Beyond jj: config & tools ecosystem

Read on arko.netLobsters 89

Summary

A talk‑style overview of the growing jj ecosystem, covering new built‑ins (bookmark‑advance, bisect‑run, run, fix, tag, arrange, converge), clever alias tricks (subcommand aliases, git‑push‑like publish alias), the community‑maintained alias directory, and current forge integrations (GitHub stacked PRs, JJHub, Radicle, Tangled).

  • jj now ships core commands that previously required external scripts: `jj bookmark advance`, `jj bisect run`, `jj run`, `jj fix`, `jj tag`, `jj arrange`, and `jj converge`.
  • Alias subcommands can be emulated with a chain of aliases using `util exec` and Bash, enabling hierarchical commands like `jj foo bar`.
  • A community‑curated alias directory (https://www.lysator.liu.se/~axl/jj‑aliases/) lets users share and vote on useful jj aliases.
  • Forge support is emerging: GitHub stacked PRs, JJHub overlay, Radicle patch flow, and the ATProto‑based Tangled forge.

jj is positioning itself as a first‑class alternative to Git by closing feature gaps (bisect, tagging, interactive rebase) and offering a flexible alias system. Understanding these built‑ins and integration patterns lets teams adopt jj without a large external tooling overhead and prepares them for…

  2. Article: Your Next DSL Author Is a Language Model

    Typed Domain Grounding (TDG) embeds a DSL inside a mainstream language the LLM already knows (e.g., Kotlin) and uses the host compiler as an oracle. The author describes five building blocks—embedding, choosing a host language with high training‑data frequency, compiler‑driven type safety, a generate‑compile‑repair loop, and an on‑demand teaching tool—and shows measured results from kUML, a Kotli…

  3. Article: Beyond Relevance: A Governance-First Architecture for Enterprise Personalization

    The article proposes a governance‑first architecture for enterprise personalization, where policy‑driven steps (memory, journey graph, AI routing, scoring, trust checks, outcome simulation) shape the recommendation before it is returned. A reference FastAPI implementation demonstrates the pattern with external YAML policies and optional LLM assistance.
