pegboard vs tulpa
A side-by-side editorial comparison of pegboard and tulpa — release velocity, themes, recent moves, and the top alternatives to consider.
pegboard vs tulpa: at a glance
What is pegboard?
The Carpentries' lesson parser spends its releases keeping pace with tinkr underneath it.
pegboard reads and validates Carpentries lesson source, and its recent releases are dominated by tracking changes in tinkr, the Markdown layer it sits on. The 0.7.8 switch from yaml to frontmatter handling needed a hotfix three days later in 0.7.9; 0.7.6 was similarly a compatibility fix for a tinkr show argument change. The genuinely additive work — tabset panel support in 0.7.5, caution divs in 0.7.7 — is smaller and less frequent.
What is tulpa?
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

pegboard
0.0ANALYTICS
The Carpentries' lesson parser spends its releases keeping pace with tinkr underneath it.
◆ Current state
pegboard reads and validates Carpentries lesson source, and its recent releases are dominated by tracking changes in tinkr, the Markdown layer it sits on. The 0.7.8 switch from yaml to frontmatter handling needed a hotfix three days later in 0.7.9; 0.7.6 was similarly a compatibility fix for a tinkr show argument change. The genuinely additive work — tabset panel support in 0.7.5, caution divs in 0.7.7 — is smaller and less frequent.
◆ Where it's heading
This is infrastructure whose roadmap is largely set by its dependency. Contributor churn is visible in the release notes, with several first-time contributors and the release role passing between maintainers, which suggests a community project maintained in bursts rather than to a plan. New lesson-authoring features arrive when someone contributes one, not on a cadence.
◆ Prediction
The next release will most likely be another tinkr compatibility pass or a small addition to the set of recognised div types, following the pattern of every release in this window.
tulpa
7.5ANALYTICS
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
◆ Current state
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.
◆ Where it's heading
Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.
◆ Prediction
Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
