* Updated baseline
JSDoc typedefs don't actually have hosts, because they're not
semantically attached to a declaration. However, the parser still
attaches them to some declaration (or statement), but that declaration
is not related to the typedef.
Previously, delayedBindJSDocTypedefTag used getJSDocHost to walk past
the unrelated declaration, but #41858 correctly started categorising
typedefs as unattached, with no host, so the binder began falling
back to file scope.
The path to skip the unrelated declaration is always the same, though, so this
PR uses `typeAlias.parent.parent` instead of `getJSDocHost(typeAlias)`.
* Add jsdoc to if statements
This should only happen in JS files, however, and there needs to be some
conditional handling of jsdoc on statements that can't have jsdoc in TS
files.
* Finish change
* Add test
* Corrected parsing for decorators on 'this' parameters
* Moved checking to parser and added a specific test
* Remove unrelated checker.ts blank line
* Missed some baseeline updates...
* If target:esnext,then useDefineForClassFields: true will now be the default.
* Added error if a private identifier is used in a static a initializer if target:ESNext and useDefineForClassFields:false.
* Added test for new useDefineForClassFields default and error message.
* Fixed tests after changing the default of useDefineForClassFields to true for target esnext
* Fixed code review suggestions.
* Updated error message.
* Added missing static check for the containing property. Fixed other code review issues.
* Allow redeclaring CommonJS alias with initial undefined
This allows us to read our own output, plus the times when people
manually write exactly the same pattern.
Fixes#40555
* Use control flow to type commonjs exports
1. Could probably use a *lot* more tests.
2. getTypeOfAlias redoes some work from resolveAlias because it needs to
not resolve the alias completely, just to its export.
* fix lint, improve jsdoc
* Add tests, improve+fix control flow
1. Update the module.exports test to match the exports ones.
2. Add a test of evolving commonjs type.
3. Add a test of assignment as last statement.
(1) exposed a bug that required a better synthetic reference. (3)
exposed a bug that was most easily fixed by giving source files a
`endFlowNode` like functions and setting it in the binder.

* Revert "Revert "Editor support for link tag (#41877)" (#43302)"
This reverts commit 451d4354b9.
* Fix parsing @link at end of comment
* Parse comments as string when no @link occurs
* fix lint
* Narrow type variables with union constraints when merited by contextual type
* Narrow generics with union type constraints as indicated by contextual type
* Accept new baselines
* Add tests
* Fix circularity for JSX elements
* Remove unnecessary isConstraintPosition information from flow cache key
* Update comment
* Add additional tests
* Rename to getNarrowableTypeForReference, remove getConstraintForLocation
* Add comment
* Fix removal of undefined in destructurings with initializers
* Use getContextFreeTypeOfExpression in discriminateContextualTypeByObjectMembers
* In obj[x], use constraint of obj's type only when x's type is non-generic
* Add comment
* Initial scribbles
* Compiles but provides spans instead of location pairs
Probably need to fork the services/server types and provide a conversion
with Session.toFileSpan. Not sure where to put the conversion.
* Switch to DocumentSpan
In theory this is already better supported, but not sure practise bears
that out.
* Builds w/protocol types + conversions
* cleanup:better names and scrub TODOs
* fix test harness too
* Misc
1. Simplify protocol after talking to @mjbvz.
2. Add more tests.
3. Initial notes about where to add parsing.
* Parse and store links in the compiler
The text of the link is still stored in the comment text, but that's now
kept in an object instead of just a string. Each link has the parse for
the entity reference, if there is one.
Needs lots more tests -- this just makes all the existing jsdoc tests
pass.
* more tests and some fixes
* Fix other failing tests
* fix bad merge
* polish parser
* improve names and array types
* slight tweaks
* remove some done TODOs
* more tests + resulting fixes
* add+fix cross-module tests
* Support `@see {@link`
Plus find-all-refs support equivalent to @see's.
* add server test
* Make comments actually part of the AST
* Add span for link.name in language service/protocol
* Make checker optional in getJSDocTags
Also change to JSDocCommentText from JSDocCommentComment
* Use getTokenValue instead of getTokenText
Measure twice, slice once
* Add missing support for top-level links
The language service and protocol were missing support for top-level
links. This commit adds that plumbing.
* add string back to comment type in node constructors
* Full parse of link tags and jsdoc comment text
- Doesn't pass fourslash yet, I'm going to switch to baselines for
failures there.
- Still needs some work on the protocol to convert file+offset to
file+line+offset.
* fix lint
* Fix missing newlines in inferFromUsage codefix
* Parse jsdoc comments as text node/link array
And switch to line+character offsets in the protocol
* Fix fourslash tests
Mostly ones that can't be baselined, but I switched a couple more over
to baselines
* Improve types and documentation
* Test+fix @link emit, scrub other TODOs
* update API baselines
* test that goto-def works with @link
* Split link displaypart into 3
One for link prefix and suffix, one for link name, and one for link
text.
* update baselines
* Provide JSDocTagInfo.text: string to full clients by default
Instead of upgrading them to displayparts.
* Real server tests
* Disambiguate {@link} and @param x {type}
They are ambiguous; previously the parser preferred the type
interpretation, but will now look ahead and parse links instead when the
prefix is `{@link`.
* Add explanatory comment in test
* fix location in richResponse in protocol
* update API baseline
* Address PR comments
1. Add a cross-file goto-def test.
2. Switch from per-message args to UserPreference.
* use arraysEqual from core
* Fix property name bindings for class expr in loops
* Fix block-scope capturing with prop initializers

This was caused by the fact that getTypeWithFacts(resultType, TypeFacts.NEUndefinedOrNull) will return never both if resultType was already never and if resultType does not contain undefined or null. In the latter case returning the declaring type is correct, in the former case this causes something narrowed to never to still be typed as the original declared type.
* Improve @template lookup and resilience
1. @template parsing may produce a template tag with a type parameter
whose name is the missing identifier. These tags should be skipped
in the checker because they receive an error in the parser.
2. The fix in #37819 was incorrect; there's no such thing as a type
parameter declared on a variable declaration. Instead, there needs to be a type
parameter declared on a jsdoc comment, because that's the scope for tags
like `@return` and `@typedef`.
There are 3 tests because either fix (1) and (2) fix the first test's
failure, but both are required to fix the last two tests' failures.
* remove containsParseError call
e350c357 (#40228) introduced a subtle bug: it switched the flags to an
alias, dropping `SymbolFlags.Property` --- and that makes
`symbolIsValue()` get to the `resolveAlias(symbol)` call, which leads to
`getPropertyOfType()` with`resolved.callSignatures`+`constructSignatures`
being `undefined`. So initialize them in `setStructuredTypeMembers`
before calling `getNamedMembers()`.
Fixes#42350
* @typedef: Improve error spans from declaration emit
This is a proof-of-concept fix. I think it could be expanded for all of
jsdoc, but I only set it up for jsdoc type aliases. It could use a lot
of polish too.
* track error node in isSymbolAccessible instead
* Switch to using enclosingDeclaration
Remove trueErrorNode
* add test of @callback and @enum
* Better error + fix @enum error
Since enums don't have a name property, you *have* to call
`getNameOfDeclaration` to go looking through the AST for one.
* Support Top Level "for await of".
* Add test cases for top level "for await of".
* Apply suggestions from code review
* add test cases
* remove redundant variables
* fix test baselines
* Update diagnostic message and tests

This program would previously fail if `x` was an export alias.
Fixes#41422
* Support xml namespace prefix for JSX elements and attributes
Just as with the `-` character, `:` is now also treated specially in JSX
element and attribute names, but is only allowed a single time, and not
at the beginning or end of the name, as is specified in the JSX spec.
All tests in jsxInvalidEsprimaTestSuite still fail, but for slightly
different reasons now. Two lines in jsxEsprimaFbTestSuite were
uncommented as they included elements with namespaces, and they now pass
without error.
* Add case for colons at ends of identifier
* Add case for jsx namepsace intrinsics
* Add cases with upcase idents for jsx namespaces
* Add case for jsx namespaces with react option
* Always consider jsx names with colon to be intrinsics
* Adjust comment about chars valid in jsx names but not js idents
* Fix minor typo in namespace prefix test case variable name
* Remove misleading comments on isUnhyphenatedJsxName
