glyrepr vs vellumverse: at a glance
What is glyrepr?
The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.
glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.
What is vellumverse?
A meta-package whose entire changelog is a version pin, tracking an ecosystem moving faster than it is.
vellumverse attaches the vellum graphics ecosystem in one library() call, reports which versions loaded, lists the bundled packages and surfaces functions masked across them. It is deliberately dependency-light, having dropped rlang and declared only what the conflict reporter actually uses. Since 0.2.0 every release has been a version pin bump rather than new behaviour of its own.

◆ Current state
glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.
◆ Where it's heading
This package sets the pace for the cohort, and its breaking changes show up as compatibility patches in glyanno, glyenzy and glymotif within days. The direction is toward behaving like a well-built vctrs type: 0.10.0 rewrote the internals to support names and NA properly, 0.11.0 made structure level a vector-wide scalar rather than a per-element value, and the recent releases keep making failure explicit rather than silent, with strict input checks and typed errors replacing quiet drops. Dependencies get shed as readily as features get added, with the parallel-mapping arguments and their furrr and future dependencies removed outright in 0.13.0.
◆ Prediction
The graph-table conversions added in 0.13.0 and the name-preserving low-level constructors in 0.14.0 both look like foundations for other packages to build structures programmatically, so expect that surface to firm up next. Given the cadence of breaking changes, a 1.0 that freezes the type semantics is the more consequential thing to watch for.
vellumverse
5.0ANALYTICS
A meta-package whose entire changelog is a version pin, tracking an ecosystem moving faster than it is.
◆ Current state
vellumverse attaches the vellum graphics ecosystem in one library() call, reports which versions loaded, lists the bundled packages and surfaces functions masked across them. It is deliberately dependency-light, having dropped rlang and declared only what the conflict reporter actually uses. Since 0.2.0 every release has been a version pin bump rather than new behaviour of its own.
◆ Where it's heading
The release record is an index of other packages' work: four of the last six entries do nothing but raise the floor on vellum, vellumplot and vellumwidget. The cadence tells the real story, with pins moving roughly weekly and each bump chasing a minor release somewhere downstream, so the meta-package is currently a distribution convenience rather than a component. The one genuinely structural release in the window was 0.2.1, which trimmed the dependency surface to keep an attach-only package cheap to install.
◆ Prediction
Expect the pin bumps to keep pace with the ecosystem's weekly releases rather than any feature of its own, and the pin on vellumplot to move again as the interaction grammar the widget now depends on continues to land. Whether vellumverse ever grows beyond attach-and-report is not visible in these entries.
