This is meant as an adoption helper, avoid using this for new projects. +As an experimental option, _Black_ splits long strings (using parentheses where +appropriate) and merges short ones. When split, parts of f-strings that don't need +formatting are converted to plain strings. User-made splits are respected when they do +not exceed the line length limit. Line continuation backslashes are converted into +parenthesized strings. Unnecessary parentheses are stripped. To enable experimental +string processing, pass `--experimental-string-processing` on the command line. Because +the functionality is experimental, feedback and issue reports are highly encouraged! + +_Black_ also processes docstrings. Firstly the indentation of docstrings is corrected +for both quotations and the text within, although relative indentation in the text is +preserved. Superfluous trailing whitespace on each line and unnecessary new lines at the +end of the docstring are removed. All leading tabs are converted to spaces, but tabs +inside text are preserved. Whitespace leading and trailing one-line docstrings is +removed. The quotations of an empty docstring are separated with one space. + ### Numeric literals _Black_ standardizes most numeric literals to use lowercase letters for the syntactic diff --git a/tests/data/docstring.py b/tests/data/docstring.py index 74532b2..9e1c244 100644 --- a/tests/data/docstring.py +++ b/tests/data/docstring.py @@ -115,6 +115,10 @@ def oneline_empty(): ''' ''' +def oneline_nothing(): + """""" + + def single_quotes(): 'testing' @@ -267,6 +271,10 @@ def oneline_empty(): """ """ +def oneline_nothing(): + """ """ + + def single_quotes(): "testing"
