To index Python we use SourceGraph's SCIP indexer for python. SCIP is a new format for tools to share information about code. Releases of scip-python can be installed with yarn or npm and used as indexers for SCIP, which Glean will accept. The indexer itself requires a python runtime.

Run the indexer​

The indexer is run via the main glean CLI tool.

> cabal build exe:glean

And index your Python repository with:

glean index python-scip DIR --db NAME/INSTANCE


  • DIR is the root directory containing the Python project
  • name/hash is the name of the repository to create

Provide the usual --db-root and --schema or --service arguments to glean

In the shell​

Python source can also be indexed directly from the Glean shell:

:index python-scip DIR

The shell will pick a DB name and hash for you based on DIR.


The schema is in glean/schema/source/scip.angle
