Release Notes

LuaLS/lua-language-server (lua-language-server)

v3.19.1

Compare Source

2026-08-14

• NEW LuaJIT 3.0 extension syntax can now also be enabled individually via Lua.runtime.nonstandardSymbol (?., ??, ternary, ~>>, ~>>=, ..=, ~=, const, ->, number_underscore), independent of Lua.runtime.version and without the Lua.runtime.enableLuaJITExtensions master switch. Note that ~= enables the bitwise-xor compound assignment only in statement context (e.g. a ~= b on its own line).
• NEW Add no-dot optional chaining f?() and t?[1] (equivalent to f?.() / t?.[1]) as new Lua.runtime.nonstandardSymbol entries (?( and ?[), and the no-dot safe method obj?:get() (equivalent to obj?.:get(), entry ?:). Note: enabling ?( / ?[ together with the ternary (ternary) may conflict during parsing.
• NEW Support type inference for dofile and add a new Lua.workspace.dofileRoots setting to configure where it reads from #​3432

v3.19.0

• NEW Support LuaJIT 3.0 extension syntax when Lua.runtime.version is LuaJIT and the new Lua.runtime.enableLuaJITExtensions setting is enabled: ternary conditional ?:, safe navigation ?. (including method forms obj?.:method, obj:method?.), nil-coalescing ??, arithmetic shift ~>> with ~>>= compound assignment, ..= concatenation assignment, const declarations, short function expressions (x -> expr, |x| -> expr, -> do ... end), and number underscores (1_000) #​3434
• NEW @operator declarations on generic classes now resolve class type parameters through the instantiated type: with ---@class Box<T> and ---@operator call(): T?, calling a Box<string> instance infers string?
• NEW Support type inference for @field and @type function declarations in method overrides #​3367
• FIX Fix invalid LSP responses in files containing string literals with escaped bytes.
• FIX Fix method-level generic return type being overwritten by receiver class generic resolution #​3438
• FIX Generic type parameters used in @operator annotations are now recognized as generics (and highlighted as such) instead of being treated as undefined type names
• FIX Infer pcall/xpcall second result from their own declaration when the called function returns nothing #​3440
• FIX Recognize a class inheriting a generic class as a child of that generic's own parent #​3441
• FIX Deduplicate documentation bindings for parameters
• FIX Correct math.type meta return annotation to use nil instead of the string literal 'nil'
• FIX Fix initial nameStyle.config not getting loaded in the appropriate workspace.
