glymotif vs vellumverse: at a glance
What is glymotif?
A glycan motif matcher trading convenience wrappers for speed, strictness and explicit specs.
glymotif detects and counts structural motifs in glycans, over a built-in motif database or user-supplied structures, with fuzzy modification matching and alignment control. Database motifs are now requested through a db_motifs_spec object carrying their own matching parameters rather than as a name vector with loose arguments, and db_motif_info() exposes the built-in set as an inspectable tibble. A lenient mode lets lower-information glycans match more specific motifs while concrete mismatches still fail, and low-level entry points work directly on igraph objects for other package authors.
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.

2.5ANALYTICS
A glycan motif matcher trading convenience wrappers for speed, strictness and explicit specs.
◆ Current state
glymotif detects and counts structural motifs in glycans, over a built-in motif database or user-supplied structures, with fuzzy modification matching and alignment control. Database motifs are now requested through a db_motifs_spec object carrying their own matching parameters rather than as a name vector with loose arguments, and db_motif_info() exposes the built-in set as an inspectable tibble. A lenient mode lets lower-information glycans match more specific motifs while concrete mismatches still fail, and low-level entry points work directly on igraph objects for other package authors.
◆ Where it's heading
Performance has been a recurring line item across at least four releases, culminating in optimised graph searches and candidate filtering aimed at batch analyses, which points at the real workload being whole experiments rather than single glycans. The API has moved the other way from convenience toward explicitness: the add_motifs_lgl() and add_motifs_int() wrappers are deprecated in favour of composing with dplyr or glyexp verbs, optional arguments must now be named, and loose matching parameters were folded into the spec object. Documentation is being steered toward the cohort's newer container types, so this package is following a coordinated migration rather than setting its own course.
◆ Prediction
With the deprecated annotation wrappers on their way out and documentation already pointing at the replacement verbs, their removal is the likely next breaking change. The lenient matching mode is new enough that its boundary against concrete mismatches will probably need tuning as users apply it to real, partially resolved data.
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.
