Radixor-C for Python

radixor-c is Radixor's focused CPython runtime. Its native engine is implemented directly against the CPython C API, which minimizes the overhead of stemming one word at a time. It needs no JVM or Rust runtime.

from radixor_c import Stemmer

stemmer = Stemmer("en")
stemmer.stem("running")  # 'run'

Radixor-C uses the same standard models, stemming semantics and public stemming surface as the radixor Python package. Its scope is intentionally narrower: it loads prepared compiled Radixor models but does not currently compile text dictionaries or modify tries.

When to choose it

Choose radixor-c when:

  • Python code calls the stemmer for individual words and native-call overhead matters;
  • the application uses standard models or already prepared .rxc files;
  • basic dominant and multi-result stemming APIs are sufficient.

Choose radixor when:

  • large batches are the primary workload—its strongest throughput comes from amortizing the Python/native boundary with batch calls;
  • Python must compile a text dictionary into a compiled Radixor model;
  • the application needs the broader PyO3 API described in Python usage and API.

Choose Java for the complete reference API, including reopening and extending compiled tries, selectable reduction modes and the complete model toolchain. This is a capability distinction, not a model-quality distinction.
