pcblib_find_footprint

Build an index of footprint names across a folder of PcbLib files and run simple fuzzy searches against that index.

This is useful when a project has many local footprint libraries and you need to find which library contains a footprint before inserting it into a board or splitting/combining libraries.

What It Shows

  1. AltiumPcbLib.from_file(...)
  2. Iterating pcblib.footprints
  3. Building a {library_filename: [footprint_name, ...]} dictionary
  4. Searching footprint names with a lightweight Python fuzzy matcher

Run

From the repo root:

uv run python examples\pcblib_find_footprint\pcblib_find_footprint.py

To scan a different folder:

uv run python examples\pcblib_find_footprint\pcblib_find_footprint.py --pcblib-dir path\to\pcblibs --query R0603 --query TC2030

The example uses queries such as r0603, tc2030, msop, and tp smt to show exact, partial, and approximate matches.

Output

The script prints the discovered footprints and writes:

examples/pcblib_find_footprint/output/footprint_index.json
