Roadmap

The pynvl package is just warming up!
Here are the planned enhancements and future directions.

🔹 Core Functions

  • Initial helpers: nvl, decode, sign, noneif, nvl2
  • Add more PL/SQL-inspired helpers:
  • extract_xml

🔹 Pandas Integration

  • pd_nvl(series, default) => fill NaN/None with default
  • pd_decode(series, mapping, default) => map values with fallback
  • pd_sign(series) => vectorized numeric sign
  • pd_noneif(series)
  • pd_nvl2(series)

🔹 Regex Helpers

  • regexp_like(string, pattern) => boolean match
  • regexp_substr(string, pattern, occurrence=1) => extract substring
  • regexp_replace(string, pattern, replacement) => regex substitution
  • regexp_instr(string, pattern) => position of match

🔹 Testing & Quality

  • Expand test coverage across all functions
  • Cover edge cases (e.g. None == None in decode)

🔹 Documentation

  • Expand API docs with detailed examples

🔹 Longer-Term Ideas

  • Performance optimizations for large data sets

🔹 Contributions

New ideas are welcome! See CONTRIBUTING.md for guidelines.
