Glean – System for collecting, deriving and querying facts about source code
We use this to power things like find-references or jump-to-def, "symbol search" and autocomplete, or more complicated code queries and analysis (even across languages). Imagine rich LSPs without a local checkout, web-based code queries, or seeding fuzzers and static analyzers with entry points in code.Our focus has been on very large scale, multi-language code indexing, and then low latency (e.g. hundreds of micros) query times, to drive highly interactive developer workflows.
