- PlayerSpawn

Inline values (`inlineValues.*`)

Inline values show variable contents during a debug session, overlaid on the source code.

Option	Type	Default	Description
`inlineValues.enable`	`boolean`	`true`	Show variable values inline during debugging

Hover (`hover.*`)

Option	Type	Default	Description
`hover.enable`	`boolean`	`true`	Enable hover documentation

Hover documentation shows:

Type signatures and docs for functions, fields, and classes
Realm badge (client/shared/server) for GMod API symbols
@deprecated messages for deprecated symbols
@see cross-references
Inline +/− verbosity buttons for classes with many members — click + to show more members, − to show fewer

Semantic tokens (`semanticTokens.*`)

Semantic tokens provide syntax highlighting based on type analysis. GLuaLS colors variables by role, such as local, global, field, or method, instead of lexical category.

Option	Type	Default	Description
`semanticTokens.enable`	`boolean`	`true`	Enable semantic syntax highlighting
`semanticTokens.renderDocumentationMarkup`	`boolean`	`true`	Render Markdown in annotation documentation (e.g., in hover popups)

Code lens (`codeLens.*`)

Option	Type	Default	Description
`codeLens.enable`	`boolean`	`true`	Enable code lens actions (references, override links, VGUI parent links)

Code action (`codeAction.*`)

Option	Type	Default	Description
`codeAction.insertSpace`	`boolean`	`false`	Add a space after `---` when inserting `@diagnostic disable-next-line` via a code action

VS Code extension settings

You can also configure these settings in VS Code settings with the gluals.* prefix:

`gluals.inlineValues.enable`	`inlineValues.enable`	`boolean`	`true`	Inline debug values
`gluals.hover.enable`	`hover.enable`	`boolean`	`true`	Enable hover documentation
`gluals.semanticTokens.enable`	`semanticTokens.enable`	`boolean`	`true`	Enable semantic tokens

`gluals.documentColor.enable`	`documentColor.enable`	`boolean`	`true`	Color picker for color strings
