Change History

comment:1 Changed 4 years ago by Paul Kienzle

  • Status changed from new to assigned

comment:2 Changed 4 years ago by Paul Kienzle

(In [976]) Python bindings to libNeXus. Refs #101

comment:3 Changed 4 years ago by Paul Kienzle

The new bindings have a memory leak (90k per file open/close cycle; no tests of memory usage for other operations). This ticket will remain open until that is resolved.

A layer above napi which understands the DTDs and can translate, e.g., dates to python dates and values to values in particular units may be provided later.
