Initial release.
Get Started and glyco-regex syntax vignettes introduce structural queries through biological examples.
New rex_compile() validates and compiles reusable glycan patterns with residue classes, linkage constraints, branches, repetition, anchors, lookaround, and named captures.
New rex_count() and rex_detect() count and detect structural matches. Query functions accept glycan strings in any format supported by glyparse::auto_parse(), including mixed-format vectors, as well as glyrepr_structure vectors and glyrepr-compatible igraph objects.
New rex_extract() and rex_extract_all() return matching glycan fragments while preserving reducing-end anomeric information.
New rex_locate() and rex_locate_all() identify the nodes and edges of structural matches.
New rex_match() and rex_match_all() return structural matches and named captures.
New rex_subset() and rex_which() select matching glycans or their indices.
