What is frontmatter?

A small R parser quietly becoming format-agnostic about front matter.

frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.

What is phyloatlas?

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

A small R parser quietly becoming format-agnostic about front matter.

◆ Current state

frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.

◆ Where it's heading

Each release widens the set of files it recognises without widening what it claims to do — standard YAML and TOML fences first, then comment-wrapped R and Python variants and PEP 723 inline script metadata, then shebang-prefixed scripts. The complementary thread is preserving what it found: format and fence type are attached as attributes so a document can be rewritten in the style it arrived in. The remaining rough edge is acknowledged in the notes, since comments and formatting inside the front matter do not survive a roundtrip.

◆ Prediction

Expect further delimiter styles as they appear in the wild, and likely work on making the roundtrip preserve comments and formatting, which the package currently flags as imperfect.

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

◆ Current state

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Where it's heading

The project's defining decision is that it archives the recipe rather than the corpus. Since 1.0.3 the Zenodo deposit holds metadata, provenance, and standardization code while the tree files live at their original sources, and the same principle was applied again when the TimeTree-of-Life was removed at the TimeTree project's request and reduced to a citation. What makes the correction log unusual is its direction: partitions keep getting reclassified from dated to undated as verification confirms the source papers described chronograms they never deposited. The atlas is being built to be honest about archival uncertainty rather than to maximize coverage.

◆ Prediction

The release cadence is driven by the manuscript review cycle, so expect corrections to continue until MEE acceptance and then slow sharply; the open thread most likely to produce the next one is the remaining recoverable archival uncertainty flagged across non-Condamine dated source trees.
