* Add/convert to failing tests.
* Stop offering to convert single string literals to template expressions.
* Ensure we're actually testing for single quotes.
* add tests but not baselines or fixes
* Update original change
Still probably wrong; probably doesn't even compile beacuse I'm just
typing on my laptop.
* fix error code ok
* notes to self
* Error: property is specified more than once via spread
* make jsx tests stricter
* update semicolon error message
* use ?. because it is great
* use maybeTypeOfKind in new code
* restore jsx error
* add tests
* 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 when files get checked in different orders
* Fix interface extends clause
* Fix import= something type only from a module
* Revert apparently unnecessary addition
* Revert "Revert apparently unnecessary addition"
This reverts commit 7444b0b72ea2e628ff414b675ef42723a6a7695d.
* Disallow `import = a.b.c` on anything with type-only imports
* Safety first
* Add test for TS Server single-file open
* Add big comment
* Extract error reporting function for import aliases
* Delete blank line
* Un-export, comment, and colocate some utils
* Combine 3 type-only marking function calls into one
* Add more export default tests
* Class fields w/esnext+[[Define]]:no shadow error
With useDefineForClassFields: true and ESNext target, initializer
expressions for property declarations are evaluated in the scope of
the class body and are permitted to reference parameters or local
variables of the constructor. This is different from classic
Typescript behaviour, with useDefineForClassFields: false. There,
initialisers of property declarations are evaluated in the scope of
the constructor body.
Note that when class fields are accepted in the ECMAScript
standard, the target will become that year's ES20xx
* add negative test case
* Add explanatory comment
Previously subtypes of Error extended Error, but the matching subtypes
of ErrorConstructor did not extend ErrorConstructor. The members in
es5.d.ts are identical, so there's no need except for allowing interface
merging into ErrorConstructor to affect subtypes as well.
Previously the jsdoc index signature syntax was incorrectly treated the
same as Object:
```js
/** @typedef {Object} AllowsNesting
* @property ... */
/** @typedef {Object.<string,string>} IncorrectlyAllowsNesting */
```
Fixes#34911
* Add constructor functions to aliasable expressions
Fixes#35228, at least the crash. There are still a couple of errors
that are probably incorrect.
Note that isJSConstructor relies on parent pointers and the ability to
merge symbols, so I had to move isAliasSymbolDeclaration (back?) to the
checker.
* add simple test case
* remove errors in test
* fix bad merge
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
