Changelog

0.19.0

Added

• Added SPLIT_BEFORE_EXPRESSION_AFTER_OPENING_PAREN that enforces a split
  after the opening paren of an expression that's surrounded by parens.
  Changed
• Split before the ending bracket of a comma-terminated tuple / argument list
  if it's not a single element tuple / arg list.
  Fixed
• Prefer to split after a comma in an argument list rather than in the middle
  of an argument.
• A non-multiline string may have newlines if it contains continuation markers
  itself. Don't add a newline after the string when retaining the vertical
  space.
• Take into account the "async" keyword when determining if we must split
  before the first argument.
• Increase affinity for "atom" arguments in function calls. This helps prevent
  lists from being separated when they don't need to be.
• Don't place a dictionary argument on its own line if it's the last argument
  in the function call where that function is part of a builder-style call.
• Append the "var arg" type to a star in a star_expr.

0.18.0

Added

• Option ALLOW_SPLIT_BEFORE_DICT_VALUE allows a split before a value. If
  False, then it won't be split even if it goes over the column limit.
  Changed
• Use spaces around the '=' in a typed name argument to align with 3.6 syntax.
  Fixed
• Allow semicolons if the line is disabled.
• Fix issue where subsequent comments at decreasing levels of indentation
  were improperly aligned and/or caused output with invalid syntax.
• Fix issue where specifying a line range removed a needed line before a
  comment.
• Fix spacing between unary operators if one is 'not'.
• Indent the dictionary value correctly if there's a multi-line key.
• Don't remove needed spacing before a comment in a dict when in "chromium"
  style.
• Increase indent for continuation line with same indent as next logical line
  with 'async with' statement.

0.17.0

Added

• Option NO_SPACES_AROUND_SELECTED_BINARY_OPERATORS prevents adding spaces
  around selected binary operators, in accordance with the current style guide.
  Changed
• Adjust blank lines on formatting boundaries when using the --lines option.
• Return 1 if a diff changed the code. This is in line with how GNU diff acts.
• Add -vv flag to print out file names as they are processed
  Fixed
• Corrected how DEDENT_CLOSING_BRACKETS and COALESCE_BRACKETS interacted.
• Fix return value to return a boolean.
• Correct vim plugin not to clobber edited code if yapf returns an error.
• Ensured comma-terminated tuples with multiple elements are split onto separate lines.

0.16.3

Changed

• Add filename information to a ParseError excetion.
  Fixed
• A token that ends in a continuation marker may have more than one newline in
  it, thus changing its "lineno" value. This can happen if multiple
  continuation markers are used with no intervening tokens. Adjust the line
  number to account for the lines covered by those markers.
• Make sure to split after a comment even for "pseudo" parentheses.
