Changes in version 0.6.0 (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.

                 Changes in version 0.5.7 (2026-03-14)                  

Minor improvements and bug fixes

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

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.

                 Changes in version 0.5.5 (2026-02-04)                  

Minor improvements and bug fixes

Minor improvements and fixes

    return value type.

                        Changes in version 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

                        Changes in version 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.

                        Changes in version 0.3.1                        

Minor improvements and fixes

                        Changes in version 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.

                        Changes in version 0.2.1

Major improvements

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

                        Changes in version 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.
