pycel2sql

Cuts a new pycel2sql release by validating the working tree, picking the semver bump, tagging vX.Y.Z, and pushing the tag to trigger .github/workflows/release.yml which runs CI, builds an sdist + wheel via hatch-vcs, and publishes to PyPI via OIDC trusted publishing. Use when shipping a new patch, minor, or major version of pycel2sql to PyPI.

Ports features and bug fixes from upstream cel2sql Go (the canonical source) and cross-references cel2sql4j Java into pycel2sql. Use when syncing upstream changes — the workflow enumerates candidate commits since the last sync, verifies whether each change is already applied (many turn out to be done already), maps Go and Java idioms to Python equivalents, ports the test, and updates relevant docs.

Adds a new CEL function, operator, macro, or comprehension form to pycel2sql by extending Converter visit methods in src/pycel2sql/_converter.py, deciding whether a new Dialect ABC abstract method is needed, implementing it across all six dialects when SQL diverges, and adding parametrized test cases. Use when wiring a new CEL string method (toLowerCase, isAlpha), timestamp method (toISOString), free-function helper, operator overload, or comprehension form across PostgreSQL, MySQL, SQLite, DuckDB, BigQuery, and Apache Spark.

Adds a new SQL dialect to pycel2sql by creating src/pycel2sql/dialect/<name>.py (subclass of the Dialect ABC), registering in the DialectName enum and the get_dialect() factory, threading new test cases through every parametrized test class, and updating the README badge grid and dialect-comparison tables. Use when porting a new database backend (Trino, Snowflake, ClickHouse, MS SQL, Athena, Oracle) or any new analytics engine.
