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 L1centrality?

A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.

L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.

0.0

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.

0.0

A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.

◆ Current state

L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.

◆ Where it's heading

The package has moved from defining measures to operationalizing them. 0.5.0 was the inflection: parallel local computation and list-valued group input both target users running these measures over many vertex sets or large graphs rather than illustrating them on one. The same release renamed weight_transform and eta to edge_weight_transform and vertex_weight, and added an explicit message when a distance matrix is received — the signature of a maintainer fielding the same misuse repeatedly.

◆ Prediction

The last two releases carry no functional change, so the near-term path is maintenance rather than new measures; a 0.6.0 would most likely extend parallelism beyond L1centLOC to the other computationally heavy variants.
