Release Notes

pytest-dev/iniconfig (iniconfig)

v2.3.1

Compare Source

=====

• fix quadratic parse time for values with many continuation lines (#​78, regarding #​77)
• strip a leading UTF-8 BOM when reading INI files, which previously raised ParseError (#​76)
• internal: iniconfig._parse.ParsedLine.value is now a list of lines

v2.3.0

Compare Source

=====

• add IniConfig.parse() classmethod with strip_inline_comments parameter (fixes #​55)
  • by default (strip_inline_comments=True), inline comments are properly stripped from values
  • set strip_inline_comments=False to preserve old behavior if needed
• IniConfig() constructor maintains backward compatibility (does not strip inline comments)
• users should migrate to IniConfig.parse() for correct comment handling
• add strip_section_whitespace parameter to IniConfig.parse() (regarding #​4)
  • opt-in parameter to strip Unicode whitespace from section names
  • when True, strips Unicode whitespace (U+00A0, U+2000, U+3000, etc.) from section names
  • when False (default), preserves existing behavior for backward compatibility
• clarify Unicode whitespace handling (regarding #​4)
  • since iniconfig 2.0.0 (Python 3 only), all strings are Unicode by default
  • Python 3's str.strip() has handled Unicode whitespace since Python 3.0 (2008)
  • iniconfig automatically benefits from this in all supported versions (Python >= 3.10)
  • key names and values have Unicode whitespace properly stripped using Python's built-in methods
