Switch build-backend from setuptools.backends.legacy to setuptools.build_meta (legacy backend requires newer pip not available in all CI environments) - Move rpy2 to optional [r] extra; add pandas as core dependency - Add pytest.importorskip("rpy2") guards for seqstats, RIPDiff, JensenShannon, mySam, Chip, continuousData tests (these modules import rpy2 at module level) - Fix remaining Python 2 syntax in sequencelib.py: - raise "string", arg → raise ValueError(...) - print "%d" % x → print("%d" % x) - import prob → from . import prob (bare sibling import) - Fix remaining Python 2 syntax in solid.py: - import misc → from . import misc - print >>outhand, ... → outhand.write(...) - print "...", / print "" → print(...) - dict.has_key() → in operator - Fix invalid regex escape sequence in util.py (\$ → r-string) - Update requirements.txt to comment out rpy2 (now optional) - Add ruff to dev dependencies in pyproject.toml All 21 tests now pass (6 skipped without rpy2/R installed). https://claude.ai/code/session_01CVzyi7WGAKyTJzbmnSNF6r --- .github/workflows/ci.yml | 2 + pyproject.toml | 8 +- requirements.txt | 7 +- src/biolib.egg-info/PKG-INFO | 188 +++++++++++++++++++++++ src/biolib.egg-info/SOURCES.txt | 53 +++++++ src/biolib.egg-info/dependency_links.txt | 1 + src/biolib.egg-info/requires.txt | 11 ++ src/biolib.egg-info/top_level.txt | 2 + src/seqlib/sequencelib.py | 9 +- src/seqlib/solid.py | 25 +-- src/seqlib/util.py | 2 +- tests/test_seqlib.py | 6 + 12 files changed, 288 insertions(+), 26 deletions(-) create mode 100644 src/biolib.egg-info/PKG-INFO create mode 100644 src/biolib.egg-info/SOURCES.txt create mode 100644 src/biolib.egg-info/dependency_links.txt create mode 100644 src/biolib.egg-info/requires.txt create mode 100644 src/biolib.egg-info/top_level.txt diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 673de07..0753c8a 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -37,6 +37,8 @@ jobs: sudo apt-get install -y libbz2-dev liblzma-dev libcurl4-openssl-dev -

Python 2 syntax and clean up ruff errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Run 2to3 print fixer on smRNA, lincClonelib, lincName, lincRNAs, dbConn, go, gibson, genomelib, primer3lib (print >>stream, expr → print(..., file=...)) - Fix remaining Python 2 except A, B: syntax → except A as B: in gibson.py, lincClonelib.py, lincName.py - Fix backtick repr expressions (`expr` → repr(expr)) in myDataTypes.py - Fix <> operator remaining in shrimp.py - Fix raise 'string', arg → raise error('arg') in myDataTypes.py - Fix bare import sequencelib → from . import sequencelib in smRNA.py - Fix E731: convert lambda assignment to def in algorithms.py - Fix E702: split semicolon-separated statements in util.py - Fix F507: wrong number of % format args in primer3lib.py - Fix F823: rename loop variable 'next' → 'nxt' in mySam.py (was shadowing builtin) - Fix E402 in smRNA.py: merge dangling docstring into module docstring - Add noqa: E402 to misc.py late import (intentional for code organization) - Expand ruff ignore list: add E101, E402, E731 suppressed for legacy code - Remove .bak files left by lib2to3 (via .gitignore) ruff
