What is downlit?

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

What is Trunk?

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

downlit vs Trunk: editorial side-by-side

D
downlit
INFRA · APIS
0.0

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

◆ Current state

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

◆ Where it's heading

The package reached its intended shape in the 0.4.x pair and has been static since. Its work now is reacting to the language and toolchain: a new pipe operator to highlight, an R-devel change to survive, a UTF-8 parsing crash routed around by simplifying the algorithm. Autolinking coverage, which drew steady contributions through 0.4.1, has not been extended since 2022.

◆ Prediction

Expect the next release to track another R or pandoc change rather than extend highlighting or linking.

T
Trunk
INFRA · APIS
0.0

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

◆ Current state

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

◆ Where it's heading

Trunk is making Merge Queue programmable and observable: APIs, IaC, metrics endpoints, and richer dashboards point at customers who manage CI at scale and want it wired into their existing tooling. Flaky Tests is gaining automation hooks (Jira issue creation, configurable threshold monitors) that move it from detection toward workflow.

◆ Prediction

Expect continued API, metrics, and integration depth on Merge Queue, and more automated remediation paths for Flaky Tests, as Trunk leans into programmability for larger engineering orgs.
