lua.format.lineWidth (Default: 120)

Maximum length of a line before it will be wrapped.

lua.format.indentCount (Default: 4)

Number of characters to indent.

lua.format.singleQuote (Default: false)

Whether to use single or double quotes on strings. Defaults to double quotes.

lua.linting.enabled (Default: true)

Specifies whether to enable linting of source files

Luacheck

Support for linting is provided via luacheck. Installation instructions can be found on the luacheck repository.

Once installed, luacheck support can be activated by assigning the lua.luacheckPath setting to the path of the luacheck executable. Additionally, since luacheck provides vastly more detailed and contextually aware errors that may sometimes duplicate those created by luaparse, the setting lua.preferLuaCheckErrors can be set to true to suppress luaparse errors.
