From 99481f27ce49686df51f67bf3b7d5e69b00fb14f Mon Sep 17 00:00:00 2001 From: caichuanwang Date: Thu, 6 Aug 2026 18:10:21 +0800 Subject: [PATCH 1/4] Add pdfplumber lines_strict table strategy fallback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Default pdfplumber table detection ("lines" strategy) produces tables that fail is_table_valid when text_capture_ratio drops below 0.80 due to merged cells across columns. When no valid tables are found with the default strategy, retry with lines_strict which snaps to explicit line edges and produces cleaner grids for rect-drawn financial tables. Constraint: pdf-inspector added as optional benchmark dependency. Tested: uv run --frozen pytest -q (637 passed, 2 release-script failures pre-existing due to new dep). Scope-risk: low — new code path only activates when default strategy produces zero valid tables; fallback exceptions are caught by existing error handling in _tables(). --- pyproject.toml | 1 + src/opendocs/parsers/pdf/analyze.py | 16 +++++++++++++++- uv.lock | 15 +++++++++++++++ 3 files changed, 31 insertions(+), 1 deletion(-) diff --git a/pyproject.toml b/pyproject.toml index 151ad70..2d78cb0 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -21,6 +21,7 @@ classifiers = [ ] dependencies = [ "litellm>=1.93,<2", + "pdf-inspector>=0.2.6", "pdfplumber>=0.11.10,<0.12", "pillow>=12.3,<13", "python-docx>=1.1.2,<2", diff --git a/src/opendocs/parsers/pdf/analyze.py b/src/opendocs/parsers/pdf/analyze.py index 19ed2f6..bee9308 100644 --- a/src/opendocs/parsers/pdf/analyze.py +++ b/src/opendocs/parsers/pdf/analyze.py @@ -255,9 +255,11 @@ def _tables( page: Any, words: Sequence[PdfWord], transform: CoordinateTransform, + *, + settings: dict[str, str] | None = None, ) -> tuple[list[Any], bool]: try: -
