Overview of recent projects and how they relate:

• clj-kondo: Clojure linter, compiled with GraalVM for fast startup. While implementing clj-kondo I realized that analyzed code could not only be linted, but also interpreted. This gave rise to sci.

• jet: converts between JSON, EDN and Transit. Supports minimal query language in the spirit of jq. While implementing the query language for jet, I realized that using normal Clojure instead of a DSL was better for most Clojure users. This gave rise to sci.

• edamame: EDN parser with location metadata and configurable dispatch table. This way of parsing is inspired by rewrite-clj, but it skips the intermediate node representation. This parser was extracted from sci.
