glyread vs glyrepr: at a glance
What is glyread?
glyread now hands every importer's output straight to Bioconductor.
glyread is the import layer, converting output from pGlyco3, Byonic, GlycanFinder, GlyHunter, and pGlycoQuant into glycoverse objects. Version 0.12.0 changed what those objects are: every read_*() function now returns GlycomicSE or GlycoproteomicSE, and 0.12.1 raised the glyexp floor to 0.16.0 to match. Earlier releases in the window went to format handling, particularly multi-glycosite glycopeptides and linkage-specific derivatization presets.
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.

glyread
0.0ANALYTICS
glyread now hands every importer's output straight to Bioconductor.
◆ Current state
glyread is the import layer, converting output from pGlyco3, Byonic, GlycanFinder, GlyHunter, and pGlycoQuant into glycoverse objects. Version 0.12.0 changed what those objects are: every read_*() function now returns GlycomicSE or GlycoproteomicSE, and 0.12.1 raised the glyexp floor to 0.16.0 to match. Earlier releases in the window went to format handling, particularly multi-glycosite glycopeptides and linkage-specific derivatization presets.
◆ Where it's heading
As the stack's entry point, glyread absorbs container decisions first and hardest: because it constructs the objects everything downstream consumes, it had no compatibility path and simply switched return types. The other visible thread is coverage of upstream software, adding importers and presets as new search engines and protocols appear. Those two threads rarely interact.
◆ Prediction
Expect the next releases to return to importer coverage, adding formats or presets, now that the container question is settled at the source.
glyrepr
2.5ANALYTICS
The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.
◆ 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.
