v0.14.0

[0.14.0] - 2022-07-06

Added

• --output-format=json now outputs all (error) messages in JSON format (#453)
• Added WASM build support. Stylua is available on npm for consumption in Node.js or a browser (using a bundler) - https://www.npmjs.com/package/@johnnymorganz/stylua
• Ignore comments will now be respected before fields inside tables (#448)
• Stylua library (stylua_lib) now exposes a format_ast(ast, config, range, verification) function to format a full-moon AST directly (#482)
• Added collapse_simple_statement option. It can take the values Never (default), FunctionOnly, ConditionalOnly or Always. When enabled, "simple" functions or if statements (ones where they only return a value or have a simple statement such as a function call) will be collapsed onto a single line where possible.

Changed

• We now attempt to first hang the equals token in an assignment before expanding the RHS expression, provided the expression is not "complex" (#292, #489)
• We now use the current indent level of comments preceding an elseif/else token to determine whether they should still be indented one level or inlined with the elseif/else token. (#254)
• Static chained function calls (i.e., foo.bar().baz()) will now hang if necessary (#368)
• The first call in a chained function call will now inline with the prefix if the prefix begins with an uppercase letter or the prefix is smaller (in length) than the indent width
• A chained function call will not expand if the first call gets inlined and there is only 2 calls

Fixed

• [Luau] Fixed spacing lost before a comment within a type generic (#446)
• [Luau] Removed unnecessary expansion of a type generic with a single table as the parameter (#442)
• Fixed incorrect extra indentation of an expanded parentheses passed as a function call argument (#456)
• [Luau] Increased the shape size of the expression in a type assertion so that it will correctly hang if over width (#466)
• Fixed binary expression in a table field containing a comment being collapsed leading to malformed formatted (#471)
• Fixed end parentheses of a function call with a multiline comment internally being expanded onto a new line unnecessarily (#473)
• Fixed severe performance regression with complex nested function calls (#477)

v0.13.0

NOTE: This release removes the version from the release file names (#343). If you have automated tooling to download StyLua releases, you may need to update them to exclude the version from the name

[0.13.0] - 2022-03-31

Added

General

• Added support for alternative diff outputs. You can now use --output-format=unified or --output-format=json to output a unified diff or json mismatches list respectively.

Changed

General

• Generic fors will no longer expand onto multiple lines if the expression looping over is a function call with a single table argument (e.g., ipairs({ ... })) (#405)
