2023-09-03fix: most error spans mistakenly being emptyMartin Fischer
With codespan_reporting an empty span shows up exactly like a one-byte span, which is why I didn't notice this mistake earlier.

2023-09-03fix!: remove adjusted_current_node_present_and_not_in_html_namespaceMartin Fischer
Conceptually the tokenizer emits tokens, which are then handled in the tree construction stage (which this crate doesn't yet implement). While the tokenizer can operate almost entirely based on its state (which may be changed via Tokenizer::set_state) and its internal state, there is the exception of the 'Markup declaration open state'[1], the third condition of which depends on the "adjusted current node", which in turn depends on the "stack of open elements" only known to the tree constructor. In 82898967320f90116bbc686ab7ffc2f61ff456c4 I tried to address this by adding the adjusted_current_node_present_and_not_in_html_namespace method to the Emitter trait. What I missed was that adding this method to the Emitter trait effectively crippled the composability of the API. You should be able to do the following: struct TreeConstructor<R, O> { tokenizer: Tokenizer<R, O, SomeEmitter<O>>, stack_of_open_elements: Vec<NodeId>, // ... } However this doesn't work if the implementation of SomeEmitter depends on the stack_of_open_elements field. This commits remedies this oversight by removing this method and instead making the Tokenizer yield values of a new Event enum: enum Event<T> { Token(T), CdataOpen } Event::CdataOpen signals that the new Tokenizer::handle_cdata_open method has to be called, which accepts a CdataAction: enum CdataAction { Cdata, BogusComment } the variants of which correspond exactly to the possible outcomes of the third condition of the 'Markup declaration open state'. Removing this method also has the added benefit that the DefaultEmitter is now again spec-compliant, which lets us expose it again in the next commit in good conscience (previously it just hard-coded the method implementation to return false, which is why I had removed the DefaultEmitter from the public API in the last release).

2023-09-03docs: fix typoMartin Fischer

2023-08-19break!: remove DefaultEmitter from public APIMartin Fischer
2023-08-19fix!: add adjusted_current_node_present_and_not_in_html_namespace to EmitterMartin Fischer
2023-08-19docs: correct `a HTML` to `an HTML` and fix 2 typosMartin Fischer
2023-08-19docs: link multipage version of HTML specMartin Fischer
2023-08-19chore: use link reference definitions in MarkdownMartin Fischer
2023-08-19feat!: add span and offsets to DoctypeMartin Fischer
2023-08-19chore: use let...elseMartin Fischer
2023-08-19break!: rename doctype _identifier methods/fields to _idMartin Fischer
Just a bit more succinct. And now rustdoc also no longer cuts off the names of these Emitter methods in its sidebar.
2023-08-19break!: replace set_doctype_* methods with init_ methodsMartin Fischer
2023-08-19feat: make attribute value syntax recognizableMartin Fischer
Note that while making this breaking change, we're also swapping the parameter order for more consistency so that the reader parameter always comes last in Emitter methods.
2023-08-19perf: only store start offsets for attribute spansMartin Fischer
This spares us two usizes per AttrInternal<Range<usize>>. So on a 64 bit target where a usize is 8 bytes this spares us 16 bytes of memory per attribute (if spans are enabled, ... for Token<()> this obviously doesn't change anything). And the DefaultEmitter now also no longer has to update the spans on each Emitter::push_attribute_(name|value) call. The spans are now calculated on demand by the Attribute methods, which is fine since the assumption is that API users are only interested in a few specific spans (rather than all spans).
2023-08-19chore: clarify variable namesMartin Fischer
2023-08-19break!: introduce AttributeMapMartin Fischer
This has a number of benefits: * it hides the implementation of the map * it hides the type used for the map values (which lets us e.g. change name_span to name_offset while still being able to provide a convenient `Attribute::name_span` method.) * it lets us provide convenience impls for the map such as `FromIterator<(String, String)>`
2023-08-19chore: move Attribute to attr moduleMartin Fischer
This is done separately so that the following commit has a cleaner diff.
2023-08-19feat!: add all-inclusive spans to tagsMartin Fischer
Also more performant since we no longer have to update the name span on every Emitter::push_tag_name call.
2023-08-19docs: add warning to DefaultEmitterMartin Fischer
2023-08-19fix: fix lots of position off-by-onesMartin Fischer
Previously the PosTrackingReader always mysteriously subtracted 1 from the current position ... this wasn't sound at all ... the machine just happens to often call `Tokenizer::unread_char` ... but not always. E.g. for proper comments it didn't which resulted in their offset and spans being off-by-one, which is fixed by this commit (see test_spans.rs).
2023-08-19refactor!: make Emitter generic over offset instead of readerMartin Fischer
Emitters should not have access to the reader at all. Also the current position of the reader, at the time an Emitted method is called, very much depends on machine implementation details such as if `Tokenizer::unread_char` is used. Having the Emitter methods take offsets lets the machine take care of providing the right offsets, as evidenced by the next commit.
2023-08-19feat!: add offset to commentsMartin Fischer
2023-08-19refactor!: remove Span trait, just use RangeMartin Fischer
`std::mem::size_of::<Range<NoopOffset>>()` is 0 so there's no need to abstract over Range.
2023-08-19refactor!: make Position generic over offset typeMartin Fischer
Previously Span was generic over R just so that it could provide the method: fn from_reader(reader: &R) -> Self; and properly implementing that method again relied on R implementing the Position trait: impl<P: Position> Span<P> for Range<usize> { .. } which was a very roundabout and awkward way of doing things. It makes much more sense to make the Position trait generic over the return type of its method (which previously always had to be usize). Which lets us provide a blanket implementation: impl<R: Reader> Position<NoopOffset> for R { .. }
2023-08-19refactor: add default for S type param of DefaultEmitterMartin Fischer
2023-08-19refactor!: remove current_is_appropriate_end_tag_token from EmitterMartin Fischer
2023-08-19docs: remove `crate::` from link labelsMartin Fischer
2023-08-19docs: move `produce ("emit")` clue to Emitter docMartin Fischer
2023-08-19break!: merge Tokenizer::new_with_emitter into Tokenizer::newMartin Fischer
The Tokenizer does not perform any state switching, since proper state switching requires a feedback loop between tokenization and DOM tree building. Using the Tokenizer directly therefore is a bit of a pitfall, since you might not expect it to e.g. tokenize `<script><b>` as: StartTag(StartTag { name: "script", .. }) StartTag(StartTag { name: "b", .. }) Since we don't want to make walking into pitfalls particularly easy, this commit changes the Tokenizer::new method so that you have to specify the Emitter. Since this makes new_with_emitter redundant it is removed.
