Use `emit()` for writing `questionDotToken`, leading to properly calling
the emit hooks (which `emitTokenWithComment` doesn't) and printing the
comments. This fixes#35372 by calling its hooks to set the `.__pos`
and `.__end` fields.
Also, remove `getDotOrQuestionDotToken` which was used only here --
mainly because it seems likely to encourage misusing the
`questionDotToken` again.
Also, fix a bunch of `visitor` -> `tokenVisiton` calls in
`visitorPublic.ts`.
* Treat never-like intersections as never
* Accept new baselines
* Fix compiler issues revealed by increased intersection correctness
* Delete fourslash tests that are no longer applicable
* Include isNeverLikeIntersection check in getNormalizedType
* Erase never-like types in several more places
* Check that base types are not never-like
* Add comments
* Revert isNeverLikeType check in getIndexType (keyof shouldn't resolve member types)
* Introduce getReducedType for union and intersection types
* Don't reduce in getApparentType
* Avoid relationship check in resolveMappedTypeMembers
* Accept new baselines
* Don't call getReducedType in getIndexType
* Ensure reduced and unreduced forms of a type can compare identical
* Reduce types before converting them to string representation
* Accept new baselines
* Reduce intersections before obtaining keyof X
* Add tests
* Accept new baselines
* Fix comment in tests
* Don't infer from empty intersection types
* Add tests
* Accept new baselines
* Defer instantiation of mapped type property types
* Accept new baselines
* Include more precise type in diagnostic
* Accept new baselines
* Minor optimization
* Improve error message
* Optional properties in intersections are never discriminants
* Hoist initial assignment to exported names in cjs to they are not blocked by bindings made by __exportStar
* Copy hoisted identifiers so they do not create sourcemaps
* Accept updated baselines
* Exempt ambient [#]private from unused error
These declarations exist to create nominality so they _must_ be unused.
There should be no error for them.
* Switch to fourslash test
I don't know how to baseline suggestion diagnostics in the compiler
tests.
* Fix tests when there are project references but has disableSourceOfProjectReferenceRedirect
* Handle getScriptVersion correctly to ensure program structure is checked correctly
Fixes#36748
* Harness's language service host doesnt have getProjectVersion.
This means earlier we were creating fresh program everytime we did LS operation
Now we reuse same program, so quick info depends on order of quickinfo demands
* Because same program is used, it unvails a bug that if `export=` is evaluated before finding references, it cant find all definitions from the merge
* Update src/server/project.ts

* Adds floating block comments to the outlining spans response
* Only use one route for grabbing outline nodes, which now includes special casing the EOF token
JSDocNamepaths span a lot of identifiers that we don't actually care
about, so it's incorrect for createChildren to add its children as
synthetic nodes.
* Add/convert to failing tests.
* Stop offering to convert single string literals to template expressions.
* Ensure we're actually testing for single quotes.
* Refactor fix-all-missing-imports to be reusable by other codefixes
* Migrate infer-from-usage to use ImportAdder
* Add infer from usage test importing more than one thing in a single fix
* Migrate implement interface / abstract members fixes to use ImportAdder
* Update old tests
* Use type-only imports when it would be an error not to
* Add another test
* Rename stuff
* Fix jsdoc comment parsing initial state
Jsdoc comment parsing can be invoked in two modes:
1. top-level parsing, for comments not inside a tag.
2. tag parsing, for comment that occur after the semantic parts of a
tag.
Top-level parsing skips an initial * because it assumes that it is starting
at the very beginning of a JSDoc comment. Tag parsing does not.
The two modes are distinguished by an optional second parameter named
`margin`. When `margin` is provided, it provides an initial indent used
for comment alignment.
Previously, the check for `margin` was a truthy check `if (margin)`.
This check incorrectly treats `margin=""` the same as
`margin=undefined`.
This PR changes the check to `if (margin !== undefined)`, which
correctly treats `margin=""` the same as `margin=" "`.
* Fixes for broken tests
1. Use SawAsterisk start state.
2. @template needs to skip asterisk in addition to whitespace while
parsing type parameter names.
* undo code move
* WIP on making the JSX text node not include whitespace
* Scans to the last newline for JSX correctly
* Handle JSX closing element wrapping
* Offload all jsx text indentation handling to indentMultilineCommentOrJsxText
* Switch from find node -> find inde in formatting

* Allow 'find references' to work on most declaration keywords
* Add support for rename
* Add more keywords, move logic out of checker and into services
* Add additional type and expression keywords
Handle private identifiers little better by creating token for private identifier when its just #
Report same error as invalid character but from language service we can now provide completions for this.#
Fixes#36367, #36250
