glyparse 0.7.1

CRAN release: 2026-07-08

Minor improvements and bug fixes

• Parser output now uses glyrepr’s public structure constructor, preventing tidyverse joins on parsed structures from failing with glyrepr 0.13.0. (#33)

glyparse 0.7.0

CRAN release: 2026-07-06

New features

• auto_parse() now detects GlyCAM IUPAC, IUPAC-compact, KCF, and LINUCS structures and routes them to the corresponding parser (#26, #28, #30, #31).
• Parser functions gain a progress argument for opt-in progress bars when parsing large inputs (#29).
• New parse_glycam_iupac() parses GlyCAM IUPAC structures (#25, #27).
• New parse_iupac_compact() parses IUPAC-compact structures (#28).
• New parse_kcf() parses KCF structures (#30).
• New parse_linucs() parses LINUCS structures (#31).

Minor improvements and bug fixes

• parse_glycoct() now accepts space-separated GlycoCT records, such as records stored in CSV exports (#24).
• parse_glycoct() now parses GlycoCT alditol residues as regular reducing-end glycans with unknown anomer configurations (#22).
• parse_glycoct() now supports generic GlycoCT HEX, N-acetylated HEX, deoxy-HEX, and sialic acid descriptors, including direct n-sulfate substituents on amino sugars (#24).
• parse_wurcs() now parses WURCS alditol residues as regular reducing-end glycans with unknown anomer configurations (#21).
• parse_wurcs() now supports additional generic residue descriptors, ambiguous sialic acid descriptors, and uppercase residue IDs for large structures (#23).

glyparse 0.6.1

CRAN release: 2026-06-20

Minor improvements and bug fixes

• parse_wurcs() now supports ambiguous u residues and unknown ring closure residues (? ring position).
• parse_wurcs() now correctly handles WURCS N-sulfate substituent codes (*NSO/3=O/3=O).
• parse_glycoct() now preserves unknown reducing-end ring positions and matches amino sugars with unknown ring bounds.

glyparse 0.6.0

CRAN release: 2026-04-29

New features

• Add a on_failure parameter to all parser functions. When on_failure = "error", the parser will throw an error when it encounters an unparsable string. When on_failure = "na", the parser will return NA for unparsable strings. The default is “error”, for backwards compatibility.

glyparse 0.5.7

CRAN release: 2026-03-14

Minor improvements and bug fixes

• parse_iupac_extended() now accepts input with plain text equivalents (“alpha”, “beta”, “->”). (#10)

glyparse 0.5.6

CRAN release: 2026-02-24

Minor improvements and bug fixes

• Parser functions are now significantly faster (10-30x) for large inputs.
• Replaced deprecated dplyr::case_match() with dplyr::recode_values() in parsers to prevent warnings.

glyparse 0.5.5

CRAN release: 2026-02-04

Minor improvements and bug fixes

• All parser functions now preserve names of input character vectors.
• All parser functions now supports NA values in the input character vectors.

glyparse 0.5.4

CRAN release: 2026-01-27

Minor improvements and fixes

• Adapt to glyrepr 0.10.0.

glyparse 0.5.3

CRAN release: 2025-11-04

Minor improvements and fixes

• Prepare for release on CRAN.

glyparse 0.5.2

Minor improvements and fixes

• glyaprse now depends on the CRAN version of glyrepr.

glyparse 0.5.1

Minor improvements and fixes

• parse_iupac_extended() and parse_iupac_short() now support generic monosaccharides, e.g. “Hex”, “HexNAc”, “HexN”.

glyparse 0.5.0

New features

• Add parse_linear_code() to parse Linear Code strings.
• auto_parse() now supports Linear Code strings.

Minor improvements and fixes

• Revise the documentations of all parsers to be more accurate about return value type.

glyparse 0.4.5

Minor improvements and fixes

• Fix the bug that linkages like “1→3/4” cannot be parsed by parse_iupac_extended().
• Fix the bug that linkages like “b1-a3|a4” cannot be parsed by parse_wurcs().
• Fix the bug that linkages like “a3/4” cannot be parsed by parse_iupac_short().
• Fix the bug that linkages like “3:3o(3|6+1)4d” cannot be parsed by parse_glycoct().

glyparse 0.4.4

Minor improvements and bug fixes

• Update dependencies to depend on release versions of glycoverse packages.

glyparse 0.4.3

Minor improvements and fixes

• Fix bugs introduced by the breaking changes in glyrepr v0.7.0.

glyparse 0.4.2

Minor improvements and fixes

• Fix some incorrect structure strings in vignettes.

glyparse 0.4.1

Minor improvements and fixes

• Fix some incorrect structure strings in tests and documentations.
• Remove some legacy documentations.

glyparse 0.4.0

Breaking changes

• parse_iupac_condensed() and parse_iupac_short() now require the reducing-end monosaccharide to have anomer information. For example, “Neu5Ac(a2-” and “Neu5Aca-” are valid, but “Neu5Ac” is not.

glyparse 0.3.1

Minor improvements and fixes

• parse_pglyco_struc() now support “aH” and “pH” monosaccharides.

glyparse 0.3.0

New features

• Add auto_parse() to automatically detect and parse different glycan structure string formats.

Minor improvements and fixes

• Better error messages. Before:

  > parse_iupac_condensed("bad_glycan")

  Error in `purrr::map()` at glyparse/R/struc-parser-wrapper.R:13:3:
  ℹ In index: 1.
  Caused by error in `value[[3L]]()`:
  ! Could not parse IUPAC-condensed string: {.val {x}}
  ℹ Invalid characters or format in IUPAC-condensed string
  Run `rlang::last_trace()` to see where the error occurred.

  Now:

  > parse_iupac_condensed("bad_glycan")

  Error in `parse_iupac_condensed()`:
  ! Can't parse: "bad_glycan"
  Run `rlang::last_trace()` to see where the error occurred.

glyparse 0.2.1

Minor improvements and fixes

• Update README.
• A “Get Started” vignette is added.

glyparse 0.2.0

Major improvements

• Add parse_glycoct() to parse glycans in GlycoCT format.

glyparse 0.1.2

Minor improvements

• parse_iupac_short(), parse_iupac_extended(), parse_iupac_condensed(), parse_wurcs() now support multiple substituents on the same monosaccharide, to align with the updates in glyrepr v0.5.0.
