Crate tsv_html 

HTML spec data and the answers the HTML spec gives — part of tsv, published for tsv’s Svelte support (tsv_svelte). The long-term target is a spec-faithful HTML library; today the crate holds what tsv’s Svelte parser reads from the spec: the named character references table, matched as the tokenizer matches it (match_named_character_reference, answering a NamedCharacterReference).

The lookup is a pure function over text, independent of any one parser or tool. Names are matched exactly, as authored: the lookup is case-sensitive, as the spec’s table is (Á and á are different references).

use tsv_html::match_named_character_reference;

// `&lt;` names `<`, its `;` included
let lt = match_named_character_reference("lt;").unwrap();
assert_eq!((lt.name(), lt.characters()), ("lt;", "<"));
// the longest name that starts the text wins: `&notin;` over `&not`
let notin = match_named_character_reference("notin;").unwrap();
assert_eq!((notin.name(), notin.characters()), ("notin;", "∉"));

Stability

The public signatures follow 0.x semver like every tsv crate: a breaking change ships only in a minor release. What the lookup answers may change in any release, tracking the spec and what tsv needs.

License

The named-reference table is generated from WHATWG’s entities.json and compiled in under BSD-3-Clause, beside tsv’s own 0BSD (the crate’s license is 0BSD AND BSD-3-Clause); the crate’s NOTICE file carries the attribution and both licenses.

Structs

NamedCharacterReference

A named character reference match_named_character_reference found: a row of the spec’s named character references table, its name and the characters it stands for.

Functions

match_named_character_reference

The longest named character reference at the start of input, or None when no name in the table starts it.
