orthonym.validation.spelling.models

Note

Internal API. Names and behaviour may change between releases.

Shared readings of a name for the spelling checks: the abstention marks, the parsed units of a name, and the numbering models of parents whose numbering symmetries are known from the name alone (an unbranched carbon chain, a carbocyclic, retained or Hantzsch-Widman monocycle, naphthalene, anthracene). No naming code, no OPSIN.

orthonym.validation.spelling.models.P10 = re.compile('(pyranos|furanos|osyl|uronic|ose\\b|osid|glycer|L-|D-|DL-|\\bα-|\\bβ-|adenosin|guanosin|uridin|cytidin|thymidin|inosin|cholest|androst|pregn|estr|gonan|morphinan|ergolin|abieta|labda|kaura|carotene|r)

lexical marks of the classes (carbohydrates, nucleosides, stereoparents, amino acids and peptides, carotenoids, coordination names): the substitutive checks abstain on them

orthonym.validation.spelling.models.show(text)

A unit’s text for a failure detail: child enclosures shown as ‘(…)’.

orthonym.validation.spelling.models.read_units(name)

parse_name(name), or None when the marks do not pair (the check reports that).

orthonym.validation.spelling.models.int_locs(locs)

orthonym.validation.spelling.models.ring_or_chain_model(p, is_subst_unit)

(kind, n, perms, feats) of a unit whose parent’s numbering symmetries are known from the name alone (an unbranched carbon chain, a carbocyclic or retained / Hantzsch-Widman monocycle, naphthalene, anthracene), or None. feats['prefix'] holds (key, locants) of the prefixes on numbered positions, feats['prefix_src'] the prefixes themselves in the same order (a prefix whose locants are all element locants goes to feats['letter']).

orthonym.validation.spelling.models.bond_loc(a, b, n, kind)

orthonym.validation.spelling.models.vector(feats, mp, n, kind, letters_first=True)

The locant sets of a unit under numbering mp, in the order of the criteria. letters_first: an element locant (‘N4’) ranks below a numeral,:3195); False ranks it above (the order the PIN ‘N4,2-dimethylpentane-2,4-diamine’:26371 needs).
