CIFT

Caltech Intermediate Form parser in pure Python

• github: https://github.com/maybeetree/cift
• pypi: https://pypi.org/project/cift/0.0.1/

Under construction

Currently, CIFT is a utility for use in unit tests of RAIMAD, a different project I am working on. As such, it is only guaranteed to support CIF files that RAIMAD produces, and not all CIF files in general.

Turning CIFT into a general-purpose CIF parser is a long-term future goal.

Roadmap

• Basic parsing
  • P (polygons)
  • B (box)
    • rotation
  • Comments
  • Subroutines (DS and DF)
  • Translation and rotation (subroutines)
• Inspection
  • Get CIF file as a list of geometries on each layer
  • Get CIF file as a tree representing subroutine calls

Overall Goals

• Pure Python, no dependencies
• easy to understand code
• mypy --strict has no complaints
• in abscence of a CIF spec, emulate KLayout's CIF parser as closely as possible.

Name

• "CIFT", pronounced like "sift". Think of putting a CIF file into a sieve and letting the syntax crystallize into grains of sand that fall away to reveal the geometries it represents.
