From ecbed7f03e3a1ffca7081ab48721bdf6eda4cf22 Mon Sep 17 00:00:00 2001 From: Jaysheel Dodia Date: Wed, 1 Oct 2025 01:04:40 -0400 Subject: [PATCH 1/2] feat(patterns): improve handling of field and section lists for mixed-style docstrings Improve handling of field and section lists for mixed-style docstrings - Refactor field list detection to preserve Google/NumPy sections when using Sphinx/Epytext styles. - Update list pattern recognition to distinguish between field-based and section-based styles. - Ensure only the appropriate sections are wrapped, preserving formatting for others. - Update description splitting logic to wrap only the description before a preserved section. - Add force_wrap shortcut to always wrap as regular text. - Update test data to reflect new logic (NumPy sections in Sphinx-style docs are now preserved). - Improves compliance with requirements for mixed-style docstrings and prevents unwanted wrapping. --- src/docformatter/patterns/fields.py | 34 +++++++++++++- src/docformatter/patterns/lists.py | 46 ++++++++++++++----- src/docformatter/strings.py | 22 ++++++++- src/docformatter/wrappers/description.py | 7 +++ .../string_files/description_wrappers.toml | 3 +- tests/_data/string_files/list_patterns.toml | 2 +- 6 files changed, 98 insertions(+), 16 deletions(-) diff --git a/src/docformatter/patterns/fields.py b/src/docformatter/patterns/fields.py index 4712e22..b7ed0a4 100644 --- a/src/docformatter/patterns/fields.py +++ b/src/docformatter/patterns/fields.py @@ -77,7 +77,39 @@ def do_find_field_lists( for _field in re.finditer(SPHINX_REGEX, text) ] _wrap_parameters = True - + elif style == "google": + _field_idx = [ + (_field.start(0), _field.end(0)) + for _field in re.finditer(GOOGLE_REGEX, text, re.MULTILINE) + ] + _wrap_parameters = False # Don't wrap Google-style field lists + elif style == "numpy": + _field_idx = [ + (_field.start(0), _field.end(0)) + for _field in re.finditer(NUMPY_REGEX, text, re.MULTILINE) + ] + _wrap_parameters = False # Don't wrap NumPy-style field lists + + # If no field lists were found for the current style, check for field lists + # from other styles and preserve them as-is (don't wrap). + if not _field_idx: + # Check for Google-style field lists (e.g., "Args:", "Returns:"). + # Use a more specific pattern that only matches known Google section names. + google_sections = r'^ *(Args|Arguments|Attributes|Example|Examples|Note|Notes|' \ + r'See Also|References|Returns|Return|Raises|Raise|Yields|Yield|' \ + r'Warns|Warning|Warnings|Receives|Receive|Other Parameters):$' + google_matches = list(re.finditer(google_sections, text, re.MULTILINE)) + if google_matches: + _field_idx = [(_field.start(0), _field.end(0)) for _field in google_matches] + _wrap_parameters = False + + # If still nothing, check for NumPy-style field lists + if not _field_idx: + numpy_matches = list(re.finditer(NUMPY_REGEX, text, re.MULTILINE)) + if numpy_matches: + _field_idx = [(_field.start(0), _field.end(0)) for _field in numpy_matches] + _wrap_parameters = False + return _field_idx, _wrap_parameters diff --git a/src/docformatter/patterns/lists.py b/src/docformatter/patterns/lists.py index 48acbdf..c91e8c9 100644 --- a/src/docformatter/patterns/lists.py +++ b/src/docformatter/patterns/lists.py @@ -83,24 +83,48 @@ def is_type_of_list( if is_field_list(text, style): return False - return any( - ( + # Check for various list patterns + for line in split_lines: + # Always check for non-field-list patterns + if ( is_bullet_list(line) or is_enumerated_list(line) or is_rest_section_header(line) or is_option_list(line) - or is_epytext_field_list(line) - or is_sphinx_field_list(line) - or is_numpy_field_list(line) - or is_numpy_section_header(line) - or is_google_field_list(line) - or is_user_defined_field_list(line) or is_literal_block(line) or is_inline_math(line) or is_alembic_header(line) - ) - for line in split_lines - ) + or is_user_defined_field_list(line) + ): + return True + + # For field list patterns from other styles: + # - When using epytext or sphinx (field-based styles), do NOT treat + # section-based styles (Google/NumPy) as lists to skip.
