Fixed

Full Changelog: v0.11.2...v0.11.3

v0.11.2

[0.11.2] - 2021-11-15

Fixed

• Fixed spaces around brackets string ([[string]]) used as an index or table key (i.e. [ [[string]] ]) being removed, leading to a syntax error. (#293)
• Fixed incorrect shape calculation leading to arguments incorrectly expanding when under column width. (#298)
• Fixed incorrect shape calculation for singleline table at the column width boundary. (#296)
• Fixed IfExpression syntax containing extra/abnormal trailing whitespace when currently formatting as-is under the luau feature flag. (#297)
• Fixed newlines before arguments in a function call which is later formatted on a single line being preserved, leading to inconsistent formatting. (#290)
• Fixed odd formatting when returning multiple tables or functions only. (#302)
• Fixed comments within an index expression (foo[index]) incorrectly handled leading to malformed formatting. (#304)

v0.11.1

[0.11.1] - 2021-11-08

Changed

• Updated internal parser to fix parsing issues and update luau parsing. (#229, #231)
• Default glob now matches **/*.luau (as well as **/*.lua) when the luau flag is enabled. (#291)

Fixed

• Fixed indentation of type callback specifier parameters when parameters have leading comment trivia. (#278)
• Fixed trailing comma not being taken into account when determining the width of a field in a multiline table. (#282)
• Fixed --num-threads 1 causing a deadlock. (#281)
• Fixed whitespace around parts of a binary expression causing it to over-hang in first pass, leading to unstable formatting. (#287)

v0.11.0

[0.11.0] - 2021-09-16

Changed

• In Luau type tables, a newline after the opening brace will now force the type table multiline. This is the same procedure as standard tables. (#226)
• In Luau, type specifiers for function parameters will now force the parameters to be formatted multiline if a specifier is multiline (and there is more than one parameter).
• Improved error messages to make them easier to understand.

Fixed

• Fixed range formatting no longer working when setting the range to statements inside nested blocks. (#239)
• Fixed ignore file present in cwd not taken into account if cwd not included in file paths to format. (#249)
• Fixed config locations ($XDG_CONFIG_HOME and $HOME/.config) not being looked into correctly on macOS when --search-parent-directories is used. (#260)
• Fixed incorrect indentation of multiline type specifiers for function parameters under the luau feature flag. (#256)
• Fixed unstable formatting caused by a singleline table which just reaches the column width. (#261)
• Fixed misformatting of a binop expression as precedence of the RHS expression was not taken into account. (#257, #261)

v0.10.1

[0.10.1] - 2021-08-08

Fixed

• Fixed an incorrect trailing comma being added to function args as part of a multiline expression list leading to a syntax error. (#227)
• Fixed the first expression in a multiple assignment prematurely hanging even if its below the column width. (#233)
• Updated internal parser to fix parsing issues for Luau code under the luau feature flag.

v0.10.0

[0.10.0] - 2021-07-11

Added

• Added flag --verify which, when enabled, attempts to verify the generated output AST with the input AST to detect any changes to code correctness. Useful for adopting StyLua into a large codebase, at the cost of slower processing. (#199)
• Added optional command line options --column-width, --indent-type, --indent-width, --line-endings and --quote-style, which, when provided, will override any configuration setting inferred from the default or a stylua.toml. (#213)
• Added multithreaded support for formatting file in the CLI. Now each file will be formatted in its own thread. The number of threads used defaults to the number of cores on your computer, but can be set using --num-threads
• Added support for disabling formatting over specific ranges. Use -- stylua: ignore start to disable formatting and -- stylua: ignore end to re-enable it. The comment must be preceding a statement and disabling formatting cannot cross block scope boundaries. (#198)

Changed

• Luau type tables (luau feature flag) now use the same formatting strategy as normal expression tables, so that their formatting is more aligned.
• Luau typings now have improved checking against the current shape width to determine how to format if over column width.
• Luau callback types will now format multiline if they become over width under the luau feature flag.
• Improved the formatting of return expressions, they are now more in line with assignment expressions. (#194)
• Changed buffering of error messages in the CLI. Originally, they would be buffered till the end, but now they are output immediately when seen.
• Allowed the use of --check when taking input from stdin.
• An error when parsing provided globs will cause the program to immediately exit rather than continuing with the incorrect glob.
• Only diff errors will exit with a status code of 1. Other errors (e.g. parse errors or internal errors) will now exit with status code of 2.

Fixed

• Fixed comments inside Luau type tables leading to malformed formatting under the luau feature flag. (#219)
• Fixed multiple assignment where an expression was originally hung due to comments being collapsed leading to malformed formatting. (#222)
• Fixed an issue where a function call with a single table argument being hugged with the parentheses which contain comments leading to a syntax error. (#224)

v0.9.3

[0.9.3] - 2021-06-26

Added

• Added --verbose to print debug information, including finding config files and time taken to format files.

Fixed

• Fixed severe performance regression due to a change in table formatting leading to exponential blowup for nested tables. (#205)
• Fixed long binop chains with a comment deep inside not being hung, leading to a syntax error. (#210)
