r2rtf
The clinical-report table engine learned Chinese, then learned to leave RTF entirely
A side-by-side editorial comparison of nodbi and typst-gather — release velocity, themes, recent moves, and the top alternatives to consider.
One document API over six databases, and every release is spent absorbing their JSON engines' churn
nodbi presents a single document-store interface — docdb_create, docdb_query, docdb_update — over SQLite, DuckDB, PostgreSQL, MongoDB, CouchDB and Elasticsearch. The engineering reality behind that abstraction is that each backend's JSON support keeps moving, and the releases show it: jsonb_tree adopted as RSQLite 2.4.4 exposes it, json_tree reworked for DuckDB 1.3.0, then avoided entirely for DuckDB listfields because it was too slow. The 0.11.0 release in late 2024 is the one that changed the contract, making docdb_query() return columns of a single consistent type.
Extracted from Quarto's CLI, typst-gather learned to explain a dependency tree before fetching it.
typst-gather collects Typst packages into a local cache so documents build offline and hermetically. It was extracted from quarto-cli and reached CRAN-equivalent shape in three releases over a single day, then added an `analyze` subcommand that walks `@Preview` and `@Local` imports — following transitive dependencies of local packages — and prints structured JSON without downloading or copying anything.

Two threads dominate. The first is performance, pursued backend by backend: fast direct NDJSON import moved from DuckDB-only to SQLite and PostgreSQL, query refactors chasing each DuckDB release, and the removal of expensive tree-walking where a cheaper path exists. The second is making results predictable — consistent column types, version checks on the database backend, clearer messages when a Postgres database does not exist yet or when column names contain the dots nodbi reserves for JSON paths.
Given that most recent releases are triggered by DuckDB and RSQLite version changes, the next one likely follows the same pattern — adopting a new JSON function or working around a slow one. The duplicate-_id handling added in 0.14.0 suggests NDJSON ingestion edge cases are the current active area.

The 0.2.0 restructuring is the tell: subcommands with backwards compatibility, config readable from stdin, and every diagnostic message moved to stderr so stdout carries nothing but JSON. Those are the conventions of a tool meant to be called by another program, not typed by a person. Given its origin inside Quarto's toolchain, the plausible consumer is a build system that needs to know a document's package requirements before deciding what to fetch.
The analyze path currently reports imports; the natural extension visible from here is acting on that report — lockfile output or verification that a cache satisfies a document's dependency set — though the entries do not commit to either.
